Dear All,
After a frustrating week or two, I finally managed to get my new setup out into the night sky and try a bit of imaging.
I did a quick run through with K3CCDTools to sort out the polar alignment and then tried out the guiding with PHD - pretty much a flat line, certainly less than +/-1 line on the graph (which I assume means <1 pixel movement) - guiding camera is a StarShoot Autoguider - scope is a WO 70mm ZenithStar, 420mmFL.
I focused using a Bahtinov Mask on a bright star and then setup a run on Eta Carina with an unmodified Nikon D200 - 5 x 5min subs, 3x 5min darks and 5x flats. These are shot through the Tak Focal Reducer, bringing the scope back to ~f6 & FL~600mm.
I then dumped this through DSS and adjusted levels and a quick curve in PS.
I haven't tried to process this any further - far toooooooooo tired.
I'm happy with the round stars, and will try to extract some more depth from this in the morning...
Thanks Chris for selling me such a fine scope.
Cheers
David T
