    Default Nikon enters the Astrophotography Game - Nikon D810A Announced Today



    The official name is the NIKON D810A (not to be confused with the Canon 60Da), and it's the Talk Of The Town on all the Photography Review and Retailer websites.
    (And the subject of the "Nikon Rumors new..." Thread posted here last week...)

    Nikon USA:

    And surely many others...

    So they didn't mention cooling at all; I wonder if they did anything different given it is made for up to 15 minute exposures. The "astro noise reduction" to help with noise sounds good, but I would think they went through some effort to make sure the sensor did not overheat.

    Default Re: Nikon enters the Astrophotography Game - Nikon D810A Announced Today

    While I posted several reservations about a Rumored Nikon Astro Camera based on the Flagship D810:
    Full-Frame too wide a Sensor to be Illuminated well by most Scopes - especially those limited to a 2in Focuser Drawtube and/or an M42-threaded T-Adapter
    D810 is very Big and Very Heavy - 34oz

    I have to say that its impressive that Nikon went FURTHER in their Astro-adaptations than Canon did with the 60Da:
    In addition to the optimized IR cut filter, the D810A adds other features that are useful for astrophotography applications. A new Long Exposure Manual Mode is implemented, giving users the ability to set shutter speeds from 4, 5, 8, 10, 15, 20, 30, 60, 120, 180, 240, 300, 600 or 900 seconds (15 minutes), as well as Bulb and Time settings. Building upon the D810’s excellent low-light capabilities, the ISO range has been optimized from 200 to 12,800 (Hi-2 51,200), for maximum sensitivity with the optimal signal to noise ratio.
    The D810A also adds a new Virtual Exposure Preview Mode, which displays an estimated preview image and is available when shooting at shutter speeds longer than 30 seconds when in Live View. The brightened preview image represents a 30 second exposure, simplifying focusing and composition.
    The Longer Exposures available through the Manual Mode eliminates the need to switch between Manual and Bulb and using an Intervalometer or PC App (Canon 60Da made no accommodations beyond Bulb).
    The extension of "LiveView Exposure Simulation" from the usual 2sec max Exposure to a 30sec Exposure equivalent (and with a significantly more sensitive Sensor than the older 60Da) will go a long way to assisting AP Images with their Framing and Focusing tasks.

    But I still question the choice of a Heavy Full Frame Camera - seems like it limits the Potential Audience to only those with the most Expensive Scopes. (Maybe it will add fuel to justifications for Celestron, Orion, SkyWatcher to offer wider Focusers on more of their down-scale Scope Offerings...)

    Thermal Noise has been Reduced in many of the most current DSLR Sensors - Canon 6D, Nikon D750/D810, Sony A7s...

    Yes, it would be AMAZING to see a Mainstream DSLR Brand commit to Engineering at least the Potential for a Cold-Finger into their Astro DSLR Offering.
    Who knows, now that Nikon has Challenged Canon with this D810A, the Stakes may have been Raised to the point that Canon feels the need to offer a Cooling Solution...
    (Or it could remain just a Dream...)

    Interesting, A bit better than I imagined -- very nice new features --- but, given all of the tradeoffs, if I were given almost $4k to spend, I think a cooled camera probably still makes more sense. You save on noise (it will be interesting to get our hands on some actual long exposures taken with it), but give up sensor real estate. But that can be attacked with a longer FL scope.

    Coming from a Canon guy.....it looks impressive.....as does the price!! But I do like the Long Exposure Manual Mode. I agree with the weight, it would seem one would have to have a 3" focuser to handle that much weight, and for darn near $4000 one could get a pretty nice cooled CCD! But, hey, at least the DSLR manufacturers are looking, seriously, at AP'ers! I think it would pair nicely with something like a Tele Vue NP127is.

    I was really excited when I read this yesterday. That is until I realized the price! Way more than I am willing to spend. I'm suresomeone can afford it though.
