My 150mm F5 was upgraded to a Crayford 10:1 foccusser. NO FINDER SHOE AT ALL ON IT. Have also two 120mm scopes one a skywatcher F5. It has the finder shoe. And so does the unbranded F8.3. But not my 150mm. The F8.3 was a donation to my outreach. It was donated after I purchased the 150mm and 120mm F5, from ISS ads.
