- WO 50 Guide Scopes
- Must Have for Guide Scope
Very helpful item
This focuser is the perfect length to make an ASI290MM minicam parfocal with an ASI178MC camera. So the guidescopes can be adjusted to focus the ASI178 then the ASI290 can be inserted and the focus adjusted with this focuser without disturbing the scope focus for the ASI178.
This should be part of the OAG...
I would have just paid more for the OAG in the first place if it had this attached. Guiding was always a huge pain because I struggled with getting things in focus. This simplifies it so much. Highly recommend.
High quality part for a good price.
Works great, on a not so sturdy OAG
Good. Working with my AT 102 EDL, ZWO OAG and QHY QHY5L-IIM. As good or better guiding than my old 60mmguide scope now with the OAG, just easier to focus now.
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.
