Updates : |
|||
- number of grooves calculated according to focal length |
|||
- useful ressources and comments |
|||
|
|||
Very useful ressource : |
|||
http://astrojargon.net/MaskGenerator.aspx |
|||
|
|||
The general rule to holes width is f/s=150-200, |
|||
where : |
|||
f is focal length, |
|||
s is hole step size. |
|||
So for telescope with 1500mm focal length the step size is 1500/150=10mm |
|||
(5mm hole, 5mm for uncut space). |
|||
If holes become too small the formula becomes 3f/s=150-200. |
|||
eg for 800mm scope you need to cut 2400/s=200 s=2400/200=12mm |
|||
(6mm cut +6mm uncut). |
|||
The angled cuts are placed at 40 degrees to each other. |

GNU GENERAL PUBLIC LICENSE |
|||
Version 2, June 1991 |
|||
|
|||
Copyright (C) 1989, 1991 Free Software Foundation, Inc., |
|||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA |
|||
Everyone is permitted to copy and distribute verbatim copies |
|||
of this license document, but changing it is not allowed. |
|||
|
|||
Preamble |
|||
|
|||
The licenses for most software are designed to take away your |
|||
freedom to share and change it. By contrast, the GNU General Public |
|||
License is intended to guarantee your freedom to share and change free |
|||
software--to make sure the software is free for all its users. This |
|||
General Public License applies to most of the Free Software |
|||
Foundation's software and to any other program whose authors commit to |
|||
using it. (Some other Free Software Foundation software is covered by |
|||
the GNU Lesser General Public License instead.) You can apply it to |
|||
your programs, too. |
|||
|
|||
When we speak of free software, we are referring to freedom, not |
|||
price. Our General Public Licenses are designed to make sure that you |
|||
have the freedom to distribute copies of free software (and charge for |
|||
this service if you wish), that you receive source code or can get it |
|||
if you want it, that you can change the software or use pieces of it |
|||
in new free programs; and that you know you can do these things. |
|||
|
|||
To protect your rights, we need to make restrictions that forbid |
|||
anyone to deny you these rights or to ask you to surrender the rights. |
|||
These restrictions translate to certain responsibilities for you if you |
|||
distribute copies of the software, or if you modify it. |
|||
|
|||
For example, if you distribute copies of such a program, whether |
|||
gratis or for a fee, you must give the recipients all the rights that |
|||
you have. You must make sure that they, too, receive or can get the |
|||
source code. And you must show them these terms so they know their |
|||
rights. |
|||
|
|||
We protect your rights with two steps: (1) copyright the software, and |
|||
(2) offer you this license which gives you legal permission to copy, |
|||
distribute and/or modify the software. |
|||
|
|||
Also, for each author's protection and ours, we want to make certain |
|||
that everyone understands that there is no warranty for this free |
|||
software. If the software is modified by someone else and passed on, we |
|||
want its recipients to know that what they have is not the original, so |
|||
that any problems introduced by others will not reflect on the original |
|||
authors' reputations. |
|||
|
|||
Finally, any free program is threatened constantly by software |
|||
patents. We wish to avoid the danger that redistributors of a free |
|||
program will individually obtain patent licenses, in effect making the |
|||
program proprietary. To prevent this, we have made it clear that any |
|||
patent must be licensed for everyone's free use or not licensed at all. |
|||
|
|||
The precise terms and conditions for copying, distribution and |
|||
modification follow. |
|||
|
|||
GNU GENERAL PUBLIC LICENSE |
|||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|||
|
|||
0. This License applies to any program or other work which contains |
|||
a notice placed by the copyright holder saying it may be distributed |
|||
under the terms of this General Public License. The "Program", below, |
|||
refers to any such program or work, and a "work based on the Program" |
|||
means either the Program or any derivative work under copyright law: |
|||
that is to say, a work containing the Program or a portion of it, |
|||
either verbatim or with modifications and/or translated into another |
|||
language. (Hereinafter, translation is included without limitation in |
|||
the term "modification".) Each licensee is addressed as "you". |
|||
|
|||
Activities other than copying, distribution and modification are not |
|||
covered by this License; they are outside its scope. The act of |
|||
running the Program is not restricted, and the output from the Program |
|||
is covered only if its contents constitute a work based on the |
|||
Program (independent of having been made by running the Program). |
|||
