Description

Imaged last night on 042515 at 0700 UTC. I attempted to frame and orient the image similar to that of the 2 page Virgo capture on Pg. 52 of May's Astronomy Issue.

I was really fighting all sorts of LP issues from a 46 percent illuminated Moon, thus I had to reduce my ISO setting down to 400 on my new Huetch Canon 6D to bring things under control somewhat.

I also had to perform DBE corrections in Pixinsight and perform additional gradient corrections in Photoshop CC until I finally liked the overall background of the image.

I wanted to pull up on curves more, but I couldn't due to the gradient issues.

Considering the circumstances I was happy with the outcome. The NGC's are literally all over the place in the frame from edge to edge. Many at Mag. 12 and 13.

The noise level on this camera is sooo Low just simply amazing. I took no darks for this image which really just shows how well this camera performs.
