Fuzz...your intergalactic shots blow my mind. that one is seriously ridiculous. what is the blue'ish joint in the upper portion of the shot, another galaxy or a bright star?
FKNA! Siiiick shot fuz!
Can we get a TGR photobook thrown together please?

Hire these guys for the night, DUHHHHQuote:

That's some pretty nifty software you are using to combine and noise reduce those images too, very very impressive.
Thanks all.
As SchralphMacchio said, the camera is mounted on an equatorial telescope mount, which tracks the motion of the stars. I set up the camera to shoot 60-sec exposures through the night.Quote:

Yup, you got it. The calibration has to be pretty accurate for imaging. The better the calibration, the longer you can run your exposures. For such wide-field images, you don't necessarily need a long exposure. When I image through my telescope, then I'm running 10-minute exposures, where the calibration has to be very good. To help with calibration to get such long exposures, you have to guide (since even the best mounts have periodic errors -- I use an [ame="http://en.wikipedia.org/wiki/Autoguider"]autoguider[/ame]. For such a short exposure, I didn't guide.Quote:

A couple shots. First time posting in this thread. C&C welcome, let me know what you think. No post-processing on these.

figured it's time to post a couple...I've picked up some great tips in here.
All of these are pre-processing, still couldn't get that sun not to be blown out on the river shot though.:nonono2:
Fucking crazy what tools we have available to us now. 20 years ago I was dipping and dunking color film...Quote:

From THIS little adventure.
I really want to get back up there and take a series for later stacking.
These are from the American Le Mans Series race at Laguna Seca in May. No post production. The last one isn't a very good shot but it's the only one I got with the brakes glowing.

Those rodeo shots are incredible.
Awesome. You and mom must be stoked.Quote:
