Good question, but my guess is that the adapter for SCT threads was originally included as an accessory, since so many other accessories use SCT threads, but...
Well that's one way to prevent dew, if you don't mind generating a lot of bad seeing from all that heat. A simple dew shield will go a long way towards...

I think for bad seeing, dew wins out over heat every time! <g> A dew shield only postpones the inevitable, heat is the permanent solution. I use Kendrick...
Excellent viewing yesterday! It started with the moon around 6:30 EST (11:30 UT). The seeing was average and hurt a bit by my having to sight over our roof...
Dave, The next time you go to use the C14, let me know if the 2" diagonal can be removed by itself with a small retaining ring or it unscrews from the 3"...

As a youngster I remember the Scientific American ads of the 50s and 60s showing the Questar. I longed for one, but couldn't afford it. Then in 1999 I...
Thanks, but I think I am all set. Celestron got back to me with a part number (#51413), it is only $35 + $5 S/H. I believe the original diagonal unscrews, it...

Hi Jack, That rocks! I once owned a 1982 standard Questar myself! I happened to be lucky enough to own it at the same time as I owned a Meade ETX 90 E/C - ...
Dave, That's good to hear, problem solved. When you unscrew the diagonal, before you add the 2" visual back, look at the size of the rear port opening. Compare...
I did the experiment as I have both scopes on the same mount: http://home.att.net/~dpersyk/new.htm Due to the greatly differing focal lengths of the two...
A couple of comments. (1) The stars seem as tight in the C11 as in the refractor. (2) aesthetically the refractor image is more "pleasing" because of the wider...
Hi Greg, Thanks for the inputs. I appreciate inputs on what others see in my images – usually something different than what I see! I should have stated my...
Hi Greg, Are you referring to the fact that my ETX kept up nicely with my Questar? If so, and you'd like more details about my observations, just let me know! ...

6mm is pushing the limit, and winter skies are usually not very steady (note the blatant twinkling of the stars on most clear winter nights). You need a good...

The 6mm gives 338+ power. If you can't get get sharp focus it's because the seeing won't support that great a power. In fact, you'll seldom get to use that...
Right. I have a C8 here in Detroit where seeing is at best average and I can always get a sharp image with the 12mm, many times get a sharp image with the 9mm,...
I too have an C8 Celestron. My highest power eyepiece is a 9mm Nagler. I had thought about getting a 5-6mm for planets but I don't feel I could justify the...
