Cue the Sky-Watcher Star Adventurer Mini, affectionately generally known as SAM, which may take a payload of 3kg but it’s comparatively simple to squeeze right into a camera bag.

For such images a tough alignment with Polaris is all you want, one thing that may be executed simply and rapidly utilizing an included inexperienced laser pointer. 

The Transfer Shoot Transfer is not going to precisely observe Polaris for greater than about two or three minutes (although the broader and lighter your lens the longer it’ll stay correct sufficient). However when you’ve got a fairly quick wide-angle lens none of that’s going to matter a lot. If in case you have a telephoto lens although, look elsewhere.
