Magnitude/visibility of Pioneer and Voyager ?

Dont laugh (too much ! )

Wandering round that interesting site I stumbled into the AINTNO list.
(Pronounced AintNo way you gonna see that )
but some of them have been seen visually, even the afterglow of a GRB !

#84 is Pioneer10 and #93 Voyager1
Which made me wonder what magnitude are these now,  and the other two  ?

I guess a mission impossible even to image them ??

Not impossible to image them.  All you have to do is build a massive rocket and send your own probes (with cameras) to chase after them.  Won't cost much more than a few billion quid.  That's not so bad for astrophotography, right?

There's A Guy Works Down The Chip Shop Swears He's Seen Them

[Ptarmigan]

Heheee, nice one,

but he couldnt possibly cos I know a secret - they are parked on the dark side of the moon ( that is why they are so weak ) and were put there when NASA secretly went to the moon ( whilst pretending that all the moon landings were filmed in a studio )

I cant decide if the AINTNO list was intended as a spoof or joke and were surprised that any have been achieved,

or, if they are just marginally outside what was thought possible ?

Hence my question if anyone has calculated the magnitudes.

I've tried to estimate the mag of Voyager 1 at it's present distance and make it about 35 assuming it's albedo is 1.0.

I might be totally wrong here though. It might be fainter.

I'd go with Sly Reaper's option
