The Autumn season 2012
HAPPY NEW YEAR!
The year 2012 is about to end and the weather doesn't allow any imaging up here. In this blog post I'm publishing a collection of my new images from this Autumn season 2012.
A poster format collection of my images

HAPPY NEW YEAR!
And many thanks to all followers of Astro Anarchy blog.

The Best Astronomy Images of 2012 , Astro Anarchy gets published
The astronomer Phil Plait collected an annual list of the best astronomical images for the year 2012.
My special image of IC 1396 was selected to this list.

The ghost of Christmas past, IC 63
I shot new data for this object at the night of 24.12 to dig out some dimmer components. It was really freezing night, the temperature drops down to -24 centigrade (-11.2 Fahrenheit) and it was windy too.
IC 59 and IC 63

Colors are mapped to a HST-palette, R=Sulfur, G=Hydrogen and B=Oxygen

IC 59 and IC 63 at the distance of about 600 light years in the constellation Cassiopeia.
Image spans about 0,8 degrees vertically, that's about ten light years at its estimated distance.
IC 59 is at left edge of the image and IC 63 at middle. Nebulae are ionized from the ultraviolet radiation of hot, luminous star gamma Cas at upper right it locates only three to four light years from the nebulae.
Nebula is next to the Gamma Cassiopeiae, a bright, mag. 2.47, star in middle of the "W" asterism in constellation Cassiopeia.
Orientation in Cassiopeia
The area of interest can be seen at the middle of the image.

Image in visual colors
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. Click for a large image.
Variable Star of Mira Cet type

A variable star can be seen at center right, it's much brighter at 2010 image.

While I was combining data from 2010 to a new data, I noticed a difference between images.
There was a bright star in image from 02.10.2010, the same star in new image set from 24.12.2012 was much dimmer. I did use a Simbad astronomical database and it gave me a report of an variable star.

A detail from the Heart nebula
Have planned to shoot this detail for years. A pillar like formation at the North East corner of the IC 1805, the Heart Nebula. This is a very dim target, there is 8h of h-alpha emission captured and it's at a limit to be enough to show this object.

A two frame mosaic
This target was partly overlapping with my previous imaging project in IC 1805,
the Melotte 15, so I was able to build a two frame mosaic.
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

Guiding, SXV-AO, an active optics unit, and Lodestar guide camera 8Hz
Image Scale, ~0,8 arc-seconds/pixel
24 x 1200s exposures for the H-alpha, emission of ionized Hydrogen = 8h
Narrowband cahnnels for ionized Oxygen and Sulfur are taken from an older wide field image.
