Description:
117X - A small blue-green glowing spot without filter. Best with O-III filter,
but almost as good with UHC filter. The PNe looks granular.
203X -  The O-III filter dims the PNe and little is seen. The UHC filter dims
some, but the central star is well seen. The best view is without a filter. 
The central star is steady, the PNe is not round, but 4-lobed like a fat fuzzy
cross. The Lobes are brightest with the area between the lobes, being dim, but
with a definate glow. The granular apperance is not seen at higher powers.
314X - NGC4361 s too dim to show any detail with the O-III filter and the UNC
filter does not help any. The central star is well seen, but the PNe is mostly
a dim ghost with unfilterd view.
