double image on asiair plus stack

[gmendezc]

why this happens, some times when Im capturing images a fram came out of register with the others. My mount is a heq5 pro, my scope is a maxvision 102 apo triplet, my guiding famera is a zwo 585 MC, my guiding scope is a askar fma180 pro, and my main camera is a zwo183mc.

It doesnt happens always but some times a frame comes out of register.

Im using a asiair plus. my equipment is onlu 18 pounds of weight.

my latitude is 9.3 degrees

 

need help on this.

What was the per image exposure time?

I've found the live mode has a habit of not registering images well as last time I tried it my stars started to elongate and I was only doing 30s exposures at the time. Might be better to stack the individual subs afterward either within the air on via other software.

A gust of wind is the usual culprit or a cable snag
