Quote:BT100's with their shorter FL that I think is in the F5+ range vs F6+ range of the BT80's.

Quote:I know that this thread has not seen activity for a year-and-a-half, but as I just sprung for a pair of BT-80/45's that Kevin had on clearance (messed up paint job), I am interested in eye piece choices for this model. Many of the choices listed in this thread for WF viewing were suggestions to try, but the results were not reported. Also, some EP suggestions were made in another review on the BT-80/45. I am interested in hearing from folks with this binoscope (or the GT-80/45) as to what you have found to work, and which are your favorite choices for various qualities (e.g., sharpness, contrast, fov, etc). Thanks,--Tad(now spending my FY2010 astro budget)

Quote: If you don't want to spend the big bucks on a pair of 24mm Panoptics the Baader Planetarium - 24mm Hyperion Modular Eyepiece with 68° AFOV and 20mm eye relief should be a good low cost choice.
