Canon Ra shutter activation using telescope

pselaphid — Tue, 24 Dec 2019 15:22:52 GMT

Took delivery of a Canon Ra plus the EF-S lens adapter for astrophotography use yesterday. Currently exploring features and testing. When using my EF-S lenses, camera works as expected. When attached to telescope via the standard EF-S ring, shutter is not activating. I feel like I am missing something obvious but can't figure it out. I set focus to manual and tried a few other setting changes. Still no pictures. What am I missing?

Check the menus to see if there is setting that disables the camera from firing the shutter when there is no lens attached. It may be in the Custom Funtions 5 menu, which is where it is on the EOS R.

Found it, camera settings icon number 5 "release shutter without lens".

Thanks!
