Description

Here recordings from two nights were combined. All images were taken with the Hutech IDAs LPS P2 filter, which highlights the h-alpha regions in the galaxy.

I am not satisfied with the editing. In the first try the colors came out very nice, in the second try the galaxy stood out a bit better from the background. The editing was done in Adobe Photoshop.

I made a third attempt with the test version of PixInsight. The background is very noisy, probably because I don't really know the tools yet. For example I could not apply denoising with MultiLinearTransform to the 2x Drizzle image.
