Description

Wanted to revive my 183 MM Pro for a mineral moon tonight but I had to wait for the moon to rise over my neighbours building. Meanwhile I thought I coud shoot the Orion Nebula with the OSC and see what I will end up with when going for 30 second subs. What shall I say! I had four minutes of data then the sky was covered with high fog. Nowcast says it will clear by midnight...So let's wait and see...

Version C: Added Ha and Lum data from 2021/02/12 after staraligning those master files to match today's data.

Thanks for watching!
