Imaging in the weeds

As planned - I spent last night at the "secret location" intending on doing some long exposure astrophotography. All was well - the sky was clear, the equipment worked well, but the wind was an issue. Gusts up to 25 miles per hour ruined about 1.2 hours worth of exposures out of the 6.5 attempted.

My first target was Omega Centauri (NGC 5139) - a BIG beautiful globular Cluster. A challenge from my latitude as it never gets higher than 10 degrees off the horizon. I managed to get 2.1 hours of data on the bugger though.

Lastly, M20 and M8 - both in the field of the Takahshi E160 and the 5DII camera body but also never very high off the horizon. I was not happy with the results from my "one-shot" color system. The IR blocking filter and the bayer mask made the H2 regions look very blue and washed out. Sigh, I guess its time to consider something with a little more efficiency and red sensitivity.

Below are images of the observing site and my equipment as well as the final products for the evenings effort. Click on the images for a larger view.

Is that the zodiacal light in the 3rd pic from top?
