Hi Jeff,

Thanks for the report. I've seen four pairs in Volans over the years. Went back 25 years to find my observations of these

Gamma Volantis (Dunlop 42) 25cm f/6 notes:

x138: Beautiful colour contrasting pair, A is deep yellow with B being cold white, well separated by about 15" in PA 300, two magnitudes of brightness contrast. A little like Alberio.

The spectra of the stars indicates K0 (III) and F2 (V). Just a bit curious in the difference between my colour(s) description and yours.


Zeta Volantis (Dunlop 57) My 25cm notes:

x181: No problem, attractive pair with a mid-yellow A and B is cold white + 5 magnitudes of brightness contrast, 4.0 9.0 Separated by 15-20" in PA 120. Thin field. The colour of B is subtle.



Epsilon Volantis (Rumker 7) My 25cm notes:

x181: Beautiful pair. A is off white/cream, B is cold white with a magnitude difference of 3 magnitudes, 4 & 7 perhaps. In PA 20 reasonably close, maybe 4". Very attractive.

Good to see you have a productive and successful session.



Best,

L.
