Hi Would like someone to sense check my calculations before I proceed with my purchase. Currently have a OS RH200 veloce and QSI 683 and wanting to upgrade the focuser with a optec leo. Need you help in order some adapters . I have calculated that the back focus is 43mm short of what it needs to be . So was thinking of order 2 adapters with a length of 21.5mm each to make up the short fall. On the telescope side will be the first image and on the focuser side will be image 2 Am I correct with what adapters I shall order or have I mess it up. Thanks in advance. John

HI Thanks for the update , when a connect the camera to the updater it ask for the location for the new drivers and firmware do you have these as well please. Thanks John

Hi Can can anyone help please. Had my QSI 683 for over 5 years now and everything was fine util recently when this banding issue came up. Nothing has changed on my set up , so I changed the USB lead and power supply but same old banding issue appeared as what appears in this thread. Have spoken to QSI who tells me the firmware update it not available any more !!. Does someone have a copy of the firmware update or another fix that can help. Regards John
