Filter Wheel DIY

Astrofriend (Lars) · #1 14-12-2023, 01:14 AM

When having a 3D-printer it's a lot of thoughts about everything that can be 3D-printed. If I buy a monochrome camera in the future there is a need of filters and a filter wheel. It's not very dificult to design it in 3D CAD, the problem is more, will the plastic material be good enough ? At least I get it exactly as I want it.

Most people who do this buy a manual filter wheel and set a motor on it. Here I give it a try to do it all in the 3D-printer.

My filter wheel project:

As a driver for the filter wheel I will use the open source project myFilterWheel.

Added a lot of updates to the project. I have 3D-printed the wheel and chassi and it looks like something that could work.

Very interesting, Lars!
I planned to something similar, now I have renewed my enthusiasm for the project :-)

Hi Bojan,
Great, do you have the knowledge to write an INDI driver for MyFilterWheel open source project ?

Today I started with the off-axis guider that I want to built into the filter wheel.

It must be summer now at your place, can you do any astro photographing ? Here it's cold and dark, but massive clouds night after night.

Lars,
Sorry, I am not a programmer, I am RF engineer.. analog person :-)
But I am sure there will be someone on the forum that may be willing to help.
Or, it may be worth to contact OnStep community (http://www.stellarjourney.com/index....oftware_camera). OnStep has ASCOM driver, maybe INDI is also supported (not sure..).
OnSteo home page/forum is here:

Hi Bojan,
Thanks for the links. I hope to solve this by myself, need to learn that for other coming projects.

Added some more info about this off-axis guide part:
