I just got new eye glasses this week and got anti-reflection coatings to help reduce glare and eye strain since I spend so much time in an office at a...
I'm interested to hear from people using the *standard losmandy tripod* on the G11 what kind of damping time they have with their refractors when they give...
... Probably the best test is not damping time but deflection. Tie a string to the end of the focuser, attach a weight and set it swinging. Notice what the...
Greg; With my TE$C 140 damping time is in the very short category, well under 1/4 second by my estimate even at high power. It makes the combo excellent to...
I intend to do that since I have three setups (two EQ heads, three tripods) that would be interesting to measure. However, I'm just trying to get a rough idea...
Basically you seem to be saying the damping time is too fast to measure. (& I thought you were a Stellarvue user or did I get that wrong or ya got both?)...
My results are using a G11 on a permanent LeSeur pier with TEC140. I know it's not exactly what you're asking for. I used to focus with the camera attached,...
... I ... measured ... 3 to 4 seconds is about right for most mounts. This is the time it takes for the image to stop moving and become diffraction limited. ...
My curiosity on this topic is piqued by the extraordinary solidity of the G11/Berlbach/FS128. My "normal reference" is the C14. As Roland suggests, damping...
Greg, since this is such an important test, just go ahead and drive the spikes into the wood floor in the house ;-) That's what I did with my 200lbs...
Wood is an excellent damping agent and should reduce the time that it takes to settle down. Metal always has more of a ringing quality to it and may vibrate a...
Well I guess this will be interesting for all of us. I had hoped to do it with a PWT as well but no reason not to get started on the three tripods that I...
I am going to sell on the 'mart a four inch Tak FS128 focuser with the microfocus 10:1 adapter and the Camera Angle Adjuster. I plan to sell as a unit because...
... I had my Intes 6" Mak-Cass a G11. There was no damping time - really. I have back trouble and used to support myself by having one hand on the tripod. I...
Greg; I have TEC, SV and Synta refractors. The TEC is the heaviest and longest tube assembly. Roland could well be correct about damping time but with the 140...
I often have a very heavy homemade 130 f/9.25 on a G-11 and have always considered it to be rock solid. Certainly never any noticeable issue with visual...
I think so: computer-based star measurements are accurate to approximately 1/10 a pixel. For my setup, this represents theoretical precision of about 0.14...
All the posts seem relatively sensible. I used a large number of configurations where a thwack to the tube shows a 1.5 to 3 second dampening time as shown by...
Dunno, I'm afraid I'm not as informed as I should be about makes and models, without backup from the web sites I'm pretty useless. I find the idea of a 5.5...
Greg, To widen the market and sell more telescopes, vendors are starting to break telescopes into significant "specialties." Do you now own a telescope...
OHHHHHH those planets. For some reason I was thinking of planetary NEBULAE. Because you REALLY have to HUNT for those. It didn't even occur to me that one...
... Greg: Whatever he calls it, it's a very nicely priced and well made refractor line?. My 80mm P.H. had well collimated, sharp optics and at high powers...
Well Don called it a planetary hunter. To me that means chasing after exploded stars. Since the bright ones like m86 are pretty easy it made me think of all...
... Okey-dokey, then. I would think that means we would drop the term "Super-Planetary" from certain higher end refractors and eyepieces, Yes? Clear Skies, ...
