Type: PN
Constellation: Pup
Coordinates: 07h41m50.51s / -14°44'07.7"
Brightness / Size: v10.8 mag / 1.27×1.27'
120mm f/5, 40x + [OIII], Bortle 4, SQM-L 21.1
SQM-L 20.3: At 40x without filter just a faint, roundish brightening with averted vision. At 75x without filter well visible with averted vision. At 40x with [OIII] filter the nebula appears bright, round, evenly bright and is visible with direct vision.

8" f/6, 171x, Bortle 4+, NELM 6.0+, SQM-L 21.1
NELM 5.0+, SQML 20.2: At 37x visible with averted vision as rather faint, round, small nebula. At 100x evident, round, evenly bright. At 100x with [OIII] filter partly lemon-shaped, center appeared somewhat darker (ring), well perceptible with direct vision. Beautifully embedded in the prominent, star rich cluster M46!

Type: PN
Constellation: Pup
Coordinates: 07h41m54.91s / -18°12'29.7"
Brightness / Size: v9.4 mag / 1.2×0.7'
120mm f/5, 40x, Bortle 4, SQM-L 21.0
