Description: My first successful view a month ago was
difficult. This time the nebula jumped out brightly. Faint
"arms" visible without filter. The use of high power without
losing substantial contrast, unless filter employed, was
delightful. The filter seemed detrimental at any power,
especially losing detail at higher ones. This concurs with
the supplemental post by Lew Gramer in response to the M45
report from Todd Gross. It would appear that visual
magnitude is not absolute in determining quality seeing,
since my August viewing seemed visually "better" - indicated
by a more prominent Milky-Way.
