Seestar S50 2" optical filter adapter

This is adapter for a 2" optical filter for a Seestar S50 telescope. This part is only the inner part which fits into the lense hole. The outer part is a commerical M48 adapter (bought from SVBONY) I had these ones: https://www.amazon.de/Svbony-Verl%C3%A4ngerungsrohr-Verl%C3%A4ngerung-Brennweite-Astrofotografie/dp/B07S72HT9R

The adapter is made from TPU with shore 95A. PLA or any other will not fit!
You have to press in the M48 adapter and turn it a little bit. The thread is only for better fixing! The other end fits into the Seestar lense hole with a little bit pressure.

I did not make any picture with an external filter so far. So I don't know if it really will work. I will use an OPTOLONG l-eNhance narrow band filter. I hope the auto-focus and plate-solve will work.

Be careful at usage -> remove the adapter before shutdown of the Seestar. Disable auto-shutdown!!! Otherweise you will damage your Seestar telescope as well as your filter and adapter.
