Taa - thanks!

I was seriously pleased, very seriously pleased with my first imaging attempts even without a guider - as the OAG has a focal reducer, bringing the optics down to probably F6.5.

I targeted Eta Carina, M42, M46 then M47. Shots looked more than fine out to 6 minutes unguided. Then I did 10 and finally 20 minute guided shots of M47. It can be hard to find a guide star with a DSI - probably need a DSI II Pro, but jeeze this was fun and lovely to see pin point stars!

Well quit after 4 or 5 of the most enjoyable hours of imaging, wherein:

1. Every slew (80% remote) was spot on - and I mean dead centre of the CCD
2. Even with high cloud cover - every shot looked great, was focused (not yet colour adjusted - but hey captured RAW so do that later)
3. Tracking was great all round
4. On 80% of shots a star was captured in the OAG - and this meant tracking out to 20 minutes gave pin point stars - no trails whatsoever (but the core was blown out)
5. First time use of a focal reducer was brilliant!
