For the recent transit of Venus I took my Takahashi FS-102 to work to share the event with fellow workers. Unfortunately my eyepiece case was up at my obsevatory near Anza with my main telescope. I was able to borrow an eyepiece on short notice but not a star diagonal. This made for some interesting contortions in viewing the transit. However in a way it was sort of a throw back to the original refracting telescopes before star diagonals were invented.
About 25 co-workers, all non-astronomers, were treated to views of the transit and with the expected WOWs we are used to hearing when we do public astronomy events. About a half dozen viewers used their i-phone or cameras to attempt eyepiece projection shots of the transit, with some amazingly good results. One viewer happened to take a shot during second contact and was able to record an image that showed evidence of the atmosphere of Venus.
