M27 at higher magnification

Posted By Enrico Africa

Nice, Tyler! As far as going at higher focal lengths, check out my "Mewlon won't come to focus..." thread. With an AO-7, I think you'll be able to rock and roll at the CN's native resolution and your G-11.

ngc 7008 platenary nebula in Cygnus

Posted By Enrico Africa

Very nice, Larry! The stars seem a little out of round, though. Tracking? Collimation? Overall, a nice result. Bring on the Mewlons! 8)

Excellent image, Jim! Are you keeping the Artemis?

M13 wide field deep sky

Posted By Enrico Africa

Very nice, Roland! Two 10-minute subs? Not much in the way of blooming! Did you use the 0.67 Telecompressor?

A Better Bubble

Posted By Enrico Africa

Dan,

This is a very, very nice, richly detailed Bubble. I see a bit of an artifact around the bright star, though. Is that a blooming-repair artifact? Not to detract from the beauty of the image, however!

Cacoon

Posted By Enrico Africa

Brian,

That's a different version of the Cocoon. Pretty cool-looking! How did you get your Mewlon down to f/8?

Deer Lick Group

Very nice, Joe. You captured detail almost all the way to the core. This is a difficult target to image, and you captured it well (you must have been up late wink !)

In the spirit of encouraging the philosophy of this group to give constructive critiques, with a critical eye I see where the faint outer regions of the galaxy and its companions have a somewhat grainy appearance. I'm not expert at this yet (my galaxies share a similar trait!). The suggestions I hear about (and have not yet been able to apply without imparting an artificial appearance to my image) would be to apply a bit of Gaussian blurring to those dimmer regions. I'd love to hear other suggestions as well.

The Veil, SXV-H9

Posted By Enrico Africa

That's a very promising image, Ralph! Looking forward to a deeper image. I'm curious about the green glow around the star - is that an internal reflection, a processing artifact, or....? Be thankful you have an ABG camera! My camera is NABG, which is part of the reason I have not tried this object yet!
