Maybe not even that. :rolleyes: But gotta make do with what I've got. I've got some pretty big canons, I just can't mount em on anything. And the smaller pea shooting canons need new focusers, coma correctors and even new tubes. I'll get a round tooit one century. Or not. :question:

In the mean time... this target has been sitting on the hard drive since December 3/4 2013. I just got around to bothering with it. Rather than let it go to waste, thought I'd post it somewhere, so here it is. Unlucky you for seeing it. :P

Camera was a Pentax K-x, no filters, 45 x 2 minute subs for a total of 90 minutes, Skywatcher 120mm F5 achro refractor. Manual guiding, shot out of the kitchen window. ;) No really, it was.

Blue layer was desaturated to reduce the CA, green layer was murdered with HLVG and the red layer from sodium street lights was killed with Photoshop. That leaves um.... nothing? :question:

Sooo...when were you using my finder scope Kevin :question: wish I knew you were there, we could'a had a blast :thumbsup:

Nice capture of the region around M46, I wonder how many PN's are in that field?

Is it my computer? I see lots of dark trails like a spiders web all over the image:question:
Nice field though. :)

I think it was around the same time you were producing that magnificent image through the big main scope. You were probably too distracted to notice me. ;)



That's really in the image Ron unfortunately. The noise is primarily in the blue channel. I'll post a pic of that channel alone. It's caused from a number of factors. Mainly shooting DSO's with a DSLR with high ambient air temps and post processing artifacts. My Pentax K-x is terrible in the summer heat.
