Alnitak region widefield with old camera lens


Recommended Posts

I spent some time last night attempting to resolve an autoguiding issue, whic remains unresolved. The tandem mount had a StarlightXpress H9 mono camera fitted with a 40 year old 200mm f/4 Nikkor manual lens via a Kood adapter and with a 2" Ha filter in front of the lens via a step-down ring. I let this lot run unguided while I tackled the PHD problem, so this is the combined 11 x 3min subs before the clouds inevitably rolled in. Not bad for a lens which is effectively worthless in the second hand market - and all from light polluted London.
