OK, here comes
the good stuff. The summer was rather poor weatherwise
for imaging, but I got a number of good shots this fall.
All images taken with the following equipment:
Mount: Paramount ME
Camera: SBIG STL11000M
Filters: Baader LRGB Ha S2 O3 Hb
I added 60 minutes of Hydrogen
Alpha in place of the red channel and it really
made the red jets emanating from the center of the galaxy pop
out. I would love
to get some serious photons next spring and improve the outer areas of
This was the last shot of the spring and early summer.
I wanted to get some narrowband images next.
This is IC1396 otherwise known
as the Elephant Trunk Nebula.
I've always seen it as a flying saucer coming out of the clouds.
This is probably my first reasonable attempt at narrowband imaging
using Hydrogen Alpha, Oxygen 3 and Sulfur 2 filters. Each filter
allows only a very narrow specific range of the visible spectrum.
These are then assigned RGB colours and a colour image is created.
My next target was the Pacman
Nebula in narrowband.
I had imaged
the Rosette in Hydrogen Alpha when I first got the HNA 12 inch scope
some RGB data. This is also a favourite target for narrowband
imaging. I added 2 hours and 20 minutes
each of Oxygen and Sulfur data to the 150 minutes of Hydrogen I had
previously collected and mapped
the data to the "HubblePallette". I am really pleased with this
image but need to get the
blue haloes around the stars under control.
The last two images on this page are six channel images. I
combined RGB and narrowband data
to produce the lovely images below.
