Imaging with PHD2 guiding (Re: New file uploaded to ap-gto)
Some awesome results again, Roland! It looks like you have found the magic combination of settings for the Mach2 / PHD2 combo. Once I get decent skies here again in San Jose I'll also be trying those

Unfortunately running different PHD2 algorithms on a mount that isn't showing any problems doesn't really tell us anything - I would expect that all the PHD2 algorithms will work on a well behaving se

Hi Roland, The default guide algorithms in PHD2 do indeed attempt to correct for hysteresis and keep a history of previous guide corrections and apply that history to the current correction. Given the

Just to go back to Roland's original post on this: "Turning on the guiding produced huge oscillations in both RA and Dec that could only be tamed by setting the aggressiveness to a very low value" So
