Not to beat a dead horse......

Posted By Thomas V Davis
My imaging has been shut down for quite some time due to a variety of factors :S , so I decided to reprocess an image using some different techniques. Since this seems to be the Horsehead Nebula time of year, I chose to reprocess my 2005 image of this region. Here is what I came up with:

Hopefully I will be able to get some new data soon, but until then I'll keep watching all of your nice images.

Best,

First in a long time -- M97

Posted By Thomas V Davis
It has been forever since I have been able to post an image. I thought I'd try a longer focal length during the spring and shoot a few targets that I've never done before. Here is M97. I'm not overly pleased with the outcome but I have become very rusty over the past few months. Also, my collimation is off so the stars are soft......

Anyway here is my attempt at the Owl Nebula:

LX200R 12"
AP .67x reducer
ST-10XME
LRGB 135:70:70:70 minutes 2x2 binned

M3 - First light LRGB

Posted By Thomas V Davis
I have recently taken shipment of an ASA N12 f/3.8 astrograph and this image is the first light LRGB. I decided on a globular cluster to see sharpness, field correction and depth of light grasp. I've never shot M3 and it happened to be handy.

Here is a link to what the telescope looks like:
http://www.tvdavisastropics.com/astroimages-1_000004.htm
It is a carbon fiber OTA with a 3" Wynne corrector. It seems to handle the STL11k quite well. Its central obstruction is a little larger than I would like (39%), but it is still smaller than most RC's. The focuser is a JMI NGF-X 3". BTW, that is not a corrector plate on the front of the scope -- it's the end cap!

I am optimistic with this first light LRGB.

Best,

Tom

M13 - a wide view

Posted By Thomas V Davis
I shot M13 this last week through the moon pollution. I haven't done it in years so I thought I'd do it again. I still is a beauty.

Details and a view of the core at link:

M13 reprocesed - same data, different day

Posted By Thomas V Davis
I'm sorry for this post, but I reprocessed my recent M13 to bring out more of the halo stars. I just thought I'd share it.

First completely unattended image -- vdB142

Posted By Thomas V Davis
This is my first completely unattended imaging project. This was taken over a few nights and I slept through it all!! I used CCD Commander to start the cameras, slew to IC1396 after it reached 40 degrees elevation, take the various Ha, R, G, B frames, focus on a nearby star every 30 minutes, and then at the end of each run park the mount and take darks, then finally warm up the cameras. All I did was get up in the morning and power down the computer and close the clam dome!! I almost feel a little guilty (almost)!!

Anyway sorry, but I'm so excited to get more data this way.

IC1396 and vdB142:

NGC7023 and regional dust

Posted By Thomas V Davis
I took an image of this region in Cepheus late last summer, but I wasn't happy with it so I decided to try again - this time with my 12" f/3.8 astrograph (my actual f-ratio is 3.51 with the Wynne corrector).

This is NGC7023 and its surrounding dust clouds. I have a version (not on my website) that has been pushed and there are knots and clouds of dust everywhere!

I hope you like it. Comment and criticism are always welcome.

vdB152/Cederblad201 in Cepheus

Posted By Thomas V Davis
I have never imaged this dim object and so I thought I'd give it a try. You know, try something easy - hah. Anyway, I think it looks like a cosmic monster sucking up stars as it crawls along -- look, there are three in a row ready to be eaten!!

http://www.tvdavisastropics.com/astroimages-1_00001b.htm

I found this region challenging to process with all it's subtle details.

I hope you like it. The attached image is a cropped view of the central nebula.
