Re: [APML] Film is not dead

Jerry,

Those are pretty amazing. I've certainly been thinking about a CCD 
camera for some time but the $12K price tag for what I'd want from SBIG 
is a bigger pill than I've been able to swallow. I was concerned about 
the OIII sensitivity in the DSLRs but it's quite good in the images you 
linked to.

I looked at his series of Veil nebula images and the one taken with the 
D70 has the most cyan color of any of them.

A modified D70 may be well be a viable alternative for those of us 
can't drop $10K whenever we want. ;-) In a couple of years they'll 
probably be a better model and no more expensive.

These are not astrophotos but I put together a comparison of a 
butterfly wing taken with film, a Nikon Coolpix 5700 and a Nikon D70 
(unmodified). I was comparing noise and resolution. Images are enlarged 
by 2 with no other processing.

The D70 is the best of the three and even the 5700 is better than the 
film image.