Whether that is true depends on what the Program does. |
|||
|
|||
1. You may copy and distribute verbatim copies of the Program's |
|||
source code as you receive it, in any medium, provided that you |
|||
conspicuously and appropriately publish on each copy an appropriate |
|||
copyright notice and disclaimer of warranty; keep intact all the |
|||
notices that refer to this License and to the absence of any warranty; |
|||
and give any other recipients of the Program a copy of this License |
|||
along with the Program. |
|||
|
|||
You may charge a fee for the physical act of transferring a copy, and |
|||
you may at your option offer warranty protection in exchange for a fee. |
|||
|
|||
2. You may modify your copy or copies of the Program or any portion |
|||
of it, thus forming a work based on the Program, and copy and |
|||
distribute such modifications or work under the terms of Section 1 |
|||
above, provided that you also meet all of these conditions: |
|||
|
|||
a) You must cause the modified files to carry prominent notices |
|||
stating that you changed the files and the date of any change. |
|||
|
|||
b) You must cause any work that you distribute or publish, that in |
|||
whole or in part contains or is derived from the Program or any |
|||
part thereof, to be licensed as a whole at no charge to all third |
|||
parties under the terms of this License. |
|||
|
|||
c) If the modified program normally reads commands interactively |
|||
when run, you must cause it, when started running for such |
|||
interactive use in the most ordinary way, to print or display an |
|||
announcement including an appropriate copyright notice and a |
|||
notice that there is no warranty (or else, saying that you provide |
|||
a warranty) and that users may redistribute the program under |
|||
these conditions, and telling the user how to view a copy of this |
|||
License. (Exception: if the Program itself is interactive but |
|||
does not normally print such an announcement, your work based on |
|||
the Program is not required to print an announcement.) |
|||
|
|||
These requirements apply to the modified work as a whole. If |
|||
identifiable sections of that work are not derived from the Program, |
|||
and can be reasonably considered independent and separate works in |
|||
themselves, then this License, and its terms, do not apply to those |
|||
sections when you distribute them as separate works. But when you |
|||
distribute the same sections as part of a whole which is a work based |
|||
on the Program, the distribution of the whole must be on the terms of |
|||
this License, whose permissions for other licensees extend to the |
|||
entire whole, and thus to each and every part regardless of who wrote it. |
|||
|
|||
Thus, it is not the intent of this section to claim rights or contest |
|||
your rights to work written entirely by you; rather, the intent is to |
|||
exercise the right to control the distribution of derivative or |
|||
collective works based on the Program. |
|||
|
|||
In addition, mere aggregation of another work not based on the Program |
|||
with the Program (or with a work based on the Program) on a volume of |
|||
a storage or distribution medium does not bring the other work under |
|||
the scope of this License. |
|||
|
|||
3. You may copy and distribute the Program (or a work based on it, |
|||
under Section 2) in object code or executable form under the terms of |
|||
Sections 1 and 2 above provided that you also do one of the following: |
|||
|
|||
a) Accompany it with the complete corresponding machine-readable |
|||
source code, which must be distributed under the terms of Sections |
|||
1 and 2 above on a medium customarily used for software interchange; or, |
|||
|
|||
b) Accompany it with a written offer, valid for at least three |
|||
years, to give any third party, for a charge no more than your |
|||
cost of physically performing source distribution, a complete |
|||
machine-readable copy of the corresponding source code, to be |
|||
distributed under the terms of Sections 1 and 2 above on a medium |
|||
customarily used for software interchange; or, |
|||
|
|||
c) Accompany it with the information you received as to the offer |
|||
to distribute corresponding source code. (This alternative is |
|||
allowed only for noncommercial distribution and only if you |
|||
received the program in object code or executable form with such |
|||
an offer, in accord with Subsection b above.) |
|||
|
|||
The source code for a work means the preferred form of the work for |
|||
making modifications to it. For an executable work, complete source |
|||
code means all the source code for all modules it contains, plus any |
|||
associated interface definition files, plus the scripts used to |
|||
control compilation and installation of the executable. However, as a |
|||
special exception, the source code distributed need not include |
|||
