I did a slideshow on the laptop. The slides looked real good except for the red nebulae in the Lagoon and Trifid nebulae. The red did show up a bit when I zoomed in at 100%. I guess I'm going to have to switch to digital sooner or later. But I think slides are fun for piggy-back work. What you see is what you get and nobody at the lab can mess them up. The authors of the "Backyard Astronomer's Guide" say that piggy-back astrophotography is film's last domain as far as astrophotography goes. Debbie
