M88 is a neat spiral galaxy in Coma Berenices that I never have imaged before. First image with the 294MC-Pro and the 8"RC back in April. I had some odd reflections that I think were caused by the ONAG. Basically above and below each bright star was a oval donut. Looked like a out of focus star. Not many of them, but I stamped them out in PS. Strangle, the background pattern that plagued my M51 and M101 image with the 8"RC @ f6 was a non-factor for this image. The big difference was I imaged at 200gain and 60s subs, so I am really not sure what to think besides more testing is needed. The camera is crazy sensitive, so I am not giving up on it. Especially after how this turned out.

 

Quick stats:

Subs:300x60s -10c 200gain(30offest) 1x1 @ -10c

Scope: 8"RC @ f/8, guided with ONAG (Lodestar X2)

Skies around 18.6 on the SQM-L

Thanks for looking!

Looking good Pete. It reminds me of M63 The Sunflower Galaxy.

Excellent image, Pete!

 

M88 ought to have nickname. It's that good. 

By the way, That certainly is a lovely triple star to the left of the galaxy. 

I have since checked out its designation. 

It's GRV 1156. 

Magnitudes: 10.5, 11.8 and 15.3. 

They look superb with M88!

 

I can count at least 5 other galaxies in your image. 

 

Kindest regards from Aubrey.

Thank you everyone for the comments! Gaston - I do have a UV/IR filter I can use for the camera. Your discussion in that tread makes total sense to me.
