Canon 5D3, 16-35 f/2.8L II - ISO 3200, f/2.8, 16mm, 30 seconds (right around the 600 rule)
Within Adobe PS CS6' ACR tool: cooled the temp to 3300K w/ -2 tint, contrast +98, clarity +48, vibrance/saturation both +21, +52 NR w/ 82 detail, and a very slight crop.
Hope you guys enjoy and find the details helpful.

The first two were taken on a river/camping trip outside Citrusdal. The third image is part of a time-lapse sequence shot North of Tulbagh.
The third image is lovely!StudentOfLight said:Some wide field astrophotography. Hopefully I can help bring this thread back to life.

Love that looping dust lane with three nebula, a golden one, a pink one, and a blue one, towards the lower left corner (that is part of the constellation Scorpius, the yellow is the star Antares, the pink is Al Niyat, and the blue is IC4603). Freakin amazing image.

Very nice work! Is the third image not a stitched pano?

I like the third image the best. What was making the bright light?

My most recent Astro pic
Thanks for the advice. I'm really looking forward to my next trip which will be into the desert so much less light pollution as well than my previous shots.jrista said:Nice milky way view there, Student.
If you want to stack, you really need to use full RAW. The Canon mRAW format is actually more like a JPEG than anything, a 4:2:2 encoding of Y (luminance) and Cb (blue/yellow channel) and Cr (red/green channel). It is 14-bit, but it is actually not even remotely "raw". Stacking non-raw images doesn't produce nearly the same kind of results as stacking true RAW images.
For stacking to be most effective, you also want to have fairly closely temperature matched "dark frames" (same exposure time, ISO, and temperature...within a few degrees), say 30 of them, as well as about 150 "bias frames" (same ISO, shortest possible exposure time like 1/4000th or 1/8000th...super easy to create, and the more you stack, the better they are to calibrate.)
Once you have some real RAW lights, and some darks and biases, then you can stack with DSS, and the process is largely automated. Export as a TIFF (WITHOUT applying modifications), and you can do some pretty amazing tweaking and stretching in photoshop.
