I have been using Siebert's Black Night Binoviewers, 24mm ultras, 12.5 standard eyepieces, barlows, adapters, and the 36mm "Observatory" 2" eyepiece. I've bought all of these gradually over the course of the last year, because of the consistant optical quality and excellent service Harry Siebert delivers. So, unless this last review was some type of joke, I have to ask myself, "what was this guy smoking?"
>Cheaply made out of copper plumbing parts... Err... excuse me... I would like to know when you purchased these. I have never seen Siebert's 2" binoviewer, however the Siebert Optics website indicates these are made from aluminum alloy, not copper. Even has a photo, which suggests a pretty rugged unit. Don Regan's review of these units makes no mention of your problems. FWIW, I have Siebert's Black Nights binoviewer which are very neat and well-made units. I clicked on the link in Excelsis to try and find your name, in case i recognized it, but all it had was initials. Whatever... Bob Bennett, Maple Vly, WA

Mr. Siebert: I once had a truck that was going to be used for a long trip. I brought it to the local garage and asked them to check it over. They charged me over $1,000 for brakes, etc., but said it was ready for a long trip. Five miles down the road a hose burst. When the car was repaired (somewhere different) they pointed out that all of the hoses were old & cracked. When I went back to the garage to ask why they hadn't caught something so obvious, the owner got mad at ME, actually chasing me off the property with him swinging a huge wrench over his head. Your response to criticism reminds me of that garage owner. Like him, his reaction is more important than the original problem. I wouldn't use him ever again, and I won't buy telescope equipment from you. If this is how you take criticism, reviling the critic with ad hominem attacks, I don't want to have anything to do with you.

Wow! I will never buy anything from you, Mr. Siebert. You seem like a very nasty fellow. I agree that it is a bit shady for you to even be posting here about your own products. Even more shady is your character asassination of the people who give your products less than favorable reviews. You have turned me off, I don't like to do business with people like you. -Mark Johanssen >(Revised) 12/28/03 > >Mr. Scope fan keeps updating his bashing of my unit regularly to keep pace with my clarification of his less then truthful statements.

>Being the first to person get this two inch Bino-Viewer, all I can say is ammazing views. The views on the double cluster were out standing, but I'm still lost for words. M13 last night in the 9" APO was like I've never seen before. The flat field of view and seeing M13 with both eyes was WOW!!. Using this bino-viewer I've noticed that M2 and M13 resolved at lower powers than when using a single eyepice. The outer region's of M2 were resolved using the Siebert 32mm Ultra Pluse two inchers at a power of 88x in the 9" APO. At 201x the view was just mind shattering. M13 at high power ( 320x ) was resolved like I've never see in my 30+ years of observing globular clusters. The dark lanes that I've seen before in the resolved core was seen more easily and in more contrast. The chain star that run up through the core to the outer regions, stood out in 3D form. The view of M8 was jaw dropping. Nebulosity regions were seen easily and had more contrast than with a single eyepiece. I only hope that Bino-Viewer #2 that Todd Gross will get to review is as good as mine. > note: Two inch Bino-Viewers are a big step up from 1 1/4" ones, that mainly work great on the planets. These two inch bino-viewers so far have worked flawlessly on everything from Neb's, Open Clusters and Globular Clusters. As soon as the gas gaints are up all night, I'll be getting no sleep at all. I would like to make some remarks to my post above. I do not want anyone to feel that I'm trying to say that 1 1/4" bino-viewers are only good for planetary observing. I have tried my Tele Vue units on deep sky objects, and find that they do good on brighter deep sky objects. But they have only 26mm optics, where as, the Siebert two inch Bino-Viewer unit has 40mm optics. Because of the 40mm optics I see much brighter objects and more sharper images with more contrast, on objects of 8th mag. and fainter. A more indepth review well be posted soon. I've used the two inch unit in a 9"APO, 6"APO, 6" Archromat, 10" SCT, 8" SCT, and a 16" SCT. I only put up this short review to let everyone know how the unit is working so far.

>Outstanding evolutionary step for visual astronomy. The Siebert 2" binoviewer performs exactly as one would hope, providing clear, crisp, bright, pseudo 3D wide field views of the heavens. ---- Hmmm - Methinks that the vote by kkirksea sounds more like an advertisement. Interesting if you click on his voting record and see that he has owned several of Siebert's products, as well as the same scopes Harry uses. Somehow I don't think that Denkmeyer is the one playing dirty tricks here.

>The Siebert 2" Binoviewers present an interesting dilema for me. Although they work O.K. (some problems with eyerelief, merging images, collamation) my biggest problem with the Sieberts was the quality of the fit and finish. It seems strange to put a pair of $500.00 eyepieces that have superb fit and finish into a Binoviewer that looks like it was made in my basement by my 7 year old son with parts he salvaged out of my plumbing supply box. Other than that, I suppose they fill a niche for those how don't really care about pride of ownership, and are willing to put up with their quirks. > Rob Are you sure you can tell the truth. Sounds to me like you should be teaching your 7 year old how to tell the truth.
