Description

This Triband RBG Ultra filter I recently acquired gives me great satisfactions. I only had a few days available for the frames so I ended up with more or less 11h of data.
I used drizzle to improve the image scale.
Unfortunately, the fan of my camera broke, so I could only set the temperature to 0C, it was unable to reach lower temperatures! I took a while to understand the problem, it was very hot here, and at the beginning I thought that was the cause.

Only after the first stack I realised that there was something more (IFN?) in the galaxy surroundings and that I should have taken much more frames, 20+ hours ideally.
Still, this is the best picture I have on the subject, next time I'll do better!
