Where is the best place to purchase M65 Spacers
Hi, I am looking at getting a few different size M65 spacers for my Skywatcher esprit 150
My focuser racks out about 60mm or so to get focus, while it seams fine extended at this long distance, I was looking at getting say a 50mm spacer and put in front of my field flattener so that my focuser only has to come out around 10 -15mm to reach focus.
The theory for me is this has to help the reduce any flexures that may appear with a focuser being racked out so far.
So far the only place i can find them is AliExpress, I have not had any purchases from them before as i was under the impression that it was just very cheap stuff.
Has anyone had any spacers from them before and what is the product like? being spacers, i don't want them to be average so that when you screw them on they are just slightly out of square.
Or is there someone else out there that has these M65 spacers?
