Nikon D810a Review

With the release of the Nikon D810a, Nikon has entered the market for astronomical imaging, despite the company’s relatively tardy start in this area.

At first glance, the only discernible distinction between the Nikon D810 and the Nikon D810a is the small, white letter ‘A’ located on the front of the shell of the D810A. The D810A is, in essence, a tweaked version of the immensely popular Nikon D810.

The Nikon D810a has several Astro-specific functions besides the standard D810; the most exciting and impressive is a modified infrared-cut filter.

However, beyond its 36-megapixel resolution, which is the highest in the Nikon range, the D810a also has several other Astro-specific functions.

Nikon D810a Remote cable.

The D810A was simple to set up, and we only needed to reference the user guide once—to locate the option for front electronic curtain shutter control, which can be found in one of the custom menus. Other than that, we didn’t require the manual at all. In this mode, the effects of the mechanical vibration are no longer present.

The camera’s focal-plane shutter comprises two curtains: the front curtain, which opens to begin each exposure, and the back curtain, which shuts to conclude the exposure. After the front curtain of a camera with an electronic front curtain shutter opens, the direction begins to be electronically controlled, and it continues until the rear curtain is returned.

Opening the mechanical shutter before the exposure begins may eliminate vibrations induced by the shutter, which in turn helps to reduce blur. Although a countdown timer would have been helpful for us when taking photos with lengthy exposures, this is a minor criticism of the product overall.

Barnard’s Loop in Orion and a peek of the Wizard Nebula in Cepheus were captured using a single exposure that was five minutes long, set at f/2.8 and ISO 1000, and tracked using an Astrotrac mount. This resulted in the presentation of accurate star colors.

To evaluate the deep sky, we paired the D810A with a Takahashi FSQ106. As a result, our stacked photograph of the Heart and Soul Nebulae in Cassiopeia (comprised of 20 exposures at ISO 1000, each five minutes long) displayed outstanding clarity and superb color, even though the first quarter Moon was high in the sky.

It has been well worth the wait for Nikon to make their entrance into the market for astrophotography. The Nikon D810A is an excellent camera with a high resolution, produces appealing shots, and excels in Astro capabilities.

It would be ideal if Nikon incorporated an articulated display screen and a timer countdown display for use during long exposures.

Nikon D810a Lighting

All single-lens reflex cameras feature a filter in front of the sensor, reducing the amount of red light reaching it. This allows the camera to reproduce colors accurately while shooting in natural light.

Unfortunately, the transmission of the hydrogen-alpha spectral line at 656.28 nm, responsible for the red color in many emission nebulae, is decreased. This hurts astroimaging.

Getting the DSLR changed by entirely removing this filter is a specific solution, but doing so has several significant drawbacks: first, autofocusing is rendered inoperable, and second, the color balance of daylight photographs is shifted toward the red end of the spectrum.

The solution that Nikon came up with for this issue was to change the filter in front of the sensor on the D810A such that there is an increase of nearly four times in the amount of transmission allowed for the hydrogen-alpha area of the spectrum.

Using the D810A to take photos in broad daylight will still produce images with a slight pink color cast; however, this issue is easily correctable in Lightroom or Photoshop using a user-defined preset.

Nikon D810a Live View

A preview image equal to the one acquired at 30 seconds is presented when the long-exposure mode is used with shutter speeds longer than 30 seconds; live view photos may be enlarged up to 23 times.

When framing photos and choosing a star to focus on, we discovered that this combination was beneficial.

Nikon D810a Aperture

When the electronic front curtain rather than the mechanical front curtain is enabled (a choice that may be made in the ‘Mup’ mode), exposure time is conducted electronically, which removes the potential for mechanical vibration caused by the automatic front curtain.

We discovered that this produced images with more excellent sharpness when utilizing lenses or telescopes with a longer focal length.

Nikon D810a Intervalometer

We found the intervalometer particularly helpful when putting up time-lapse and star trail sequences because it enables the capture of up to 9,999 individual frames in a single series.

There is also an option called Timelapse, which, if you do not own movie editing software, may automatically make a movie file for you.

Nikon D810a Manual Mode

In addition to the P/S/A/M settings, there is now a manual mode for long exposures called M*. In addition, there are options for the shutter speed of four, five, eight, ten, fifteen, twenty, thirty, sixty, one hundred and twenty, two hundred and forty, three hundred and ninety, and bulb and time.

With this function, there is no longer a requirement to use an external timer remote.

Nikon D810a Sensor

If you want the most outstanding results, pair your full-frame sensor with optics of the highest possible quality. For example, lenses and telescopes that can provide an image circle of at least 44 millimeters would be ideal.

When the RAW data are stored as uncompressed 14-bit photos, the 36.3-megapixel sensor creates files that are 74.5 MB in size.

Nikon D810A FX-format Digital SLR

Last update was on: April 13, 2024 10:17 am
$1,350.00 $3,796.95

The Nikon D810a is a specialist digital single-lens reflex camera that was intended exclusively for amateur astronomy photographers. It is loaded with a variety of functions and has been optimized in such a way that it is an effective instrument for taking breathtaking pictures of the night sky.

The D810a’s improved infrared (IR) filter is one of its most notable characteristics. This filter enables the camera to have increased sensitivity to the H-alpha red tones that are released by nebulae. The upshot of this alteration is the capture of astronomical photos that are more accurate in terms of color, as well as more colorful and detailed. Because of this alteration, the D810a is advised primarily for use in astrophotography and may not be as adaptable for use in general photography. It is vital to keep in mind that this modification is the reason for this recommendation.

Even at higher ISO settings, the D810a’s 36.3-megapixel full-frame sensor is capable of producing high-resolution photos with good dynamic range and low noise performance. This is all thanks to the camera’s low noise performance. This is especially helpful for astrophotography, which places a premium on capturing minute details while reducing background noise as much as possible.
