Personal Rating (for this aperture): B/B+
Fairly large and easy to find in 8x32 binoculars, but mistook for
NGC3532 for awhile until checking in scope. Hint of nebulosity in
binoculars and telescope wtih the UHC filter but...
With the UHC filter I found it to be a very large elongated streak of
nebulosity split in two parts N and S. However, I was not seeing it as
it is depicted in photos, I was not taking in it's full extent,
probably because it was so low in the sky, only around 10-15 degrees
up, in the haze and local light pollution.
Nebula was most pronounced in the north part, with a very obvious dark
lane running up from the south, and others criss-crossing e-w
noticeable with averted vision. A bit larger, but not as impressive as
M42 in these conditions.  There was a loose foreground cluster
involved coincidentally.
Thanks!
