M46 and NGC 2438 through Strongmanmike's finderscope ;-)

Maybe not even that.

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.

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.

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?

I reckon you should Fredify it now.

Sooo...when were you using my finder scope Kevin

wish I knew you were there, we could'a had a blast

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

Nice field though.

Cheers

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.
