Hi guys,

So looking at the attached image, this happened a lot last imaging session and there was no wind. I had to throw out about about 60-70% of the 2 minute subs due to this. The others were acceptable to use and had pretty round stars. So that in mind, what might be the most obvious reason for this?

Gear used was the Star Adventurer with dec bracket & counterweight, Redcat51, Fuji X-T2. No guidescope or autoguiding. I balanced the gear as best as possible for the image shot, and polar alignment was also good. Im guessing its either the lens & camera were too heavy for the Star Adventurer, or perhaps something odd with the SA gears themselves.

Anyone had these and found a fix?
