|NGC 6543, 10 inch, 810x|
Telescope: TEC 250mm F/12 Maksutov Cassegrain
Eyepieces: Televue Ethos 3,7
Transparency: 4/5, 21.7 SQM
Notes: Another difficult planetary. High surface brightness, but very low contrast. Very faint extensions at the sides. Not all the "bright" zones are regular, they are formed of bright arcs, and lower contrast parts. High power, patience and perfect seeing are necessary.
