Emission Nebs in Cygnus - Sharpless 115 and 116

Posted By Jim Thommes
I have been exploring the less traveled HII regions in Cygnus. Last week I had posted an Sh2-112. This week I have SH2-115 and Sh2-116. Full size image and exposure / processing details are at:

http://jthommes.com/Astro/SH2-115_116.htm

Also in this image is a surprising good sized Planetary - PLN 85+4.1 (in the upper right of the image).

This image was from my Artemis285 on my Megrez II @f/4.6

Last week's Sh2-112 -

Sharpless 119

Posted By Jim Thommes
I am wrapping up some of my travels through some of the less traveled HII regions in Cygnus. Here is Sharpless 119. It is about 3-1/2 degrees from the North American Nebula (opposite side from Deneb). A full size image and exposure / processing details are at:

http://jthommes.com/Astro/SH2-119.htm

This one was done with a Vivitar 180 mm SLR lens and my Artemis285.

Sigma Scorpii and Sharpless 009

Posted By Jim Thommes
Many of you have seen images of the Rho Ophiuchus region. The colorful red region above M4 is this Sharpless object - SH2-009. The energizing star is the Magnitude 2.9 Sigma Scorpii. I made a close up image of just this object (well if you want to call 84 minute FOV a close up). Image as well as exposure and processing details are here:

http://jthommes.com/Astro/SH2-009.htm

The scope was my Megrez II 80 mm APOGrade; Camera was my Artemis285

This was a short subject (even for me!) Ha:R:G:B - 35:6:6:6

Cedrblad 214

Posted By Jim Thommes
Or, otherwise known as Sharpless 171....

Hi Folks,
This is an image of Cederblad 214. Image and exposure / processing details are at:

http://jthommes.com/Astro/NGC7822-CED-214.htm
(be sure to click on the image for a full size view)

The Scope was my Megrez 80 mm APO at f/4.3 (with a Paul Rini reducer), Camera was my Artemis285.

An earlier version of this object (ToUcam Mosaic) taken in 2004 is here:

NGC 6871

Posted By Jim Thommes
Hi Folks,
Here is what was meant to be a quick image of an open cluster I had not imaged before. Clouds came... RGB's rescheduled for another night. Then some weird gradients in the Red. Anyway I finally got it done. Here it is:

http://jthommes.com/Astro/NGC6871.htm

This was done with my C8 at f/3.7 (with a Meade 0.33x reducer) and Artemis285

NGC 7380 - Ha LRGB

Posted By Jim Thommes
Here is the cluster NGC 7380 and the emission nebula SH2-142. The cluster is somewhat hard to see because of the scale - I was concentrating and processing for the nebulosity. A full size image and exposure / processing details are at:

http://jthommes.com/Astro/NGC7380.htm

C8 @f/4.2
Artemis285
Astronomiks 13nm Ha
Edmund Optics RGBs
Ha - 8x8min (1x1)
RGBs - 6x2min (1x1)

For comparisons, I have an earlier image I made in 2004 here:

M2

Posted By Jim Thommes
I took a break from nebulas to do a globular. Here is M2 - a relatively dense glob. I was trying to get depth while still resolving the core. I think I'm happy with the results.

Crescent Nebula

Posted By Jim Thommes
Greetings All,
I made an image of the Crescent - NGC6888. This was an Ha enhanced LRGB with the Ha providing a lot of the detail in the Luminance.

Full size image and exposure / processing details at:

http://jthommes.com/Astro/NGC6888.htm
(be sure to click on the image for full size)

This was done with my C8 - Artemis Camera and G11/Gemini. I am guiding these days with a new DSI Pro (terrific prices these days).

I had imaged the Crescent back in July of 2004. You can take a peak at that image here:

Bubble Nebula

Posted By Jim Thommes
Greetings all,

I have done the Bubble in straight LRGB in the past I wanted to get an Ha data set and some RGB color for it as well. A full size image and exposure / processing details are at:

http://jthommes.com/Astro/NGC7635.htm
(be sure to click on the image for full size)

This object would probably be best in a tri color narrow band (too bad I only have an Ha), the RGB gives a little hint of what is there.

Instrument: C8 at f/4.2
Camera: Artemis285
Mount: G11 / Gemini
Guiding: DSI Pro and K3CCDTools with WO Megrez 80 mm

Here is the earlier 2004 version.

NGC 288 - Globular Cluster

Posted By Jim Thommes
Greetings All,
Here is a southerly globular cluster. It is a pretty loose globular (class X) and therefore an attractive globular to image if you can reach it from your latitude. A full size image and exposure / processing details are at:

http://jthommes.com/Astro/NGC288.htm
(be sure to click on the image for full size)

You can pick out a couple of dim galaxies - PGC3068 and PGC766121 in the field.

C8 @ f/7.5
Artemis285
G11 / Gemini
Guided with WO Megrez 80 mm APO, DSI Pro, K3CCDTools
