Hi Marc, just wanted to say thanks for tip on the Astronomik clip on filter for the Canon - ordered one and used it for the first time last week - half moon, and some high haze. Going to link the first 3 images, NGC7000, IC5070 and NGC 7380. Was running out of dark, so only imaged for 90min, 60min and 45 respectively. All 60 second shots. Used 1 master dark from my dark 'library' and processed with DPP, Power Stretch, Curves and luminance removal, aligned stacked in Neb 2. Finished in PSE7. Dumbfounded with results. Finally some context, texture and nice color. Many, many thanks.
Including 2 with the DBK and 8" Imaging Astrotech Newt.
