Not sure if you understand what I mean about view in LCD on back of Camera, vrs the actual view thru same 12.5mm eye piece.
If i look thru it without any camera involved, planets etc appear much larger. But when i use same eye piece in my adapter using the camera for video, it's reduced in apparent size a huge amount.
I'm pretty sure it's because of the smaller frame size involved using video vrs a full rez. single still. But then, if I'm video taping it, it still should appear very large (same amount of magification as i would see the planet using the eye piece alone with no camera.
Hi there, for best planetary imaging using a Canon DSLR, you need to be recording a 5x zoom of the "Live View" feed from the LCD sensor, not in video mode. If you do it right, the Canon DSLR setup can give you "almost" the same results as a dedicated planetary camera (such as a ZWO ASI224MC) if conditions are good to excellent. I myself have been imaging the planets with a Canon DSLR and Celestron Evolution 6" SCT with good results. I use the prime focus method (rather than eyepiece projection), but others like BQ Octantis use eyepiece projection.
You need to follow the instructions on this website and get yourself a program like BackyardEOS to record the Live View images to your computer.
Then you need to learn how to use the standard stacking and sharpening software packages for bringing out the best in your video feeds.
There's a lot to learn, but the rewards can be great.
Hope this helps,
