A panorama mosaic from the IC1396 to Sharpless 129
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 IC 1396, the "Elephant's Trunk Nebula" to the Sh2-129
In constellation Cepheus
There are two individual images used to make this panoramic image:
- IC 1396, http://astroanarchy.blogspot.com/2011/01/ic-1396-reprocessed.html
- Sharpless 129, http://astroanarchy.blogspot.com/2008/03/sh2-129.html
- some data from newer image of Sh2-129, http://astroanarchy.blogspot.com/2011/01/sh2-129-reprocessed.html
Technical details for the images above

Sh2-224 & Sh2-223
In this image, there is two supernova remnants!
Both are extremely faint. Exposure time was 15x1200s = 5 hours,
and in final image there was very litle information.
I wanted to try this difficult targe to see can it be imaged from the city center and
with QHY8 color camera. After tweaking the data about an hour, I was able to say, it can.
Image here is a false color image, H-alpha = Red.

NGC 4565
-
This beautiful edge-on galaxy, in constellation Coma Berenices, has a unbarred spiral structure.
Distance from our home planet is about 53 milijon light-years.
-
Transparency was poor, but seeing better than usually in my location.
Result from that, is tighter stars and some details can be seen in the galaxy disc.

Sh2-129, the scale in a sky, zoom in series
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 images to show the scale in a sky.
The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.
Sharpless 129
In constellation Cepheus
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.
NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.

Sh2-223, 224 and 225 lightened up
There was 15 x 1200s from 03.11.2008, I totally frogotten, that I had
shot them.

You can compare how additional Five hours of H-a hellped by looking two previous versions.
First, there is only Two hours of H-a:
Really bad looking and noisy,
Secondly there was 11 hours of H-a, looks much better:

This is a really dim Supernova Remnant pair, with fast, f1.8, optics
it has taken 16h of H-alpha light to get in this version.

M13, second tryout
Gropped area from M13. The extended exposuretime reveals more and more dim stars around
the core.
After I was shooting Sh2-240, I moved to M13.
This is a second tryout at this season.
Weather was ok to shoot with 200mm lens, but with2000mm situation was different.
Very bad seeing and since I shoot from very center of the city, there was lots of heat current from buildings.
M13 altitude was between 30 and 45degrees. Moust of the frames are shooted trough not so thin clouds.
This time I composed image so, that I was able to placea litle galaxy, NGC 6207, at the same field of view.
There is 5 x 10min and 11 x 5min, unfiltered subs used in the image.I allso add lights from previous tryout, 7 x 15min, IDA filter. Total exp. time is three and half hours.Camera: QHY8, telescope: LX200 GPS 12", Guiding: SXV-AO+LodeStar.
Image is scaled down
Ps.
The "Shadows and Highlights" tool under Photoshop is great for targets like this!
I can pull out dimmer stars as much as I like without blowing up the core.

The California Nebula, NGC1499
S-II, H-a and O-III composition, Hubble palette 
H-a+35%S-II, O-III and O-III+30%H-a, "Natural color" composition 
to better show actual nebulosity
-
-
This image looks very different, than images of California Nebula usually do.
There is two reasons.
First is, that this is a three color narrowband image, there is not
too many of them, least I haven't seen one.
Second reason is,
that image is "upside down" compared to usual precentation format.
I did this for a reason, narrowband composition reveals new structures in nebula,
they are very three dimensional and this position shows them best.

Narrow Band with UHC-s and H-alpha????
This is a very interesting test run!
I started to think, if I use UHC-s filter to capture colors to my H-alpha
luminens, what other information UHC filter might captured?
The UHC-S filter is a multi bandpass filter made so that only some portions of light in the visual the spectrum are transmitted. This UHC-S will pass a total of about 100 nanometers within the 400 to 700 nma range, with high percentages of transmission of that light in the portions of the spectrum commonly emitted by emission or diffuse nebula
Here is the spectral responce curve for the filter.
As you can see there is spike at about 500 nm containing both O-III and H-Beta, In singleshot camera those bands are ending up partly to Green and Blue channels!!!There is lots of H-alpha as well, but we are not interested about that, becouse we have separate 7nm H-a filter data. So this is a background and here are few samples what can be archived with that data.
This is a very first test run and there is lots of things to test, but it looks promicing so far.
All images have been taken with QHY8, a sigle shot cooled 6mb astro camera.
original H-alpha 16 x900s + 5 x 1800s light frames used.
Total exposuretime about 6,5 hours.
LX200 GPS 12" f6.3 + SXV-AO (Active Optics system) Elephants trunk nebula in IC 1396
This is pure RGB data with Baader UHC-filter 5x900s
Final RGB image, combined from previous images.
Lights: 5x1800s + 15x900s @H-alpha Color data: 5x900s UHC-s filter combined as HaR(Ha)GB
Hubble palette test from the same original data RGB > BRG and some color balancing
Modified palette test from the same original data
Here is the same method used for the Bubble nebula image
Original RGB data.
Exposure time is 4h for H-a and 2h with UHC-s filter for RGB.
HaR(Ha)GB image is combined from the data.
Modified Hubble palette from the same material as the original RGB
Palette variation from the same data
I hope, that someone else will test this method and report here about findings.
All comments and opinions are welcome.

