NGC6888 24/7/11

[Glider]

A few weeks ago I posted 2 hours of Ha on NGC6888. Since then I've added another 3 hours of Ha and 4 hours of OIII.

All 10min subs from an Atik 16ic through an ED80. finderguider/SPC900/PHD guiding on HEQ5 Synscan Pro.

Stacked with flats but no darks or bias in DSS, then processed in CS3.

I've followed the Ha Red, synthetic green, OIII blue approach.

Hey Glider, cool image. I love the colour scheme but can you say how you make the synthetic green? It looks really spooky!

Nice one.

Hi, basically I have followed this website, Cannistra Bicolor Narrowband Technique.

Cheers! Great link. I haven't used my OIII filter yet but, clouds permitting, I will this week.

Thanks for the article.

Looks nice in bicolour does this one and youve got a heck of alot of data in there especially the fainter blue outer regions, great image.

Easy these Atiks arent they;)
