Atmospheric turbulence usually create wiggly images the RGB is still intact. The barlow depending on the make cause the splitting of RGB onto the CCD sensor at different angles. I don't have a major problem with my barlow but it is noticeable when I expand the image. I have been a bit delayed but I am going to try and manipulate some of my image to show this affect. The only comparison that I am unable to replicate is the magnification which is the whole concept.
I hope one day to decide whether to go with a filter wheel and a mono camera or a Televue Extender which is specifically designed for AP, or both.
