Thomas I would like to add one more comment to our discussion about “Outgassing” on your mirror. I Iooked at the picture of your mirror again and noticed something peculiar. It looks like this

Thomas I left myself some wiggle room when expressing my “opinion” which is always prudent on the groups for many reasons. Now that being said I will say this. I own two Crestron Scopes. One is 8

Gary, Thanks for your reply. I am not sure about the term "outgassing." Maybe there is a more precise term. On the Cloudy Nights Cats and Casses forum there are numerous threads and posts about

Thomas I (Personally) have never heard anyone mention or use the term “Outgassing” with regards to the grease used on SCTs. In my (Personal) experience, and I have had a considerable amount of

I am just assembling information at this point on possible outgassing in my one and a half year old C14 Edge. I have some "haze" on the primary mirror. I am not sure if it is water residue or

Hi Don, I see the surface of the original gasket has a little friction to the glass and must have the problem again soon or later. I bought the scope 4+ years ago and removed the corrector plate

Hi Yasushi, We had the same problem on the C14 Edge at the Mauna Kea VIS here in Hawaii. I talked to Dean at Starizona and he said the secondary notch may not be at the three o'clock position as some

Hi, Seems like the alignment of corrector plate to secondary mirror is critical to the optical performance of the tube, and how can I tell the correct alignment for EdgeHD1400? Two weeks ago when I

very nice! You are in the same league as Christopher Go. Stan

That should have been shocked, shocked to find mirror flop with stock pole dancing C14.

I have a C14 and the mirror flop is almost imperceptible. Certainly no loss of collimation or quality of the stars. I can do a closed loop slew across the Meridian, my rotator rotates, and I find the

I am shocked, shocked to find mirror flop on the C14.

Actually, I am not sure about the human error part of it now. I don't think I check the direction of the final mirror focusing. It's entirely possible it was counterclockwise and the mirror does have

I feel your frustration. I too am experiencing a problem that I cannot seem to get my head around. After shutting my Observatory down for better then six months and then start imaging again I just

To clarify: I'm using Celestron x0.7 reducer - very sturdy, no play. Moonlite is a Crayford-style (extremely well-built) and used from mid-point after mirror-focus. I never touch mirror focusing after

Are you saying you have a Moonlight focuser on the rear, a crayford style focuser? Something does not sound right here. Once the mirror is locked down you cannot focuse it (tweak) it. Locked is
