Hi Michael. Thanks for your comments. Yes, imaging in ordinary seeing is a balancing act and going to longer wavelengths can sometimes help.
Hi Paul. Thanks for your comment and feedback on the colour. I am having major trouble with colour balancing in poor seeing. The balance changes depending on the size of features, with finer features tending to go magenta - I haven't found any way to compensate without destroying the overall balance in extended regions of the image. It could possibly be CA in the Barlow, but I rather suspect that it may be something fundamental to do with the way the smallish scope aperture deals with bad seeing effects. I am also working through the processing to see if deconvolution introduces any gremlins and if there is any way to compensate for the effect - would welcome any ideas. Of course good seeing would largely fix things.
