Mike,
It amazes me that at the age of 17 you had fashioned a chilled film camera, let alone been able to image M104 as well as you did!
It is incredible how far we've come in the last 30 years, not only in imaging technology but also scope technology. I look at the new GSO 16" RC scopes on an EQ8 as something that is now very much affordable. Even 5 years ago this would have been unthinkable for me! I wonder how many high powered telescopes are peering skywards each night in the world compared to 30 years ago? I hazard a guess that it would be several orders of magnitude!
Love the M104 comparison and the image of you in an "Adidas style" tracksuit top - 4 stripes versus 3! I think everyone had one in those days!
Cheers,
Mario
