Eastern Veil - Epsilon 160

Posted By dan kowall
That looks really good, Tyler.
Could we have a look at a full size version?
Each night I go outside to look at clouds and wonder "Someone must have clear skies; I wonder who?" Well, from all of the images that you've been posting recently, I think it's you, Tyler. And I think it's time to share.

Third light with Orion Starshoot... M57

Posted By dan kowall
Hi Ivan,
That looks pretty good. Tracking and focusing have been well handled.
My only recommendation would be to take more exposures. As you know, the more data that you have, the easier the processing will be.
It's good to see you posting images.

IC7050 - The Pelican Nebula - from Utah

Posted By dan kowall
Nicely done, Tyler, and well processed.
You've captured a lot of the subtle gradations in the dust clouds.
You have your numbers reversed, though. It should be IC 5070, which refers to the volcano-shaped structure in the bottom right of your image.
My regards on a fine image,

M94

Posted By dan kowall
That's a great job on a difficult object, Jim. Even the large image looks good.
You have excellent star colors and great detail in the galaxy core.
I agree with Tom and Tyler that you have a mastery of your equipment.
My only suggestion for improvement on this image would be to soften the transition from galaxy to background. M 94, as you know, has a very extended outer halo including its unusual 'dark donut'. You would probably need long exposures from a dark site to see the 'donut', but I think that showing whatever halo data that you have (even if it's noisy) would be more 'faithful' to M 94's appearance. A lot of imagers believe that showing a bit of grain in an image is not a bad thing.

M57 -- 8" LX200GPS and DSI Pro

Posted By dan kowall
That's an impressive achievement, Taylor, both in acquisition and processing.
Should you wish to 'pretty up' the star shapes (though not really needed in my opinion), there are some articles here:

that may be of interest.

That looks good, Ralph.
The colors are right on, including the stars.

Scorpius Globular - M4

Posted By dan kowall
That's a fine job of processing, Jim. Even the large size looks good. It's got great color and it's not overly sharpened. That makes for a natural processing style.
I have seen some images of M4 that show some blue stars, such as Jim Misti's:
http://www.mistisoftware.com/astronomy/Clusters_m4.htm
You might be able to increase your blue saturation a touch.
Have you tried shooting a glob with unbinned RGB? I find the color easier to process that way, and it doesn't seem to affect the depth of the image.
I liked the M4 links to the mouse-over and other images on your site. The wide field views give us a good sense of M4's neighborhood.
My regards,

dan
