Not enough time

I started observing with my 12" Dobsonian at 3:35am this morning.
It was warm and windy, 20C with a NW wind to keep the dew away. The observatory walls helped protect me from the wind.
I mainly used an 8mm Hyperion eyepiece (190X, 25' field) but used a 13mm Hyperion (115X, 40' field) and UHC filter (*) for some nebulae.
These are the objects seen in order. They were found with a 50mm finder without a star atlas.
M83, N5139, N4945 - N4976, N5128, N5189, I4406 - N5643, N6101, N5286 - N5307, N5824, N5927 - N5946, N5882, N6067 - Mz2, N6165, N6153, N6300, N6231, N6302, N6357, N6337, M5 (an excellent GC), M12 - M10, M4 - M80, M107, N6369, M19 - M62, M57 - M56, M71 - M27, N6357* (again) - N6334*, N6188*-93, N6164*-65* (only 6165 seen with 8mm EP, 6164 seen with UHC), I4628*, M20* - M8* - N6559*, M16* - N6604 neb*, M17*, N6590-95, N6723 - N6726-27-29, M11, M22 - N6638 - M28, N6960*-92*-95*, N7000*, Io-Jupiter-E-G-C, Neptune, Mars, Uranus, Venus - a brilliant arc.
I had trouble with cloud blowing in from the west at the end and twilight (started 4:50am) so I quit at 5:05 am.
I should have started earlier, 1.5 hours was not enough time. The list above contains 4 open clusters, 20 globular clusters, 20 nebulae, 11 planetary nebulae, 6 galaxies and 5 planets.
