Description

I am pleased that I was able to pick out the fainter extremities of the main subject of this image NGC 3718. I ran out of time to get the same number of blue subs in case your wondering why there is less of them. Processing done mainly in PixInsight with final tweaking in Photoshop.

Version B is a cropped image.
