Loving the EOS Ra. Does great daytime images in addition to being a colour deep sky imager, but I wanted to try it's 4k video capability. It crops the sensor so in 4k it's virtually pixel for pixel. Used a 2x barlow on the 10 inch f5.6 scope. Stacked it then used Wavelets. Here is the result. Full res here.
