Hello Sam,
I bought the Asi071 directly from ZWO - is it nevertheless in any case possible, to send back the camera about a local dealer (in my case "Teleskop Service") even if I did not buy the camera through the dealer?
Furthermore: Also Teleskop Service does not know - regarding to their homepage - something about an upgrade service; but up to now, I have not asked them directly...
Best regards
Joachim
