This Mark IX has been modified by its current owner in order to be operationnal again. But he says that he had to cut off the averager that was beyond repair. I know this guy who is very knowledgeable in Hughes MkIX. I trust this sextant can be used for backyard or desert navigation once the index error is identified. If you live between 40-50 degrees north latitudes, for a NE-NW orientation you'll have plenty of high altitude star shots available in summer, and very few in winter. Sun rise shots are possible now and in summer. JPP

One of these is on eBay right now. It's said to be in fine working order; apparently overhauled by seller in England. I'd like to know it's suitability for practice from my deck which faces north and where the peripheral lines of sight due to shoulders of flanking hills only give me NW to NE. So it's mostly going to be star sights at night.
I once had a Navy Mk. V and liked it a lot, especially the clockwork averager. I can't tell if the Hughes has an averager, though there does seem to be part of a key (cut off) at the edge of one photo.
Thanks, Hewitt
