Ah thanks for the reminder…I need to perform surgery on the 183 mono I was planning to try. I remember seeing a ZWO plot where the AR rolls off transmission below 400nm, so I’d imagine they use much the same glass. The 462 has strong response in IR so it’s not the usual UV/IR cut. I’ll also be using an SCT so that extra glass will no doubt work against me.
It’s really fascinating at the moment, as I don’t remember seeing images like yours in previous years, so maybe it’s a factor of UV-sensitive cameras becoming a bit more common. Good times
