Hi Trevor
Thanks, I appreciate your comments and suggestions. The single 600 second image was taken as part of my ongoing investigation into improving my side-by-side imaging capabilities at focal lengths of over 1500mm, something which I have really struggled with.
I am pleased to report that I have made inroads into the problems, mainly by mounting the guide scope nearer to the imaging scope and by supporting the focuser of the guide scope in a guide ring. Whilst these two most recent changes have not eliminated star elongation, they have certainly contained the magnitude of it so I can now concentrate on other contributing factors.
Having to set up each night and suffering long, long periods between experimentation has really hindered my progress, but it is nice to see some real improvement at last!
Cheers
Dennis
