(Pier-6) How to perform darks on a ZWO 6200 with OAG LOL We have been struggling to get darks on this camera due to light leakage and the fact that ZWO cameras do not have a shutter, so in the end have resulted to extreme blackout techniques as we have found out online that the new ZWO M68 OAG is prone to light leak Black refuse sack to the rescue and they are now done. Sorry it has taken so long to get the new darks done but i hope this explains a little as to why...
