In a word dont,
it uses an IR LED internally to monitor the shutter speed ect,
so will render IR photography a problem :cry:

That's a bloody nusance.  Were you thinking of modding your camera ?

That's an interesting thread.  It means the affected Nikon models are pretty much useless for modding for astro purposes.

I don't think i've ever seen an astro image done by a modded Nikon. Most people use the Canon's.

I think that's because you could never get a true RAW image from a Nikon - some kind of image processing was applied first.    I don't exactly which cameras are affected by this.  But it means that Nikons were generally avoided by the astro community.

Sore of true,
If you turned on the in camera dark frame option, and whilst it was taking the dark frame
turned the camera off the original file was saved unprocessed, but this was removed on the firmware updates.

looking through the threads its mailnly the newer ones,

D700, D3, D3s, D3x.

Correct, but there are a few people who do the IR mod for normal photography, who now cant.
Looks like they will have to goto Canon's~

On that subject there was an interesting thread on dpreview about the processing algorithm used for that part of the noise reduction.  Apparently that was changed for the D7000 so it's similar to Canon (i.e. no star removal) but it's all to no avail if they're flooding the sensor with IR.

I thought the reason people turned the camera off during dark frame subtraction was because that was the only way if bypassing the star removal and getting a raw raw?
