Monday, July 7th, 2008
Unlike last night tonight was clear and mostly free from haze. It just so happened that another airplane passed with its headlights on and I could see a little haze in the light, but not nearly as much as last night.

There were more stars to be seen as well as the Milky Way and M31. I'd say the limiting naked eye magnitude was closer to 5 or so.
 
Took three more pictures tonight. The North Americal Nebula (again) trying to improve on last nights shot, M27 and M33.

Screenshot
For this gallery I'm also including a screenshot of the workflow on the laptop during this session. The picture shows PHD Guidings graph which shows that the quality of the tracking is pretty good for not being a super high end mount and in the background you can see the captured image of M27 with near perfectly round, very tight stars after taking a 3 minute exposure.
See Gallery below for image
 
North American Nebula
With the seeing much better tonight (though still not perfect by any stretch) I thought I'd tryfor a better shot of NGC 7000 the North American Nebula. This one turned out better then the last one for sure. Slightly more detail, more color in the nebula and not as much fuzz overall.

Scope: William Optics MegRez 90mm @ f/5.5 w/WO-FLAT-III 0.8x Focal Reducer
Mount: Orion Sirius EQ-G with GoTo
Guiding:  Meade DSI Pro and PHD Guiding
Camera: Canon EOS 350 Digital Rebel XT (unmodified)
Special Settings: None
ISO: 1600
Exposure: 1 hour 18 minutes - 26 @ 180 seconds
Processing Software: Acquired in Nebulosity, Stacked in Deep Sky Stacker, Levels and Curves in Photoshop
See Gallery below for image

M33
M33 was rising just as I was thinking about heading in (about 2:30am) so I shot an hour of it before settling down for the night. Not bad at all for an hour. I'm very pleased with this shot.

M27
M27 had flipped on the meridian and was near the zenith so I shot an hour of it while it was in a dark part of the sky. This is the longest exposure of M27 I've taken and the result is excellent for my images. It's pretty small for my focal length, so I tried using a 3x Drizzle in Deep Sky Stacker on this one. It work beautifully.
