Hi Ian, I use exactly the same system for about 3 yrs now. and am able to get the optimum focus point using the reducer. I have the same trouble with focus shift and meridian flip any solution other

I have my 14" EdgeHD for over 2 years now. It originally had a problem with not holding it's collimation and had to be sent back to "C" where they "span" it - much better after that. I use it mostly

Outstanding, Christian. What is the field of view in your images? -Charlie Lasnier

Hi Christian, The Cassagrain is of a classical design originally made by AE astronomical equipment (UK) on it's original gem. Bought it 2nd hand a couple of years ago for planetary imaging which I

Thanks Kevin :-) My observing site is 1500 m high. The seeing was relatively good, although not perfect. Video cameras and processing software are doing now a very good job. Best regards Christian

Thanks a lot Eric :-) Is it a home-made Cassegrain ? Best regards Christian

Your amazing images make me feel as though I am in orbit around the moon, Christian. Can you describe the seeing conditions at your imaging site? Clear skies, Kevin Dixon www.magnificentheavens.com

Dear Christian, I always look forward to your solar and lunar images. They simply takes one's breath away. Next summer I'll set up my 12" cass and have a go. I use my C14 edge for ongoing photometry

Dear All, At last, I've found some time to process a part of the moon images taken last August 6 with the C14 and the Basler 1920-155 camera : Clavius :

Also on my corrector I get no moisture on either the inside or outside because the corrector heated a very small amount above ambient which insures no dew will form. The DIY circuit I posted earlier

"Are you inserting the camera into an external focuser or directly into the rear of the SCT?" Direct. Don't use an external focuser or anything else (e.g. no filter wheel). It is a pre-HD OTA with no

Are you inserting the camera into an external focuser or directly into the rear of the SCT?

P.S. I suppose the explanation for inside dew (before outside) is that the relative humidity is higher at the start of the night and is captured by closing the tube (e.g. insertion of the camera).

Unlike the open frame Crayford focusers, my focuser is completely sealed with the flexible bellows and mounting O-ring between the telescope and focuser. I had a customer in Florida tell me that my

Dew inside the tube is not uncommon. My C14 will often start dewing on the inside side of the corrector before it starts on the outside, which is difficult to explain. But I haven't had the primary

Here is a DIY circuit that uses the minimum heat so no dew or frost will form. http://www.clementfocuser.com/images/Temperature_Control_Print.pdf
