Built-in Bluetooth and Wi-Fi aid remote control and image transfer. numerous customization options allow setup for your preferences.
Image Quality
Optimized IR transmission delivers excellent results when shooting nebulae and other deep space phenomena. The 30MP sensor provides high resolution with effective noise control up to mid-range ISOs. Dual Pixel CMOS AF delivers fast, accurate focusing in live view and video. The ISO range allows balancing noise and long exposures. Dynamic range performance enables grade recovery of shadows and highlights.
Functions
For astrophotography, the EOS Ra offers useful tools like focus peaking, focus bracketing, and exposure simulation. Versatile 4K and Full HD video modes allow capturing astro-timelapse sequences. The built-in intervalometer enables easily creating timelapses. GPS tagging aids organizing images. Powerful RAW processing in DPP software helps maximize image potential. Overall the Ra offers a great toolkit tailored for night sky photography.
Conclusion
The Canon EOS Ra delivers impressive dedicated astrophotography performance in a versatile mirrorless camera form factor. For wide field images and timelapses, the modified IR transmission provides excellent image quality without an astro mod. Refined handling, wireless remote control, and RAW processing power enable maximizing results. For photographers looking to affordable capture the cosmos, the Ra is a great astro-optimized choice.
