Hi,

Having received my new scope last week the weather set in, of course, and had the opportunity to take my first images over the weekend. The guide scope is a W/O Petzval 70mm as shown in the fist two photos.

All shots were taken with a Canon 400D unmodified, guided with PHD and stacked and processed using DSS and GIMP. Apart from the Lagoon all were first attempts and I could not be happier with the results and the scope. I did have issues with guiding on NGC253 as it was almost overhead and the scope did not want to guide but otherwise has been perfect.

Lagoon:11 x 7 min lights, 5 x 7 min darks at ISO 400.
NGC253:2 x 7 min lights, 2 x 7 min darks at ISO 800.
M31:5 x 6 min lights, 2 x 6 min darks at ISO 800.
Horsehead nebula:4 x 7 min lights, 2 x 7 min darks at ISO 800.

Any suggestions on how to improve processing would be greatly appreciated. Thanks for looking.

Mark.

New scope. I forgot to reduce them.

Your shots look very good. Stacking more subs will help reduce noise. I also sometime use noiseware professional which is a photoshop plugin from imagenomic and does a great job at reducing it further.
