Comet Linear 2000 WM1 on November 8, 2001

This image of comet 2000WM1 was obtained on November 8 (UTC), 2001 from Harrowsmith, Ontario with Cookbook 245 CCD camera on Celestron Ultima 8 f3.0 SCT. Only IR blocking filter was used. CBWinCam software was used for image acquisition and AIP4WIN for image processing.

Forty six images (120 sec. each) were taken between 00:12 UTC and 01:49 UTC. After calibration, images were median-combined. Then image was separately: a) rank-processed, b) Gaussian histogram-shaped and those two resulting images were averaged.

At that time comet Linear 2000WM1 was moving very slowly in front of Perseus Milky Way (East of d Persei) and median filtering was not very efficient in star-removal.

North is up.