Veil Nebula in O-III light
Veil Nebula with O-III filter only.-
This is a start of the new project.
I will shoot The Veil Nebula in two color narrowband,
where O-III is Blue and H-alpha is Red, Green will be
synthesized from Red and Blue.
-
Not a very good star though, at fist night (29.09.) I was able to shot
only three 20min. frames. Thats a way too litle for O-III light.
I'll shoot more , if weather up here ever permits it,
two more hours is needed here, I think.
-
In the final image O-III will be precented as Blue color.
Tokina 300 AT-X @ f2.8, is a very good lens for this target,
the field of view is perfect march for the Veil.

Here is an image where stars are removed,
it's interesting to see how far the O-III area really goes.

NGC6888, the "Crescent Nebula"
NGC6888 in Hubble palette 
"natural" color version 
H-alpha channel
I imagined the "Butterfly Neula" 29.09.2008.
At the time I left NGC6888 out of the field of view
to be able to better frame the Butterly nebula.
You can see part of the NGC6888 at lower right corner of the Butterly nebula image here:
-
At this time I wanted to capture the Crescent Nebula with the surraunding nebulosity.
NGC6888 is usually seen in longer focallenght images but I found wider field
as interesting doe the colorful and detailed nebula structure.

Butterfly Nebula, apparent scale in the sky
I have shot many targets with several focal lengths.
Due that, I will publish some images 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.
The "Butterfly Nebula"
In constellation Cygnus
Images are 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.
NOTE. The size of the full Moon (0,5 degrees) is marked as a gray circle in all of the images.
Images used in the series above
First image is a three panel mosaic of the "Cygnus Trio"
Second one is two panels from a mosaic.
Third is a one panel
fourth is a zoomed crob from the above image.
The mosaic wide field was shot with a Tokina AT-X 300mm f2.8 camera lens with a QHY8 astro camera and a Baader narrowband filter set

Sh2-155, The Cave Nebula
"natural" color version
H-alpha
Version with reduced stars
-
Last night I shot a new Sharpless catalog object, Sh2-155 in constellation Cepheus.
It's sometimes called the "Cave Nebula" doe the central formations shape,
I can't see the cave there though.
I shot three hours of H-alpha and one and half hours of O-III.
There is very litle of O-III there, but with extreme stretching of the data it was usable.
Image here is a narrowband color composition where H-alpha is Red and
O-III is Blue, Green color is synthesized from H-a and O-III channels.
There is three versions, first with "natural" colors and second with H-alpha only.
Third image is same color image but with reduced stars. The purpose of this image is
to show the nebulosity alone.

NGC 1499, the "California Nebula", reprocessed
Since my processing technique gets better and we don't have any astronomical darkness until mid September, I have reprocessed some older images. There is now better star colors and other processing is tweaked too.
NGC1499, the "California Nebula"
RA 04h 03m 18.00s Dec +36° 25′ 18.0"
Click for large images
NGC 1499, the "California Nebula" locates in constellation Perseus. Distance is about 1000 light years.
The nebula covers about 2,5 degrees of sky.
HST-palette composition from emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Narrowband data was used for Star colors, mixture of channels was the same as in "natural" color composition image below.
To see the size of this object (the apparent angular scale) in a sky, I have made some image series to demonstrate it. Please, have a look HERE.
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.
All the exposures, I have taken for this object, are used. Total exposure time is now about 20h together.
Two camera lenses was used to capture the data, a Tokina AT 300mm f2.8 and a Canon EF 200mm f1.8, both lenses was used at full aperture. Baader narrowband filter set was used, H-alpha, O-III and S-II
QHY8, cooled astronomical camera, was used with Tokina lens and a newer QHY9 with a Canon lens.
The original versions with imaging data:
and
As an addition, there is a longer focal length closeup image of NGC1499 used to boost details in mid section of the wide field image. Original post and details here: http://astroanarchy.blogspot.com/2010/12/ngc-1499-california-nebula-closeup.html
