Quick Overview

6Da, based on the Canon EOS 6D model, is the astrophotography modified DSLR camera that offers higher sensitivity than the stock DSLRs cameras thanks to special astronomy filters we install in front of the sensor replacing the original one! Canon 6Da astrophotography modified DSLR camera comes with FullFrame color sensor 36 x 24mm, astronomy modified Baader BCF front filter, 3" display.


6Da, compared to cheaper DSLR modified models with APS-C sensors, offers a larger FullFrame sensor with 43.5mm diagonal: this way your telescope will be able to frame more of the Universe and will allow you to record also the larger objects in the sky, always with low noise and high sensitivity.

Canon 6Da astrophotography modified DSLR camera with Baader BCF filter

DSLRs are very often used for astrophotography because they offer large sensor and low electronic noise, all at a great price. But 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 6Da camera replaces the original filter with Baader BCF specifically designed for astrophotography, increasing the camera sensitivity and allowing you to take brighter pictures.

 

 

 

Technical comment by Filippo: "Cooled CCD cameras with FullFrame sensors are very expensive: with the modified 6Da astrophotography DSLR camera you will have, with less than half the price, a huge 43.5mm diagonal sensor. Thanks to the special Baader BCF filter that we install in the camera instead of the original one, you will have a high sensitivity even in the very important H-alpha line and a low electronic noise thanks to Canon's electronics quality."

 

APS-C sensor with big dimensions

The main advantage of DSLR cameras with respect to the dedicated CCD cameras for astronomy is to have a large sensor, bigger to the one of CCD cameras of comparable price. Below, you can find a comparison of the sensor size of our 6Da camera Full Frame sensor (in red) with the Sony and Kodak sensors installed on many CCD cameras for astronomy, such as Atik (in blue). As a reference we also report the size of an APS-C sensor. Notice how the sensor of our 6Da camera is much larger than the most of astronomy CCD cameras!

Modified filter for more 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 6Da camera replaces the original filter with Baader BCF filter specifically designed for astrophotography increasing the camera sensitivity and allowing you to take brighter pictures.

The chart above compares the transmittance of the Baader BCF filter installed on 6Da (red curve) with the original one of the Canon EOS 6D (blue curve). For reference we reported in green also the position of the H-alpha line. You can see how from about 550nm original filter decreases transmissivity while our modified filter lets all the light pass up to 700nm, so you can record more easily all the red weak details. The difference is huge considering the H-alpha line where the original filter has a transmissivity of about 30% while the modified one has a transmissivity of about 98%. Our 6Da, compared to the original Canon EOS 6D, it's more sensitive.

Canon 6Da astrophotography modified DSLR camera with Baader BCF filter

In our laboratory we perform the 6D camera modification and we install the astronomical filter (which replaces the standard one). We use special instruments and a clean room to prevent static electricity from damaging the internal components and the dust from depositing on the sensor during modification process.
