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

Just next to Sh2-221 locates a closest known planetary nebula, Sh2-216. This is also a very rarely images target, due to its low surface brightness and large angular dimension. This mosaic image covers over seven degrees of sky vertically. (The Moon has an apparent dimension of 0.5 degrees.)  Mosaic is made out of my new data of Sh2-221 and an older material of Sh2-216. Some new exposures was taken for the Sh2-216 to match the background for a mosaic image. 

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 repairI'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.

A zoom in series of the Sharpless 132



Now and then I have published some zoom in series of various objects imaged by me.
The purpose is to show the apparent scale in the sky. Beside that, this series shows nicely the fractal nature of our universe.  Series are possible to make, since I have shot many objects with various focal lengths.
Like this one is shot with 200mm, 300mm and ~2000mm  focal lengths. Images are from my large mosaic image of the constellation Cepheus.

Note. A circle, size of the Moon, in the images as a scale. (An apparent scale of the Moon is 0,5 degrees, or 30  arc minutes.)

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

A poster format collection from the Cepheus project



In this collection of my images, the objects shown in a large mosaic of the constellation Cepheus, are collected together. There are indicator lines to show the actual location of object in a large context. As can be seen, I have shot many objects in various focal lengths.

 The Cepheus project was my last published image before the major break down of my imaging equipment.

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