Thanks guys for all the positive comments and warm welcome to the SDM club
John you are so right about Peter always trying to improve on the scopes. There were some nice suggestions made by Mark about how future SDM's could be further improved. I'm always looking forward to the next SDM getting built to see how it has evolved.
Sorry about the orientation of the pics! They were straight mobile upload, i've re-orientated them around the correct way. If the skies are clear this weekend i'll take some higher quality shots.
