Very informative presentation. We need more of these, they’re very helpful.

A nice presentation and a powerful tool to help us tune our systems. I'm a user of hocus focus as well as a tilt device. The process is tedious to say the least.

Hi guys thank you for the information, very helpful, I’m setting up a new focuser, specifically the PrimaLuceLab 3” esatto with 0.04 micron per step, what will be the easiest way to determine my step size? thank you.

Wish I had been available to join the stream last night because my question would have been around why aberration inspector fails, even though running hocus focus results in a very good fitting model. This is a constant thing, too. I'll run hocus focus and get back a curve with a model fit of 0.99. I run aberration inspector on exactly the same star field and even though the curve looks the same, aberration inspector throws up an error saying the model doesn't meet requirements. Why?

[@bezain7663]

Too bad you didn't mention the different fitting options ( Hyperbolic, Trends, Parabolic, etc ...) and explain how to choose the best one

[@georgehilios5079]

I didn't because you should always choose Hyperbolic, which is the default.
