The new Olympus E-M1 Mark II can fire off up to 60 fps with its 20mp sensor. The catch is, auto-focus is disabled at that speed. So many asked, what is the point to that speed without focus. Well, I thought it may work great for hi rez shots with a telescope and stacking images. Typically I have experimented with moon or planet images with web cams or dedicated planetary imagers, with good results, but nothing with the resolution of the Olympus. So, for the first time I tested the theory, good seeing last night. Slapped the camera onto my 90mm scope (630 FL) and focused fairly easily with live view and fired off 80 shots in about 1.5 seconds (basically until the buffer started slowing down.) Kept the best 60% in Registax, so about 50 images. Entire time, including scope set up and processing, maybe 25-30 minutes, magnitudes less time than previous endeavors of a similar target where I have to set up laptops, focus is much more difficult, setting up the imagers is more difficult, wiring it all together, etc. Can't wait to try it with my 777 FL scope and an 11-inch SCT, but those take a lot longer to set up, but will see how it works on planetary with the SCT.

Anyway, just sharing my findings to any interested. Not claiming to be an expert at this photography, but this was both the easiest to take and best moon image I have taken to date so maybe some good info for a beginner.

My first reaction was, "are you nuts? Using a moon image to discuss high frame rates? That's ridiculous!"

Then I read the rest of the post and it all made sense. I am not an astrophotographer so I can honestly say, "I learned something new today."

Thanks for this info. Great stuff and really impressive image.

Very neat and sharp image of the moon.

I am really trying to learn about how to do an image of the moon with stacking method, i did shoot a video for about 30 seconds, but i didn't know how to process the frames, and the moon was moving in every second of the frames, so i am not sure if it will work or not, the sensor of the camera is very very small so even with my 80mm [400mm] achro scope the moon filled the frame and in very few seconds i managed to keep the full circle in the frame before it is moving and cutting the moon slightly, i did use SharpCap for capturing and RegiStax but didn't success.
