Description

This is collection of 30, 1-min frames captured after a session of imaging M46. Realizing that this comet was close to being overhead, I looked up the coordinates and slewed the telescope there for a quick look. I still had a narrow band filter in place but did not want to stop to remove it. With this filter, the color of the comet is not accurate, so I have just posted the unprocessed raw images (monochrome). It's amazing how fast the comet was moving. Using the pixel locations in the first and last frames and the plate scale, I calculate 16.8 arcsec/min. The core of the comet is significantly elongated even after just one minute of exposure. I set the gain of the camera to its maximum value in SharpCap.
