Messier galaxies, M81-M82, with integrated flux nebula
A new collaboration image with David Lane. Beside beeing a deep sky astrophotographer he is also a master of landscape astrophotographing, please, have a look at his homepage: http://www.davelaneastrophotography.com/
Image acquisition is made by David Lane. He sent a massive amount of data to me to process and here is the result, Messier galaxies 81 and 82 with a large amount of dim integrated flux nebula at front of them.
Total exposure time is around 40 hours with the William Optics GT81 telescope and SBIG STL-1100 3 CCD-camera.

Messier 31, M31, the Great Galaxy of Andromeda
Another collaboration image, this time with David Lane. He is also a master of landscape astrophotographing, please, have a look at his homepage: http://www.davelaneastrophotography.com/
Image acquisition is made by David Lane. He sent a massive amount of data to me to process and here is the first result, the Great Galaxy of Andromeda with 37 hours of exposure time.

INFO
The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 2.5 million light years from Earth. It is the nearest major galaxy to the Milky Way.
The Milky Way and Andromeda are expected to collide in 3.75 billion years, eventually merging to form a giant elliptical galaxy or perhaps a large disk galaxy.
At 3.4, the apparent magnitude of the Andromeda Galaxy is one of the brightest of any of the Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution. It has an apparent diameter of six times as wide as the full Moon
An experimental test
This funny looking image is just stretched vertically to try to show the actual round shape of the galaxy.
It looks like a barred spiral to me.

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

It's likely, that NGC300 and NGC55 forms a gravitationally bound pair.

NGC 55, irregular galaxy in constellation Sulptor
Note. Color balance edited 16.09.
NGC 55, barred irregular galaxy in constellation Sculptor. Distance about 7 million light years.
When I was stacking the Luminance channel of NGC55, I noticed two moving objects in a field.
I made animations of them to show the movement. It could be nice to know, what they are. When I'll find out,
I'll post the information here!

Something new!
FIRST LIGHT
for Northern Galactic members telescope
My first target was a M 104, the "Sombrero galaxy"
.jpg)
I have been a member of Northern Galactic astronomical group for some time now. Recently they have opened up a possibility for members to remote operate a great astronomical instrument in Australia.
This has been a wonderful opportunity for me to use a "never-ever-have-enough-money-for-it" instrument and secondly this is my first ever possibility to shoot from a dark location!
Technical details for M104 image:
Instrument information in an image.
Exposures
25x300s for the Luminance and 4x300s / RGB-channel
Only Dark frame calibrated, since Flats are not ready yet.
For me, it's very confusing to shoot from the Southern hemisphere, since the sky is rotating to wrong direction! Targets, and Sun, rice from West and go down to East. Beside that, constellations are new to me.
I'm all thrilled!
Special thanks to Bert Candusio for making this possible for me!

An experimental M101 Galaxy
Galaxy in "natural" color. Narrowband channels are mixed to match visible spectrum. Red=80% H-alpha+20% S-II, Green=O-III and Blue=80% O-III+20% H-alpha to compensate otherwise missing H-beta.
Galaxy in HST-palette, Red=S-II, Green=H-a and Blue=O-III
It's a Galaxy season but since my light pollution is so bad, I'm not able to do good broad band imaging, needed for targets like Glaxies.
I made this experiment to see, if it's possible to shoot Glaxy with NB-filters, there is some Broad band luminance used, it's shot with a Hutech light pollution filter.
Kind of interesting to see, how emission areas pop up visually, there was strongish signal in H-a and S-II,
O-III was weaker but there was couple of srong O-III regions, they are seen as Blue in a HST-palette image. There was some very weak O-III signal in a largish area around the Galaxy core, it can barely seen as a Bluish hue in the both images.

NGC4565
An other funny Galaxy shot from the night of 23.03.
This wide field precentation, with Canon EF 200mm f1.8 @1.8, shows lots
of Space around the NGC4565.
Waste of space?
Maybe, but I think this composition gives a feel about the dimensions of the Space.
The field of view is about five degrees wide.
-
Same equipments, than in previous post.
Exposures 7x150s. -
here is my previous image of the same galaxy, taken with a longer FL instrument.
Leo Trio
Image labeled with MaximDL planetarium
A grop from the center of the image.Not a bad resolution for a 200mm lens.
A Blink animation to show just Galxies.
-
I shot this one 23.03 for optical configuration calibration purposes.
The 200mm les is not a right tool for tiny glaxies, this is a sharp one though.
-
Image turned to be kind of nice, so I post it here.

Virgo Cluster of Galaxies
At the same nigh, than previous Sharpless target, I shot this beautiful Galaxy Cluster in Virgo. I needed a data for calibrating my QHY9 and Canon 200mm EF f1.8 optics orthogonality. I didn't wait much about image, since 200mm lens has litle bit too wide for galaxys. After all, it turned to be a nice image, so I post it here too.

M106, update
Now it's over here, nights are not astronomically dark anymore.
-
I managed to shoot 18.04. three more hours for M106.
The outer halo is now somehow more visble but massive light pollution, in my
location, eats out lots of it, IDAS LP filter helpped though..
_
I used longer subs, 1200s, for this secon tryout.
9 x 1200s = 3h
-
There is older subs, 8x900s from 17.04, combined to this new image,
so there is 5h total exposure time used.
-
Same setup, than in previous post.
-
I'm very pleased to functionality of SXV-AO active optics unit.
Becouset of AO, many details can be seen in the core of the M106 galaxy.
Processing was difficult doe the gradients coused by LP.
There is some deconvolution and wavelets used in processing
to bring out details more cleary.

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.
