I carry a small Joby tripod. It isn't even rated to hold the weight I put on it, but the super bend arms mean you can use them to help stabilize the camera.
Hard to explain, as I don't have a picture, but what I do is find a decent rock/stump/etc and attach the tripod to the camera. Then I bend the two front legs forward to support the lens and the rear foot as an out rigger the stabilize the left-right axis.
Only has a working height of an inch or two, but when hiking it is an acceptable compromise as it works fine for landscape and night sky pictures. Not so good for macro.
Using a small Joby (500g'ish limit) I have taken star pictures with an e-m1 mki and a 40-150/2.8. They weren't very good because that lens really needs a tracking mount, but they were sharp.
I've had lots of success with a smaller lens like the 15/1.7.
My point is, if your are reasonably creative you can work wonders with an under rated Joby and delayed release settings (diamond mode on Olympus cameras).
I realize I never circled backed to the topic...
I rely on IS most
of the time, and then get creative for long exposures.
