Date: August 7, 2004
Exposure: RGB 30:30:60 - 15 x 120s R; 15x 120s G; 15 x 240s B
Processing: CCDSoftV5 for image acquisition. MaxIm for guiding and image alignment, calibration and color combine. Photoshop CS for processing and jpg conversion)
Conditions: Average, shooting between the clouds
Scope: Ap180EDT @ f/7.4
Camera: ST-10XME, -15°, AP 0.67 Focal Reducer
Comments: Thought the conditions were going bad and then the sky cleared and the atmosphere settled down a bit. The temp stabilized at 57°F so I focused both the guidescope and main scope, started Sequencer 3 and went to bed. Got up and was pleasently surprised that the temp held steady and the focus was good on all frames.
