By the way, if you want to see the gory detail (aka my ramblings) of the experience of buying and setting up the scope - see http://www.pbase.com/gailmarc/image/153663053 and download the PDF. It's only 17 pages long!
No. Not until I do Ha. I never do 30 min LRGB subs - waste of time. I'm also interested in seeing if there is any flexure, but it will have to wait until I do a neb shot.
A keen eye and a tight zoom there Paul . As it happens, you're critiquing my hasty processing. I was careless and used an action with a minimise filter step (bad Marcus!). If you want to see the raw (except for stretching) picture see: http://upload.pbase.com/gailmarc/ima...94720/original
There is a new camera in my future too
236mm optimally. I have a motorized secondary so I can change it. But I'd need to be careful not change the mirror spacing so much as to degrade the image.
Cheers, Marcus
That looks better on the segmented shot. Looks good.
I don't mind doing 30's, I find I can go deep really quickly and then polish off the background noise by doing a few more. I don't think it is a waste of time though. Each to their own though.
Which camera are you looking at? STX I take it? The STXL is quite nice but sensor is the limiting factor I suppose.
Hmm not much back focus, though it could suit my imaging train.

Yep, only do 30s for NB (Ha only at this stage). For LRGB I've never done more than 15 - even with the Tak and that's done me well.

STXL actually. Call me weird, but I still like the old 35 mm frame and the STX is a monster. I like the fact that you can integrate the OAG/Filters and AO-X on SBIG gear.

Yes, but I have a corrector AND a rotator If I go the STXL route I'll have surplus backfocus I think.
The STXL is a really nice camera. I have been using mine for a couple of months or so and it is nice to image with, the integrated guide camera in the filter wheel is excellent.
I will have a read of the review., let you know what I think later.
That's looking really good Marcus, you've made good progress learning how to collimate this beast (have you named it yet?); stars still just a tad elongated towards the upper right corner but I am being picky

Thanks David - and I always appreciate your opinion, no matter how picky ! I know it's not perfect, so once I get an image or two under my belt (because I'm suffering major imaging withdrawal right now) I'll go back and do some tiny adjustments to see if I can remove the remaining elongation. I'm pretty sure I can. Right now though it's good enough and I can probably process residuals out.
A name? How about OSSIS (Officina Stellare Sensational Imaging Scope)?? Or SPOT (Semi Perfect Optical Telescope). Or BORIS (Bells Observatory Rc Imaging Scope). I dunno, you're the acronym expert - any ideas?

Greg.
Thanks Greg. Yep, playing with fancy new toys is always fun!! It's been an education moving from a refractor to a reflector though, that's for sure! There's been a pinch of fear (I spent a few bucks on this thing), a smattering of frustration and a good helping of "doh!" moments - mostly as a result of my ignorance. The story has a happy ending though!

You guys crack me up! but I don't think I'll be naming my scope after all. I'm happy to announce, however, the winner of the naming competition would have been .....
David Fitz-Henry, who started this frivolity without making a meaningful contribution, is eliminated. .... So, David, it's time for you to leave the Iceinspace kitchen.
