Horsehead and Flame Nebula

Horsehead and Flame Nebula
This is a combination of the broadband RGB from late-Feb 2013 http://www.iceinspace.com.au/forum/showthread.php?t=103484
and the currently acquired images in Ha. Total Ha is worth over 2h in 2-3min subs @ Iso1600.
While using the NBRGB script I tried several options of the RGB-to-Ha ratio and in my opinion, rather conservative, I think, 0.5xHa was the value I liked the most.
Cam: EOS 60Da + Ha Clip Filter
Scope: ED80TCF
Guiding: PHD guided CPC925
Stacked, processed and NBRGB-combined in PixInsight …

Wow, certainly look good to me Ian. A question please where/how do you do RGB + Ha combination in PI? with ratio of Ha

David, in "standard" PI there is nothing, but in PI forum you can find link to NBRGB-script that was specifically written to combine Ha, OIII and RGB images.
There you can set the ratio between Ha and other image's component(s).

Thanks Mike.

As far as the NB-RGB combinations go - all is done for you by the PI script !!

Good result Ian!

Combine worked well.

Cheers,

Justin.

[IanP]

Thanks Justin,

Yes, I’m happy with the Ha addition to the broadband RGB produced by 60Da.
I was thinking whether you can use the Ha filter with your unmodded 1100d, but that combination may not produce reasonable outcome ..

[multiweb (Marc)]

Wow! That looks terrific. Really cool.

Really good Ian. You did a good job of taming Alnitak.

Sweet shot! Love the colours and details in the flame.

[IanP]

Thanks Marc,
Thanks Geoff,
Thanks cazza132 ..

I aggressively decreased the HIGHLIGHTS and then (trial & error) found the balance between the broadband RGB and Ha.
