version of NGC 7331 to my site. I was going to zoom in closer but the two
negatives that I needed were a tiny bit soft because I thought I did not
need to refocus from the previous night (ha-ha-ha!!!)

hypered Royal Gold 200, both 75 minute exposures at f/8 with the Cassegrain.
I processed the files to show as much faint stuff as possible but also to
keep detail down to the core... you can see the arms spiralling in like a
snail. I LIKE this film...!!!
