Tested last night IRL
Same problem with dome locking stuff, quickly solved
i've tested multistar SEP guiding, and did'nt noticed any improvement on my guiding accuracy but it needs more testing obviously
i tried Backlash measurment for DEC axis, but i could'nt achieve any calibration, i have to understand what happens (possibly mount problems)
BTW calibration plot is really usefull !
i also tried Bahtinov focus assistant, but also need more testing : need to understand what graph shows
(it's also hard to use with manual focus)
