After I saw Al Kelly post an image of this object recently, I decided
I wanted to image it with emission line filters. I used Ha, [OIII] and [NII] for this object. When there's a full moon it is always fun to go after the dimmest planetaries up there using emission line filters. Sub exposures were 15 minutes binned 2x2. Each filter had 7 sub exposures. The filters were all 3nm FWHM Custom Scientific. The camera was an ST10XME, and the scope was an AP155EDF. http://www.rdcrisp.darkhorizons.org/pk164_page.htm |
