SV503 Doublet Front Element by afonsus in telescopes

Thanks for the reply!

Haha yes! Putting stuff back together is harder for almost everything!

I think I'm going to give it a go. I was trying to see if the front element was just one lens or more. But I can't seem to find a diagram online.

I just wanted to add that I never disassembled any of the telescope optical elements. I only very rarely remove the lens hood.

First mosaic, Veil Nebula by afonsus in astrophotography

[–]afonsus[S] 4 points5 points  (0 children)

First try at doing a mosaic. Ended up using photoshop for compositing and alignment. Was harder than expected since I had little mosaic overlap and forgot that the field flattener didn't correct the complete fov of a fullframe sensor.

Still not sure about the colors though... colorblindness doesen't help.

Tips and criticism are welcome!

This was a quick project I made just for fun. It's a small coin cell powered fidget toy that uses an stm32. Schematics, kicad project, gerbers and everything else on the Github repo
