My astronomy projects DIY

This is for you that think it's better to spend time then money on your hobbies.

Be careful if you want to do something similar as I do here. I do many mistakes and what's right for me can be wrong for you and your equipment, you can destroy it!

My full frame camera needs a bigger flattener to reduce the vignetting. This time I built my flattener system from a 3" x1 Altair Planostar Flattener.

To my new transportable mount I need some shorter focal length lens. A Sigma APO 150mm f2.8 maybe. I did some simple test how the vignetting looks.

Making of battery box and astroserver

Project: Battery box and astro server

Now including both version 1 and version 2.

Batterybox and astroserver

This is my second attempt to build an astroserver with a Raspberry. Now I use the much faster Raspberry Pi4:

Project: Raspberry Pi4 for Astronomy
Raspberry Pi4 for Astronomy

Old project:
I'm sure many as I have thought about those small Raspberry computers and if they can be used as an astroserver. Can an old Windows guy like me learn how to build and use one?

Project: Raspberry for Astronomy

This project didn't perform very well, mostly because of the slow computer.
