sunday doubles

A Sunday night session with Big Blue, through clouds which were not in the forecast! Was able to see E & F in the Trapezium. The seeing was Pickering 6, not great (it was forecasted to be better).

Eta Orionis: Bright white, 1 delta mag, hazy but split (maybe scattered light).

Bvd 51: Picked out a wide, 2 delta mag pair right away using 8mm, but felt the slightly reddish A might be a very close pair. Used barlow though seeing did not support it. Did not split but suspected elongation. [The wide pair is it.]
05H 15M 23.69S -03° 21' 57.4" P.A. 317 SEP 44.5 MAG 7.76,9.56 SP F7V+G1V DIST. 83.26 PC (271.59 L.Y.)

BU 189: Took a while but was able to get a solid observation. Seeing needed to still (and cloud pass out of field of view) then a 3x fainter point comes to view with averted vision, can barely hold it. ~5”. [HDS 702 is the A star, 0.5” separation, not seen!]
05H 20M 26.41S -05° 22' 03.1" P.A. 285 SEP 4.6 MAG 6.41,9.80 SP B8III DIST. 281.69 PC (918.87 L.Y.)

STF 667: Pretty orange A and 2x fainter B, which is a little blue-orange. 5”
05H 14M 41.31S -07° 04' 18.1" P.A. 316 SEP 4.2 MAG 7.15,8.78 SP K2 DIST. 297.62 PC (970.84 L.Y.)

Bvd 52: Another one from this new designation! Passed RX Lepus on the way down, a medium deep orange. Bvd 52 seems a system of stars, all pretty wide. The closest two of similar magnitude, the other stars are fainter. How do they know / notice they are binary? [It’s a single pair, not sure which one.]
05H 18M 08.86S -16° 11' 13.4" P.A. 227 SEP 89.7 MAG 7.72,9.05 SP G/KIV+G3V DIST. 56.85 PC (185.44 L.Y.)

STF 661: Surprisingly large delta mag for a Struve, ~3-4 delta mag! But B star is brighter than a typical Burnham. 1.5-2”, B in A’s diffraction.
05H 13M 13.87S -12° 56' 26.4" P.A. 357 SEP 2.2 MAG 4.43,6.77 SP B9V DIST. 223.21 PC (728.11 L.Y.)

Iota Lepus: Bright but more widely separated B than STF 661. 3 delta mag, ~4”. RX Lep in finder, red-orange. [HUB 6 is a 0.4” 2.44 delta mag to A]
05H 12M 17.89S -11° 52' 08.9" P.A. 337 SEP 12 MAG 4.47,9.92 SP B8V DIST. 71.07 PC (231.83 L.Y.)

STF 701: White and ruddy / rusty. ~6”, 1 delta mag.
05H 23M 18.50S -08° 24' 55.9" P.A. 139 SEP 6.3 MAG 6.13,8.09 SP B8III DIST. 122.7 PC (400.25 L.Y.)

STF 982: Bright orange and slightly red star, 2-3 delta mag. [AB seen; AC and AD fainter and wider]
06H 54M 38.63S +13° 10' 40.1" P.A. 142.5 SEP 7.32 MAG 4.75,7.80 SP F0VP DIST. 25.63 PC (83.61 L.Y.)

Ho 342: Split when seeing stills; orange A and yellowing B, 1.5-2”
07H 02M 50.54S +13° 05' 21.7" P.A. 87 SEP 1.1 MAG 7.99,8.71 SP F5 DIST. 212.31 PC (692.56 L.Y.)

STF 1007: Pretty equal white finder split; one star with one companion seen through eyepiece? [AC and AD pairs]
07H 00M 37.12S +12° 43' 24.2" P.A. 300 SEP 14.9 MAG 7.43,11.40 SP A2V DIST. 280.11 PC (913.72 L.Y.)

Eng 28: Pretty, wide equal finder split, white, nice field. [BUP 96 3.5 delta mag very wide BC]
07H 08M 00.24S +15° 31' 42.9" P.A. 99 SEP 171.9 MAG 7.86,7.74 SP G0V DIST. 46.75 PC (152.5 L.Y.)

Wei 14: Right triangle. B fainter, almost need averted vision. Third more steady and wide.

Ho 346: Orange and much fainter blue B, ~10” 3 delta mag. Nice! [WAL 51 is AC, 6.25 delta mag!]
07H 25M 54.13S +18° 08' 51.0" P.A. 58 SEP 13.5 MAG 7.04,11.70 SP G5 DIST. 324.68 PC (1059.11 L.Y.)

STF 1090: Pretty finder split, equal white. Is a 2+1 with 2x fainter. [AC, BC wider and fainter.]
07H 26M 27.33S +18° 31' 00.8" P.A. 98 SEP 60.7 MAG 7.27,8.17 SP F2V DIST. 112.23 PC (366.09 L.Y.)

STF 1083: Equal wide, white.
07H 25M 35.30S +20° 29' 42.6" P.A. 46 SEP 6.8 MAG 7.32,8.13 SP A5 DIST. 132.45 PC (432.05 L.Y.)

NGC 2392, Eskimo Nebula: Bright central star, inner ring with lots of mottling; green larger round, diffuse halo with soft edges. With OIII, central star is gone, but nebula is a little more apparent, with same features.