anything that is normally distributed (in either source or binary |
|||
form) with the major components (compiler, kernel, and so on) of the |
|||
operating system on which the executable runs, unless that component |
|||
itself accompanies the executable. |
|||
|
|||
If distribution of executable or object code is made by offering |
|||
access to copy from a designated place, then offering equivalent |
|||
access to copy the source code from the same place counts as |
|||
distribution of the source code, even though third parties are not |
|||
compelled to copy the source along with the object code. |
|||
|
|||
4. You may not copy, modify, sublicense, or distribute the Program |
|||
except as expressly provided under this License. Any attempt |
|||
otherwise to copy, modify, sublicense or distribute the Program is |
|||
void, and will automatically terminate your rights under this License. |
|||
However, parties who have received copies, or rights, from you under |
|||
this License will not have their licenses terminated so long as such |
|||
parties remain in full compliance. |
|||
|
|||
5. You are not required to accept this License, since you have not |
|||
signed it. However, nothing else grants you permission to modify or |
|||
distribute the Program or its derivative works. These actions are |
|||
prohibited by law if you do not accept this License. Therefore, by |
|||
modifying or distributing the Program (or any work based on the |
|||
Program), you indicate your acceptance of this License to do so, and |
|||
all its terms and conditions for copying, distributing or modifying |
|||
the Program or works based on it. |
|||
|
|||
6. Each time you redistribute the Program (or any work based on the |
|||
Program), the recipient automatically receives a license from the |
|||
original licensor to copy, distribute or modify the Program subject to |
|||
these terms and conditions. You may not impose any further |
|||
restrictions on the recipients' exercise of the rights granted herein. |
|||
You are not responsible for enforcing compliance by third parties to |
|||
this License. |
|||
|
|||
7. If, as a consequence of a court judgment or allegation of patent |
|||
infringement or for any other reason (not limited to patent issues), |
|||
conditions are imposed on you (whether by court order, agreement or |
|||
otherwise) that contradict the conditions of this License, they do not |
|||
excuse you from the conditions of this License. If you cannot |
|||
distribute so as to satisfy simultaneously your obligations under this |
|||
License and any other pertinent obligations, then as a consequence you |
|||
may not distribute the Program at all. For example, if a patent |
|||
license would not permit royalty-free redistribution of the Program by |
|||
all those who receive copies directly or indirectly through you, then |
|||
the only way you could satisfy both it and this License would be to |
|||
refrain entirely from distribution of the Program. |
|||
|
|||
If any portion of this section is held invalid or unenforceable under |
|||
any particular circumstance, the balance of the section is intended to |
|||
apply and the section as a whole is intended to apply in other |
|||
circumstances. |
|||
|
|||
It is not the purpose of this section to induce you to infringe any |
|||
patents or other property right claims or to contest validity of any |
|||
such claims; this section has the sole purpose of protecting the |
|||
integrity of the free software distribution system, which is |
|||
implemented by public license practices. Many people have made |
|||
generous contributions to the wide range of software distributed |
|||
through that system in reliance on consistent application of that |
|||
system; it is up to the author/donor to decide if he or she is willing |
|||
to distribute software through any other system and a licensee cannot |
|||
impose that choice. |
|||
|
|||
This section is intended to make thoroughly clear what is believed to |
|||
be a consequence of the rest of this License. |
|||
|
|||
8. If the distribution and/or use of the Program is restricted in |
|||
certain countries either by patents or by copyrighted interfaces, the |
|||
original copyright holder who places the Program under this License |
|||
may add an explicit geographical distribution limitation excluding |
|||
those countries, so that distribution is permitted only in or among |
|||
countries not thus excluded. In such case, this License incorporates |
|||
the limitation as if written in the body of this License. |
|||
|
|||
9. The Free Software Foundation may publish revised and/or new versions |
|||
of the General Public License from time to time. Such new versions will |
|||
be similar in spirit to the present version, but may differ in detail to |
|||
address new problems or concerns. |
|||
|
|||
Each version is given a distinguishing version number. If the Program |
