M92

Posted By Jim Thommes
This is an M92 that I took during some relatively good seeing.

M12

Posted By Jim Thommes
Here is M12. Seems to be a bit noiser than my earlier M92. Dan Kowall just posted an M92 and commented - "It took me much longer to process than to gater the data". Man ain't that the truth. Globs can be a challenge to process.

IC1274 - IC4685 Region

Posted By Jim Thommes
Here is some color for the fourth of July. I did a two frame mosaic of this region. It's not as colorful as the Rho-Ophiucus region, but I think it is a close second.

I also have individual halves for inspection. I mis-aligned the frames a little when I took the data so the framing on the mosic is not ideal. The individuals have more width to them.

Full size images are here:

M68 Globular Cluster

Posted By Jim Thommes
Here is an M68... I am suprised at the blue color (of course, I could have made a mistake in my data or processing). Other images I have seen seem to show it blue as well though.

M62

Posted By Jim Thommes
Ok, So here is another globular cluster I did (the last posted was M68). Here, M62 is in a richer star field since the Milky Way is in the background. I have attached a mid sized image, but a full size image and processing details are at:

C8 at f/8, Artemis 285 Exposure, a very short 12:4:4:4 (LRGB)

NGC 6357 - Emission Nebula

Posted By Jim Thommes
Here is an emission nebula deep in Scorpius. It's one of my early images from my Megrez II 80 mm APO Upgrade.

Scorpius Globular - M4

Posted By Jim Thommes
Here is an M4 at somewhat low f/ratio and short subs exposure. I am amazed at how red this turned out but I hear that there is dust between us and M4 that creates the reddish appearance. This is a mid size image. A full size image and processing details are at:

http://jthommes.com/Astro/M4.htm

Exposure was in 60 sec Lum subs and 45 sec RGB subs (2x2)

North American HA-RGB

Posted By Jim Thommes
All,
I'm back from a little R&R from work. A lot of very nice images posted this last week - Congrats to all.

Back in late June, I took some data on NGC7000 - a two frame mosaic. I have assembled it all and here is a posting.

I used the HA for Luminance and did not mix any HA into the color processing. The image shows a bit of reflection with NGC7000 along with the expected red HA emission line. I mostly see images of NGC7000 with the red pretty prominant - not as much with this image. I am color calibrated, but of course errors can creep in.

Anyway, please take a look at the full size image here:

Ha:L:R:G:B 36:12:9:9:9 (each frame)

Also, I have an earlier version of the Wall area here:

Cat's Paw - NGC6334

Posted By Jim Thommes
Here is a image of the Cat's Paw from some data I got with clouds coming and going.

I was forced in the processing to mix H-Alpha data in with the RGB to avoid washing the color.

Full size image and exposure / Processing details are here:

http://jthommes.com/Astro/NGC6334.htm

Rather short exposures as the clouds allowed - I was lucky to get this data - HA:L:R:G:B 24:8:9:9:9.
