Hi Rod,

Did you use a filter when trying to observe this target at Coona? I am guessing, not !! You really need a good filter to get the best of this target visually, particularly the inner section of the nebula. Which you can get in a smaller scope than a 20". A good narrowband filter (UHC), or a good OIII filter work almost equally as well on this target. The Astronomik UHC filter does exceptionally well on it.

Cheers,
John B
