N203/1200mm Orion SkyQuest
Object: NGC 2346
Obs. place: Sotunki, Vantaa, Finland
NE Lim.mag: 6.0m (SE)
Background sky: 2-3
Weather: -17°C, very cold, chilling wind from N, green flash-aurorae very low N.
Description: Pretty bright, large planetary in a moderately rich field.
Found @ 38x without a fuzz. At first, the planetary appers as an annular, slightly
NE-SW elliptical haze with several 14th magnitude stars nearby. There's also
two very faint brightenings in the NE and SW edges of the halo. After several
minutes of watching, O-III filter starts to show some additional details: NE
and SW edges come very sharp and some fainter nebulosity can be suspected outside
the inner ring. The elliptical shape is almost gone at 360x + O-III and the
halo appears mottled. The ring structure also becomes broken from the NNW corner.
Slightly triangular or hourglass-shaped but very difficult. Central star not
seen (mag 11 my ass).
Notes: Sketch rotated (N up). Finer details not added to the sketch.
