IC434 (BN)

DSS
© DSS II (red) - 80×80'
Name: IC434
Type: BN, EN
Constellation: Ori
Coordinates: 05h41m00.00s / -02°30'00.00"
Brightness / Size: - / 70.0x30.0'
8" f/6, 66x + HBeta, Bortle 4
Easily visible, especially when moving the telescope around. Overall very diffuse, particularly to the west end. A more sharply defined edge on the eastern side wasn't visible to me. Maybe my [HBeta] filter has a slightly shifted filter curve!? The Horsehead Nebula (B33) wasn't visible.
EASY

M42 (BN)

DSS
© DSS II (red) - 90×90'
Name: M42, NGC1976, Orion Nebula
Type: BN, EN, RN
Constellation: Ori
Coordinates: 05h35m17.30s / -05°23'28.00"
Brightness / Size: v4.0 mag / 90.0x60.0'
4.5" f/8, 28x, Bortle 6-, NELM 5.0, SQM-L 18.9
NELM 4.1+: Already pleasant without any filter with some details. With UHC and [OIII] impressive view with many details despite urban skies. Especially the southeastern wing was very great.

EASY
8" f/6, 37x, Bortle 4
Must be seen. Hardly describable ;-)
EASY

M43 (BN)

DSS
© DSS II (red) - 30×30'
Name: M43, NGC1982, H3.1
Type: BN, EN
Constellation: Ori
Coordinates: 05h35m31.00s / -05°16'12.00"
Brightness / Size: v7.0 mag / 20.0x15.0'
4.5" f/8, 28x, Bortle 6
Even under urban conditions with small aperture fairly well seen as faint brightening.

EASY
8" f/6, 37x, Bortle 4
Get lost in the brilliance of the great orion nebula. In comparison fairly small & faint, nearly evenly bright. Located slightly asymmetrical around a 6.75m star. Obvious more easily with averted vision.
EASY

M78 (BN)

DSS
© DSS II (red) - 15×15'
Name: M78, NGC2068
Type: BN, RN
Constellation: Ori
Coordinates: 05h46m45.96s / +00°03'37.80"
Brightness / Size: v8.3 mag / 8.0x6.0'
M78 is one of the brightest reflection nebulas and is therefore even under not so good conditions or smaller telescopes well observable.

B 40mm, 8x, Bortle 7, NELM 4.5, SQM-L 18.9
SQM-L 18.3: The sky was too brightened, so I saw nothing.

FAILED
B 40mm, 8x, Bortle 4-, NELM 5.7+, SQM-L 20.9
Rather compact, diffuse brightening. Barely seen with direct vision.

EASY
8" f/6, 37x, Bortle 4
Quite obvious with slightly irregular shape. Within the nebula the evident binary star BU559 (AC). Towards one side the nebula appears more sharply defined, towards south more diffuse.
EASY

NGC1788 (BN)

DSS

Name: NGC1788, LBN916, H5.32, Bat Nebula
Type: BN, RN
Constellation: Ori
Coordinates: 05h06m54.00s / -03°20'30.00"
Brightness / Size: b5.8 mag / 5.0x3.0'
8" f/6, 37x, Bortle 4+
With averted vision well visible as faint brightening nearby a moderately bright star. At 80x I could see a more fainter, but evident star within the nebula.
MODERATE

Name: NGC1973
Group: Running Man

Brightness / Size: v7.0 mag / 5.0x5.0'
4.5" f/8, 28x, Bortle 6
Barely visible with averted vision as a halo around the "central star".

DIFFICULT

Relatively small, roundish, evenly bright.
MODERATE

Not seen at 37x and 80x, even with UHC & [OIII] filter.

Name: NGC1977, H5.30
Group: Running Man
Type: BN, EN, RN
Constellation: Ori
Coordinates: 05h35m16.00s / -04°49'15.00"
Brightness / Size: v7.0 mag / 20.0x10.0'
8" f/6, 37x, Bortle 4
Evenly bright, slightly curved. 3 stars within the nebula. Evident with averted vision.
EASY

NGC1980 (BN)

DSS

Name: NGC1980, H5.31
Type: BN, EN
Constellation: Ori
Coordinates: 05h35m24.00s / -05°54'54.00"
Brightness / Size: - / 14.0x14.0'
8" f/6, 37x, Bortle 4
Visible as obvious halo around the 2.75m star iota Ori. Seem to be a bit more brighter to one side. However the very bright iota Ori can pretend a nebula!
EASY

NGC1999 (BN)

DSS
© DSS II (red) - 5×5'
Name: NGC1999, H4.33, Keyhole Nebula
Type: BN, RN
Constellation: Ori
Coordinates: 05h36m25.00s / -06°42'42.00"
Brightness / Size: b9.5 mag / 2.0x2.0'
8" f/6, 200x, Bortle 4
Already visible at 80x around the bright 10.3m star with averted vision, fairly bright, but compact. Looks like a fuzzy star. At 200x the nebula is evident with averted vision, appears irregular, slightly shifted around the bright star. The darkening (keyhole) stayed hidden to me. I think, that the seeing has influence on the visibility.

EASY
12" f/5, 200x, Bortle 3, NELM 6.4
Well visible with averted vision as diffuse, irregular nebula around the bright star. The keyhole as small darkening was also well seen.
EASY

NGC2024 (BN)

DSS
© DSS II (red) - 30×30'
Name: NGC2024, H5.28, Flame Nebula
Type: BN, EN
Constellation: Ori
Coordinates: 05h41m43.00s / -01°50'30.00"
Brightness / Size: - / 30.0x30.0'
8" f/6, 66x + UHC, Bortle 4
This observation was some time ago. However I could barely see a irregular brightening with direct vision, which was most evident when moving the telescope around. To keep the bright Alnitak (zeta Ori) out of the field of view I used an 18mm ortho.
EASY

NGC2174 (BN)

DSS
© DSS II (red) - 50×50'
Name: NGC2174, Monkey Head Nebula
Type: BN, EN
Constellation: Ori
Coordinates: 06h09m42.00s / +20°30'00.00"
Brightness / Size: v6.9 mag / 40.0x30.0'
8" f/6, 37x + [OIII], Bortle 4, NELM 6.0, SQM-L 20.9
Evident with direct vision, but overall very diffuse with less defined edges, irregular shape. Appeared about 20 arcminutes large. The shape of a monkey head was not noticeable. Apparent "central star" within the nebula. Also with UHC filter well visible.
EASY

Covers a region of about 10x15°.

B 40mm, 8x, Bortle 4-, SQM-L 20.8
I used all available filters (UHC, [OIII] and [HBeta]) in front of the lens, but no nebula was visible.
