  1. Is there a chart or some way to figure out which objects you should be able to see given the Bortle number of your location and the aperture of your telescope?

     

    For instance, I'm at Bortle 8-9 and have an 8" dob.  I *think* I located and saw M10 the other night (hunting around with an angle gauge on the OTA), but it looked like a barely visible circular fuzzy dust smudge. I wasn't able to see it at all in the finder scope (8x50 RACI). I was very excited thinking I had found it after 10-15 minutes of hunting, but also surprised at how difficult it was to see.

     

    Thanks!
