After a few sessions of viewing the easy objects (moon, Jupiter, Saturn, Venus), I thought I should expand my horizons and try for a few "simple" DSO. Things didn't go so well. I am using a 102 Mak on a very basic EQ-1 mount. After some newbie struggles star hopping I have thus far managed to find / view the open "easy" (?) open clusters M13 and M22. Both came out as faint blurry patches, far cries from what I might have (naively?) been hoping for. I realize the setup is basic and I am willing to make an investment to so that I can further enjoy this hobby, but I'm a bit at a loss of what is limiting the viewing right now -- and guessing could be a very expensive experiment!
1) Light pollution: Viewing from what I think are roughly Bortle 5 skies (outer suburbs of Madison, WI), although I do have some direct street lights to deal with. I have installed a dew/light shield to block direct light into the scope but didn't notice much of a difference. I read that a CCD/camera might help overcome this, but I'm not sure that this is the limiting factor.
2) Resolving power: With only a 4" scope, should I expect more than a fuzzy blob? Yet I would think that I could resolve at least a FEW bright stars out of the blur.
3) Light collection: I realize that aperture gets me more light collection as well, but a simple CCD would presumably also help with this with via longer exposures.
Advice from some seasoned experts as to what I should be expecting and the most effective "upgrade" path would be useful. Note that I am well aware that moving to darker skies would be ideal, but given 3 young kids I am looking for a setup that might be able to give acceptable results for simple DSO in typical "suburban" settings so I can actually USE my setup on a regular basis.
Thanks so much for your advice!
