An edge on galaxy, NGC4565, apparent scale in a sky





I have shot many targets with several focal lengths. 
Due that, I will publish some of my material as an image sets, with different field of view and detail levels.
The fractal nature of our universe stands out nicely by this way and it will make the orientation more easy.

Many times, it's difficult to understand the image scale of astronomical images.
Due that, I will add a Moon circle in some of the images to show the angular scale in a sky. 
The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.

I don't have too many galaxy images around, since I'm shooting from under a heavy light pollution .

Two images are used for the series above
  1. A gray scale image with a Canon EF 200mm f1.8@1.8 camera lens and the QHY9 cooled gray scale astronomical camera.
  2. A color image with a Meade LX200 GPS 12" and QHY8 cooled single shot color camera.

Images are in Natural color palette from the emission of ionized elements, R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.
NOTE. The size of the full Moon (0,5 degrees) is marked as scale.

Three images are used for the series.
First is a wide field shot with a Canon FD 200mm f2.8 camera lens.
Second image, is imaged with a Tokina AT-X 300mm f2.8.
Third image is done with a Meade LX200 GPS 12" reduced little under 2000mm.
Baader narrowband filter set was used with all images, wide field images was shot with a QHY8 and closeup with QHY9, both are cooled astronomical cameras.

Sh2-142, the "Wizard Nebula" reprocessed




Since my processing technique gets better and the time of year doesn't give any support for new images, I have reprocessed some older ones. There is now star colors added, other processing is tweaked too.


NGC 7380, the "Wizard Nebula", in Cepheus
Ra 22h 47m 0s Dec +58° 06′ 00″

Sh2-142 alias NGC 7380, in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

NGC 7380 is a catalog number of  the open star cluster inside Wizard nebula, SH2-142.
Nebula locates in constellation Cepheus, about 7000 light years from my home. 



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.

Original processing can be seen from here:


An experimental starless image to show some details in the actual nebula


Technical details:

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 @ 6,5Hz
Image Scale, 0,75 arcseconds/pixel
Exposures H-alpha 15x1200s, binned 1x1
S-II 1x1200s, binned 4x4
O-III 1x1200s, binned 4x4

I have used color data from an older, 2008,  wide field image of Sh2-142.

This is one of the most interesting looking structures in the sky!
NGC 7635 aka "Bubble Nebula, Sh2-162 or Caldwell11, is a Hydrogen emission nebula in constellation Cassiopeia. It locates near the open cluster M 52 at distance of about 11.000 light years from the Earth.
The bubble structure is created by a strong stellar wind, a radiation pressure, from massive hot magnitude 8,7 central star, SAO 20575, it can be seen in an image inside of the bubble, off centered at Right.
Bubble is an expanding shock front inside a giant molecular cloud and it has a diameter more than Six light years. The spherical formation is expanding at speed of 6500.000 km/h, due the huge scale and distance we can't see the movement easily. In a century, the bubble in this image will be only about one pixel wider, than now! ( ~1 arc second)Strong UV-radiation from a central star ionized elements in a gas and makes them glow at typical wavelength to each element. (Hydrogen glows Red light as Sulfur, Oxygen emits Green/Blue light at visible wavelengths)
