Recently I couldn't resist to buy a GSO 6" Ritchey Chretien at a special
price.
I have some tilt in the system with stars being progressively off focus on
the right side of the picture, but once I get this sorted out I guess I will
habe a nice little imaging scope. It works amazingly well with the "William
Optics X0.8 flattener II" that I recently got for my Skywatcher ED
refractors, which gives a focal lenth of 1100mm (f/7.2).
The focuser can be adjusted, so I guess I will be able to get rid of the
tilt.
"First light" was M33 as it fits the FOV rather nicely with the QHY8 camera.
This is only a "quick and dirty" processing as work is killing me, no time
for "serious stuff".
Taken from the middle of Berlin with a GSO 6" RC at f/7.2 on a G11 mount,
QHY8 camera, 39x10 minutes.
