Eventually the clouds cleared the moon and this was the stage of the eclipse. I also remembered to focus for this one as I thought the blurriness of previous images were due to the clouds.
I found focusing hard with this one, probably because of all the murk we were shooting through and the seeing was crap too on top of that.
Here's hoping that the June eclipse is more favourable for us.
I didn't find focussing hard because for all shots prior to this run of 10 I had focussed initially on a boat and forgot to refocus when the moon became visible.
