Universe, rated by stars?
Just little something...
Rated universe, how many stars?
I used my image of a globular cluster NGC 6752 for the poster. Original image and technical details can be found HERE.

A starless Melotte 15 in IC 1805, the Heart Nebula
For some reason, I like to make starless versions of my astronomical images now and then. They'll show the actual nebula better and have a kind of mystique feel.
Human brains has a tendency to form some quasi logical shapes out of cloud of random dots, like stars in this case. Without stars, the shapes in a gas cloud stands out much better, I think.

INFO
The "Heart Nebula", IC1805 locates about 7500 light years away in constellation Cassiopeia. This is an emission nebula showing glow of ionized elements in a gas cloud and some darker dust lanes.
In a very center of the nebula, lays Melotte 15, it contains few very bright stars, nearly 50 times mass of our Sun, and many dim ones. The solar wind, a radiation pressure, from massive stars makes the gas twist to a various shapes.
Technical details

Dead Stars Society, a collection of passed away stars
I made a poster format presentation out of my photos of exploded stars. In this collection, there are two types of dead stars, Planetary Nebulae and Supernova remnants. Images are not in scale.
Individual images, with some information, can be found from my portfolio: http://astroanarchy.zenfolio.com/

New collection of my B&W images
I have a gray scale version from all of my astronomical images. The camera used, QHY9, is a cooled astronomical camera and it has a gray scale CCD-sensor. Color images are made by shooting the same target at least three times, with different filters. Three images are then combined to a RGB-color image.
Due to that, I have a gray scale version from every target. Usually the light emitted by ionized Hydrogen, H-alpha, has most details and I made a collection out of them.
A high resolution, gray scale, image collection in my portfolio, please have a look:
(Second folder from top left)
The Elephant's Trunk Nebula in IC 1396, more info and a color version in this blog post.
You can buy a photographic print from any image at first two folders in my portfolio, http://astroanarchy.zenfolio.com/
All prints will be real photographic prints on photo paper. For the most exclusive result, metallic paper can be used.
Metallic prints give a distinctive look to most color shots, black & white and sepia images are particularly effective. With its glossy finish and metallic appearance, it represents another dimension for creating images with exceptional interest and depth. Metallic paper adds stunning visual impact and a contemporary flair to photos.
