There are a few very portable DSLR mounts.

The 3 I am aware of are:

The Vixen Polarie About US$400 + Shipping has a weight limit of what it can take.
The Losmandy Star Lapse system US$695 + Shipping more professional looking and robust.
The Sywatcher multi tracker $559 its Alt Az, comes with 2 hand controllers and a tripod.

Of these the Skywatcher one comes with a tripod and 2 hand controllers. Its a bit unclear in the marketing if it does panning for time lapses. It implies it will but its unclear. Alt Az mounts typically are not great for tracking but the use of this for me would be up to 5 minute exposures with a DSLR using widefield DSLR lenses like 14-24mm range.
Also to do panning effects whilst doing a time lapse.

Has anyone used the above and can comment about best performance?

My main concern about the Skywatcher is that it will not track well enough for round stars 5 minutes at 50mm.
