Re: New shot: IC5146 Cocoon Nebula

Serena,
I have an older shot of the same nebula/cluster taken with the wider
field of view of the FSQ-106n at f/5. The camera was essentially the

Note the reddening (if that is spelled right, it is a miracle) of
the stars that is prominent around the nebulosity. There is a lot of
dark material there. Fascinating stuff,

~john

Hello John, I guess because of the blooming you stacked a number of < 60 sec exposures. Or did you remove the blooming in post-processing. Easy for me to...	serena_aussie	Aug 4, 2004 12:24 pm
Hi Serena, Is it winter now, yet ;-) We are in a heat wave here: 26.5C out now and it is only 9:30 in the morning! Thanks for the kind words on the Swan...	John A. Blackwell john_a_black...	Aug 4, 2004 1:37 pm
