Do you reckon this would be a valuable addition for deep sky photography if you were imaging the sombrero galaxy and wanted it larger in the field of view????

Sorry Mark - typo. "DSLR".
Yes, you can take a (newer) 5x PowerMate apart, exposing a thread. You need an additional adapter which threads on to this and that adapter, in return, then supplies a standard T-thread for your camera's T-ring. Here's a photo...
It's not the sort of thing you use to "magnify" deep sky objects - and neither is a 4x. Barlows decrease the incoming light, so you lose an f-stop or two, making exposure times all that much longer. They are great for planetary via webcam, and lunar work either via a webcam or DSLR. Here's one of the moon I took with my 820mm focal length refractor, the 5x PowerMate and my DSLR.
