Looking for my first Sky Tracker

Hi All, I am an experienced photographer and have also been using telescopes with dslr mounts to take stills. I’ve wanted to buy my first star tracker to begin taking longer exposures.

Any advice for an amateur? Money is not really a deciding factor. I would rather spend money on one that is high quality instead of buying a cheap one to start then a more professional one later on, I’ll learn quickly.

I’ll be shooting with an 1XD and 70-300.

Any help is greatly appreciated.

Thanks in advance!
