This is an 8-pane mosaic with initial dimensions 10675X7384px.
From the beginning I had multiple problems with the lens due to flexure but fortunately they were solved with the help of a good friend (Aggelos Kechagias-
http://pegasusastro.com/).
Unfortunately there was no time to start over..so I am stuck with some problems with my stars.
So....in the nick of time.....still hope u like it.
