Hi Preston, Nah, don't worry about some wrinkles or pinholes. You might see some pinholes when you hold the film up to a bright light source. I have both ...
Hi Everyone! You might want to get up a little early on Feb 2nd. Io's shadow will ingress at 4:15 AM EST and Io itself will transit, ingress starting at 5:28...
Preston, You may have seen this but if not check out this site: http://www.astro-physics.com/index.htm?products/accessories/solar_acc/astrosolar and click on...
... I purchased a Kendrick made Baader solar filter. The leaflet that Baader included with the filter states that wrinkles are not a problem. Some people may...
David, My understanding is, no, it will not be APO. It will have a new lense design and a better glass but will still be an achromat. The new glass is going...
... It cleared up. (Can't figure it out, I seem to have a reverse curse lately.) In a nutshell, the 5k 20mm is VERY nice! David: Yes, I agree it is a very nice...
My understanding is that this scope will use FPL-53 glass which should mean its performance would at least match that of the Synta ED80. I was curious if Vic...
What is an NHNG? Also, I have an AT1010. In addition to the non-retractable dew shield, what is the difference between an AT1010 and a Nighthawk? Are the...
... Steve: "NightHawk" is the common name for this not-so-common scope. The AT1010/NightHawk has gone through several iterations. The older ones have the...
David, I enjoyed your observation report--glad you like your new EP. I've never been successful at seeing either the E or F stars in the Trapezium, but to be...
Kevin Yes, I noticed the grease! I also noted that the chrome barrel is screwed on loose and if you adjust the eye cup with the eyepiece in your hand you have...
I believe from Vic's past postings that at least the early AT1010 scopes used a cemented achromat where the later NH scopes have all used a air spaced...

David; From the current listed specs on the SV web site I suspect that it will have close to APO color correction. It will be the first non- APO I am aware...
The Nighthawk lens - over 3000 of them - use our own proprietary airspaced design which gave us the design freedom to provide a wide, flat field with excellent...
Thanks for reading, Scott. I first saw the E and F stars of the Tarpezium with a 6mm ortho eyepiece, 132x in the SV102ABV. E is much easier because of it's...
Hi Sandy, and group... i have been communicating with preston re SparrowH---- mounts etc...Now, I am not a Luddite, but I am behind the curve on digitally...
The first prototype used a very convetional lens design using FPL53. Some companies refer to any telescope using low dispersion glass as an apo. Samples I have...
Thanks for the reply, Jim. I think you also need to use the sharpest, best eyepieces in your arsenal. You used Radians, I used U.O.Orthos (initially) and then...
... Thanks for the info, Considering that I'm off work tommmorrow I guess I'll have to set may alarm alitte earlier. Check out jupiter then catch some fish....
Hello All! I think I got it now! Jeff and Vic did give a good description of the differences. I purchased my AT1010 about a year ago, so I think it uses...
On the Stellarvue website it says that the binoviewer focusers are a new Stellarview addition to a binoviewer currently being marketed under a variety of...
Vic; Sorry for the error. Based on some other member's postings I was under the impression that more of the cemented lenses were used. Sounds like they were...
... Yes, alignment, convergence, and focussing are all improved in the Stellarvue binos. Norin makes the binoviewers for Stellarvue, Orion, and Burgess....
Steve, I had one of the original cemented lens AT1002's and it was a very good scope. As Vic said, only 20 or so of those ever reached the public, and these...
