Doug,I'm not Milby but that IS a galaxy. I've seen it identified in other photos. It has a NGC designation but I don't recall the number.


gxy top right corner = IC4263 class=SBc sze= 2.1' x 0.3' [Megastar] there are other smaller gxys in the frame.

milby - here's one I processed recently using the exact same data as that other Orion shot, but used more of an HDR approach. You can see the difference between the two. I like both, but the first always fealt more "natural" to me I guess. Not sure if that's really the right way to describe it.

Orion HDR


I'm testing out some screen capture apps right now, so if I get one that works to my liking I will record a couple of processing sessions to show what I do and post them up this evening.

mesmerizing stuff, Josh, and I am very interested to see your processing techniques. How did you get such wide fields? I have to mosaic to get a complete Rosette, let alone North America.

The Hyperstar 8" is only 425mm focal length, your 9.25 is 540 I think. The SXV-H9C is also 1392x1040 pixels on its array, my QHY-8 was 3032x2016 pixels. The focal length and chip difference make up for the variance.

I'm compiling the first workflow video right now. Just need to upload it and I'll post a link here shortly.

Well, uploading is not going as planned.. I'll see if I can straighten this out tonight and have it posted tomorrow. Sorry about that.

Josh, that Orion shot is amazing. One of the best I've ever seen. Seriously, great shot!

Your equipment shots are like walking through a candy store. Do you have any shots with the Hyperstar or an Orange tube? The Stellarvue on the CGEM is my personal favorite.

It's always neat to see the setups out there.

SO MANY TOYS......

Ok everyone, sorry for the delay.

http://daemongpf.blogspot.com/2013/03/workflow-video-1.html

I posted a link to the workflow video, but also included a link to the raw unprocessed FITS file which you are welcome to download and experiment with, or follow along on the video to compare the results.

Tim,

Thanks for the compliments!

I do have some other pics of that rig in action at White Sands during the annual star party, and I think at a few outreach events I've done at some local schools. Let me dig around and I'll post some up this afternoon.

Thanks, Josh. Does seem like a pretty straightforward processing routine for PS. The data you captured is marvelous, though, and thanks for including the unprocessed file. I played around with it in Pixinsight for a little while to see what difference, if any, that platform/approach would have (attached in forum-required sub-200K form). Different ways to skin a cat, I suppose.

That 8/QHY was a great Hyperstar rig for wide-field images.

Nice processing job. Looks good. I'll try to find some time to record my Orion processing since it involves a great deal more technique and workflow.

The data is genuinely so good that the pic almost processes itself. I'm particularly taken with the star colors - much more dramatic than what I've been able to get from the SXV so far. Thanks again for sharing your insight and experience!

If I recall correctly, the stack was 60 x 120 seconds, flat subtracted, no dark subtraction. I usually ran the camera on a gain of about 9%. The QHY-8 is a pretty solid performer for the price. Very low noise.

Only thing I would have changed is going to the QHY-8 pro (cylindrical casing vs. the big square casing on the original QHY-8 that I had). Plus the pro was regulated cooling rather than "always on, maximum".

Sorry, guys, I just haven't been keeping up with this thread but now on looking, I see there are some superb images here, notably from Milby !

My goodness though, this makes me envious ! Over here in the UK, we haven't seen the Sun in weeks let alone any stars !

By the way DaemonGPF, is that Stark Lab. "Nebulosity" I think I spotted there on your laptop which you're using for your capture/processing software ? If it is; just to say that I use the same, (weather permitting of course.....see above) !

Best regards,
Tel

Great stuff folks!

I'm happy to report - My hyperstar is on the truck for delivery today!!! and of course, my CSC is now blindingly white..

Those are really great Milby, really great. I have a CPC 9.25, the main advantage to hyper star is a really fast fl? About a fl2 or 3? May I ask what sort of camera your using? Really great shots you have,,

Outstanding captures Milby.

Looks like you've caught NGC5169 too, bottom left of M51.

Thanks for posting.

Regards. Peter.
