Narrowband Imaging the Crescent Nebula

Received my Hydrogen Alpha filter yesterday and we got lucky and had a couple hours of reasonably clear sky.  Although I didnt get as many exposures as I'd liked, my first real attempt at narrowband imaging was a success.  I imaged 2 objects - the Ring Nebula (M57) and NGC 6888, the Crescent Nebula in Cygnus.  The Ha frames that I took of the ring were washed out possibly due to clouds, but the Crescent came out just fine.  

I have never before gotten this much detail on this object before.  In the past, I was able to capture the bright outline with a tiny amount of  the inner nebula.

The above image consists of only 25 minutes of H Alpha and 25 minutes of O3.  Ha was mapped to red, Oiii mapped to green and blue.  I used the Ha stack as the luminance.  This was done with my light polluted backyard, and the Oiii was taken during the last full, supermoon.

Narrowband Imaging

When I bought the G3 at Cherry Springs, I also bought an Oiii filter.  I wanted a Ha filter, but he didnt have any.  I ended up ordering one from Orion last week.

I figured theres no reason to wait for the Ha to come in to start taking narrowband images.  The moon was shining brightly, on its way to become the supermoon which is to occur tonight.  I took this image on 6/19/13 of M97, the Owl Nebula through the O3 filter.

There is some nice detail in this image.  Planetary nebulae are perfect targets for this wavelength filter. 

There is very little Oiii emission in the Crescent Nebula, as seen here...

Note that these were taken under a bright moon.

I'm really looking forward to imaging the crescent with the Ha filter when it arrives.
