Swan 8 Hours

Shot this image 7/1/07 and 7/8.07. Skies were clear, but seeing and transparency were not so good. Just had to get out and image with my new setup. I'm using a Takahashi Sky 90 with reducer, SBIG ST-2000XMI with remote guide head, Astrodon Ha 6nm filter, piggybacked on 10" LX 200 GPS for tracking. I've imaged through the 10" in the past, but was itching to do some wide field stuff. Here are my first light images. This exposure is a total of 8 hours with 10 min subexposures through the Ha filter. Images dark subtracted, aligned and stacked in CCDSoft, processed in Photoshop. Click image for full size version.
