I am currently looking at this nebula with my 20" at 256x and the central star is quite easily visible with direct vision. Probably due to the fact that nautical twilight has just ended and the contrast of the nebula with the sky background is still pretty low. Back to observing now.
Edit: at 320x with SQM 21.2 I can see the central star with direct vision but much harder than earlier tonight. With averted vision the central star disappears.
Clear skies, Wouter
