Do you have a full sized image that we can see, Jim?

Abell 4 Plus Galaxy ID Help (or Challenge?)Posted By dan kowall |

It takes a bit of time to learn the interface, but it's well worth it.
Good job on Abell 4. Those small planetaries always make me yearn for a really long focal length scope.

Achieving max resolutionPosted By dan kowall |
Hi Rolando,
You're preaching to the choir with me. Per someone's suggestion, I started shooting globulars in RGB, unbinned a while ago, was impressed with the contrary-to-popular opinion results, and use it as my standard protocol for almost all targets now.
Your results put method to my madness.
Incidentally, image number two is labeled "1 x 1 binning" rather than 2 x 2.

M33--My Best Capture to DatePosted By dan kowall |
Hi Jared,
The reduced image that you posted looks good, though it's always nice to see a full-sized image.
Why are you going with a hot pixel map rather than a dark?

SN2009lb - a dim galaxyPosted By dan kowall |
Those are fine star colors, Charlie.
The next time that you're faced with limited time for exposures, especially in a star field, try just the RGB.
You'll get better results from your data rejection procedure, and you can always make a synthetic luminance from that data, should you feel the need.

The Flame - NGC 2024Posted By dan kowall |
That looks pretty good, Jim.
Clicking on the image takes one to the full-sized version of the Flame, but clicking on the link below goes to a version of M 45.
Some of your larger stars show the two dark spikes that one sees with petzval scopes. I wonder why.
The color looks good to my eye and I think that you handled Alnitak well.

I think that observatories are like boats, you need to name them.
Have you christened yours?
