Over the past month or so I've been imaging a few different targets. First was NGC 6992, the Viel Nebula. I started with mostly HA but then realised the signal strength was pretty low; I'm still trying to figure out why. I'm not sure if its the camera quantum efficiency drop off, the filter or just the nebula. Anyway, I ended up taking about 2 hours of OIII along with 30 minutes of HA and SII.The result is below:
I plan on returning to the Viel at some point but for now IC 1805 is in an excellent location for some imaging. So despite some persistent clouds and an issue with my autoguider I managed to pick up 15 x 900s OIII exposures. Since I didn't take any HA or SII images yet the image is monochrome.
