ASTRO: Another Sharpless: SH2-54 in Halpha
this is 4 x 20 minutes of halpha from the stinger cassegrain at f/7.2
roughly. It was shot using the 4.5nm CS Ha filter and FLI IMG1024S Dream Machine from my backyard in Castro Valley near San Francisco I shot a bit of oxygen last night but the clouds shut me down after two frames and one was foggy this is going to be another "project": I can just tell... http://www.narrowbandimaging.com/sh2...s4_ha_page.htm

Richard,
that is a very intersting region, lots of structure. Can't wait to see the final version (in one or two months).
