Moon Sunday Morning

Looks very nice despite the conditions. Very good contrast, and the detail along the terminator is very good.

California Nebula

The California Nebula is a challening object even with regular CCD equipemnt. Your D60 image is very beautiful.

Easy equates to ABG. You do not have to worry about blooming. You will need to take iamges that are about twice as long, however, since the anti-blooming features cut down the amount of light that hits the pixel. So it is a trade-off - do you want the convenience of no blooms, or the convenience of shorter exposures and some bloom removal?

Here is a 1x color image, a combination of the luminance in really good seeing and older color data taken just after I set up the remote telescope.

NGC2244 a rose?

Posted By Ron Wodaski

Looks very nice. I think you may have some flat-field issues, however; you are kind of bright in the corners. But the exposure, focus, rpocessing, and detaisl in your image look great.

Nice seeing? I'll say. Better than I've ever gotten for imaging, that's for sure. The best visual night I ever had was at about this level, in a 16" Starmaster Dob. A beautiful image.

I tried my hand at curing the blue limb (not uncommon) at left and applied a little additional sharpening just to see what it looked like. To reduce the blue limb, I used the lasso tool to select just the limb, feathered by 25 pixels, and then used the midpoint slider in Levels to move the green and blue channel midpoints further to the right. This was a partial cure; careful work with the original data would probably take this further. I in effect darkened the blue and green channels in this area relative to the red. I darkened the red as well; the limb was just plain brighter than it should be. The result is below. let me know what you think.
