Abell 4 (PN)

DSS
Image source: DSS II (blue) - 5×5'
Name: Abell 4, PK144-15.1
Type: PN
Constellation: Per
Coordinates: 02h45m23.67s / +42°33'04.94"
Brightness / Size: b15.6 mag / 0.4x0.4'
120mm f/5, 75x + UHC, Bortle 4, SQM-L 20.9
Tried also at 75x with [OIII] filter without any success.

FAILED
152mm f/5.9, 60x + [OIII], Bortle 3-, SQM-L 21.3
Also nothing visible at 100x with UHC filter.

FAILED
8" f/6, 80x + [OIII], Bortle 4, SQM-L 20.9
Small, faint, evenly bright, round disc.

MODERATE
8" f/6, 80x + [OIII], Bortle 3, SQM-L 21.3
Small, round, evenly bright nebula.

MODERATE
12.5" f/4.5, 96x + [OIII], Bortle 3, SQM-L 21.3
Evident with averted vision, small, round, evenly bright. Almost visible with direct vision.
EASY

IC351 (PN)

DSS
Image source: DSS II (blue) - 5×5'
Name: IC351, PK159-15.1
Type: PN
Constellation: Per
Coordinates: 03h47m33.14s / +35°02'48.51"
Brightness / Size: v12.3 mag / 0.1x0.1'
8" f/6, 96x, Bortle 7, NELM 5.0
At 37x stellar and well visible with averted vision, at 96x slightly extended and visible with direct vision. At 171x still very compact, roundish, extended. Overall fairly bright.
EASY

IC2003 (PN)

DSS
Image source: DSS II (blue) - 5×5'
Name: IC2003, PK161-14.1
Type: PN
Constellation: Per
Coordinates: 03h56m22.03s / +33°52'29.27"
Brightness / Size: v12.6 mag / 0.1x0.1'
8" f/6, 171x, Bortle 4-
At 37x stellar, at 96x slightly extended with averted vision. At 171x round, quite compact, but extended. Overall fairly bright. The nebula is located within a group of brighter stars, so it can be easily confused with a star. High magnification and detailed chart helps.
EASY

M76 (PN)

DSS
Image source: DSS II (blue) - 5×5'
Name: M76, NGC650, NGC651, PK130-10.1, H1.193, Little Dumbbell Nebula
Type: PN
Constellation: Per
Coordinates: 01h42m19.95s / +51°34'31.15"
Brightness / Size: v10.1 mag / 2.7x1.8'
B 40mm, 8x, Bortle 4, NELM 6.1, SQM-L 21.0

FAILED
B 70mm, 16x, Bortle 3, NELM 6.4
When knowing the exact position fairly easily visible with averted vision as quite small, nearly stellar brightening.

MODERATE
55mm f/9.1, 41x, Bortle 6-, NELM 5.0, SQM-L 19.0
At 25x without filter extremely faint, roundish brightening. With UHC filter significantly higher contrast, but still faint. At 41x faint, evenly bright, roundish.

MODERATE
70mm f/5.7, 50x, Bortle 6-, SQM-L 19.1
Relatively well seen with averted vision. Small, evenly bright with a rather rectangular shape. With UHC filter almost visible with direct vision.

MODERATE
70mm f/5.7, 66x, Bortle 3-, SQM-L 21.3
At 10x rather inconspicuous and very small. Well visible with averted vision. At 66x the nebula appears slightly elongated with a square shape. Barely seen with direct vision.

SKETCH

EASY
4.5" f/8, 75x, NELM 3.9+
Almost full moon with an angular distance to M76 of about 60°: Only visible with averted vision, relatively small, roundish, diffuse, structureless. Overall quite faint.

MODERATE
4.5" f/8, 100x, Bortle 7
At 28x a small, diffuse brightening, which can be seen quite well with averted vision. At 100x slightly elongated, whereby the shape appears irregular.

EASY
120mm f/5, 40x + [OIII], Bortle 6-, NELM 5.0+, SQM-L 19.0
At 40x with OIII filter conspicuous, slightly elongated with rudimentary visible arcs on the NE and SW side. Without filter rather faint. At 100x the arcs are quite well recognizable, especially with UHC filter.

EASY
120mm f/5, 66x, Bortle 4-, SQM-L 20.9
At 40x just a small, faint, round brightening. At 66x the arcs at the NE and SW end are visible. I did a sketch at 100x.

152mm f/5.9, 150x, Bortle 4-, SQM-L 20.9

SKETCH

EASY
8" f/6, 37x, Bortle 4, NELM 6.0+, SQM-L 21.0
SQM-L 20.8: Barely visible with direct vision, evident with averted vision, relatively small. Shape of a dumbbell perceptible, otherwise oval. I only had a short look, because the comet C/2014 Q2 (Lovejoy) was the main target.
