I’ve been using a Canon 600D at prime focus in my newt for some time now which is providing some great images of all objects
What would be a suitable Canon upgrade to the 600D in an APC-C crop sensor
I’ve read about the Canon 7D mk 11 having low noise and good Ha response ( Roger Clark ) but it’s quite heavy at 950 grams compared to the 600D at 590 grams

Any advice welcome

Cheers
