A 0.7" (1992) double quite
easily split with 400x and even noticable with 280x. This on the night
of my first sub-1-arcsecond split of OS 313. I am amazed and pleased.
I was puzzled for some time about the PA. I estimated it at around 300, but had read it to be 267. I looked and looked again, but it was really there, it must be 300. A moment later, looking again at the data in Skymap I saw the solution : It is indeed 297, by the 1992 Hipparchos measurments. 267 was old Struve data, form long, long ago... This mistake was a very good
comfirmation for me that I really saw the double and was not imagining
or seeing a reflection or so.
