Help please. Last night I purchased an old celestron c8 sct, 2000mm fl, f10 on a fork mount. The mount has no power cable so is pretty useless, but i brought it to defork the ota for planetary imaging and hopefully some small faint dso's. It was a reasonable price. Ive got a heq5 pro mount that i will be mounting it onto. The guy said it needs collimation. I know i need to mount it on a vixen dovetail but the bolt holes dont line up anywhere. Its as if someone has rotated the corrector plate housing around 120 degrees. Would it make a huge difference if i removed the housing screws and put it back so that the bolts line up, keeping the mirror and plate in the same spot on the housing bracket, or would i have to try put everything back separately in different positions and collimate everything from scratch. The picture at the minute doesn't quite get crisp so whatever has been done needs rectifying. Can this even be done by us regular folk? Any thoughts or ideas, instructions? I feel the plate could do with a clean and the primary mirror itself. I just want it as optimum as possible. And can a hyperstar be fitted to these older versions? Im literally starting from scratch with an sct setup. Also what type of camera would suit a scope with this focal length for faint dso's, i have a gp290c for the planetary side of imaging. Sorry for the bombardment of questions.
I am a newbie on this forum, this is my first topic here but I would like to show you my recent planetary imaging results. I started to catch the planets with a dedicated planetary camera last month but never thought that a small 4" Maksutov can show such small details. The equpment I used:
SW 102/1300 Maksutov 2.25x Q-turret Barlow lens QHY5L-II color camera EQ-3 GOTO mount All the images were taken on differend countrysides in Hungary. I hope you will like it
Also, please share your images taken with similar OTA, I'd like to learn some tricks from others as well
Jupiter's 15 minutes of rotation. Captured with Firecapture, processed in AS!3, Registax and WinJUPOS (2020.08.21)
Saturn, 1 hours stacked with AS!3, processed in Registax (2020.09.05)
Mars, 3 hours of rotation. Captured with Firecapture, stacked with AS!3, processed in Registax. (2020.08.22)
Mars again, 5 minutes stacked in AS!3, processed in Registax. You can see also Olympus Mons and Arsia Mons next to the terminator (2020.09.05)
Finally, a result of a Hungarian star party where I learned how to use properly my equipment This time I borrowed an ADC for Saturn.
Hi there! I am seeking for advice from you good people.
I want to create a setup for stargazing which is fully automated. Ideally every process like scope calibration, guiding, tracking, focusing and taking photos should be done through WiFi, preferably from an iPad tablet.
Planetary imaging is the main purpose. I don't really care about deep space imaging.
I want the whole setup to be rather cheap, small and light, at the expense of imaging quality.
I am a total noob (used to play with an ETX-70 lots of years ago), but I really need the functionality I have described above.
I am thinking of using the bellow components and kindly request that you correct/add to the list:
1) AstroFi 102
2) A ZWO camera suitable for planetary imaging (any ideas for less than or equal to $250)
3) An auto focuser and motor drive (any ideas)
4) Smth like an ASi air device?
Is a guider necessary for planetary imaging, by the way?
Do you think I am in the right path?
I still have not been able to really comprehend the full picture. Is what I am asking for doable?
Thank you very much in advance!
