Compared to the old, borrowed CCD camera, which Kamil used for his
previous discoveries, the new G2CCD-1600 provides better sensitivity,
much less noise, bigger field of view, integrated filter wheel and
much faster image downloads. Smaller pixels ensures better image
sampling makes data reduction easier and more accurate.
Kamil Hornoch's 43rd nova found in the M31 galaxy is
marked by two lines The image above was processed by the “Subtract Median”
filter in the SIMS software package. Median filter eliminates any
image details smaller than the filter radius and keeps only the
large-scale background. On the other side, subtracting of the filtered
image from the original one eliminates the “nebulosity” and
keeps only small details, revealing stars from the bright galaxy core
to the dim outer regions.
The discovery image was exposed on October 25th, 2006 by
13.8 inch Newtonian telescope. Exposure time was
10 minutes (stacked from ten 1 minute
expositions).
