I used to be very active in the 80's. Used a 320mm f4 to prepare charts for Gregg Thomson, could get down to 15.5 mag from northern suburbs of Melbourne. Used Hyper 2415 and an OM1 for imaging.
Currently re-commissioning one of my scopes and was thinking of getting back into the harness.
What charts do you use? BAA... Thomson????
