Awesome Michael! that was a wonderful time in the earlier days of my astrophotgraphy journey, thoroughly enjoyed the whole event
I had just left yr12 in Canberra at the time and I have a photo I took on that same day (19/20 march) and at the same position, with a Pentax 6X7 camera and 300mm F4 lens
19/20 March 1986
The tail was huge at that stage
