M57, the "Ring Nebula", project finalized
The halo was clear in H-alpha channel and there was some hints of it in luminance one.
Ring Nebula, M57, NGC 6822, locates in constellation Lyra, near a very bright star Vega. This planetary nebula lays about 2300 light years away from the Earth and has a diameter of 1,3 light years.
The small angular diameter, 230" x 230", makes this target difficult to image. The central white dwarf of planetary nebula nucleus is seen in an image as a Bluish dim star, visual magnitude is 15,75. Star was visible only in O-III channel and luminance channel.

3D-study of NGC 300 galaxy
An experiment with the NGC 300. All the stars from our milky way are removed and the original 2D-galaxy image is the projected to a 3D-surface. The resulting 3D-model is animated to a movie file. The purpose is to show the actual shape of the galaxy, now distorted by a perspective.
