AR12645 in Calcium Light - 2nd April

The seeing was most definitely not in the favour of the larger apertures, but using the 100mm Tal100R refractor stopped down to 80mm using a Beloptik tri-band full aperture ERF, barlowing up to 3000mm focal length and using 2x2 binning on the PGR Chameleon 3 camera with a combination of lucky imaging meant I was able to get a closeup that I was reasonably happy with.  I quite pleased with the detail that has been pulled out in this shot.
