Astroguider : C-Mount to Pentax-K
Scope :
This is a glorified adaptor for C-Mount astronomy cameras, it mounts on a Sky Watcher dovetail with two Kodak-thread holes separated by 3 cm.
It is configured for SV Bony SV305 camera which have a 5 mm removable spacer, see next section for more information.
A Kodak-thread hand screw model is included in the files, as this kind of screw can be hard to find in Metric countries. I've found it to be sufficiently strong to use.
The standalone adapter is also included if you don't want to print the whole astro guider.
Parameters
You can modify the thread length, add or remove any spacer on the C-Mount side using the included FreeCAD spreadsheet, and by default there's an offset of to be able to focus at infinite.
Remove this offset if you intend to use it on terrestrial targets!!!
Printing
You can print it in 0.2 mm layer height, with auto-painted support and a brim. Don't put support around the threads as they are not needed and can easily lift off the bed.
Print on the thread side.
Have a good print!
