    Does the job and does it well.

    Purchased to simplify focusing the guide camera in my off axis guider. Much easier to and hold precise focus with the Helical Focuser. This one is well made, easy to use and holds its position well, and the price is what I would expect. Also, I have 2 ZWO cameras and the OAG and EAF are ZWO so the color scheme matches (ZWO Red)!!! OPT service and speed of delivery perfect, as always.

    Perfect for Lodestar X2 and OAG

    This focuser was the best method I have found to attach the Lodestar X2 guide camera to my OAG. It is fantastic!
