Opening image of the Autumn season 2010
Close up of the NGC 7000, the "North America" nebula.
Image is composed from O-III and H-a narrowband channels to a bi-color image.
This palette is close to a visiblel spectrum.
Last night we had about three hours of astronomical darkness, up here 65N.
I'll shoot more H-alpha and the S-III channel later.
An experimental starless version to show the actual nebula
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations.
Levels, curves and color combine in PS CS3.
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 6Hz
Image Scale, 0,75 arcseconds/pixel
Exposures H-alpha 7x1200s, binned 1x1
O-III 1x1200s binned 3x3
Notes.
I had some problems with the camera orthogonality. Due that, stars at to and bottom are stretched.
I'll re shoot this material again after I have fixed the problem.

Galaxy NGC 613
NGC 613, barred spiral galaxy in southern constellation Sculptor.
Distance is about 65 million light years. Image is a broadband LRGB-composition.
This target has a smallish angular diameter, about 5,5' x 4,2'. I might try this one again with a better seeing, at this time seeing was about 3,5" FWHM.
The telescope:
Close up
Technical details:
16" RCOS ja Apogee U9000 camera.
LRGB combo.
9x600s for the Luminance and 1x600s / RGB-channel . Dark and Flat calibrated.
Raw data is shared by Petri Kehusmaa and J-P Metsavainio
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.

A collection of astronomical movies from my images
All movies are published before in this blog. There has been very few viewers for them though, so I think reposting might be a good idea.

THE MOON
All Moon movies are made by re-projecting 2D-Moon image to a sphere. After that, the observation location can be freely selected, as long the area of interest stay on the visible area. I like this technique a lot, since the original image stays unprocessed!
Experimental Moon movies:

(There is a movie of Andromeda galaxy as well)

The "Bug Nebula", NGC6302 as an animation
The animation is made by splitting the original 2D-image to a layers by the image content. Layers are then taken to a 3D-modeling software, "TrueSpace", and projected to a 3D-surfaces and animated to a movie file.
Stars are placed to Z-axel by apparent brightness , brighter ones are closer.
Original images and imaging details can be found here:

Images from the NG members remote Australian telescope, 06.05 - 21.07.2010
Here is a small slideshow about all the images taken with the Northern Galactic members remote telescope, 16"RCOS, in Australia between 06.05 and 21.07.2010
Image of the instrumentation can be seen HERE.
All my astronomical images, normal and some experimental 3D work, can be found from my portfolio:

IC 5150, a Planetary Nebula
IC 5150, a Planetary Nebula in constellation Grus.
This rarely imaged southern planetary is dimmish, magnitude about 12. Due the full Moon, it's imaged with narrow band filters. Only H-a and O-III are used to compose the natural bi-color version.
This object will be better imaged with a broad band LRGB, since it emits some strongish continuous spectrum but as mentioned, the full Moon prevent me to do so.
I haven't seen any narrow band color images of this earlier!
The telescope and technical information:
16" RCOS ja Apogee U9000 camera.
LRGB combo.
H-alpha 3x1200s, Dark and artificial Flat calibrated.
O-III 3x1200s, Dark and artificial Flat calibrated.
Raw data is shared with "Team Finland"
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Levels, curves and color combine in PS CS3.

NGC 6302, the "Bug Nebula"
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission.
This composition is very close to a visual spectrum.
HST-palette from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen
NGC 6302, the "Bug Nebula", (also called the "Butterfly Nebula") is a bipolar planetary nebula in the constellation Scorpius. The central star is one of the hottest of its kind, about 200.000 K. The central star can't be seen due the dense equatorial disc composed of gas and dust. The disc might be the reason for the bipolar structure of this bright planetary nebula Distance is about 3500 light years.
The telescope and technical information:
16" RCOS ja Apogee U9000 camera.
LRGB combo.
H-alpha 5x1200s, Dark and artificial Flat calibrated.
1xO-III 1200s, Dark and artificial Flat calibrated.

NGC 6302, the "Bug Nebula" as an animation
Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.
Please, let the images load for few seconds to see them animated!
