John, I just got my Mk IXA and everything seems to work to some extent, although the bubble cannot be made to disappear, I will probably have to fill the chamber some, but at the moment the bubble seems to be just about the right size, so I should be able to make a sun shot or so (if the clouds would only disappear). I have one problem for night shots, though: I cannot seem to find what type of battery should go in. I have checked Steve Grobler's site (www.users.bigpond.com/bgrobler/sextant/sextant.html) and all the links this provides with some very useful data coming up, but no specs for the battery. Can anyone help me out here? I don;t have the 12/24 V attachment, so I will have to work with the batteries in the battery compartment. And John, would you say that the manual you mention adds enough information to what is available via Steve Grobler's site to warrant the (rather expensive) purchase of that manual? And does anyone have a comparison with the other Mk IX manual available on eBay (auctions like 150133632158 which has finished)? thanks Ronald On Aug 7, 1:55 pm, John Gilbertwrote: > Those amongst us who enjoy owning and using these sextants may be > interested to hear of a newly written manual in Adobe Acrobat format > covering detailed repair and reconditioning of this model.
