Description

This is the last image shot from the 2012 WSP using the Officina Stellare RiLa400 astrograph. Acquired during 3 nights is a luminance only image of about 180 min. The three nights where been differents in terms of transparency and seeing but the final results is quite interesting. The processing is a little bit overdone to reveal all the faint structures presents in the data thus is a little bit noisy. I preferred to leave it as it is to show al the faint arms and structures. Hope You like it.

The image is presented 1:1 with a slight crop.

Imaged in February 2012 in the island of Marathon, Florida keys using an Officina Stellare RiLa 400mm f3.8 astrograph with a FLI Atlas focuser, an Astronomik Luminance filter and a FLI ML 11002 Camera on a Paramount ME. Guiding through a Borg refractor and a Starlight Xpress lodestar for about 180min.
