28 August, 2011. Combination of 20, 0.02 second images, using red, green and blue filters.
SBIG ST-10XE CCD. 20" f/6.8 Dall-Kirkham cassegrain with a 2x barlow lens.
On this night I was trying a new ST-10XE that had just been delivered. Comparing the results to the ST-8XE I think I prefer the ST-8XE, although the seeing was not as good on this night.
