Location: San Bruno, CA
Telescope: Celestron 9.25 with F/d 6.3 reducer on Takahashi NJP-Z Mount
Camera: Qhy8 CCD with Astronomik CLS CCD Filter
This is the result of 16 exposures of 330 sec. The Celestron C9.25 is really a good choice for planetary nebula given its relatively long focal length, and its large aperture.
I find also that many planetary nebula are a nice target when on a light polluted site, since they have a relatively high surface brightness.
What is more important here is to have a night with good seeing conditions, very good tracking, take multiple shots, and stack!
