First light with color for the Apogee U16M. FOV is ~4 x 4 deg. 3.55"/pixel taken at -25C with ambient at +12C with 71% power. Half moon up. City location. 6 nm Astrodon H-a, OIII and SII 50 mm dia filters.
Here is some additional information on the U16M.
At -25C, the average ADU for a bias frame is 1332. The average ADU in the same region for a 20 minute dark is 1338 for a net difference of 6 ADU. The range of read noise from Kodak for these CCDs is stated from 7-9 e-. This camera is listed at 9e-. The gain is 1.2.e-/count. The dark current at -22C is 0.04 e-/pixel/sec. The USB2 download time is ~16 sec. There are no column defects (Kodak specifies up to 4 with no two closer than 20 pixels). Thus, nearly all astronomical images will not be read-noise limited. In fact, the 6 ADU difference suggests that running the camera warmer will not impair S/N, which will be an advantage in hotter climates. Operating warmer will help with any residual image leftover from the lights in these full-frame Kodak CCDs. In short, this is a very quiet camera.
