M31, M32, M110 - Canon D60

Posted By Ron Wodaski

Awesome image; amazing what you can do with the D60. That's _amazingly_ deep. Needs a little green reduction, however - do you have some light pollution where you imaged this? If I subtract the green, the colors neutralize nicely and there's plenty of blue and red detail that comes out. There's also a slight central hot spot, but this doesn't show up clearly until you rebalance color.

CCDSoft autoguiding question

Posted By Ron Wodaski

What version of CCDSoft are you using? This may have been changed in the most recent versions. Current released version is 1.0.70; current beta version is 1.0.72 (includes scripting support).

Your workaround is the right approach, however.

Saturn first try crude picture though

Posted By Ron Wodaski

Nice start! Seeing will limit what you can do. ALso, with single exposures, noise can be a problem. Try taking multiple images and combining them to average out the noise. How you combine will depend on what software you are using for image processing. I see Mike U. has replied; I'll bet he has some suggestions for Image Plus.

D60 M13

Posted By Ron Wodaski

Nice detail. A little green, however. From what I'm seeing, most of the D60 long-exposure images are tinted green. A little post-processing to remove the green cast would fix this.

D60 North American Nebula

Posted By Ron Wodaski

Nice work! Boy, these D60 images are really redefining what you can do with a digital camera.

This image has a green/blue central hot spot that was easy to remove using the gradient removal techniques from my book, as shown in the attached image. I simply selected the central portion of the image, and raised the black point of the green and blue channels simultaneously.

salvaged image--thanks Ron W.

Nice result; very good detail here, and lots of outer stars as well. A slightly lower black point might be good. I can see a bit of coma at lower and central right; a little touch up to collimation would be a good idea.

Best CCD mount for under $3,000

Posted By Ron Wodaski

Those scopes are all heavy, so your mount choices under $3,000 are pretty limited. The Newts, especially, are probably too heavy for any mount in this price class. The newer G11 from Losmandy, with the redisigned gears, is your best shot.

Otherwise, the Mountain MI-250 sounds like a good mount price-wise for what you are trying to do. Otherwise, you'd need something like a Tak EM-200, which is well out of your price range. You could look for either used.

Excellent results, all the more so because you are pushing the limits of your equipment pretty hard.

Moon

Posted By Ron Wodaski

Nice moon shot.

With respect to focus, your eye will usually get a sharper result on planets than the camera will, even with very short exposure times. the sseing gets in the way of those very small details.
