Well as is often the case you end up with something different. Well different brand.
Have put an order in for a qhy22 woohoo! Will be nice to have a cooled cam for a change. Hot summer nights will be dslr noise free from now on

Will have to stick to narrowband for a while though but that's ok. It's more expensive than the atik but has much better cooling etc.
Open to suggestions for first light it'll hopefully be here in a couple of weeks (full moon).
