I was able to capture 5 1/2 hours worth of Sii data last night, the most data I've ever collected in one night! Adding it to the previous
Ha and Oiii data produced the image below which has been rotated and slightly cropped. The Sii added some nice depth to the image. The original image was 4656x3520 pixels. The final image is 3287x3287 pixels. North is down in the image and East is left.
