Description

Messier 5 or M5 (also designated NGC 5904) is a globular cluster in the constellation Serpens.

M5 is, under extremely good conditions, just visible to the naked eye as a faint "star" 0.37 of a degree (22' (arcmin)) north-west of star 5 Serpentis. Binoculars and/or small telescopes resolve the object as non-stellar; larger telescopes will show some individual stars, some of which are as bright as apparent magnitude 10.6. M5 was discovered by German astronomer Gottfried Kirch in 1702 when he was observing a comet. Charles Messier noted it in 1764 and – a studier of comets – cast it as one of his nebulae. William Herschel was the first to resolve individual stars in the cluster in 1791, counting roughly 200.

I had 80 subs, 35 x 120 and 25 x 180. Seeing wasn't good and at some point the neighbors motion activated lights came on ruining several subs. Auto focus was having trouble I think due to seeing. Lost more subs to bad focus, fell asleep at the PC and the run was over when I woke!

So I went from 3+ hours to under 1 hour of total integration.
