M1, the "Crab Nebula" as an animated 3D-image
In this blog, there is lots of experimental material. To see my actual astroimages, please, see my Portfolio: http://astroanarchy.zenfolio.com/ 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!
Original Image with details can be found HERE
M1, the "Crab Nebula" as a 3D-anaglyph (Red/Cyan)
You'll need Red/Cyan Eyeglasses to be able to see this image right. Note, if you have a Red and Green filters, you can use them! Red goes to Left eye.
NOTE! This is a personal vision about forms and shapes, based on some known facts and artistic impression
NGC 2175 & Sh2-252, the "Monkey head nebula" in HST-palette
Nebula in HST-palette, Red=S-II, Green=H-a and Blue=O-III
I managed to get the S-III channel information last night, just two 20min. frames.
That was enough to build the HST-palette image.
Technival details in previous post:
2 x 1200s S-II binned 2x2 added to a previous data.

NGC 2175 and Sh2-252, the "Monkey head nebula"
Nebula in natural color, composed from two narrowband channel, O-III & H-alpha.
There was some clear skys last night, so I was able to start a new project. this time my target is an open cluster, NGC 2175, it's surraunded by an emission nebula Sh2-252, it's sometimes called as a "Monkey head nebula".
NGC 2175 locates in constellation Orion. In my northern location, 65N, this target is not very high, about 40 degrees in maximum elevation. Distance from Oulu is about 6350 light years.
My original target was M1, the Crab Nebula but due the poor seeing i pick this secondary target. M1 needs a good seeing to be imaged well.
The nick name "Monkey head" is well deserved!
Processing work flow:
Image acquisition, MaxiDL v5.07.

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 @ 3Hz
Image Scale, 0,75 arcseconds/pixel
Exposures H-alpha 7x1200s, binned 1x1

I'll shoot the S-II channel later, when ever weather let me do so, for this target.
