Quote:I just bought 9mm and 12.5 UO Abbes for use as planetary eyepieces. The moon at 300 was razor sharp and they got a good a view of Jupiter...eye releif with the 9mm seemed find to me.

“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

Quote:Heck - I'd never get any observing done with that much choice. I'd be constantly swapping to get a better view and dithering over which was going to work best. How do you ever choose what you going to use with that lot ?
Quote:I [...] consider the eye relief advantage of the volcano top to be a myth. On both styles the eye lens is right at the top of the black housing and unless you have a very small eye socket you eye can get just as close with either one without bumping into the housing.
Quote:The reason why people find the volcano-tops more comfortable is that... on the VTs one's eyelashes don't brush the eyepiece housing quite so much.
