Wizard Nebula, NGC 7380
My new setup has a long focal length optics, Celestron EDGE 14", after years of shooting the wider field astronomical photos, it's very nice to dig in to the details of those cosmic wonders.
My new photo shows the Wizard nebula in Cepheus, I have shot this target many times with a various optical configurations. The combination of 14" telescope and large 12 micron pixels of my "new" second hand camera, Apogee Alta U9000M, delivers an optimal resolution to my seeing conditions (0.91 arcsecond/pixel). This makes possible to go very deep in relatively short cumulative exposure time, as can be seen in this photo. A dim background nebulosity stand out nicely after about six hours of H-alpha exposures.

INFO
NGC 7380, the Wizard Nebula, locates in constellation Cepheus at distance of about 8500 light years from us. The Nebula surrounds an open star cluster NGC 7380. Stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus).

NGC7380, the "Wizard Nebula" in natural colors, apparent scale in the 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.

Panoramic mosaic from the M52 & Bubble to Wizard Nebula
While making scale studies from various objects, I did make some new panoramas from archived images.
I will publish some of them as an individual images, comments and suggestions are welcome.
Panorama, from M52, Bubble Nebula & Sh2-157 to the Wizard Nebula
In constellation Cassiopeia
A panorama from the M52 to the Wizard Nebula in constellation Cassiopeia.
Image is in HST-palette from an emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
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. Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.This composition is very close to a visual spectrum.
Note. Size of the full Moon is marked as a gray circle, at lower Left corner, for a scale.
There are two individual images used to make this panoramic image:

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.

The Wizard Nebula reprocessed
I reprocessed this image since weather doesn't support imaging up here and my processing work flow is somehow different now. My new work flow produces much softer images, I think.

An experimental starless version of the Wizard nebula,
I like to make starless versions of my astronomical images now and then. They'll show the actual nebula better and have a kind of mystique feel.
Human brains has a tendency to form some quasi logical shapes out of cloud of random dots, like stars in this case. Without stars, the shapes in a gas cloud stands out much better.

A set of wide fields vs closeups
Since the weather doesn't support shooting any new material, I have done more image pairs from same target.
I have shot many targets with least two different focal lengths, usually a 200-300mm camera lens and my old Meade LX200 GPS 12" telescope. I have done earlier some scale studies as a zoom in series, with Moon circle as a scale.
Now I have done just simple image pairs, showing both, a wide field and a closeup from the same objects.