|||
specifies a version number of this License which applies to it and "any |
|||
later version", you have the option of following the terms and conditions |
|||
either of that version or of any later version published by the Free |
|||
Software Foundation. If the Program does not specify a version number of |
|||
this License, you may choose any version ever published by the Free Software |
|||
Foundation. |
|||
|
|||
10. If you wish to incorporate parts of the Program into other free |
|||
programs whose distribution conditions are different, write to the author |
|||
to ask for permission. For software which is copyrighted by the Free |
|||
Software Foundation, write to the Free Software Foundation; we sometimes |
|||
make exceptions for this. Our decision will be guided by the two goals |
|||
of preserving the free status of all derivatives of our free software and |
|||
of promoting the sharing and reuse of software generally. |
|||
|
|||
NO WARRANTY |
|||
|
|||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
|||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
|||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
|||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
|||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
|||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
|||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
|||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
|||
REPAIR OR CORRECTION. |

|

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
|||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
|||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
|||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
|||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
|||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
|||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
|||
POSSIBILITY OF SUCH DAMAGES. |
|||
|
|||
END OF TERMS AND CONDITIONS |
|||
|
|||
How to Apply These Terms to Your New Programs |
|||
|
|||
If you develop a new program, and you want it to be of the greatest |
|||
possible use to the public, the best way to achieve this is to make it |
|||
free software which everyone can redistribute and change under these terms. |
|||
|
|||
To do so, attach the following notices to the program. It is safest |
|||
to attach them to the start of each source file to most effectively |
|||
convey the exclusion of warranty; and each file should have at least |
|||
the "copyright" line and a pointer to where the full notice is found. |
|||
|
|||
<one line to give the program's name and a brief idea of what it does.> |
|||
Copyright (C) <year> <name of author> |
|||
|
|||
This program is free software; you can redistribute it and/or modify |
|||
it under the terms of the GNU General Public License as published by |
|||
the Free Software Foundation; either version 2 of the License, or |
|||
(at your option) any later version. |
|||
|
|||
This program is distributed in the hope that it will be useful, |
|||
but WITHOUT ANY WARRANTY; without even the implied warranty of |
|||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
|||
GNU General Public License for more details. |
|||
|
|||
You should have received a copy of the GNU General Public License along |
|||
with this program; if not, write to the Free Software Foundation, Inc., |
|||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. |
|||
|
|||
Also add information on how to contact you by electronic and paper mail. |
|||
|
|||
If the program is interactive, make it output a short notice like this |
|||
when it starts in an interactive mode: |
|||
|
|||
Gnomovision version 69, Copyright (C) year name of author |
|||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
|||
This is free software, and you are welcome to redistribute it |
|||
under certain conditions; type `show c' for details. |
|||
|
|||
The hypothetical commands `show w' and `show c' should show the appropriate |
|||
parts of the General Public License. Of course, the commands you use may |
|||
be called something other than `show w' and `show c'; they could even be |
|||
mouse-clicks or menu items--whatever suits your program. |
|||
|
|||
You should also get your employer (if you work as a programmer) or your |
|||
school, if any, to sign a "copyright disclaimer" for the program, if |
|||
necessary. Here is a sample; alter the names: |
|||
|
|||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
|||
`Gnomovision' (which makes passes at compilers) written by James Hacker. |
|||
|
|||

|||
|
|||
This General Public License does not permit incorporating your program into |
|||
proprietary programs. If your program is a subroutine library, you may |
|||
consider it more useful to permit linking proprietary applications with the |
|||
library. If this is what you want to do, use the GNU Lesser General |
|||
Public License instead of this License. |
