Nikon DSLR and Mirrorless Astrophotography Conversion Service

Free Domestic Shipping. Quality glass filters.

Supported cameras:

Full Frame: D750†, D600*, D610, D800, D800e, D810, Df*, D850, Z6†, Z6II†, Z7†

*These cameras will have dust reduction system disabled after the H-alpha conversion.

† The D700, D750, D3, D3S, D3X, D4, Z6, and Z7 contain an IR internal shutter monitor that may contaminate the shot when shooting long exposures. This will generally only affect UV shooting. The D7000, D7100, D600 and D800 also have this monitor but do not have this contamination issue. The light leak can be avoided in the Z6 and Z7 by using silent shutter mode.

FOCUS WARNING:

With Nikon H-alpha conversions, and particularly naked conversions, focus with DSLR lenses may not work. These cameras will only be compatible with telescope and manual focusing. For autofocus, please order the full spectrum conversion here. The following modes will autofocus properly after the H-alpha conversion: D3300, D3400, D810, Z6, Z7

WIDE ANGLE CORNER SHARPNESS WARNING:

We do not recommend combining wide angle lenses (wider than 35mm) with astro-modified sensors. Astrophotography thoroughly tests the optics of any camera system and lens. We have an in-depth article here on the issues with modified cameras and astrophotography. Corner sharpness performance is heavily tied to the lens being used, wide angle lenses compound this issue. We provide the highest quality glass possible, however, with certain body-lens combinations corner sharpness loss may occur.

Filters:

H-Alpha Filter :

Filter with expanded spectral response that covers the H-alpha and sulfur II emission lines. After conversion, the camera will have a greater than 4 fold increase in sensitivity in the H-alpha line compared to a stock camera, and a greater than 6 fold increase in sensitivity in the sulfur II line. This conversion will maintain the dust reduction feature in the camera and uses multicoated glass to reduce reflections and artifacts.  Above, an actual measured transmission curve of the filter. Internal transmission is close to 100%. Be careful when reading transmission curves,  some sources provide the more attractive internal transmission instead. All curves we provide are always measured transmission. Focus may not work on DSLR lenses.

Naked Filter:

The bare naked sensor. We take out all the filters in front of the sensor and leave your sensor unfiltered. There is no extra glass to cause any ghosting artifacts or attenuate any wavelengths, but your sensor will be much more sensitive to dust and scratches. Focus may not work on DSLR lenses.

Full Spectrum Filter:

Another popular option for astrophotography, allows you to use any filter over the lens to narrow down the recording band. Focus will be recalibrated for use with standard lenses. Can be ordered here

Focus Calibration Information:

Please note that on mirrorless cameras, we calibrate the camera to focus universally with all lenses. For DLSR camera’s our post-conversion focus calibration is set to 50mm, and will generally focus well with most lenses between 20mm – 300mm. If you are sending in a DSLR for conversion and plan on using lenses outside this range, or using one specific lens, you may want to include this lens with the camera so we can calibrate the camera to it specifically. If you have any concerns regarding lenses and your DLSR camera; please reach out to our customer service team before shipping the DSLR to us.
