I couldnt find a more appropriate forum to post this in than here, so here goes.

I need a portable scope as my location (long island, NY) is severely light polluted... Im about 25miles from the center of NYC! I already have a 10" dob and its a bit too heavy for me, so Im looking for a more portable CAT scope with at least a moderate aperture. The two scopes Ive been looking at are the Nexstar 6se and the ETX 125 PE UHTC. How does the image quality differ between these two scopes? I want an all-arounder that does well with the moon, planets as well as some of the brighter deep space objects (M13 Globular, M42 Orion and M31 Andromeda Galaxy, etc.) as well as a scope for birding and terrestrial photography. (Night time photography afocally is also a possibility of the moon and planets with a point and shoot digical camera. Maybe deep space later on with the deep sky imager.) I've heard the ETX might produce sharper, more contrasty views but not sure about that, and I dont know if the extra 0.9" of aperture the nexstar 6se provides much of a difference compared to the etx. Thanks for any help!
