Description

Luca Marinelli's recently-posted  image of planetary nebula Hartl-Dengel-Weinberger 3,  taken  with a 10" f/4 Newtonian telescope over the course of a year from Schenectady, NY,  is outstanding!  It motivated me to try from my remote observatory at Dark Sky New Mexico, using an 11" RASA scope at f/2.2.  I  was not willing to spend 85 hours on target, like Luca, and so I did a trial image with the OIII filter at 6 hours exposure.  I was pleasantly surprised that it produced acceptable results.   So I duplicated that with an H-alpha filter to generate this HOO image (12 hours total time).  FOV is approximately 60 x 40 arc min (considerably cropped).  I really like Luca's RGB stars and will try to add them to this image at some later date.
