Description:
138.5X - The PN is a small bright blue-green disk with a hint of central star, but no other structure.
314X - The bright disk with an easy central star. The PN's disk appears mottled
with the central area brighter than the remainder. The edge is fuzzy and
indistinct with a rim of fuzzy spokes. This dtail is only visable duing brief
moments of better seeing. The O-III filter blocks the central star, but
increases contrast. However the detail is still seeing limited.(Not good)
