Thought I'd pass this along...
Canon was in attendance at this years NorthEast Astronomy Forum (aka NEAF...
...) and was asking its booth attendees to fill out a questionnaire for what they would like to see in a new DSLR geared for astronomy. (For those who remember, Canon did offer the 20Da a few years back which offered such niceties as a broader-spectrum CMOS filter and an early version of Live-View focusing.)
Now, I should have just grabbed a copy of the darned thing to post here, but I'll do my best to recall some of what they were looking for...
A question about size preference...Rebel, 50D/7D, 5D2 or 1D.
A question about features...ISO...NR...MP...etc....and then there was this interesting choice...mirror, no mirror...which prompted me to get into a discussion with the two reps about what they meant with that question. This lead to a discussion about whether the camera would have a typical optical viewfinder or whether it would be a Live-View-only camera, and would the camera be a dedicated astrocam or could it be used for normal photography, as well. The one rep mentioned that Canon "already has a transparent mirror" which could find its way into such a camera (which I thought was interesting to hear) and so I enquired whether they were referring to something along the lines of a pellicle mirror...to which they said, yes, they were looking at that and something else that would work the same way. (Hmm, interesting again.)
And, finally (though there were a few other questions that elude me) there was an open question regarding whatever else one would like to see in such a camera. Which led to another discussion about high-ISO capabilities, NR and video frame rates since the reps saw my responses for ISOs of 200,000, 400,000 and 800,000...improved NR and DR...and full-HD rates of 120, and 240 fps. As I explained to their questions...well, now that we have ISO 102,000, can we clean that up to perform like ISO 1600 does today...and since you're asking for a wish-list, why not double that and more, there are lots of applications for this with live viewing of aurora, and many other telescopic faint-fuzzies!...that it was "clean" who would want for an expensive, cooled CCD cam and all the gear one needs to hook up with that just to get some images...and for high-speed shutters there are lots of events from occultations to hummingbirds in-flight for which one could use real full-HD slo-mo. I told them that when they make a camera that I can use for existing-light photography of owls at 2 a.m. in the morning, I'll buy it! We all chuckled.
Which brings me to the point of my post...
I am curious, since Canon is asking, just what is it that you would like to see in a camera specifically designed for astrophotography, and, in a broader sense (or, narrower, depending how you look at it!), extreme low-light conditions?!
