Description:
117X - NGC7094 Planetery Nebula is starlike, blinks with O-III filter, but it
is very small and difficult with averted vision. The central star dominates the
view masking the nebulosity. The UHC filter increases the contrast and the star
is some brighter.
203X UHC filter shows PNe easily with averted vision, but only suspect with
direct vision. Slow panning reveals a ring structure with a faint star
superimposed on the disk at the N-E. Central star is prominent.
314X The Ring is readily seen with averted vision and O-III and UHC filter, but
quite dificult with direct vision. The star in the N-E appears to overwhelm the
faint ring adjacent to the star creating the appearance of a break in the ring.
Or it could be weak in that area as the S-W area oposite is some weaker than
the remainder of the ring. The central star is dominant.
628X- The PNe is not detectable using all the tricks in the bag, but the
central star is easy as well as the star in the N-E, but it is quite dim at
this power.
