Notes:

Lots of evenings with fog lately ... The first two nights imaging M 88 were cut short at 4 and 8 subs ... That is why it took five nights to complete.

See here for a 1991 image with Supernova 1999c1 (arrowed), taken with the 14.5" f5 Newtonian, 80 minutes on hypered Kodak Tech Pan 2415 film. See the 8" ccd version.
