As we approach the 50th Anniversary of the Apollo 11 moon landing, last night I thought I’d attach the Canon EOS R to my telescope as the Moon beckoned through wispy clouds.
Here is what the EOS R saw (with overlay) with a full resolution 1200x900 pixel crop showing the region of the Apollo 11 landing site.
The telescope is a Takahashi Mewlon 210 (210mm dia mirror, at F11.5) although I reduced the focal length to 1932mm by fitting a x0.8 Focal Reducer/Flattener in the optical train, to tame some of the off axis coma inherent in the design of the ‘scope.
I have also attached a couple of gratuitous crops where the image is more sharply defined towards the centre of the FOV.
Cheers
Dennis
