An integrated white LED flashlight, with two output settings, gives you the illumination you need to get to your observation point and set, and a separate red LED light allows you to perform tasks like swapping eyepieces or attaching filters without affecting your night-adjusted vision. The PowerTank has a compact form factor at 7.5 x 3" and weighs just 2.25 pounds. Two straps are included so you can either hang it or attach it to the tripod, but if you want to leave it on the ground it has an IP65 rating, making it dustproof and water-resistant.
