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 Orion’s 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.

SIGMA ORIONIS.... σ Orionis .... Superb
Multiple Star... AB Combined at* Mag* 3.7 too close to separate for anyone,*** and star C at mag 8.7* at Sep 11.6 "* away from AB...with 2 magnitude 6.6 stars* Called D and E at sep 12.7"* and 41.50" respectively from the AB pair.......RA 05h 38m 45s* DEC -02° 36m 00s
BEAUTIFUL at any mag I tried ..A JEWEL of the sky like Beta Monocerotis.
Primary AB combo, creamy white, D and E appeared blue and faint purple respectivley. Faint C a white colour on the other side of AB.

Using 20mm vixen NLV beautiful Orange Star much fainter blue companion..dont use too much power on this...as secondary could dissapear.
Attempted 52 but not much time ordinary seeing and will report back.
