Thanks David
I've played around a fair bit in the past with my Canon EOS 7D and 70-200mm f/4 IS lense experimenting with procedures and processing to achieve some reasonable APs... still a work in progress with much work still to be done.
Have recently acquired a GoTo mount and Orion ED80T so now have a whole lot more to learn...lol Tonights photos taken with my dslr attached to Orion scope... cheers!
