Equipment - backyard- observation place
observation place
My observing place is in my garden with a bortle 6 - 7 sky. If you observe from the city, unfortunately you must accept restrictions ;-)....a consolation, I have good observing conditions in the zenith...
Celestron C14
Since decades, the C14 is manufactured by Celestron. Meanwhile it has a very good reputation as a powerful big optical system. The Schmidt-Cassegrain has an aluminium tube, therefore very compact and not too heavy. 14" aperture (356 mm) collect a lot of light, just right for high-resolution lucky imaging. If you see very good astro photos made by a big SC system, you will find out that most of them has been made by a Celestron C14. It is also used in many observatories because this high performance optical system is still compact and leaves enough space in a standard dome or shelter.
Astro Physics (CCDT67) 0.67x Focal Reducer + ASI294MC pro
I use the Astro Physics (CCDT67) 0.67x Focal Reducer for astrophotography together with my C14. It is very well suitable for SC telescopes - the focal ratio is improved to f/7.4. The image field is not corrected, only the focal length is reduced. Sensors up to APS-C format can be used. The Astro Physics tele compressor has originally been designed for telescopes with f/9 and slower. My tests have proven a very good suitability for C14 telescope.
