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.

Pickering's Triangle, my first light for the Autumn season 2015
This is my opening photo for the Autumn season 2015. I started this imaging project a year ago, at Autumn 2014. Back then I shot 12h of the light form an ionized oxygen, O-III. This is a two frame mosaic of the Veil Nebula supernova remnant. This Autumn I shot 5h of light from an ionized hydrogen, H-alpha. I was able to make a Hubble palette image by using the S-II from my older wide field photo of the Veil Nebula.

Colors are from the ionized elements, Hydrogen, Sulfur and Oxygen.
S-II = Red, H-alpha = Green and O-III = Blue.

"Howling Wolf" Nebula, vdB 149, vdB 150, LDN 1235 and PGG 67671
The second photo published from the Deep Sky West observatory. Lights are taken under a very dark skie. Unlike in my current light polluted location, it's now possible to image broadband targets, galaxies, reflection nebulae and dark nebulae! HERE is some more info about the Deep sky West Observatory.
I gave the nickname "Howling Wolf" after I saw the photo first time in my monitor. At the end of this blog post, there is an explanation for the nickname.

Rosette Nebula from a professional observatory in Tenerife
This is my second remote image this year but with different partner. I get contacted by Eric Recurt and we started a cooperation between us. The imaging season, up here 65N, hasn't started yet. This is a great way to produce high quality photos during my mandatory summer pause.

Something new! My first light from The Deep Sky West (DSW) remote observatory
The imaging season, up here 65N, hasn't start yet. I have had a wonderful opportunity to use couple of remote telescopes. One in Canary islands and the other in New Mexico. I'll publish more images from both telescopes soon.
The first photo published is from Deep Sky West observatory. It's taken under a very dark sky. Unlike in my current light polluted location, it's now possible to image broadband targets, like galaxies, reflection nebulae and dark nebulae! HERE is some more info about the Deep sky West Observatory
