Re: (IAAC) IC 432 - 17.5inch F/4.5



Thanks for another two intriguing observation posts, Yann!
I was particularly interested in your use of a light blue(?)
color filter to enhance the contrast of the faint reflection
nebula IC 432 in Orion! What other "color" filters have folks
on the list found to be useful for bringing out these elusive
reflection hazes? Also, do you happen to know the (rough)
transmission characteristics of that W38A you used - was it
a special high-transmission filter for visual use?
Clear skies!
