IC 1340 project as a bi-color from hydrogen and oxygen
IC 1340, Part of the Eastern Veil Nebula in Cygnus
RA: 20h56m 45.8s DE:+31 degrees07' 17"
Colors are mixed R=H-a, G=O-III and B=O-III + 5%H-a
An experimental starless version to show the actual nebula better
An animation to show difference between H-alpha and O-III emissions
Hydrogen and the Oxygen are clearly separated
Orientation image
Area of interest is marked as a white rectangle in this older wide field image above.
Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Levels, curves and color combine in PS CS3.
Optics, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO, an active optics unit, and Lodestar guide camera
Image Scale, ~0,8 arc-seconds/pixel
16 x 1200s exposures for H-alpha emission = 5h 20min.
12 x 1200s exposures for O-III, emission of ionized oxygen = 4h
IC 1340 in Eastern Veil Nebula. Image shows a starless version of pure ionized Oxygen, exp. time ~5h.
This is a second version of this photograph. It looks like an electric version of the Nike statue!
Ps.
I made an animation about different components in my image.
In this animation, allthe components in my image of IC 1340 are separated.
Looks odd but it's very useful while processing the image, since operations can be done to single element in image without interfering other image components.
NOTE. There is absolutely zero data lost in this technique due to my processing method.
I'm using a "difference mapping" between images and all the removed components gets placed back byte by byte in final image!

First project, IC 1340, of Autumn 2012 continues
The weather hasn't been on my side. At four nights, I have managed to collect about three two hours set of Hydrogen alpha light exposures. Now there is more details and less noise, than in previous two hours version.
I'll shoot other channels, ionized Oxygen and Sulfur, for the color image, as soon as the weather cooperates again.

A closeup
IC 1340 is part of the Veil Nebula, a supernova remnant in constellation Cygnus at distance of about 1470 light years. This is one of the more luminous areas in this SNR. Image is B&W, since it shows only a light emitted by ionized Hydrogen. The shock front formed by the material ejected from giant explosion, the super nova, can be seen in this image.
There is only two hours of exposures integrated in this image. I'll need least three more hours for H-alpha and about a same amount for O-III and S-II to make a color composition out of this target.

My equipment
I'm shooting my astronomical images from downtown Oulu. This is my collection of gears needed for my astroimaging. Canon EF 200mm camera lens can't be seen in images here.
This is a new combination from old gears. Now I'm able to shoot with two cameras at ones! QHY9 is used for longer focal length work with my old Meade LX200 GPS 12" telescope at about f5. QHY8, a cooled single shot color imager, is used with Tokina AT- X 300mm camera lens for wide field work.
Now I can have both, a closeup and a wide filed images, from same target at same time. I'll test, if color information from QHY8 camera can be used with images taken by QHY9 camera.
As you can see, I don't have any fancy gears for my work.
Not a pretty boy...
Lots of cords. They might look unorganized but I can sure you, there is a system.
Light path from the telescope to camera. There is an active optics unit at middle. (SXV-AO)
Counterweight, Meade fork mount and the dew heater control box at right.
The other side of the scope.
The ugly yellow fabric, at top, works as an insulation for the
heater stripe at front of the QHY8 camera. It's heated due the frost.

First light for the Autumn season 2012, IC 1340
Finally the sky stayed open for couple of hours and I was able to capture some new photons for this imaging season. After a six months mandatory Summer pause, (I'm shooting from the latitude 65N) it feels like doing this at the first time.
For last couple of years, I have shot with camera lenses, Tokina AT-X 300mm f2.8 and Canon EF 200mm f1.8.
This season will shoot with much longer focal length by using my old Meade LX200 GPS 12" telescope.
I'm using the SXV-AO active optics unit with it and I have forced the f-number down to ~5 from original f10. (Focal reduction is done by "miss using " the Celestron f6.3 reducer.)
I'm a happy camper now!

New version, Cirrus of Cygnus
I made a new version out of this area in constellation Cygnus. This is one of my favorite images, there is something in this image but I can't really put my finger on it...

Tulip Nebula, Sh2-101, a study about the scale in a sky
This time
I'm zooming from 23 to 0,5 degrees of sky at the direction of the Tulip Nebula,
Sh2-101 in Cygnus.
I have shot many targets with several focal
lengths. Due to that, I will publish some of my
material as image sets, with a different field of view and level of details. The fractal
nature of our universe stands out nicely in this way and it will make the
orientation more easy.
Many times, it's difficult to understand the
image scale of astronomical images.
Therefore I
have added a "Moon circle" in the images to show the angular scale in
the sky. The full Moon has an angular size of ~30 arc minutes, that's equal to
~0,5 degrees.

Astro Anarchy, now in Facebook
I have opened a Facebook account, you are welcome to follow my addiction to astronomical imaging!
I will publish my new material here in my blog, as usual. In addition, I'll update my Facebook status regularly. My Facebook pages are not so much for personal information but they'll work as a publishing channel for my astronomical images.
I'll start to post new material in mid-September, when we'll have enough astronomical darkness.
Before that, I'll publish some of my experiments with older material.

Cygnus zoom in series, the "Crescent Nebula, NGC 6888
Due the high latitude, 65N, deep sky astronomical imaging can't be done up here yet.
Instead I made an other zoom in series from my older material to show the apparent scale in the sky.
This time I'm zooming from 23 to 0,3 degrees of sky at the direction of NGC 6888 in Cygnus.
I have shot many targets with several focal lengths.
Due that, I will publish some of my material as an image sets, with different field of view and level of details.
