Every week I do something new to reduce light pollution. Eyes on the Sky is at 650,000+ views so far; more views = more awareness. Please consider sharing with others.
"Considered as a collector of rare and precious things, the amateur astronomer has a great advantage over amateurs in other fields ... the amateur astronomer has access at all times to the original objects of his study; the masterworks of the heavens belong to him as much as to the great observatories of the world. And there is no privilege like that of being allowed to stand in the presence of the original." --Robert Burnham Jr, Burnham's Celestial Handbook

The rule of telescope features: aperture; equatorial tracking; or low cost. Pick any two.
Quote:Pasiukov - that's a good point I neglected to consider for my reflectors. When I read your post, I remembered that using a 32mm Plossl on my little Celestron Firstscope (a 76mm f/4) produces a black spot to some degree. So I'll have to check on my 10" Dob and see what happens.Fortunately my refractors won't have that issue.

"your signature is too long. Please use the back button to edit your signature" A scourge of equipment unpopular to most, but fun for me!
Quote:I just wanted to say thanks for this review! I picked up this eyepiece during the last Surplus Shed sale. I was eager to try it out in my telescopes. Last night after imaging I dropped it into the focuser of my 4.5" and was amazed! The eyepiece performed quite well. The views of the Orion Nebula were among the best I've ever seen through that telescope. The only problem was that bright objects like Jupiter overwhelmed the eyepiece off axis. My solution: stick to dimmer objects.This eyepiece is one you use for wide field views, not planets. It works great and I am glad I bought it.obin

Quote:Quote:Does this eyepiece have a field stop?Thanks, Hi Chuck, No I don't believe it has a field stop. When I had one of these a little while back, it was barrel limited. It also seemed like a 50* AFOV in the unit I had, not the claimed "around 60*". I was however, impressed with the small size and light weight of the unit.

Quote:I just checked the Surplus Shed pictures of this and it doesn't look like mine. The pics at Surplus Shed show a flat top and eyelens is barely recessed. Mine has about 3/4 " of tube above eyelens.
Think I'll be calling them tomorrow and probably sending this back.
Bunch of glue on the lens too around the edge.
Just called them and they said sometimes they change the housing and a lot of people preferred the recessed eyelens because of the long eye relief.
They said to try it out and if I don't like it, I can return it.
At least I can give it a whirl before shipping back.
