After tuning my worm gears last Thursday to minimise some obvious backlash on the EQ6-R mount I managed to get the mount guiding ok at around 1.00am after battling with passing cloud earlier in the evening
Picked a test target in the south east, NGC 3324 Gabriela Mistral Nebula as I hadn’t imaged it for nearly a year.
Still have some work to do on the mount, mainly balancing
