    Vanguard 3 / #00020 / #59007A was watched in telescope starting just before
    Altair. It was predicted at 10 mag and 1/10 degree under Altair so started
    search on the approach side with Altair out of field of view. Dim, estimate
    10 mag. At 3.15.19 UTC in fov while tracking Vanguard 3 another sat was
    seen. Id as Delta 1 Deb / #12529 / #76077DH using IdSat.
    Also saw a small flock of dim 1st time for me Cosmos in telescope.
    
    TiPS is my favorite telescopic sat, you get 2 for 1 plus the flicker of
    light from the tether which can be long or short depending on the its
    elevation.
    Would someone calculate for my location what is the separation of the 2
    sats, or the lenght of the tether, for TiPS at the various elevations above
    the horizon? How much will it vary because of eccentricity?
