Date: 18/19.10.2003 22:20
Instrument: Newton 406/1830 mm
Magnification: 146xFilter: O-III
Field: 21'Seeing: 3
Background sky: 3NE lim mag: 6.2
Visuality: IIHeight: 55°
Weather: weak northern lights, 47% moon has just risen, -2.5°C
Description: Much larger than I expected. Southern parts are out of the field because of too high magnification. A huge crescent shape is easily seen and two smooth spots are apart of the main nebula. Few stars are involved within the nebula. O-III filter helps a lot.
