Thanks Peter and Tim,

My guiding is typically running between .75" and 1.5" depending on how low in the sky I'm shooting. It has gone as low as .5" but that's the exception. I've made some adjustments to the gear mesh but I'll have another look to see if that helps. I'll let you know.

That said, I think it would be a great feature for the EKOS guide module to include the ability to separately determine exposure length and guide pulse frequency.
