PrimaLuceLab Nikon D5600a Camera - astronomy modified DSLR camera

The D5600a DSLR camera is based on Nikon D5600 towards which uses a modified internal filter that ensures greater sensitivity, especially in the red channel. In this way the camera is more sensitive especially to the red nebulae and it allows you to record astrophotographies with exceptional ease of use!

We perform the Nikon D5600 filter change in our laboratory where our technicians, using appropriate instruments, replace the filter in cleanroom (to prevent dust between sensor and filter) and electrically static place. We are Nikon official distributors so our modified cameras keep the original 4 YEARS OFFICIAL WARRANTY (Nital) !

DSLR cameras changed astrophotography because they allow you to record great pictures with large sensors: all at a price much lower and with greater ease of use than the cooled CCD cameras! However, in order to maintain a correct color balance in the daytime pictures, DSLR cameras use a filter, placed in front of the sensor, that is not completely transparent, especially at longer wavelengths corresponding to red. In astronomy application this is a problem because the most important emission line, the H-alpha (emitted by many nebulae for example) is right in the red part of the spectrum. That's why our D5600a camera, based on Nikon D5600, offers a modified filter for astronomy.

Nikon for astrophotography

Nikon DSLR cameras offer all the advanced features needed for astrophotography like:

- low electriconic noise
- high ISO sensitivity (from 100 to 25600)
- Live View for an easy focusing on the screen
-  control from PC 

Among Nikon models, we selected the D5600 for astrophotography because it offers a high quality sensor and an swiveling touchscreen LCD screen that is particularly useful when the camera is inserted into the telescope's focuser.

Also, in the sensor of the D5600 the low pass filter was removed in order to increase the image's resolution compared to cameras that use this filter.

Modified filter for higher sensitivity

In order to keep a proper color balance in daylight use, DSLRs use a filter placed in front of the sensor that is not completely transparent, especially at longer wavelengths corresponding to red. In astronomical application that is a problem because the most important emission line, the H-alpha (emitted by many nebulae for example) is right in the red part of the spectrum.

Our D5600a camera replaces the original filter with a model designed specifically for astrophotography increasing the camera sensitivity and allowing you to take brighter pictures.

The D5600a is just designed for astrophotography and uses a special UV/IR Cut filter with higher transmittance (especially in the red patrt of the spectrum) compared to the original filter.

Alternatively you can purchase the D5600 FullRange variant that has always the modified filter but compared to D5600a, it's also sensitive to infrared and ultraviolet.

You can compare the transmittance curves of the two solutions in the right graph. Since many telescopes (for example the ones use lenses such as refractors) have no good correction in the infrared and the ultraviolet part of the spectrum, the D5600a is the most practical solution for astrophotography (since it cuts off these wavelengths). If you own a telescope properly corrected in UV and IR (such as a mirror telescope without internal corrective lenses), you can also use the D5600 FullRange version that also allows the infrared or ultraviolet photography .
