Description:
At 342x: The inner disk of the PN shows a slightly triangular shape, the outer shell
is round and a little fainter with dark patches visible. The inner part shows some
dark features around the bright central star as well. The details need a lot of time
to be observed but clearly show clearly the “Eskimo-face” structure seen in
photographs. Moments of good seeing help a lot to reveal all the details.
