Pacman Nebula with SV90 Raptor

This is the first picture I took with my new Stellarvue SV90 Raptor (APO triplet).

The quality of this telescope is excellent and with its carbon fiber tube, it is very lightweight.

Star diffraction pattern is textbook-like.  With the Stellarvue field flattener specially designed for the stellarvue refractors at f/d 7, stars are round and tight from center to edge.

I can see a drastic difference with the Orion 102ED I had before: even though the focal is slightly shorter, the SV90 provides much more details.  This is a pleasure to image with this telescope!

Total exposure time was almost 3 hours. Having many sub-exposures in conjunction with the CLS-CCD light pollution filter  is definitely a good way to improve the S/N ratio in my light polluted backyard…
