EGB 6 - an extremely faint PN in Leo

[gorann]

EGB 6 is a very faint planetary nebula in Leo. It was catalogued by Glenn Ellis, Earl Grayson and Howard Bond in 1984 after looking through prints from the Palomar Sky Survey. It is big (8 light years wide) and relatively close (2100 ly), so it is old (probably 50 000 years) and therefore so very dim.

Even @Petergoodhew, who of course have imaged it, calls it extremely faint. I imaged it under 50 - 70% moon, so not ideal, but the RASA is a photon bucket.

Dual-RASA8 rig with ASI2600MC. IDAS NBZ filter on one and Baader high-speed Oiii on the other. 102 x 5 min, so totally 8.5 hours. Processed in PI and PS including the XTerminators.

Cheers, Göran
