This is a landmark image for us because it was taken by remote control from the house!
We now have a 350 metre wireless bridge between the observatory and the house. Starting up is still rather manual: fuel for the generator, remove the dust caps, that sort of thing. After that, all is done in warmth and comfort.
(In the more distant future, we'll have generator backed solar power up there, and Wake on LAN, so we can start the beast from the house. That is being investigated).
M22, or the Crackerjack (presumably because of it's resemblance to the eponymous firework), RGB, 15 minutes per channel in 5 minute subs, squeezed in between dark and moonrise.
Original image here is 0.55 sec arc/pixel, approx 35 min arc across, north on the left.
