A collection of large supernova remnants as a poster
Since I don't have any equipment to continue my imaging work, I have organized my image archives. This time I made an image collection out of the supernova remnants with a large angular scale. I'm trying to show here, how large they really are in the sky. There is an image of the Moon as a scale in the poster. The Moon has an angular diameter of about 30 arc minutes, that's equal to 0,5 degrees.

All images are in Mapped colors from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.

R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen. This is very close to a visual colors.

All the images are shot with the camera optics, Canon EF 200mm f1.8 monster lens full open, Baader narrowband filters (H-a, O-III and S-II) and the QHY9, a cooled astronomical camera with the KAF 8300 CCD chip. Very long exposure times are used, 15 to 50 hours per image, to reveal dim and diffused structures buried in the dense star fields. All images are guided with the Meade LX200 GPS 12" and the Lodestar guider. Meade works also an imaging platform for the camera lens.
In this collection, there are couple of very rare images, like Simeis 147, Sharpless 224. There are also two "firs light" images out of two super nova remnants, Sharpless 221(Sh2-221) and G65.3+5.7SNR. I haven't been able to find any other color images out of them, showing the whole SNR.

Exploded stars as an experimental 3d-stereopair
Images are for two different viewing methods, the first is for the Parallel Vision method and the second one for the Cross Vision method. Viewing instructions can be seen HERE.
Anaglyph versions, for the Red/Cyan glasses, can be found from my portfolio HERE.
NOTE! This is a personal vision about volumes and shapes, based on some known facts and an artistic impression.

INFO
Image shows two different ways to end a life of the star. At left, as a Supernova and at right as a Planetary Nebula. (Massive stars will go to a Supernova, after burning out all of the Hydrogen. There will be a Neutron star or a Black Hole left behind. Lighter stars, as our Sun, will turn to a Planetary Nebula, after ran out of Hydrogen. There is a core of the star left behind, it's called a White Dwarf and it will cool down gradually. )

Astroa Anarchy is looking for sponsors
Business corporate sponsors needed
I recently lost my imaging system due to massive short circuit. After calculating the repair cost of the current setup, it turned to be more expensive, than a new one would be.
I'm looking for Business Corporate sponsors to support my work as an astronomical photographer. I can offer lots of visibility in my pages. A free usage right to my photos is negotiable.
I have a plan for a new set up, the estimated cost will be around 25.000 Euros. (That's about 34.000$)
The new system will have a new telescope mount and the optics will be 14" SCT converted to a f2 astrograph, with the HyperStar system. (The price is low for a high end system, since I have lots of usable material from my old setup and I will do the actual labor by myself.)
How much visibility can be generated?
It's difficult to give any exact numbers, since I have Several channels to publish my images. My blog have had about 20.000 monthly visitors starting from the year 2007. My image portfolio have had about 15.000 monthly visitors, starting from the year 2010. Beside that, I have Facebook page for my photographs, it has about 1200 friends and about as many followers. Images get shared a lot by a popular Facebook pages.
Quite regularly my images get published by a very popular websites, like NASA Astronomy Picture of the Day or National Geographic, there is a collection of publishers logos at upper right corner of this page.
Any time the photo get published by a popular page, it will get easily millions of views.

All my images from the Spring season 2014
This is a small collection of my images, shot at Spring 2014. There are not many images and new ones aren't coming anytime soon, since my main telescope system has toasted beyond any repair. I'm having a hard time trying to figure out, how to restore my observatory to an imaging condition with a very limited assets.
I managed to get some really rare images though. I think, that both supernova remnant images, Sharpless 221 and G65.3+5.7 SNR, are the first three band color images, showing the whole remnant, in the world! If someone is able to find other images, I'm very interested to hear about it. Both SNR images are kind of long projects. Exposure time for the G65.3+5.7 SNR 38 hours and for the Sharpless 221 was 33 hours, with the planetary nebula Sharpless 216, 58 hours. (Image at the bottom of the poster.)
Main work for the season was the large, ten panels mosaic of the constellation Cepheus. Every pane is shot three times to have a narrow band color composition. Total exposure time was 92 hours, it includes shots from six different years.
All images from the Spring season -14 are shot with the Canon EF200mm f1.8 camera lens (full open), QHY9 a cooled astronomical camera and the Baader narrowband filters, H-a, S-II and O-III.
