Sooooo, who's ready to trade in their D810 for the new 810a? Looks to me like it's only better for that very small percentage of shooters that use a tripod with a motor drive for shooting the galaxies far, far away.

Special purpose camera:
"The infrared (IR) cut filter has been optimized to allow transmission of the hydrogen alpha spectral line, resulting in four times greater sensitivity of the 656nm wavelength. The resulting images capture the brilliant red hues of diffuse nebulae and constellations in striking detail and fidelity. While not recommended for general photography,"

Yeah, thats the problem I have with the D800. It just don't capture the hydrogen alpha spectral line like I would like.

Sure glad I didn't rush to trade my 800E for an 810. What would I do now?

sory kid, without that enhanced spectral sensitivity your bedroom shots will forever lack those rosy red cheeks.

Not yet my cup of tea. I will stay with my D-800. Unless someone will give me a D-4s.

While I do use my 800e for astro work I have to agree with the above poster. The factory cut filter cuts way too deeply into the red spectrum to truly perform to my expectations. While the 810a would fit this bill the $1000 extra seems greatly excessive. Life pixel will do this service for a third the added price of the (a) model. The only other difference is the firmware mods to alter bulb exposures. Since I use programs to control exposure lengths this added feature offers no great advantage. While itsays not for general photography I would imagine that a custom white balance or manual PP would deal with this issue.

Ultimately over 3k can buy a very nice TEC cooled CCD+filter wheel

yeah! me too, and I was so hopeing it would : :lol:

I have to say that I never had occasion to complain about any spectral lines at all with my Kodak Brownie. :D

Why doesn't Nikon offer a great camera with several filters? It is so ridiculous to have to purchase an entire camera for a single purpose. In the film days, some prime lenses came with various filters that we could have rotated into position.

While, back in the day, you could find all manner of film choices.  Covering, while not the full spectrum, you could pick a particular range based upon the film. Then again the issue of prefectly flattening the film posed all sorts of issues like vacuum lines. With dslrs, to gain a different end of the spectrum you must either cut part or all of the spectrum your hot mirror regects. Which brings your exposure time into minutes or even hours. Or there is the option of voiding your warranty and altering the filter that sits on top of the cmos chip.

Im curious about the camera, but with watching Nikon as of lately, i'm willing to bet it is just a straight off the line d810 with a different hot filter and altered firmware. Correct me if im wrong but a d810 is basically a d800 with that same idea but added a newer processor also. 


Personally, I was hoping for a pro body design with no battery, flash capacitor so no real PCB all this would reduce/help with the noise from current being so close to the chip, all the extra space could be utilized for an active cooling unit.


I would have liked to see nikon make use of a full spectrum hot mirror, and adopt a clip in filter system after the lens but before the flip mirror, similar to astrodons version for Canon.

My new D810 arrived Friday and will be going back next Friday because I would have waited till May or June to get the "a" if I had known about it.B&H would give me a $1400 trade in but they will refund up to 30 days so rather than take a over 50% loss I will send it back, too bad I was really having fun with it.
