Phew – thanks guys! I thought it was just me being an incompetent buffoon for struggling to auto guide with consistent quality at focal lengths of 1500mm plus! I’m so glad to be in the company of others who have had similar experiences; I feel so much better now.
Imaging at 920mm with a Vixen ED102 F9 refractor on the Vixen GPDX mount almost seems a walk in the park now!
However, I’ll keep plugging away – I like a challenge.
Cheers
Dennis
