This was the first light of my newly modified camera (cooled SC2). Darkframe contained absolutelly neither hot nor warm pixel. Because of low altitude of comet above horizon and city smog, I hardly saw M31 in my 15x50 binocular.Comet was not visible by naked eye. AVI file was captured and processed by K3CCDTools.
M32 is visible southwards from M31 and hint of M110 is north-westward from M31.

Comet visible by naked eye. AVI file was captured and processed by K3CCDTools (with flat field used). Because of strong processing hot pixels were not sufficiently eliminated. Speck on CCD chip was still present, but eliminated by using proper flat field.

Low position of comet above horizon, shining block of flats and soft clouds caused, that the result photo is worse than the above photo, although longer exposure was used.
AVI file was captured and processed by K3CCDTools (with flat field used).

Comet visible by naked eye. AVI file was captured and processed by K3CCDTools. For the first time, the flat field was used in K3CCDTools. Because of low number of frames (4), hot pixels were not sufficiently eliminated.

Sun was 23° below horizon. This was the first time, when I saw the comet by naked eyes.
AVI file was captured and processed by K3CCDTools. Unfortunately, some speck (on CCD chip) of circular shape is visible in the right part of picture (visible as dark circular spot).

Sun was almost 13° below horizon. The comet was easily visible in my 7x50 finder, but not visible by naked eye (urban location :-().
AVI file was captured and processed by K3CCDTools. All frames were aligned relative to comet. The stars trails reveal proper motion of comet!
Summed image was postprocessed in K3CCDTools. Vignetting on corners of frames was eliminated by creating artificial flat field frame in Corel PhotoPaint (by using radial fountain fill). The flat field was applied to each of 4 frames of mosaic (by using flat field frame as object with 'Hard Light' merge method). Brightness and color of result frames were adjusted to create the smooth mosaic. The mosaic is much more smooth than the mosaic from 8.3.2002.

Sun was almost 15° below horizon. The comet was visible in my 7x50 finder, but not visible by naked eye (urban location :-().
AVI file was captured and processed by K3CCDTools. All frames were aligned relative to comet. So during about 8 minutes of exposure the stars are visible. The stars trails reveal proper motion of comet!
Summed image was postprocessed in K3CCDTools by stretching histogram 1-100%, RGB balance and gamma factor 2.50.

Only 3 minutes after taking photo of comet's nucleus I started to capture comet's tail area.
Interesting thing was alignment. As tail in AVI frames was faint, the only available alignment point were stars. So at first I aligned frames relative to stars. Then I calculated length of star trails in photo above (shift in x, y). The shift I divided by number of frames. Then I calculated the result shift for 28 frames of tail area. I manually shifted these frames (all work was done in K3CCDTools).
The result of summation was postprocessed in K3CCDTools by stretching histogram 1-100%, RGB balance and gamma factor 1.70 (the sky above block of flats was brighter, so I could not afford to use gamma 2.50).
