M31

[HunterHarling]

This is composed of a single 30s exposure unguided through each filter (RGB) to make a color image. The noise in this image was very difficult to deal with... but that's what happens when you don't stack🙃 For processing I did lots of noise reduction using TGV denoise, MML, and ADCNR in Pixinsight, stretch image, and curves transformation.

Very nice!

Oh how nice it would be to put your eye to an eyepiece and actually see that!

That's impressive for 30's for each RGB. Well done.

That's what I thought also. I'll have to do some observing when m31 is a bit higher.

The Andromeda Galaxy is a great target for this challenge. Big and bright...

Am I wrong or should the image be a single 30s image?  Beautiful image though.

I wouldn't be able to have a RGB image though... the individual channels are singe 30s. Also, the images aren't stacked, just color combined.
