As far as I know,  there is no ST4 port on any of the HAZ mounts.  I have read posts of people trying unsuccessfully to pulse guide HAZ mounts using PHD2.  I'm wondering if anyone has tried the Direct Guide option in PHD2 with a HAZ mount, or found any other method that might allow guiding with them.  I've read posts of people with HAZ mounts asking iOptron tech support about guiding HAZ mounts and were told that basically it won't work.  But maybe there has been a firmware upgrade or something I don't know about in the meanwhile…
