Description

One more progression in collimation. I am making one 1/64 screw turn adjustment every couple nights as it appears pretty much zeroed in now. Wei-Hao Wang noted will never be perfect due to flexion of 5.2 lb SBIG STT8300M hanging off the side of the scope.

This set up is somewhat forgiving due to the small 17mm K8300 chip and the circle of focus of the Tak is 44mm.

I need to check the saturation of the 100s L lights I am taking to make sure it is optimal. The center of M94 is pretty much almost saturated.

Comments for improvement appreciated.
