Description:
134X-NGC1535 appears as a round, tiny spot, moderately bright with uniform
brightness and a faint twinkle at the center. It blinks well with the O-III
filter.
254X-NGC1535 appears as a round diffuse object of gray-green color and with a faint, but distinct central star. The O-III filter blocks the central star,
but the PNe appears the same with or without filter.
508X-NGC1535 appears faint, sightly irregular round ring with a centeral star
and some vague darkning in the center around the C.S. The outer envelope which
is very dim is not observed, even with the O-III filter.
This observation is generally disappointing as I have seen this object much
better on many occasions.
