hi folks, I wanna proudly present my brand new toy: it is a double refractor - a so called "binoptic" system. its specifications are: 2 pieces of 5" f/6 TMB...
Dietmar, Please, please, please do not post pictures like this. It's simply not fair on the rest of us struggling to afford a single 4" TMB whilst you have two...
... Hi Larry, I think what happened is some of the 175 rings were drilled with only 3 hole pattern at 3.2" spacing. The AP rings use 5 hole pattern with 3.2"...
you and everyboday can buy this super Binoculars via APM-Telescopes ( we hold the exclusiv for the US market ) and so via our new Dealers Teton, Mark Rieck in...
... Hi Dietmar, Looks cool. This will be a lot of fun for terrestrial or celestial. I will be curious if the 3-D effect of a this Bino is more than the 3D ...
... WG: Tim, you cannot tap a hole with a bottom tap alone. You must begin first with a starter tap (typical tap with taper tip in front--- try saying that...
... WG: Both interesting and curious, Markus. I just finished having a heated discussion about stereo and binocular viewers on another forum; one proponent...
... WG: I would have to say yes, Neil, even though I use each for different things. The PM is very nice, but I usually use it with long f.l. 2" eyepieces...
... Good point Wayne, thanks. At work I have access to a little machine shop. There is a device to hold the tap perpendicular to the piece and keep the tap...
Wayne our brain and eyes are magic. If you use a binoviewer , sun, moon and planets looking brighter and bigger then with single eyepiece view. Here you notice...
... I have tandemed the 4x PM with the TMB 1.8 barlow (imaging) with good results. I've always wondered how two tmb-1.8x would stack, suspect well. Since I...
... With the larger bino that seemed to be the case where was with a pair of smaller ones it doesn't. Perhaps this was due to dark sky versus city skies and...
How is the output optical path done? From Dietmar's picture it looks like three right angle changes. Do you use prisms or mirrors? Is the path large enough...
... Hi, Wayne. Some folks obviously feel that way - and for them there's Jerry Springer. We don't seem to have any trouble getting folks who prefer civility to...
3 high reflection mirrors with about 98% reflection from Protostar are used output is 1.25" regards Markus ... From: erdmanpe To: tmboptical@yahoogroups.com ...
... WG: John, you've confused controversy with incivility. Controversy is essential to DEBATE, ie., an exchange of free information and differing POV's. MY...
... WG: Funny Tim, your comments closely mirror a discussion I just had on another group again. There was a confusion about the true meaning and nature of...
... WG: Thank you Markus for being astute enough to recognize this! ... WG: Funny, I just had a fellow on another group accuse me of being combative or...
Thanks Wayne, Actually powermates were one of many barlows I tried en-route to the TMB, and I'm no expert but in my opinion the powermates are good but the TMB...
... WG: With all this talk about them and Markus having 66 (?) left, now you've got me thinking about picking up a second one for BVing with! Here's a GOOD...
... Wayne, I've found the 1.7x compensator to be excellent and probably use it the more than the 1.25x for planetary observing. I would not want to be without...
...hi guys, I knew you folks would wanna discuss abouzt that issue here...(((-: Diets no testreport yet - rain...clouds...rain....fog... ... are used ... looks...
Hello, a customer of mine from Germany has send me today his first image results , made with the russian TMB 130/6 and our matched big Fieldflattner and STL ...
... WG: Markus, I would say that your FF has some of the best correction I have ever seen, way better than what I've typically seen in the past from others...
the image say to the spikes for the first images he want to test a Robofocus adaption , so he used a crosshair in front of the objective to be able to verify a...
Markus, is this the original TMB field flattener - that has no function as reducer...? AND where do the spikes come from in an unobstructed objective??? ...
