- What's included
Compact, Pro-level Mirrorless digital camera professionally Astro-Converted for increased 4X H-alpha sensitivity and 6X Sulfur II sensitivity with a Big Full Frame sensor for about half the price of a Color Cooled Camera with the same sensor size. The stock UV/IR blocking sensor filter is replaced by the Optolong Luminance UV/IR blocking filter with Enhanced Spectrum (Visible + H-alpha + Sulfur II). User friendly for aspiring astrophotographers expecting an easy way to capture images of deep reddish nebulae structures.
Condition: Used excellent condition body with minor signs of cosmetic wear.
Straightforward Camera Control and Focus process
The exposures timing remote control is simply doable with a remote shutter release device or with Canon EOS Utility Free Software or Astrophotography data capture software like Backyard EOS or Astrophotography tool. 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 Vari-angle LCD touchscreen, 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 a mirrorless camera, its smaller body cause significantly less light obstruction in Hyperstar/RASA configurations compared to a DSLR, making it a better choice for Hyperstar C9.25/C11/C14 SCT and RASA 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 R is not compatible with Celestron RASA 8 Astrograph.
Best EAA Experience
Wifi-Capable feature will facilitate EAA (Electronically-Assisted Astronomy or Video-Astronomy) sessions with smartphones or tablets through the Free Canon Camera Connect App taking single frames shots. Broadcast to the entire 3rd Planet with your smartphone or tablet screen recordings/sharing through Zoom Cloud Meetings App or posting in social media platforms. With desktop or laptop computers, total intervalometer control is possible with the Wifi connection and Canon EOS Utility Free Software in Bulb mode for a completely wireless setup experience (No power/data cables).
Suitable for casual photography
This Astro-Converted camera can still be used for casual daylight photography setting the custom white balance with an 18% gray card shot or with Adobe Camera Raw white balance presets and an original white balance filter is not mandatory. For accurate color balance on portrait pictures or product pictures, the stock version or a OWB filter must be used.
**Out of focus NIR: With the Enhanced Spectrum modified camera, depending on the lens, telescope or optical corrector used, some imagers might experience a little bit bloated stars due to the near infrared light slightly out of focus when a refractive optical system does not have at least one ED (Extra-Low Dispersion glass) element. This chromatic aberration could be mitigated with post processing correction using computer software.
