Overview
Compact, lightweight Mirrorless digital camera professionally Astro-Converted for increased 4X H-alpha sensitivity and 6X Sulfur II sensitivity with a generous APS-C sensor for half the price of a Color Cooled Camera with the same sensor size. The stock UV/IR blocking sensor filter is removed and the Low Pass Anti-Aliasing filter is preserved with Enhanced Spectrum bandpass (Visible + H-alpha + Sulfur II). User and budget friendly for aspiring astrophotographers expecting an easy way to capture images of deep reddish nebulae structures. The EOS R100 is currently the most unexpensive EOS R lens mount camera with APS-C sensor.
Features
- 24.1MP APS-C CMOS Sensor with 3.72 µm Square pixel size
- Up to 4X Hydrogen Alpha transmission increase at 656nm wavelength
- Up to 6X Sulfur II transmission increase at 671.7nm and 673nm wavelengths
- Stock UV/IR blocking filter removed and Low Pass Filter preserved with 425-675nm transmission range**
- ISO Range: 100 to 12800 (Extended ISO: 25600)
- Built-in 2.36m-Dot OLED Electronic Viewfinder (Nice Eyepiece Simulation!!!)
- 3.0" 1.04m-Dot LCD Screen
- Built-in WIFI (Great for Electronically-Assisted Astronomy with Phones and Tablets)
- DIGIC 8 Image Processor
- UHD 4K 24fps / HD 1080p 60fps / HD 720p 60fps Video Recording
- Improved Dual Pixel CMOS AF
- Compatible with N.I.N.A., BackyardEOS and Astrophotography Tool

Straightforward Camera Control and Focus process
The exposures timing remote control is simply doable with Canon EOS Utility Free Software or Astrophotography data capture software like N.I.N.A., Backyard EOS or Astrophotography tool run on a computer. Subject framing and perfect focus procedure can also be done easily with or without focus masks over Live View digital zoom using the camera’s LCD screen, and also with Canon EOS Utility Free Software or with the mentioned 3rd party software when the camera is connected to a computer.
Shorter body flange back focus
The RF Lens Mount features a large 54mm diameter and a short 20mm flange back focus distance to the sensor surface. Compared to a DSLR, the shorter flange back focus distance to sensor allows to fit accessories like filter sliders, Off-Axis Guiders or Camera Angle Adjusters within the typical 55mm imaging correctors’ back focus.
Great for imaging with Hyperstar/Celestron RASA Astrographs
Being an APS-C mirrorless camera, its small body cause significantly less light obstruction in Hyperstar/RASA configurations compared to a DSLR, making it suitable for Hyperstar C8/C9.25/C11/C14 SCT and RASA 8/11/36 imaging setups. Additionally, when imaging at f/3 or faster focal ratios, the focal point and sensor even illumination is critical, and compared to a DSLR there is no mirror chamber and no shadow projected from the mirror on the sensor surface. With such Ultra-Fast optics, exposures of 30 to 60 seconds single frames are enough and thermal noise is not an issue.
Celestron RASA 8 Owners: Due to the protruding hand grip on the camera body, the Canon EOS R50 might not be compatible with Celestron RASA 8 Astrograph.
