The Flying Bat - Sharpless 129

Posted By Jim Thommes

Here is an image of Sharpless 129. Signal was a bit weak in my data, but I pushed and stretched. I do not take any credit for the name - I saw it on the internet - really. But in looking at the image, you can imagine something flying. Image is at:

Dusty LBN 534

Posted By Jim Thommes

LBN 534 is a reflection nebula. But as you can see from the image, it is involved with a bit of dust. It is on the border of Andromeda and Cassiopeia. A full size image is here:

NGC1333

Posted By Jim Thommes

This kind of an interesting nebula. Some of our Astromart colleagues have done some real nice images of NGC 1333. I actually took some H-Alpha data for this reflection nebula - I picked up a few H-Alpha photons. Its also kind of dusty in the region. I wasn't aware how close NGC 1333 is to constellation borders. This image is partly in Perseus, Taurus, and Aries. Image is here:

Dusty Cluster - NGC 225

Posted By Jim Thommes

NGC 225 sits in front of a dark lane and it appears to have a little reflection nebula involved (LBN 604). Its also known as the Sailboat Cluster - I think I can see why. Image and exposure details are here:

The Pleiades

Posted By Jim Thommes

Here is an old standard - M45. I did do some significant time on it with multiple exposure sets up to 10 minutes. Some of the stars came out a bit funky - I think it was the optics - not really sure. Other than that , I'm happy with it. Image and exposure details are at:

LBN 1022 - a nearby brightening taking place?

Posted By Jim Thommes

Here is an image of LBN 1022. Look at the cropped image on the page (link below) that points out a small nebula. I have looked on the DSS slides and this nebula is much dimmer. Is it a known brightening nebula? Anyone take any pictures of this area recently? I would appreciate any help or information anyone could provide to me.

The C8 optics let me down a bit on the image, but the image and exposure details are at:

http://www.jthommes.com/Astro/LBN1022.htm

The region of this 36 arc minute wide field is Equatorial 2000: RA: 06h 56m 52s Dec: -08°16'19"

The Flame - NGC 2024

Posted By Jim Thommes

This is not often imaged as a central feature, but here is the Flame Nebula. This is an 18 x 6 minutes (ISO800) exposure set. I was rewarded with a substantial reflection in the lower part of the image from Alnitak. I managed to make it unobtrusive, but the lower part of the Flame may have an inaccurate color. Image can be seen here:

Camera - Canon 350D ISO800 no filters 18 x 6 minutes 8 Darks
Mount - G11/Gemini
Guiding - Megrez 80 mm at 555 mm FL, DSI Pro, PHD Guiding

I was actually a bit surprised on How Alnitak came out (better than I expected) - and on a C8 yet, go figure.

IC 405 - 410 HaRGB

Posted By Jim Thommes

These objects have gotten a bit of attention this season so far. Here is an HA RGB version done recently. This is done with a SIGMA 150 mm DSLR lens. Image can be seen here:

LDN 1622

Posted By Jim Thommes

Greetings All,
It has been quite a while since I have posted anything or participated in the forum discussion. Seems I have been working way too much and the weather has had a bad stretch in my area (which normally has clear skies at this time). I hope both work and the weather changes....

Here is an image of LDN 1622 which I managed in February this year. It is a dim object (I guess I should expect a dark nebula to be dim). Its in Orion just outside the bright section of Barnard's Loop. Image and exposure / processing details are here:

M108 and the Rosette Nebula

Posted By Jim Thommes

No, I don't have that wide of field image to include both objects in one frame... But, after short focal length Nebula season and some weather challenges, it is time for some longer focal length activity. Boy, am I out of practice. Here is M108 - I seem to be always challenged by this guy. M108 image and exposure / processing details are at:

http://www.jthommes.com/Astro/m108.htm

Scope: C8 at f/8
Camera: Artemis285 Astronomik LRGB filters
Mount: G11/Gemini
Guiding: Megrez 80 mm at 555 mm FL, DSI Pro, PhD Guiding.

So the Rosette was a DSLR effort from an earlier evening on a different setup - this was a wide field effort:
