After several abandoned attempts at trying to a get a set of subs for M 101, on my return from the fortnightly MKAS meeting I was able to complete the job at last after a troublefree session. With the volcano induced lack of aircraft it was a delight to see such an unblemished sky from horizon to horizon. The transparency was fairly good with a slight reddening in the subs but whether this was evidence of volcanic emissions would only be guessing. Details: 10" f4.3 Newt. 15x 10 minute exposures @ iso800 with CLS in DSS, CS2, Photobrush & XAT.
