Anaglyph 3D astro images and movies
PK 164+31.1, Start of the new project
PK 164+31.1, the "Headphone Nebula"
A false color H-alpha image of PK 164+31.1
I started a new project with this planetary nebula at January 22, the same nigh as I shot the IC 410.
This planetary locates in constellation Lynx. Magnitude is 14 but it has a very low surface brightness. The 16.8 magnitude central star can be barely seen in the image. Distance is about 1600 ly. This is a large object to a planetary nebula, dimensions are 6,7 x6,7 arcminutes. This object is not too commonly imaged.
Seeing was very poor at that night and I shot this target only to see if it can be captured at all. I shot H-alpha frames binned down 2x2, image scale is 1,5 arcseconds/pixel. I'll shoot more frames to this when weather allows and hopefully in better seeing. I have plans to expose O-III and S-II too to make a three band color image out of this target.
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Levels, curves and color combine in PS CS3
-
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO @ 8Hz
Image Scale, 1,5 arcseconds/pixel

Exposures:
H-alpha 7x1200s Binned 2x2
This exposure time is way too short for this low surface brightness object!

A Stereo animation
For those who has difficulties to see stereo pairs, there is a clever service in http://www.start3d.com/
It'll turn any stereopair to a smooth animated file.
Original 2D-image and details can be found HERE

IC 410 and IC 405 as a Zoomin Movie.
I have shot this area back in 2008 with a 300mm camera lens. In this movie the latest image of IC 410 is embeded in an older wide field image and animated to a still motion movie. By this way, I can show both, wide field and a high resolution in a same image.
Klick HERE to see this movie in YouTube, please, klick the HD-symbol at lower Right corner to see it in HD-resolution.
