Currently stationed overseas in the middle east and I can't find any extension tubes for my ED102 to do some planetary. The part I am looking to have made is ESHEXEXT2

https://www.highpoin...cuser-eshexext2


The thread is M68x0.75 Looking to have either 3 made, or 1 large one that is the size of 3. the backfocus required to use a barlow is insane. Inside doesnt have to be threaded, just needs to have the external threads on one side, and internal on the other. A single customs form will need to be filled out to ship to an APO address. flat black paint paint inside and out is just fine with me. No fancy anodizing needed. any form of aluminum, not picky at all. Not even picky about the ID, or the OD, I am using a QHY183M and it has a small sensor. Ball park is good enough for everything but the threads. Has to be able to screw in and out of the scope. Not even that picky about the length.

I hear these are on backorder for a few months.
