CaK Full Disk 18th June

With temperatures up at 28c when I took this picture, the 40mm scope was all I was going to be able to use in the midday heat with the seeing conditions boiling away.  Fortunately this scope is impervious to all but the worst the atmosphere can throw at it, and, as a result I got a nice disk - 3 days in a row - surely a UK record 😆  Either way, at 500mm focal length and with the home brew CaK filter together with the PGR Chameleon 3 camera I got a nice full disk I thought!
