Just an image to show the Sky Crane carrying its payload 40 cm over the edge of the balcony rails. Still not all wired up in this picture - but later trial runs have proven that it works! It polar aligns using the buttons on the control box to within 1 minute arc, and it can carry more than this. Much more.
It is designed to carry the new upcoming Astro Physics 1600GTO at 52 kgs plus up to a 400mm RC reflector. Sadly the said reflector is way beyond my budget - and it wouldn't even fit through the doors I recently discovered no matter how I park... So I predict now that a much more modest Officina Stellare truss 10"RC reduced to f6 will live out there one day mated to something like a FLI16003ML or similar. That would make a three night project take only two - whilst providing a wider FOV compared to my current setup. I'll still be producing rather mediocre images due to the location and my below par processing skills - but I will do it quicker in the future... :-)
