More planetary nebulas
SPX350 F9.1, 2x Powermate, ASI290, Baader RGB, Astronomik UHC filters.
I have some more planetary nebs, small and unloved. NGC 5189 is pretty big at 3.1 arc mins diameter in Musca and does not seem to be imaged much despite its interesting shape and colour.
NGC 3699 in Centaurus was imaged in bad seeing and displays a ghostly presence, irregular in shape.
NGC 5307 is very small and forgettable but perfectly formed at 18".
NGC 5882 was imaged in bad seeing but shows some structure, it is found in Lupus at 20".
NGC 6153 was imaged in good seeing, did not show much colour so needed lots of saturation, detail came out nicely. 24" diameter.
IC4406 the retina nebula has a bright mottled core and very faint extensions.
These ASI290 exposures are from half sec to 3secs
Regards, John
