99 frames
M33 (Triangulum galaxy)
99x30s ISO 25600
360mm f/5.6
Nikon D750
Took a zillion (actually just under a hundred) frames at the most sensitive (most noisy) ISO setting, equivalent to ISO 25600; using a 180mm f/2.8 lens through a 2x teleconverter.
(combined using DeepSkyStacker software, which crashed a few times, but finally prevailed.)
