[Help] Tripod Heads for Astrophotography

[JDStellar]

So I have been on the market for a tracking system for astrophotography for some time, and I have finally taken the plunge and purchased a Skywatcher Star Adventurer to start. Sadly, that was all I can afford so far and so am in need of an equatorial wedge (which I think I will try to create myself for the time being) and, a tripod head.

When it comes to the tripod head, I'm not sure exactly what to go for, I know a geared head would be optimal, but I just can't afford it at the moment.
It will need to be able to carry a EOS 6D and 70-200mm with ease (I think)
Any suggestions would be greatly appreciated.

Thanks
