5 of 5 Cost Effective Autofocussing July 26, 2023
Reviewer: Ian Thompson from Leeds, West Yorkshire United Kingdom  
I had some issues with this at first, The unit wasn't reporting position or temperature and therefore wouldn't work with N.I.N.A or Sharpcap for autofocus, etc.
Here's where iOptron's customer service stepped up to the plate. They reached out to me with a firmware update that fixed all of the issues I encountered.
Now this electronic focusser works fantastically well. It's quick, repeatedly accurate and works perfectly with N.I.N.A's automated focussing. I no longer have to freeze outside while trying to get my focus dialled in. No more discovering half of my data is useless because of focus drift either!
The unit is beautifully minimalist, with just a USB port and two small buttons for manual control. Build quality is excellent and everything you need is in the box- even hex keys.
A great little autofocusser at an excellent price.
