IMPPG Software and Sunspot AR2993/94
I'm using IMPPG software for processing my solar images. See also this link for more information. It executes Lucy-Richardson deconvolution with great results.
So, after stacking my SER 16bit movies, I'm opening the Tif files in IMPPG. The result is a sharper and brighter Tif (or PNG,..) file which is finally edited using CS4.

Astroblog: The Lonely Photon
Two astro bloggers: Pascal (l) and Adriano (r) |
End of March I met in Berzieux (France) a new friend, Adriano, with the same intrest. Both stayed in the very dark skies of Berzieux making astropictures. It was a pleasure talking with him and to share tips and ideas. Interesting as well is that we both have a personal blog.
Adriano's blog can be found as The Lonely Photon - see this link.
Adriano has build up lot's of experience with installing his astro equipment on different locations as his own location suffers from lightpollution. This was clearly shown in Berzieux: remote, fast and efficient set up.
Lately he is taking pictures of nebulas and galaxies with long exposures (5-15hours) with some awesome results.

Coma Cluster Abell 1656
The Coma Cluster (Abell 1656) is a collection of galaxies (more then 1000 identified galaxies) located in constellation Coma Berenices. The brightest member in the central region of the Coma Cluster is Coma B (NGC4889 or C35) and about 300 million ly away from Earth.
Quasar CSO784 z=1.922
My picture of C35 (NGC4889 or Coma B) shows 3 quasars of which one is Quasar CSO784. CSO784 has a redshift of 1.922. Using Ned Wright's standard settings, the light of this quasar travelled 10.2 billion years.
