Seeing and Transparency was excellent this evening. I spent about an hour cooling my OTA with a CAT Cooler fan. The GRS is turning light orange. The GRS is...
Does anyone (including any dealers here) know the threading on the back of the new Celestron 11" and 14" Edge HD? The old C11 and C14 were thread compatible...
My "research" leads me to conculde that back focus (at least for Celestron, in my case the C11 EdgeHD) is defined as the distance from the last camera-side...
Hi, No -- the 5.25" number is from the rear-most surface of the SCT back. If you measure from the 3.29" back it is another half inch: 5.75". Cheers, Andre...
Hello Andre: I think we are saying the same thing...?? Your 5.25" is "from the rear-most surface of the SCT back" (top of the 3.29" threads?) and I take that...
No, the top of the 3.29" threads is not the same thing as the rear-most surface of the sct back. The sct back adapter adds another half inch. If this isn't...
Seeing and excellent this evening. I had to cut my session short because clouds rolled in. The SEB looks quiet here. An SED can be seen and the EZ looks very...
Sorry if these have been asked a ton before. One question is mirror flop. I was wondering how others have handled this issue. So far I have tried thicker...
Regarding the grease: don't give up on this until you try replacing the existing baffle grease with Dow High Vacuum Silicone grease. In many cases, it makes...
Ok I will look for that grease and give it a try. As for how I know its the mirror flop I have done a few things. What was happening was when imaging my...
... Given the original image seems to have more detail and better quality, one has to ask: Why would you want to add a tele-extender? -Noel _____ From:...
I hope the dow corning works out for you. I tried it and ended up removing it and going back to Slick 50. Didn't do a thing. Maybe I should have really...
Greg, I used the Dow Grease on my C11 to help alleviate a severe focus shift problem and it removed about 90% of the focus shift. What I did was to use a fair...
Hi Noel, If the seeing (or the lens' aberration/diffraction limits) warrants a finer image scale than is available without a tele-extender. Basically that's...
... Makes sense. Thanks for the detail. Did you evaluate whether the Telextender curves the field any? The Hyperstar 3 on a C11 curves the corners of an...
I was cloudy this afternoon but it cleared during early evening. I wasn't able to cool my OTA so my images are a bit spotty at times. The GRS can be seen in...
It was mostly cloudy today. I had a 15 minute break in the clouds. I was able to cool my OTA today for an hour so seeing was excellent! But transparency was...

Does anyone know, is the Dec gear supposed to be limited to 100deg of travel by the drive? I ran into an issue during a training session with Maxpoint and the...
The condition you found the dec drive in is, sadly, common. I found it necessary with my LX200 to disassemble both axes, clean out the old grease (which was...
Even the C14 Hyperstar has geometric distortion that would show up very easily were you to shoot architectural stuff. For astro the main nuisance is that if...
Where should the grease be on the Dec drive? I assume on the worm gear and spoked gear (?sproket). It seems there is a lot of grease all over the main gear....

The grease should be on the entire worm, and the edge of the worm gear. It doesn't need to be all over everything, even though that's kind of how Meade seems...
To fill in the details- the scope won't go "over the top" past 90 degrees dec/alt (or wherever the computer thinks that is, so as Chris said it depends on...
