The small a stands for astromodified: This camera is usually equipped with a filter that attenuates the red spectral range so that the sensor comes close to the human perception of color during daytime vision. For use in astronomy, this is a problem because the important H-alpha line, in which astronomical gas nebulae glow, also lies in range. This filter will be removed for the astromodification.
The astromodified version of the DSLR therefore has a higher red sensitivity in the range of H-alpha or SII than the original version. This makes gas nebulae in the sky accessible for photography. Since these regions are often particularly extensive, the astromodified DSLRs can fully exploit their large sensor.
The many advantages of astromodified DSLR for astrophotography:
- Ideal for extended nebulae, thanks to large chip and high sensitivity in the H-alpha range.
- Built-in computer: You don't need a laptop or an external power supply - no cable clutter!
- Lots of accessories and versatile applications.
- Monitor with LiveView
The conversion (astromodification) is carried out by PrimaLuceLab in Italy by replacing the original Canon filter with the BCF filter from Baader Planetarium, which was specially developed for this purpose in Germany. You can see the difference in the "Transmission curve" illustration.
The Canon EOS 750D:
- The rotating and tilting 7.7 cm LCD touchscreen prevents unhealthy contortions at the telescope. No matter how the focuser is positioned, you can rotate the camera display with the preview and all important control panels to a comfortable position.
- APS-C sensor with 24.2 megapixels: Small pixel size for high resolutions!
- Powerful DIGIC 6 image processor
- ISO range of 100-12,800 (expandable to ISO 25,600)
- Images can be transferred wirelessly via Wi-Fi with NFC. The Camera Connect app allows remote control of the camera via smartphone or tablet. Such wireless connections are ideal for astrophotography.
The scope of delivery of the astromodified camera is the same as that of the camera manufacturer: camera body, battery, charger, USB cable, manual.
Please note: For astromodification, the original packaging of the cameras is opened and photos are taken for testing purposes so that the counter is no longer zero. However, the cameras are of course not used. Used goods are expressly marked as such in our shop.
