Lunar Corona

Twas a dark, misty and cloudy night. Looks like the weather has turned again and that's put paid, for now, at least to imaging and viewing. However, the moon kept poking her head out through the clouds and the clouds were refracting into a corona, I thought it was a halo, but I've found that's not technically correct. I set the 450d on a tripod, using the 55-250 lens, adjust the FL till the corona nearly filled the frame in the shortest direction (vertical as I had the camera mounted in landscape). I set the Auto Exposure Bracket to +/- 2 Stops, adjust for a slightly blown centre image, and fired a sequence of 3. I then merged these to an HDR image and tweaked a little. This is the result.
