Quick question for any of the people keen on astrophotography and infrared photography out there. I know people sometimes get the sensor filter replaced to improve the transmission up to around 700nm for astrophotography to pick up the Halpha emission from nebulae. I also know you can essentially remove the filter entirely if you want an infrared only camera. Does anyone ever combine these and do IR astrophotography at 850nm?? (Specifically using a camera - I know the CCDs you can buy for telescopes can do this).
(In case anyone is wondering - reason for asking if I've been asked to give advice on the use of IR LEDs for lighting and it's impact specifically on astronomy - I know where I stand with on-telescope CCDs, but not so sure if anyone uses any of the very red IR filters with cameras for this, hence the question).
