Thanks Laurie and Peter,
Yes Peter you're comments are so right and focus is an area I struggle with, inparticular with deep space objects on the SCT with a DSLR camera and multi focal lens glasses. I think that let's me down much more than anything else.
I,m able to get much better results when shooting through my ED80 as the wider field is less critical.
I,m not happy with SCT and its field curvature so would love to go to something a bit faster and with a flatter field like the GSO RC for instance, if the Tax man is kind to me this year I may invest.
Thanks very much for your honest remarks.
