Skywatcher 5.1" parabolic reflector for DSO? Hi, I've been scanning the night skies with my trusted 12 X 50 binoculars up until now and want to move onto a reflector for deep-space objects. Budget and portability have pointed me towards the below scope and i wondered whether any other members have any experience with this model or given the specification can comment on its suitability. Unfortunately, i don't have the best of viewing conditions (city light pollution!), but with my binoculars i've been able to make out M13, M31, M34, M92, and others. Skywatcher Explorer 130P 5.1" Parabolic Newtonian Reflector f/650 (f/5) Magnification: x26 & x65 Eyepieces (1.25"): 10mm & 25mm Full spec here: http://www.skywatchertelescope.net/13065.html Thanks in advance for all your help.
