Please comment on your experience with the short refractor from Bresser, the AR-152S model. The good, the bad, anything really.
Here it is: Bresser AR-152S
I know its most significant drawback, the CO which is a curse of any achro and particularly the short models. I'm not too sensitive to CO, to say the least. Being on a budget I'm going to use it as a general purpose scope, for everything. Once again, I'm fine with the CO.
What I like about it is of course its light gathering power which no one can deny. I've seen many reports that 6" achro comes close to both 8" SCT and 8" Newt (of course with certain limitations).
I know it's strength is wide field views but I've heard people used them as a high power instrument for planetary observations as well. That's of course again those people who like me are perfectly fine with the CO.
What I'm also interested to know is how good the quality of this achro is. How durable is the focuser? What material is used for the lens cell - is it cheap pot metal or a little better aluminum? Both of these are not good for constant collimation screw adjustments and I wonder how the lens cell holds up in this respect.
