I'll use both UCAC 3 and UCAC4 in guide

Last night, while using the ccd camera and scanning thw geo sat belt, I noticed a brighter star, that didn't show up in guide. I was using the ucac 4 catalog. After I switched to ucac 3, the star appeared.

 

Interesting, to pick a area of sky, and use ucac 3. Then when I switch to UCAC 4,watch stars that were there, appear fainter
