Abell 1367 galaxy cluster in Leo

The first image where I carried out multiple re-focuses during the imaging session was with this image of Abell 1367, a galaxy cluster in Leo.  This image was taken on the night of Tuesday 4th March 2008 using the IDAS filter and 900-second subs.  Total exposure time 4 hours and 45-minutes, and I used the Robofocus to automatically refocus 3 times during the imaging session.  Noel has just had a quick process of this one whilst in the middle of sorting out all the images for Star Vistas.  Just as well as this looks like another one for the book to me 🙂
