Currently imaging NGC 1554/55 (now ... 02/04/2012 ... scattered high clouds)
NGC 2419 finished 02/02/2012
Note: Images are generally presented full frame (1530 x 1020 - not cropped). In a few instances, I have cropped an image by 8-15%, due to sequence registration issues

Processing notes for all images:
CCDStack is my ccd image processing program of choice
(I now use MaxIm DL only for controlling / guiding the ST8 / telescope)
The general CCDStack processing steps for all images are:
Calibration, bloom removal, alignment, normalization, STD Sigma reject, sum or median combine, DLP processing, 25 to 50 iterations of Positive Constraint deconvolve and save as a 16 bit scaled TIFF:
example of one unprocessed .fit image, one of 74, NGC 4096 (converted to .jpg)
example of a fully processed CCDStack image, notice the gradient, NGC 4096 (converted to .jpg)
Adobe Photoshop CS5 (new 08/2011) is my final processing program
Typical Photoshop steps are:
Curves, GradientXTerminator if needed, clean up (stars, blooms, defects, etc.), cropping when needed, selective enhancement with levels, curves, unsharp mask, or brightness/contrast, and save as JPEG for web:
