Ah yes, hindsight, Jim
I was so excited that I just put it on and later thought...............Oh dear. (It was probably mentioned in your instructions for installing the hotspot.)
I cannot rotate the mirror due to the positioning of the velcro that locates the cable sling, and the location of temperature sensor. Perhaps in future when the mirror needs work.
I'll soon get the current orientation and the effect of collimation screws 1 and 3 memorised.
