I picked up a 6 inch dob at a government auction real cheap - $22
It is a Meade Starfinder. Not a super quality scope, but... the optics appear to be pretty decent. The views in the eyepiece seem decent, there is some coma because I know I dont have the collimation down perfect yet. I did a rough collimation, but I think the secondary is off a little. I did photograph Jupiter however, it was variably cloudy tonight, but there were periods of decent viewing. Here is what I got:
Not my best images, but keep in mind this is a dob, so its totally manual with no clock drive. I imaged without a barlow, focal length is about 1200mm. It is a 6", f/8 scope. The red spot is rising in these images.
One more image where I captured 3 moons...
Notice the moons are nice and round, and quite bright.
I also think part of the problem is I think theres a setting in the camera thats off a bit. Maybe I should turn up the gamma a little, as these are way too "contrasty". I apparently did not have much saturation, there is very little color. I do believe this scope shows some promise however. I posted these images as a reference to compare to once I do more work on the scope.
