At my City suburban location I have a restricted view of the SE to SW due to my 2 storey roof line and huge council tree , therefore I can only capture a few hours or so on this target each night.
The weather over the past month has been cloudy but last week offered 2 relatively clear nights ( some passing cloud around 11.30pm to midnight)
I was lucky enough to capture around 4 hours on the Tarantula over 2 nights although I discarded about 15 subs due to cloud and a huge tree in which one smaller branch just blocks its path.
