OBJECT DESCRIPTION AND IMAGE SESSION
Caroline Herschel discovered this clusters on February 26 1763 and included in her list as number 2. This cluster was her first original discovery of a deepsky object. Her brother William included it in his catalog. The cluster contains roughly 80 stars, mostly of them relatively faint.
This is the first test of the AT RC 8" f8 Telescope. I did not take any flats and the raw files had several dust donuts neutralized in the processing. The first attempt in off axis guiding, with Telescope Service Thin Off Axis Guider
