Description

This is a cropped version of my Galaxy cluster image of the Virgo region to capture the famous Markarian chain.

About 45 min of time into this image. I shot the image a bit too hot (ISO 1600) and so had to practice some noise reduction in LR.

Longer duration and less ISO is probably the way to go.

Best regards,

Ian
