31/08/18 Aquila binaries part 2.

Swadlincote C6r and 8″ Newt.

Aquila. Rich in binaries is a happy hunting ground for multiple stars. I set up both the 200f6 Orion Optics Newtonian and the 150 Celestron refractor. The skies were not the best with poor seeing allowing to get to 1.4″ and an unsteady 1.2″ in 36 Andromedae.

However it was a great test for the old school design Vixen LVW eyepieces. The 42mm (2″)is still available from First Light Optics. It’s smaller than you think. The field stop is amazing , right up to the edge of the bottom thread . The LVWs are Lanthanum glass and the design is 8 elements in groups. They have 65 degree fov. and a generous 20mm eye relief. The 42mm weighs 545g, 22mm (1.25″)346g, 5mm (1.25″)465g. The 22mm is considered the gem of the set and gave that crisp wow in both scopes.

Target on such a poor evening was Aquila and return to multiple and binary stars. In a wide low power mode,the multiples Σ2547 (SAO 162847), Σ 2545(SAO 162843)and LV 21 (SAO 162829) were caught together.Quite surprised to be catching the fainter companions.
57 Aquilae is beautifully bright.
π Aquilae (SAO 105282) is a lovely orang gems ,classic showpiece, prise the A apart for a tight 1.4″ split.
Huge moon soon appeared with a misty glow in the east , time to pack up ,
Clear skies ! Nick.
