No - found a local metalworker (specialising in metal staircases and metal gates for properties) - the design was based off of a wooden concept designed by an engineer friend with astronomy experience. Because of the type of scope and mount, I wanted a low wall and not just a roll-off roof. I got inspiration from a local public observatory which has a big observation platform housing a 24" scope and a bunch of others where the entire roof and sidewall rolls back, but the final design is very different - I'm super happy with it, it's extremely sturdy yet can be opened with one hand.
Planetary and lunar imaging works very differently than deepsky imaging. The technique behind it is called 'lucky imaging'. Only about 20% of the sharpest recorded frames actually are used in the final image.
Individual recordings are 5000 frames at 133fps, the field of view of the ASI462mm camera is about 4x2 arc minutes, so a number of individual stacks were combined in a mosaic to reach this resolution and field of view.
Brussels is even named for being built on top off a swamp (a 'broek') covered in leather tarps ('zelen') = Broek-zele = Bruxelles = Brussels.
