IC 410 - Ha and HaRGB

Posted By Jim Thommes
Here is data from late 2010 on IC 410. I have both a HaRGB and an HA image processed. Images and details can be accessed here:

Scope - Explore Scientific MN152 Mak-Newt at f/4.8
Camera - ST8300M (Astronomik HaRGB filters)
Mount - G11/Gemini
Guiding - Megrez 80 mm at 555 mm FL, DSI Pro, PhD Guiding

NGC1907 and M38

Posted By Jim Thommes
I was fooling around with the little camera while the other camera was catching photons. Here is a quick image of M38 and it's little brother - NGC1907:

Sharpless 261 (Lower's Nebula)

Posted By Jim Thommes
Sharpless 261 (aka LBN 864) isn't imaged a whole lot, but here is my recent
effort:

http://jthommes.com/Astro/LBN864.htm

RGB and H-Alpha images as well as details are on this page. Full resolution
is accessed by clicking the images.

This was taken with my Mak-Newt 152 mm, ST8300M and 1-1/4" Astronomik HA RGB
filters (last time on these filters - I got the CFW5 and a Baader HaLRGB
set).

NGC 2353

Posted By Jim Thommes
Here is a cluster done with the little camera. NGC 2353 is in the upper right. The background red is a part of the faint LBN 1036 emission nebula. Image and details are here:

IC 443 Ha and HaRGB

Posted By Jim Thommes
I have a late season shot of the Jellyfish. Image and details are here:

http://www.jthommes.com/Astro/IC443.htm

Both Ha and HaRGB are on this page. You can click on the images for full size.

Eta Gem is in the image and you will notice the "V" artifact in it. I get this with all bright stars with my Mak-Newt. I think it is due to the focus tube which has a slight intrusion into the light cone when the camera system is in focus.

Scope: ES 150 mm Mak-Newt at f/4.8
Camera: ST8300M Baader RGB and Ha filters
Mount: G11/Gemini

IC 2169 and Friends

Posted By Jim Thommes
I wanted to do a straight LRGB image since I had been doing mostly Ha LRGB stuff. The IC 2169 area seemed like a good opportunity.So the image as well as details are located here (you can click the image for a larger version)

http://www.jthommes.com/Astro/IC2169.htm

There are other IC identifications for IC 2169 and IC 2167 (IC 447 and IC 446 respectively). I know there are three van den Berghs in the image (two buried in IC 2169) and all the NGC/IC objects are identified in Lynd's catalog as well.

Scope: Explore Scientific 152 mm Mak-Newt
Camera: ST8300m (Baader filters)

IC2177 Seagull

Posted By Jim Thommes
OK I have been out of town - then back working like crazy, so this image from my backlog is a bit out of season. It is the Seagull before it went away until next year. I'll catch up soon with some galaxies. Image and details are here:

http://www.jthommes.com/Astro/Seagull.htm

There is a larger image and Ha image link on the page.

Scope: Megrez 80 mm APO at f/5.8
Camera: ST8300M Baader Ha RGB filters

M106 and some friends

Posted By Jim Thommes
Here is an image of M106 - seemingly a popular target this year. The field includes NGC 4248 and NGC 4231&32 as well as numerous background galaxies. The one notable absence from this somewhat smaller field is NGC 4217 (which would be off in the lower right). Image and details are here:
