Had another go with the Qhy cam last night, read up a bit on getting the gain and offset done correctly and didn't seem to get the artifacts I had on first light. With guilt put aside went after the convenient targets the Horsehead and Eta again. With the full moon and shooting back south over the Perth CBD think the end result wasn't to bad I think......30x180s lights.....cheers for looking.
