Wednesday, December 9th, 2009
Another severely frigid night. We're not used to temps quite this cold here. But the camera seems to like it. I've had the least noisy images I've every worked with! This *really* makes me want to finish the Peltier Box with Richard. Tonight was 4 targets:
1) North American Nebula to add some Ha data to my RGB shot from sseveral months back.
2) M45 - this was mostly while I waited for target #3, but I wanted to see how the new camera performed on it as well.
3) Christmas Tree Cluster wide field (like some of the other's I've been hitting, this is a long awaited target).
4) B33 and IC 434 in Ha to add data to my previous shot. (next to the Ha shot below)

Addendum - Added more tagets the following night - image details to come:
5) IC443 - Jellyfish nebula
6) IC1396 - Elephant Trunk
7) IC410 - Tadpole nebula

I got everything though perhaps a little less of everything then I wanted - except for M45.. Doh! I got three hours of that thing. It's a cool object anyway... so... it adds some different color to what I've been posting.

The North American and Pelican Image in Ha
This object is not an ideal target as it's setting in the west pretty early, but if I can catch it right at the beginning I can get it. So I went for it and managed to pop off 40 minutes (2 frames!) before it set into my trees. Unfortunately, 50% of the frames had satellites in them... Doh!

The North American and Pelican Image in HaRGB
So I took the Ha data and combined it with the RGB data I journaled on July 21, 2009. I can't say enough about how cool it is to enhance these RGB shots with Ha data.

The Pleiades M45 Image
This was more of a test and a wait for what I really want to rise. It turned out decent. I can likely process it better. Since I don't have current flats, I used GradientXTerminator to clean up the vignetting and it wiped out most of the outer nebulosity. Doh!

The Christmas Tree Cluster and Cone Nebula Image in Ha
Oh man! I am so stoked to be able to shoot this. I didn't want to take it across the meridian, so I ended up with 2 hours 20 minutes on it. But man... after seeing how faint it is I probably should have taken more. I think the better shots I've seen are closer to 6 hours. I don't know the name of the dark region.

IC1396 Elephant Trunk Image in Ha
In wanting to find grand, large, Ha targets for which I have matching RGB data, I shot IC1396 for 3 hours.

IC1396 Elephant Trunk Image in HaRGB
This is the HaRGB combine. 5 hours total. The color data was taken through a WO MegRez 90 at the Oregon Star Party in 2009. The Ha data was taken from my house before the moon rose.

Thanks guys. I have RGB data on only two of the targets right now. NGC7000 and IC1396.

I might get a chance to get RGB data on the other targets, but the clear skies are gone for now... waaaaaa...
