out of the ordinary
This focuser on my Newtonian is out of the ordinary and not for every one but has 0 slop , 0 slip , low 25mm profile , no intrusion into the tube lightpath ,no worries about extra in or out travel with 3" travel , handles heavy loads and adaptable to robo focus .
Drawbacks are $$$$$$$$$ and large foot print and more $$$$$$, but it's the best focuser I have used to date.
