Hello mate. If you are really accurately polar aligned and the scope/ camera etc is balanced and there is no wind, I still would say you will be limited to approx 30 sec max exposures. That will still give you lots of sky if you use free programmes like Deep Sky Stacker to stack your (preferably) RAW canon frames and stick to bright objects.
Eventually though the rotation of the images will nerf your nads, so most folks end up using a guide cam. Doesn't have to be expensive. And a lot of the guide software is free. Webcams can do it.
Of course you can polar align really well then manual guide. Then buddy, you can do anything with your rig!!
My first astro shots were on a fork mount (not an equatorial), of some planets and a comet. I was so inordinately pleased with them I have not looked back since.
Good luck matey!
Graham.
