Quote:Did you alternate back and forth over a period of time? Or at least once go back to the earlier, poorer performing eyepieces, so as to verify it was more than merely an improvement in dark adaptation?

Excellent review by BillP
Quote: ... I did spend nearly an hour on the Horsehead and the five eyepieces. For me, that is an enormous investment of time on any object that is not a planet or the Moon. I didn't start observing the Horsehead until about 10:45 pm, so my eyes had been dark adapting for over four hours. Also, over the course of my observations of the Horsehead, the sky was consistently transparent. And for what it's worth, at the beginning of each observation with each new eyepiece, I would get my bearings by going back to Zeta Orionis (my Dob does not track). Even through an O-III filter, I'm sure this reset my eyes to an adequate base-line level of dark adaptation. Then, before I started viewing the Horsehead again with each eyepiece, I put the Dark Apparel hood back over my head to help my eyes dark adapt better and to shield them from ambient light.

Quote:I've come close to buying a used 2" filter wheel. But I never do because I remember I'd have to bump up the magnification with a Barlow or Barlow lens cell in order to come to focus in my Dobs. What's the point of using a low-power wide-field eyepiece if you have to double the magnification in order to use it? Then it's no longer a low-power wide-field (TFOV). I might as well stick to 1.25" eyepieces in a 1.25"-filter wheel.Mike

Quote:Well, just a side bar question if you don't mind. I have a pair of 26mm SP by Meade that I use in a BV. Do you think I could see much of a difference with a pair of the Sterling 25mm?If so I could sell the 26 and buy the SPThanks'Bob
Quote:Would be interesting to see the Sterling vs a Zeiss 25mm microscope eyepiece! Last time I compared the Zeiss to a Panoptic on M42 in urban viewing conditions, it just blew the Pan away, detailed nebulosity etched in the sky.
