[NOTE: The seeing was quite good tonight, although the session was cut short by clouds. No heaters and no frost tonight. Setup on the 12" Meade LX200 was the Crayford focuser/f3.3 reducer/1.25" visual back/MX516 camera, and the images were all taken WITHOUT the IR blocking filter. Used flats from tonight and Jan 26 both, and darks and bias frames from 01/24/01, as I had left the setup the same. -GW]

NGC1496, an open cluster in Perseus, magnitude 9.6, diameter 6'. This was a 17-minute integration from one-minute frames, taken between 6:36 and 6:57 p.m. the evening of January 24. The frames were calibrated in MaxIm with darks, flats and bias frames, and the only enhancement was a contrast stretch.

NGC956, an open cluster in Andromeda, magnitude 8.9, diameter 8'. This was a 21-minute integration from one-minute frames, taken between 7:06 and 7:31 p.m. the evening of January 24. The frames were calibrated in MaxIm with darks, flats and bias frames, and the only enhancement was a contrast stretch.

NGC957, an open cluster in Perseus, magnitude 7.6, diameter 11', distance is 7,200 light years, and age is 15 million years. This was a 20-minute integration from one- minute frames, taken between 7:40 and 8:04 p.m. the evening of January 24. The frames were calibrated in MaxIm with darks, flats and bias frames, and the only enhancement was a contrast stretch.

NGC812, a galaxy in Andromeda, magnitude 11.2, 3'.2 x 1'.5, surface brightness is 14.3 mag/sq arcmin, and distance is 240 million light years. This was a 61-minute integration from one-minute frames, taken between 8:09 and 9:25 p.m. the evening of January 24. The frames were calibrated in MaxIm with darks, flats and bias frames. Then I applied a Digital Development filter (Kernel, low- pass), and finished with a contrast stretch.

NGC2304, an open cluster in Gemini, magnitude 10.0, diameter 5'. This was a 21-minute integration from one- minute frames, taken between 9:32 and 9:57 p.m. the evening of January 24. The frames were calibrated in MaxIm with darks, flats and bias frames, and the only enhancement was a contrast stretch.

NGC2266, an open cluster in Gemini, magnitude 9.5, diameter 6', distance is 11,000 light years. This was a 24-minute integration from one-minute frames, taken between 10:02 and 10:36 p.m. the evening of January 24. The frames were calibrated in MaxIm with darks, flats and bias frames, and the only enhancement was a contrast stretch.
