That's why I don't consider it a naked eye object.  If it's that hard to 
spot even after having been found in binoculars, it's not appropriate for 
a list of bright sats.

What was your naked eye mag limit at the time?

Problems arise when we try to narrow down the lists too much.  For 
instance, HST is mentioned.  But for most of us, HST is only a binocular 
object.  It's only naked eye at low latitudes.  It gets to be a bit of a 
hassle to make lists for various latitudes.  Beginners may not realize 
why something on the Top 10 list is not visible at all.

List can not include the classified sats mentioned.  First of all the 
elements are not always current.  Again, beginners would not realize that 
they're not seeing those sats because the predictions can be off by a few 
minutes. 
I do compile VISUAL, but the elements are posted courtesy of TS Kelso.  
The folks at SATELLITE TIMES magazine have now provided him with a web 
site to distribute the elements.
Kelso gets the elements from NASA so they never contain classified elements.

TS provides many different lists.  This takes a lot of his time and I 
wouldn't want to impose on him by asking for even more lists that 
essentially duplicate what is already available.  We can't just make a 
new list for every observer's individual desires.

However, I do have a suggestion for all those who  want a list of just 
certain objects.  Make up your master list.  Get any of the larger lists 
that contain your objects.   Use Kelso's Passupdate to quickly update 
your smaller list.  This way everyone can have a small personal list of 
favorite objects always up to date.
