I missed an early start on what a viewing buddy down here tells me was a bottler last night but I am adding a report on five from January in 2017.
These five In January 2017 using 10 F5, 13 mm Hyperion Eyepiece .
Zeta Ori (Alnitak);RA 05hrs. 40.7mins; Dec -01° 57; c) 2.6; d) 166 e) m 1.9; 3.7. This is a challenging double but worth the effort. I needed my highest power eyepiece x250 to separate, yielding a stunning Yellowish and White close pair that will need a 4 lens and good seeing to prise apart. I found an aperture reducing mask helped.
31 Ori; b) RA 05hrs 29.7 mins; c) 12.8; d) 87°; e) m 4.7; 9.7
This one barely rates a mention in the annals and lies neglected near Orions Belt(see map below). However, though seen for the first time this season, I found the contrasting brightness and colour on medium power x180 made this a classic already in my collection. Primary orange with a faint blue companion in a rich field.
Rho Ori; b) RA 05hrs 13.1 mins; c) 7.1; d) 64° ; e) m 4.6; 8.5
Rho(ρ) looks a little off the beaten track, but it is well worth the search. Again, a stunning contrast: primary, orange and its faint companion a light blue which seems well separated at medium power.
