Hello Group, I've given up trying to do searches from Yahoo for info on this: Yahoo either returns info which doesn't even relate to my search parameter or...

Thanks again to everyone for your kind words. I've been an imager for a total of 5 months and a visual observer for 38 years. Imaging is fun and I plan to...
Hello, Thank you all for your interest and support. I have a call to a few laser engraves and expect to hear from them in the next couple of days. I have...
Hi Group, First a question - probably for Markus as much as anyone else As you know I've mounted my 152 LW on a G11. The G11 came with a 21 pound (9.5kg)...
... What do you mean? :-) \ Actually if you can push in one direction and it doesn't stop, does that if you pull in the opposite direction it is harder....
... Hi Thomas, No no no, that was never the intent. They are, and will be, sold by Particle Wave Technology. I hate selling things. I just buy them. All...
Hi Harvey, The DDCAPs are already machined and ready for anodizing. To make the groove deeper may pose a problem (or at least added cost). I will talk to my...
... Hello Ray, I have a TMB 152 CNC on a G-11. I use *two* 21-lb counterweights in my setup. The weights are about half-way down the shaft. I should think that...
7 mm and 9 mm have been available only as new styled parfocal modells Markus ... From: "W. Gondella" <strehl985@...> To: <tmboptical@yahoogroups.com> ...
... I'd say that is just what I have. having said that what do you think of Louis's comment "I should think that the closer the weights are to the mount's...
What is the price of the TMB CNC tube 130mm refractor? I thought that I heard (or read) that they were going up. On Markus's site it is listed as $5390.00 ...
... counterbalance > the scope? ?< Ray Probably not. I had to ask our good friend Rob Dalby to make me a second counterweight to balance my Mak, guide scope...
... Louis is eluding to stability due to the second moment versus first moment. First moment is just the force x distance, or simply balancing the RA axis....
Hello. Desire to buy a 130 TMB F:6 but before desire indicates to me if its quality is parallel to the price. Other that I like is TEC 140 APO. As will be...
Mario, That is a good question. The TEC shows a very high strehl of 0.99. Is this all that really matters? It'll be nice to hear some comparison notes on the...
... One has to ask is that strehl measurement made with a certified Zygo interferometer and how many data points are used. Also, is the test done with the...
... Hi Tim Please help me sort out interferometry. Someone in-the-know needs to post a treatise on interferometry on Cloudy Nights. Hopefully it wont land in...
Hi Mike, It turns out that there are two ways to utilize the fringe data to arrive at the surface profile. Programs like QuickFringe trace fringe centers, and...
... Thanks Kurt, that was very interesting. The repeatability of producing near identical set of fringes with proper thermal handling and proper optical...
... proper ... those fringes ... Actually, no. The software solution is constrained to fitting the polynomials to the data points, and reporting the results....
... Thanks for the update, Kurt. My point is mostly about the inclusion or exclusion of abberations like astigmatism, coma, tilt, etc. If you present fantastic...
