First the positive. 90 pages of the new book completed, estimated total 250 pages.
Now the negative. All my (5) observatory computers are XP-based machines as there are still plenty of astronomy bits running on ancient software. As you know Microsoft no longer supports XP, this is apparently no problem for the 4 Intel machines – but a big problem for the Athlon which has now kindly locked me out. Thank you very much Microsoft – like I need these unnecessary problems on top of trying to maintain a parallel imaging array.
