So here it is,
almost the end of 2015 and here is my collection of processed images
for the year. This is
more like a blog of imaging activities for the year. This is
being written in early December of 2015.
I started with Comet lovejoy in January.
All images taken with the following equipment:
Mount: Paramount ME
Camera: SBIG STL11000M
Filters: Baader LRGB Ha S2 O3 Hb
Comet Lovejoy appeared in January
of 2015 and I managed to get a nice shot of the comet by
a colourful pair of stars. A rare clear winter night in Bruce
This is an LRGB image with the pixels binned 3X3 and each channel 9
for a total exposure of 36 minutes. Collimation was off.
The Leo Trio of galaxies was
imaged last year in Luminance and I managed
to get some RGB data this spring. This LRGB is composed of
253 minutes of Luminance data and
combined with only 36 minutes each of the RGB channels
for a total exposure of 6 hours and one minute.
My next target was the nice
pair of galaxies, M81 and M82 in Ursa Major.
Again an LRGB image, exposure times were 145 minutes Luminance and RGB
45:45:39 minutes respectively. I would like to add some Hydrogen
Alpha data to
this image, but I'll have to wait until next spring.
My next target
was M106, which is a rather peculiar galaxy as you will see in a few
The center of this galaxy is in complete kaos. But first I imaged
in LRGB again
with 150 minutes of Luminance and 90 minutes each RGB. The colour
is somewhat anemic
and will require more data and processing. Some of the data was
acquired while the laptop
was shining brightly in the observatory and resulted in some nasty
Here is a
cropped shot of M106.
