This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K).
The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention.
For a precise collimation, i use the CATSEYE XL & XLKP kit.
This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.

I have a GSO 6" f/4 Astrograph, and there's always been this issue with elongated stars on one edge. I've checked collimation and it is perfect, but for the elongation on one corner. Could someone please throw some light on what's happening
Right now i am imaging with a Star Adventurer and a 300mm telelens on a dslr.
I am planning to upgrade to the eq6-r pro and currently i am searching for a telescope. i want to take pictures of nebulae, galaxies and planets.
My first idea was to get the Skywatcher 250/1200, then i read that it is too big for the eq6, i was recommended a shorter tube like the orion 10" at f/3.9 or a SCT, due to my budget i can't get higher than the edgeHD 8 unfortunately.
what would you recommend? i am also open for different suggestions, thank you :)
Hi! I am very new to SGL (just signed up a couple of mins earlier) and to astronomy as well, though I have been facinated with celestial bodies since I can remember. I recently purchased a Celestron Powerseeker 127EQ but now I’m having troubles using it and I can’t seem to see anything through it. I also have a Celestron collimating eyepiece but I still can’t seem to make it work. Anyone here who has experience with the same scope? Would appreciate if we could chat a bit as I would be really interested in your experience and how you ultimately made it work!
I recently tried imaging M7 with my 6" f/4 Newtonian. I had earlier commimated it with a Cheshire and Howie Glatter and was sure of the collimation. However, when I imaged using my DSLR with the coma corrector installed, I get focused stars off centre and not on the optical axis. Anyone experience anything similar before? What could this be? Tilt in the optical train? The focuser was drawn out only about 5mm to reach focus along with a 50mm extension tube. Any suggestion is welcome.
