I also have a 2008 model of the OK3 focuser. I use a Bakhtinov Mask for
focusing, but would very much like to use FocusMax.

If you've succeeded in making your OK3 work with FocusMax, we'd like to hear
from you.

I have a ASA 16inch with the OK3 heavy duty focuser. I have been using it with
FocusMax and ACP successfully for 3 years. I am using a Apogee 29050 camera
right now. I use to have a Apogee U16M camera before.

So again yes I have successfully -and at present- used Focusmax with OK3 focuser
and heavy duty focuser. However over the past 3 years I have had to reinstall it
because of new computer, software failure,ect. Each time I have had to reinstall
OK3 focuser drivers it has been a real headache on the OK3 software side not
FocusMax. Thus I always clone all of the hard drive using Acronis to avoid
having to reinstall any of the OK3 drivers. It always takes at least 1 to 2
hours of failures and then out of the blue success to reinstall OK2 drivers
cold. FocusMax is easy. Sometimes it seems like Black magic. If you would like
to talk with me I can be reached at my veterinary practice phone # 972-578-2553,
Skype as - astroveterinarian, or email res0hver@.... It can be done with
great success and it is well worth it. But it requires work and dare I say

I do not know whether it helps, but the pdf instruction in the following link


solved may issues for me (i.e. COM port not found, connection problems to FocusMax etc.)...
ASA12N-OK3 or TEC140
FLI 8300 & FLI FW2-7 or XPress H694 & XPress USB FW
