First, my advice is to post on the refractor forum because you are far more likely to get a response from someone that uses this configuration. This forum is not the most visited forum on CN by a longshot.
If you don't get an answer here, you can probably estimate it by using the data in the Maxbright Owners Manual.
Just measure your back focus and use the table in the owner's manual to see if you can reach focus.
The WO is about 96mm vs about 110 for the Maxbright, so subtract that figure as well.
Table is on page 4.
