... i just bought one of these. I really wanted a 20mm GSO Plossl, but Owl is no longer carrying this focal length in a Plossl, so i decided to gamble $34, and...
One should always mince one's words in case you have to eat them later! Since the sky is cloudy here I thought I'd try the "tree test" on my Astroscan. Using a...
Bob, I ordered the 42 2" for my Hardin 8" f5 and they accidentally sent me the 30. I sent it back but not before trying it out in my scope. It was less than ...
... I'd like to make a few comments about what's going on here. A 42mm eyepiece in your scope will yield a magnification of 24x and an exit pupil of 8.4mm....
I want to replace the straight through finderscope on my Dob with a right angle finderscope. I can spend USD 150 on a "proper" right angle finderscope or, I...

I don't know how this translates to viewing the moon or planets but I conducted the "tree test" on my Astroscan today. Using a 4mm Plossl and a 2.5x Barlow...

Ah yes, the patio door currents! It was wavy, but during "moments of good seeing" the bark became clear and distinct, enough to make me think it would be the...
... Hedley, As others have said, one choice is the Orion 9 x 50 RACI (right angle correct image--image matches star charts). It's a quality finder for about 75...
The Orion one is fine as an alternative Antares that advertises in the small advertising section of Sky & Telescope offers high quality ones as well for <$100...
I forgot to mention that I prefer 7x50 to 9x50. I like the wider field of view and the 7mm exit pupil makes better use of the available iris openning (Usually...
Geoff, I have no doubt that my 52 year old eyes are a big part of it. I wear glasses, progressive lenses and have moderate astigmatism. I am lucky I can see...
