NGC7380 in H-a

Posted By Thomas V Davis
It's not the best, but I have always found this object to be very difficult to process. The "waves" are cool, but the faint edges really challenge processing.

M38 and NGC1907; Auriga

Posted By Thomas V Davis
Well, while I'm waiting for my other scope to get fixed I decided to shoot with the AP155. This is the first of two images that I've been working on. I think I shot each frame for too long since the star colors are too white (each frame was 180 sec). Oh well. I did start to pick up some faint emission nebulosity however. This would be a great region to re-explore with a larger, faster scope.

NGC6946 and NGC6939

Here are a couple of favorite targets in Cygnus and Cepheus. They make a pretty pair. Details at link:

M38 and NGC1907 -- Better color and sparkle

Posted By Thomas V Davis
I reprocessed M38. After a little of this, and a little of that I came up with this "better color and sparkle" version. As for the spikes....just image your looking through a big Dob!!

My first M42 of the year

Posted By Thomas V Davis
Here is my first attempt at M42 this year. I need to add more data to get better SN ratio and cut down the noise in the faint "brown" portions of the nebula. Also, I need some shorter exposures for better core detail. Maybe I'll rotate the camera? Maybe try a mosaic? I don't know yet. It's early in the year and not as cold as when I usually try to image this one. Still, not a bad start I think..............

Cocoon - old data, new processing

Posted By Thomas V Davis
WIth all the excellent images of the Cocoon Nebula lately (Jim and James) I decided to revisit my data from last year. The weather has been cloudy so it gives me practice on data manipulation. Anyway, here is my version of the Cocoon after a re-processing run with some different techniques.

NGC1499 midportion in H-alpha

Posted By Thomas V Davis
I had a few minutes before a weather front came in last night so I thought I'd get some H-a data on this.

IC59 and 63; Cassiopeia

Posted By Thomas V Davis
Here's a couple of real faint nebulae. Gamma Cassiopeia makes this region a processing challenge.

IC443 -- framing messed up

Posted By Thomas V Davis
I messed up the framing on this one so I'm starting over. I did, however, process the data anyway.

IC443 Supernova Remnant in Gemini HaRGB

Posted By Thomas V Davis
Here is the "finished" version of my IC443 in Gemini. I had a little interloper during the RGB exposure. This asteroid has been cataloged before unfortunately. Tough processing due to Eta Gemini and it's glare. Anyway, tell me what you think.
