Tech@ZWO
I actually just asked a similar question after creating an account and did not realize the question had most likely been asked before. I read elsewhere in this forum where a response from a Tech was that ZWO is determining how to implement a lower gain for HCG to activate. I would imagine a user specified gain setting to activate HCG can be implemented somehow. After all, there is another 585 model camera out there that is making additional sales simply because of this very feature it provides. I would like to see ZWO implement it too. That way potential customers have a choice for this feature versus only having one, which is a non-ZWO model.
