brings back memories JP... through the late 80's I did a lot of this using T-Max 400 ISO BW film which I processed myself and hypersensitised colour films (kept in the fridge) which incredible ISO then of 1600+... Scope was a hand made 8in F5...the work involved in twisted posiitons doing hand guide adjustments using a crosshair eyepiece...contorted for hours and you could go for 2 hours and then accidentally bump the scope and gone... havent kept a single image... could now do better on my mobile phone ...:-)
