All of my images from the Autumn season 2013
This season was kind of unlucky to me. I planned to shoot longer focal length images at this Autumn with my 12" Meade. Unfortunately there was serious technical problems with my gears and I was forced to move to a wide field instrumentation. All this took lots of time and top of that, the weather up here, 65N, wasn't very supportive. My main work for the autumn season 2013was a rarely imaged supernova remnant in Cygnus known as G65.3+5.7SNR
A collection of my images from the Autumn season 2013 as a poster.

Some new experimental work
I made a series of artworks out of my astronomical images by flipping and rotating the image. Every picture is made out of the single astronomical image of mine. The result shows the Nebula at many different orientation simultaneously. All my experiments can be found from my PORTFOLIO Do you recognized what has been the original astronomical object?
Vision XII, from the series Visions of Space
This is one of my artworks based on an original astronomical photograph shot by me.
Image belongs to a large series of images called Visions of Space.
Note. Image is manipulated but all the elements in it are from a real astronomical object.
Some publications
I got my sixth NASA APOD (Astronomy Picture of the Day)
I have made several 3D-studies out of my astronomical images. Couple of my animations gets widely published, here are few samples:
- BuzzFeed, my image is a number 26.

3D-studies of the Veil Nebula supernova remnant
The weather doesn't support the imaging of the new material, so I made a collection of an experimental 3D-studies out of the Veil nebula SNR. Some of the images are new but couple of them are published earlier.
Images are for two different viewing methods, the first set of images is for the Parallel Vision method and the second set for the Cross Vision method. Viewing instructions can be seen HERE.

A start of the new project, Cepheus mosaic part1
I'm about to make a similar mosaic out of constellation Cepheus, than I made out of constellation Cygnus.
The first part is ready now. It's a four panel mosaic showing two main objects, IC 1396 and the Sharpless 129 (Sh2-129). I managed to get visible an extremely dim planetary nebula candidate, OU4, inside the Sharpless 129.

At this first part of the Cepheus mosaic, there are four individual panels stitched together. At lower right corner, there is the Sharpless object 129 (Sh2-129). The blueish area, inside Sh2-129, is a recently found plaentary nebula candidate, OU4. The famous astrophotographer, Nicolas Outters, has made this discovery, HERE is a paper about it. OU4 is an extremely dim formation. 11h of O-III light with very fast Canon 200mm EF f1.8 camera lens, was needed to have some hint about it.
I will continue this project, as soon as weather allows. The final mosaic will be 10-14 panels larg

An other supernova remnant in Cygnus, G65.3+5.7 SNR
This is a rarely imaged target. I haven't been able to find an other color image of it, showing the whole supernova remnant. This is also one of the most difficult targets, I have ever shot. Due to very dense star field, large angular dimension and a very diffused structure this is even more difficult target, than a Simeis 147 supernova remnant in Taurus. Total exposure time of 32h was needed to have this kind of "thin" image.
G65.3+5.7 SNR has about the same angular dimensions, than brighter and more famous remnant in Cygnus, the Veil Nebula. The angular dimensions are about 3x4 degrees.
NOTE, this image is updated at 20.01.2014. There is now a better H-a channel and the background is practically full of ionized Hydrogen, H-alpha.

Veil Nebula unveiled
The exhibition is over, lots of visitors and many photographic prints has been sold.
Many thanks to all visitors and buyers!
I have some new material waiting for publishing, even though the weather has been really bad up here.
I had some technical problems with my longer focal length instrumentation and I had to move back to use my wide field tools. Veil Nebula in this post has been shot with the Canon EF 200mm f1.8 camera optics.
There is now 13h h-alpha light, collected from years 2008, 2012 and 2013.

Info
Veil Nebula is a cloud of ionized gas and dust, leftovers from an exploded star. The star went off some 5000-8000 years ago at distance of about 1470 light years. This, relatively faint target, is difficult to image due to the large angular diameter, about three degrees, and a dense star field.
This is a second version of this object, older version can be seen Here.

There are not too many images around about this little fellow.
Sharpless 106, the Hourglass Nebula, locates in constellation Cygnus approximately at distance of 2000 light years. This is kind of a small object, an apparent size is about four arc minutes (Moon is about 30 arc minutes.) There is a young star at the center of the nebula, S106IR. The solar vind, a radiation pressure, from the young star is responsible for the gas cloud's hourglass like shape.
I think, there is a hint of the outer shock front visible in my image. It locates symmetrically at both side of the central nebula .
