Reprocessed Supernova remnants




Since my processing technique gets better and weather doesn't give any support, I have reprocessed couple of older images. There is now star colors added and other processing is tweaked too.


Sh2-223, 224 & 225
This image is a very rare one. Two supernova remnants are visible in a same three degrees field of view.

Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.

Total exposure time is about 20h with a world fastest camera optics, Canon EF 200mm f1.8 with full aperture. 
A special processing technique of mine is used to process this extreme dim data:


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. 
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.

Original version with technical details:





Simeis 147 aka Sh2-250

My second reprocessed image is a Supernova remnant in constellation Taurus.
Original image of this very dim and large object was selected as an Astronomical Picture Of the Day, APOD, by NASA.

Happy new Year and clear skies to all!

My favorite image from last imaging season of 2010.

This closeup image of NGC 7000 is my opening image of the Autumn season 2010.

All my images from the Autumn/Summer season 2010



The year 2010 is about to end. 

Here is a collection from all of my astronomical images from Summer/Autumn season 2010.
I can't do any imaging from my observatory during Summer months, due the high latitude, 65N.
I was lucky enough to have an access to a Northern Galactic groups Australian remote telescope for few months this year.

Happy new year to all readers and followers!





The whole collection can be seen in my portfolio, with the technical details:








NGC7000 & the Pelican nebula as a Stereo Pair 3D



I have made animated 3D versions from most of the stereo pairs, they can be found here:
