more stars

I just downloaded the two Tycho add-ins for Cartes du Ciel (that's about 40MB of data) so I can go down to magnitude 12 stars. Sweet.

Re-examined γ (gamma) Aries. And there's the field star that I saw in the field...

Magnitude Tycho BT: 9.76
Magnitude Tycho VT: 8.63
Visual Magnitude: 8.53

How about that.


I was a little worried I had the wrong star...


That the Tycho catalogues show mag 12 will better simulate what I can see in my 'scope, which is rated to mag 14.
