(IAAC) Obj: M 27 - Inst: 24 cm dobsonian, f/6.6

[Tudorica Alexandru]

I did't used any sort of nebula filter, but i usually see different colours than others in nebulae and comets. I saw once on M 27 a green hue, but witht the 9 cm refractor, in +7.45 sky... I see colours in telescope very rare, only three times until now.
Clear skies,
Alex

This was an interesting log, Alex. Were you using any sort
of nebula filter (e.g., NarrowBand, UHC, OIII, or similar),
when you noted the color of the Dumbbell as "yellow-red"?

Clear skies!
