Quote:I was out with my 102mm f/9.8 refractor 2 nights ago.But I was trying to have a shoot out between my Pentax XW and Ex Sci and Baader Ortho 'similars' and outside of the eye relief of the Pentax, and the different FOVs, I couldn't really tell the difference in VISUAL object comparison. I was using Jupiter, M3, M42, and the double cluster. I want to sell one or the other, but can't decide. Seems the the Pentax focuses slightly easier, but has that overly huge eye relief, difficult eye placement and no eye cup, (at least for me personally) I have a lot of neighbors lights and so that's a problem. Right now I just have this refractor and a C14.Seems like the ES shows a touch more false color, but I can't be sure of that, especially with my bad eyes. Any thoughts? They are:ES 4.7 vs Pentax XW 5mmES 6.7 vs Pentax XW 7mmES 9mm 100 degree vs Pentax 10mm vs Baader 10mmI won't get rid of the ES 9mm 100 degree.How do you 'test' eyepieces?Thanksbob

Quote:differences between eyepieces. In the end, it's best to confirm what you see during the day with astro objects and see if you like the way the eyepieces frame certain objects..

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
