Just wondering if any of the folks here are missing responses to their ads. One gentleman contacted me that he'd sent me two messages that I never received. I posted a note on my classified that it might be better to pm me, and another fellow did-telling me that some of his messages weren't getting through either. Anyone else, or anyone know anything about this?

Hey all,
I'm looking for a recommendation. I've been using 7x50's on an HD-F2 mount for casual sky scans, but thought a smaller exit pupil might be beneficial. Can anyone point me to an inexpensive but decent set of 10x50's for nighttime use? For that matter, does the move to a 5 mm exit pupil really offer any advantages, or should I just stand pat? Thanks for any help you can offer!

Has anyone had an opportunity to compare the 13 mm Ethos to the 17 mm Nagler? I'm thinking of trading my 17 for the Ethos, to be used in a 14" f/4.7 reflector, and an 8" f/6 reflector. The Ethos will be a sweet spot for both scopes and the field of view will be the same. Specifically, I'd like to know if the Ethos will be as sharp as the 17, and if there are any eye relief issues, as well as anything else you may have noticed! Thanks in advance for any insights you can offer!

Hoping to provoke some discussion, and hear about others experiences with the Planetary Series of eyepieces. Some time back I picked up a 9 mm Burgess TMB here on the Mart. Found that my observations confirmed what I had heard from others--nice sharp ep, comfortable with good eyerelief, reasonably good contrast--a nice performer at a nice price! It did have the noted field curvature and reflection issues others have noted, and since it was so close to my Pentax 10.5, I ended up selling it. It was branded "Burgess/TMB". Recently I picked up a 5 mm and 4 mm for a short focus ED refractor which were branded "TMB" only. Rather than the chrome barrel they have a black anodized barrel, not tapered, but with a recessed ring for the set screw in the diagonal. The specs list them as 10 and 12 mm eyerelief respectively, whereas the "Burgess" branded ones are listed as 16 mm relief across the line. Has anyone had experience comparing the "Burgess/TMB" line to the "TMB" line? I'm finding that I'm really liking the TMB brand, more than I remember liking the Burgess line. The reflection issue seems to be better controlled, and the field is quite sharp, almost to the edge. I haven't taken them apart to see if the retaining ring is the improved one, but the images sure are satisfying. Does anyone know the differences between the two lines, if there are any? Thanks for any thoughts you might have based on your own experiences!

Perhaps didn't say this as clearly as I could, try again!Burgess offers a "Burgess/TMB" Planetary Series ep: 9-2.5 mm, 16 mm eyerelief across the line. This version comes with a chrome barrel. It appears very similar to a model taht Teton Telescopes offers. Word is that an improved version with anodized, tapered black barrel will be available soon. Another distributor is currently offering a Planetary Series simply marked "TMB", with varying eyereliefs listed, and a black anodized barrel with an undercut for the set screw. Does anyone know:
1. is this the same optical package in a new suit?, or
2. Is this the promised updated optical package?
Thanks for any info you may have!

Does anyone have contact info for Daniel? Apparently he's not a member here. Saw his planetary ep review and realized he must have been using a barlow to achieve planetary magnifications with the ep's he was reviewing. Just wondering what barlow he felt didn't take anything away from the image with the fine ep's he was reviewing. Thanks for any help!

How 'bout:
*Tinytown
*Santa Claus conquers the Martians
*Killer Shrews
just for starters?

IF a refractor's your game, you have your choice of low end achros, high end apos, and some nice affordable ed's in the mid range of quality. But what IF reflectors are your game, what choices do you have between the entry level stuff and thhe high zoot stuff (Zambuto, Royce, et. al,)? Suppose I wanted to sell my Orion XT-8 and my 14" T-Scope, and with the proceeds buy something nice in the midrange of quality? Suppose I wanted a nice 10" somewhere between entry and Zambuto?
Question 1. Is a fairly excellent mirror in the 10" range going to seem satisfying after the 14"? Anybody made that trade-off and lived to tell the tale? I do have some nice dark skies to work with.
Question 2. With Discovery/Orion/Meade on the one hand, and Starmaster/Portaball/Teleport on the other, is there ANYONE who makes a quality mirror in that space in between? Thanks for any thoughts you may have to offer!

Bought a 14" f/4.7 T-Scope about three years ago. Wanted to find as much aperture as I could in as portable package as I could get, along with good optics. Certainly haven't been disappointed in aperture, weight or performance. In fact, I've been very pleasantly surprised by the Obsidian Optics mirror. I'm no star-testing expert by a long shot, but I'd guesstimate the final wavefront at ep to be 1/7 or better. Find myself wondering if there are other T-Scope owners out there who have been as satisfied with their scopes as I am. Also, whether other owners have found any useful upgrades to the packages they purchased, especially concerning counter weight systems, as mine sometimes gets overloaded with binoviewers. I DON'T want to start an unpleasant thread concerning delivery times, as we all know they are long with this company, and I had to wait a long time for mine. Just looking for other's thoughts on performance and upgrades.

Allright, I've got a question. About three or four years ago I picked up a set of chinese bv's. You know, the ones supplied by Orion, SV, WO, and others. There not bad actually, in fact, compared to single eye...they're great! In scopes eight inches and under they privide wonderful views of the planets and moon. In my 14", the brighter deep sky objects take on that same three dimensional aspect I've seen on the planets. Always able to see more detail with two eyes, so for me, there's no going back.
Here's the question. I got into to binoviewing for less than two hundred bucks. What would I gain by going for one of the premium units? If I kick up the dough for Televue or Denk, what do I get that I don't got now? Interested in any comments!
