Image Information:

Date(s) May 22, 25, June 16, 17, 2006 (4 nights)

Optics Takahashi BRC-250 10 inch f/5 Ritchey-Chrétien astrograph with a 1,268 mm focal length

Mount Losmandy G-11 with Gemini Level 3 V 1.1

Camera SBIG ST-10XME

Guiding Internal selfguiding

Field Scale 1.10 arc seconds / pixel

FOV 40 x 27 arc minutes

Chip Temperature -15 C

Filter(s) SBIG standard RGBC in a CFW-8A

Location Shaver Lake, California 5610 feet at 37^o 04.33' N 119^o 20.33' W

Exposure(s) L = 12 X 1200, R = 7 x 600, G = 7 x 600, B = 8 x 600 (7 2/3 hours total)

Binning L = 1x1, RGB = 2x2

Camera control CCDSoft V 5.00.174

Processing software MaxIm DL V 4.53, Photoshop CS2 V 9.0

Image notes Heavy frosting took place on the CCD chip. The image has been cropped, but some of the frosting can be seen in the lower left corner. The desiccant in the ST-10XME was recharged half way through the luminance subframes.
