ST9XE CCD Camera Eyepiece Projection @ f/55

Integration Times: RRGB Images

RED (RG610 Red Filter, 610-1100nm: NO IR Rejection) 0.14-0.15s 2-3 images

GREEN (CFW8C, 531nm central; BWHM 86nm) 0.55s 4 images

BLUE (CFW8C, 450nm central, BWHM 116nm) 2.20s 6-7 images

Images bias,flat and dark corrected.

 

Seeing good (7 Pickering) but high winds (NE, 4-11 kts). Transparency = 4.5m .

Altitude = 57-58 degrees. No dew.

 

NP Hood bright and large both visually and on CCD images. Light terminator haze. Cerberus-Trivium remains weak.
