Quote:A 10mm with a Barlow is one option or you might consider something in the 6-8 mm range as well. I have the 102mm f/9.8 Omni XLT that I have used a 5mm Hyperion with mine a few times but will generally drop back to 6 or an 8mm for sharper views on viewing the planets. A 5mm can come in handy for helping to split close doubles from time to time as well.

Quote:I like the ES 82 degree 6.7mm. The 4.7mm works too but not as sharp.

Quote:IIRC, Bill prefers the Sterling Plossl 12.5-25mm over the TV Plossls because of their wider field. He says the Sterlings below 12.5mm are not as sharp - even on-axis - as the TV Plossls.

Quote:FWIW I find it easy to tease out on-axis differences between eyepieces, especially with the APO...you just have to know where to look on a target and for what features that are most susceptible to minor performance differences on-axis.
Quote:It's all a balance of things and one attribute for me never trumps others. So for the overall gestalt I feel the Sterlings do a better job overall than the TVs. They also have killer good transmission and wonderfully uniform backgrounds with no lightening near the field stop.
Quote:I usually keep the 25mm, 17mm, and 12.5mm in the Baader Turret on my TSA-102. Those three and a 7mm Pentax SMC Ortho or a 6mm ZAO-II in the 4th slot makes a great workhorse turret, and nice in that the wider AFOV of the Sterlings make them feel like mini-wide fields
Quote:Just love their convenience. Also, they are killer sharp with that Baader 2.2x Barlow that is part of the BCO set. Was out this morning with that arrangement on my TSA observing Orion and the Perseus Double and Jupiter, and the Moon last evening - Nirvana
