Two Sharpless objects -- one cool, one boring

Posted By Thomas V Davis
Here are two different Sharpless objects. 82 is pretty cool, and 83 is small and boring. Still, the region around 83 has some overlooked interesting objects.

Make sure you check out the OSC data for each image. They give a different perspective on each region.

Best regards,

IC2177 narrowband redo

Posted By Thomas V Davis
I've been waiting for the clouds to clear by reprocessing some old data. Here is IC2177 in SHO palette redone.

Like Stevie Wonder shooting archery...

....is how I feel sometimes when I try to image the more obscure dust clouds along the galactic plane. My goal in these images is to illustrate the faint dust that is not often seen. This dust seems to be best seen near reflection nebulae (makes sense) but it has been poorly mapped and so when imaging it is hard to know how to frame the image. Pointing the mount to the cataloged reflection nebula does not always center the extent of the dust.

Here is an image of vdB 123 in Serpens. As you can see, even though vdB 123 near the center of the image, once again there is more dust that would have been nice to see in better detail than what can be provided by the OSC data.

I know it is sometimes "artsy" to have a portion of your subject extend off the canvas, so I'm going to say that was my intent!

Anyway, I think it turned out pretty well, and my goal of demonstrating reflective dust in the region has been illustrated.

M8 region

Posted By Thomas V Davis
I've been wanting to shoot this region for a number of years. So, now that I tried I decided to go for some exposure time. Again, my goal was to see if I could tease out any "new" nebulous objects that are not usually seen. The main one that jumped to my eye was the light blue halo surrounding and overlying M8 itself. I normally don't see this as I suspect it gets processed out. M8 looks bright in my image but that is on purpose, so to see this nebulous structure. Also, I left the HII regions hydrogen pink rather than darkening them so to see them better. I hope this is not too offensive to your eye.

M8 and M20

Posted By Thomas V Davis
I haven't posted on this forum for a while but I recently reprocessed my M8 data -- less sharpening and less luminance for color fidelity. I know it is a little more saturated than many people like, but as I get older the more I like a colorful image. Also, M8 looks a little too bright but I believe it is the blue haze that makes it look this way -- I love this bluish haze that surrounds and overlaps M8. Enough of the excuses, here it is:

Not your usual Iris

Posted By Thomas V Davis
Taking a little break from the vdB catalog, I decided to image NGC7023 again. I haven't done it since 2007. I really like this target since it was the target that got me interested in shooting dust.

This time I decided to image NGC7023 for a modest exposure time and stretch the data like crazy to see what dust I missed before. This is what I came up with:

http://www.tvdavisastropics.com/astroimages-1_0000ca.htm

The data was G2V balanced and care was taken to the histogram during the steps of processing so I think that the slight magenta cast in some of the stellar regions is true. Possibly an reddening effect of the intervening dust?

This is not your usual Iris; I hope you like it.

M31 trial

Posted By Thomas V Davis
My first try at a mosaic, of sorts. 6 panel luminance mosaic combined with OSC color data.

305RHA in my observatory!

Posted By Thomas V Davis
I finally got to put the 305RHA in my observatory. I don't have a first light
image yet but hopefully soon as the weather permits. Here are a couple of images
of the setup from my website (scroll down for a view from a different angle).

These images have the STL11K on the RHA but I will soon receive my Proline-16803
from Australia and after I get an adapter made it will replace the STL.

Hopefully some astroimages soon...........
