Description

The data for this image was collected over 5 nights in April and May. I wanted to both test out the new ASI2600mm and see just how nice of an image I could take with my relatively small 4" refractor before mounting it on my 12" SCT. I already have two nights of data on the larger scope and am waiting on more clear skies to finish it.

I only did a basic integration in Pixinsight and could definitely get more our of the data with more processing.
