I originally shot SH2-112 and 115 as a
single frame. I wanted to pick up some of the flying buttress to the left, so I decided to make a mosaic. I only had time last year to add one panel, so I ended up with a really
wide aspect 1x2 image. This year I've circled back and added a couple more panels to get it back to my usual aspect ratio. Unexpectedly I picked up a new soap bubble planetary nebula PK086+05.1.
The previous mosaic I shot separate RGB for the stars. For this mosaic, I'm skipping the RGB stars. Instead I created a HOO image for just the stars. I find that using SPCC configured with photon flux for the white balance and narrowband filter mode, the resulting stars are quite close to what I was getting with the RGB stars. There's the occasional blue star that is more prominent in the RGB stars, but I feel it's not worth the hassle capturing RGB frames, especially when doing mosaics.
