For our searches, we use several setups.
In the South-West of France, we use a 250/1000mm telescope on top of an SW EQ8. It lives in a non-motorised nano-observatory in the countryside (SQM 20.76, Bortle 4).
At night, the telescope is filmed and timelapses are produced.
In Western Canada, we use a 600mm f/4.0 telescope housed in an observatory.
Occasionally we use a 203mm SCT.
We also use the Slooh telescopes but their limitations restrict us to bright supernovas.
