Nice job on the processing.

But I darkened it enough so it's not particularly noticeable.  I took JPG images only rather than JPG & RAW, so that doesn't help.  And only 1 hour of time.

Field of view is 2 x 1.3 deg.  M101 is offset because that's where the goto put it and I said good enough.  Turns out that was a bonus with the galaxy top center, NGC 5474, which is labeled in Starry Night Pro planetarium software as a spiral though it looks "irregular".  But I do see what look like tiny specks of star clouds in spiral arms.  There are actually at least 7 other galaxies including the one on the far left that doesn't show on Starry Night Pro.

Camera- Modified Canon T7i.  Image downs ampled 33%.

I also couldn't really process both images to look the same since I had so much more time on 3/30 than last night (5/23).  But I think you'll get the idea.

I like your shot better than mine. Duh! You didn't mention what camera it is that you used. Do tell!

 

Hola Peter, I used a one shot color camera, the ASI2600MC.   It's really a fine camera that has no amp glow.   Makes AP a little less tedious versus using the mono camera and filter wheel.   I think for regular RGB images, I may just use this camera from now on and save the mono for the narrow band imaging.  

What camera did you use?  Did you use one of your integrating video cameras?   On facebook it said you used a phone, but that seems optimistic.

Hi Terri!

I'm so glad you captured it. I debated but there's been another project I've been working on for about 6 nights now. In 30 minutes we have more opportunities!
