Hi Folks,

Checking the position of comparison stars for photometry of the "pair of the
year", HD209458 and its occulting planet, I ran into a difficulty. One of
the comparison stars, HD209775, is obviously very near HD209458, and in
GUIDE's
displays, it is not possible to see them as two stars. The one star image
which is shown between the two positions is identified by right clicking on
the image as either HD209458 or HD209775, depending on what star you last
ordered GUIDE to go to.

I suppose the stars are close together indeed and did not register
separately when making up the GSC, but is there any way to see them and
compare their positions in a GUIDE map?

To plan a photometry session on HD209458, I would like to have a comparison
map. This may be the more important as HD209775 is quoted by Gregory Henry
as a variable.

Anyone who has an idea what to do to get a complete map?

: In Guide 8, I put the Landolt data (and most of the smaller catalogs

: in there, due to its size; and the LONEOS file gets updated regularly,
: so you should probably download that from time to time anyway.
