Hi Wayne ,
Thanks for the info on DSS settings , will try them. Did you get advice on these or find them by experimenting? I use the beta version of DSS as it supports Sony ARW files. JPEGs are a lossy picture format and you lose data when you manipulate them . With the beta version of DSS you should get even better pictures. Will be able to advise you of my experience with off axis guiding when your ready. Could even show you the setup I have here in Pelaw main near kurri kurri. You said you are looking at a field derotator as well , if your handy you might try making a wedge and forget about the derotator. I had an lx90 a few years ago and was managing to get a about 60% of pictures at f6.3 , with nice round stars, unguided for 2+ minutes using a homemade wedge aligned on the asterism of stars in octanis , situated around the S celestial pole. If I had used a guider they would have been perfect.
Regards philip
