Hi,
I have increased the time taken for my image however have only used the data from last night. When I put both nights together I ended up with being unable to align the stars near the corner of the image. I don't know if this is called field rotation.
Taken through a William Optics Flt 110 using a QHY-9 at -20c. Darks applied but no flats. Guided using PHD and stacked using DSS and Photoshop CS3. Lum 70 Minutes at 1x1 binning and Red 24 Min, Green 24 Min and Blue 24 Min at 2x2 binning.
I know it is a bit red and I have something on the lens or chip but still like the smoothness and I think it is my best M 16 to date.
Feel free to offer advice.
