Cave Nebula narrowband with rgb stars

[Jessun]

Here's 37h05m total integration on the Cave Nebula.

The cameras are 3 Atik 460ex with EFW2 populated with 3nm Astrodon NB, and Baader LRGB filters.

I capture with these three cameras at the same time using three SW 80ED on an AP1600GTO.

12h HA, 11h30 SII, 9H30 OIII - 15 m subs, 1h35m R and G and B, 5m subs.

Processed in PS CS5.

Thanks for looking!
