Pickering's Triangle

Posted By Jim Thommes
Bruce just posted a nice image of this same object in a wider field. Here is one I did with RGB data.

A full size image with exposure and processing details are at:

Scope - Megrez II APOgrade, Camera - Artemis285.

Red Globular - NGC 6366

Posted By Jim Thommes
Well, This is somewhat of a plain image. I just thought it was interesting about how red this particular globular is. It is supposed to be abundant in heavier elements and it's light comes throgh some interstellar dust.

Full size image and exposure / processing details are at:

http://jthommes.com/Astro/NGC6366.htm

It took a fair amount of exposure for a globular - L:R:G:B - 40:16:16:16 (RGBs binned)

Veil Nebula

Posted By Jim Thommes
Here is an image I got of the Veil earlier this month. I processed somewhat aggressively, my data is always a bit short.

A Late Season Swan

Posted By Jim Thommes
This is an Ha enhanced RGB image in that the Ha data was used to construct the luminance channel in an LRGB image. I did bias slightly toward the red over my normal color calibration.

Also, based on past comments, I did this without noise reduction. (Of course this object is fairly bright and has good signal to noise.)

Full size image and exposure / processing details are here:

An older imade from two years ago - made without Ha data is here:

IC 1284 Region

Posted By Jim Thommes
IC 1284 is an object often seen in wide field images of the Sagittarius star cloud region. Here is an image of it isolated in a narrower field. There are several objects along with IC 1284 - IC 1283, NGC 6989, and NGC 6990.

A full size image can be seen at:

http://jthommes.com/Astro/IC1284.htm

This image was taken with an Artemis285 along with a C8 and Meade 0.33x Reducer/Corrector operating at 0.41x.

Cave Nebula SH2-155

Posted By Jim Thommes
Here is the Cave Nebula. This was a Ha enhanced LRGB. Full size image is at:

http://jthommes.com/Astro/SH2-155_Cave.htm

This was done with my C8 at f/3.3 and Artemis285 Astronomik 13nm Ha.

I had done this object about 2 years ago...

NGC 7023 - Narrow Field

Posted By Jim Thommes
OK, Vince Bert isn't the only one to obsess with the Iris.... I liked his "study" a lot - gave me some inspiration.

So this one suffers a little on depth and noise but after all, it is only 1-1/2 hours total at f/6.

Different Double Cluster - Cassiopeia

Posted By Jim Thommes
Here is a different double cluster than the more famous one in Perseus. The clusters are NGC 7788 and NGC 7790. Full size image and exposure / processing details are at:

Cocoon - HaLRGB

Posted By Jim Thommes
Jim Brown had recently posted his great image of the Cocoon. Here is a version I did also in September. Full size version is at:

http://jthommes.com/Astro/CocoonNeb.htm
Click the image for a full size JPEG.

Exposure was:
H-Alpha - 7 subframes, 7 minutes ea ( I was feeling lucky that night)
Full Spectrum Luminance - 5 subframes, 3 minutes ea
RGBs - 6 subframes 1.5 minutes ea (2x2 bin)
Optics were at f/6.

Pleiades - M45

Posted By Jim Thommes
No H-Alpha for me on this one...

I have never done real well this object. But new optics, a new camera helps a lot - this effort came out a bit more promising then past efforts.

Full size image and exposure details are at:

Take a look at an earlier 2003 effort:
