Re: [guide-user] Re: unusually bright asteroid/update

Gerhard Dangl May 5, 2012

Hi Bill,

before my posting I updated the mpcorb.dat file. And I had changed the
display settings several times.

It is really strange because after a setting change to show only the
first 100 numbered asteroids, Guide still shows this group of objects
with the wrong apparent brightness.

The only way I can switch them off is to change the mag limit below
their wrong reported bright magnitudes. Meaning a limit setting to +2mag
for asteroids does hide them.

Of course I have checked the guide.exe file too. It is the latest
version from April 19th, 2012. My PC system used is W7 64bit, German.

Regards
