This scope was back ordered for me but is going to be shipped real soon and was thinking of buying a few Explore Scientific eye pieces for this scope. I have never used any of their eye pieces. The scope comes with a  WO 50 mm uniguide scope and field flattener. Any suggestions of ES eye pieces to would work well with this scope?

 

Going to use this scope with my new Explore Scientific EXOS2-GT Equatorial Mount with PMC-Eight GoTo System soon and was excited about getting this scope. I wanted to get a bigger WO scope but money wasn't in the works right now. Any suggestions would be appreciated

I have had this basic set of mounted 1 1/4" eyepieces for over 30 years now and would never think of selling them. I'd even sell all my 2" eyepieces first.''

The  Explore Scientific 92* eyepieces are hig contrast sharp units. 17mm and 12mm. Unfortunately they are expensive. Im loving the 17mm for a fairly wide view in a shorter focal length scope and nice eye relief too.  I've enjoyed using for years a meade 14mm uwa (the older japan one not the newer series) and these can be had in the classifieds for about $175. The  Pentax XL series is very good also.

For many, the 68° line hits a nice spot for price/performance. A minimum selection in what ever you choose IMHO would be a High, Medium and Low. Target around 160 at the high end, 80 for mid (and a comfortable 1mm exit pupil) and 30-35 for the low.
Good Luck!
