Thanks Jeremy,

I lot of development of new techniques not least of which is to find Mercury in bright daylight with a Dobsonian with the help of my Argo Navis digital setting circles. External shield to block the sun from heating the inside of the tube worked well too.

Processing methods very different for Mercury compared to other planets- this image was the output of the best 1% from 333k frames.

Best wishes

Martin
