Above is 120 minutes worth of Hydrogen Alpha data captured in five minute exposures with an Astrodon Ha 3nm filter and a Samyang 135mm camera lens on a Moravian Instruments G2-8300 CCD camera.
I then captured one hour in each of the Astrodon R,G and B filters with the same rig as detailed for the Ha image, again in five minute exposures. However, use of the superb Astrodon E series RGB filters produce a nice image and the colours are brought out quite nicely although it lacks a bit of punch and vibrancy.
The bright star to the right is Deneb.
In Photoshop I broke out the red channel and then blended it as a 50:50 mix with the Ha image (at the top of this page) before recombining back into RGB. I also saved a copy of this HaR constituent and then used that as a luminance layer to really make the image pop. I then used a series of high pass filters to reveal finer structures in the image.
