<DIV>Hello Bill,</DIV>
<DIV> </DIV>
<DIV>recently by chance I was animated by Guide to have a telescopic look on
P/Tempel-Swift-LINEAR (11P). Guide told me it would be a worthwhile object with
12.1 mag. But I found no hint of a moving object in the captured CCD frames.
Next night I had a closer (longer exposure time) look at the predicted position,
but again no indication of the comet.</DIV>
<DIV>Searching the internet led me to the site
_https://theskylive.com/how-bright-is-11p_ where I could see that I had no
chance at all to capture such a faint object. </DIV>
<DIV>How can it be, that Guide claims a brightness so far beside reality (~8
magnitudes)?</DIV>
<DIV>BTW: On the occasion of the flyby of (99942) Apophis on March 5-6, 2021, I
noticed that Guide claims Apophis not to be an asteroid. </DIV>
<DIV> </DIV>
<DIV>Yes, I had clicked to download updated comet/asteroid data and add it to
Guide. </DIV>
<DIV>Have I missed somthing essential?</DIV>
<DIV> </DIV>
