That really sucks. Especially for a beginner. There are just so many issues to deal with. Astrophotography, no matter how it is advertised, just is not easy. Compliments and admiration for sticking

The Orion trapezium.. Impressive Stan, Just out of curiosity, is it possible these days, in one shot, with a Meade/Celestron SCT to get Sirius and the pup? I've been out of astrophotography

I have spent the better part of a year trying to figure out why I had coma issues with my focal reducer on my Edge HD14. I thought my imaging train was wrong in terms of respecting back focus specs

"Ford vrs Cheny" Lol, Yeah, btwn that and unnoticed auto spell correction... Thanks for noting, .. and brightening my day Keith

" Beware that there have been several reports of supposedly defective Edge reducers. " Oh no..... Lurking in the background, evident from my 1st night out, are small but obvious red and blue

I'd have to disagree that guide scope problems are endless. In my experience, and I see one other poster's, in the 1800mm FL range, they are all resolvable, reasonably. And once they are, one can for

"Ford vrs Cheny" Right. Celestron and Meade both yield very good value. BTW, you are about as good a typist as am I <g> Stan

" C11 EdgeHD at f7 is better ...," Beware that there have been several reports of supposedly defective Edge reducers. So your journey may yet have some twists and turns even after addressing most

Well, so far I'm still in the Meade camp, that is for sure. But I see this as Ford vrs Cheny, Honda Civic vrs Toyota Camry. Etc. Hopefully once I get this star drifting problem resolved, I'll

I think the writer said coma is not the main problem, and did acknowledge that there is some. But he wandered between the photographic and visual perspective, with not a lot of warning. The eye is

"C14 @ F5 guided with a piggy backed ..." That would be 70" FL (C-11 at prime = 110"). What is your avg and best FWHM (in arcsec)? I do not argue that piggy-back is impossible for larger

Thanks Bob, I'm sure there are hundreds if not thousands of imagers who are successfully using a guide scope arrangement at the focal lengths we're talking about. And they're using it for all the

Hello Alistair, Omg, 7000 GBP? Something just not right there... An open Invitation/opportunity for black marketers I would think. Or a lot of sales of nearly new scopes, bought off Astromart, CN,

I have an 11 year old C14 @ F5 guided with a piggy backed 4” F7 Stellarview refractor mounted on an AP1200 and I get excellent up to 20 minute guided sub exposures. I use a SBIG Remote Guide Head

Hello Keith, Since Celestron / UK dealers / UK importer has the bare faced cheek to charge 7,000 GBP for the 11 EdgeHD (11,000 USD), then I personally would not touch the insides of it until the 2

Yes! interesting, and entertaining... I have my own horror story of flocking the inner OTA. Guess what happens to the stickum of the flocking when the OTA sets under the beating sun of a few hot

"An interesting article..." That article contains a few untrue myths itself (e.g. the ridiculous claim the classical SCT has no coma). Watch out! there is a lot of misinformation out there.

"Meade is made better and has less problems in my experience" My experience is the exact opposite (3 Meade scopes vs 4 Celestrons)...

Hello Alistair, Thanks for yours. As you did with your C11, and the night before your note arrived here, I realized that an alignment check at the zenith, and then 45 or so deg either side might
