Hello fellow insomniacs
After an hour of cloud cover after aligning and focusing and ruining the first 5 subframes I let the camera run as there was no sign of rain and true to form with the British weather the skies cleared. I managed to get 18x10 subframes of the The Wizard in Cepheus, details are as follows
TMB 115 f7 with field flattener
Starlight Xpress SXVF H36 with FLI filter wheel using Astronomik 13nm Ha filter
Paramount ME
18 x 10 minutes unguided
Simple autodark subtraction in Maxim DL, no flats or bias frames
Aligned and combined in Maxim DL using sum
Saved to 16 bit tiff, using full pixel value and gamma value of 0.8 to stretch
2 x aggressive curves and 1 minor curves alternated with levels in Photoshop CS2
Local contrast enhancement using Noel's tools in Photoshop CS2
Clone stamp tool to tidy image
Final minor cropping to remove effects of stacking
I have also included a rotated cropped closeup of the Wizard to show the detail better.
I had to reduce the quality of the image somewhat in order to post it, better quality versions are on my site
