IC405 presents a reasonable amount of SII and I shot 45x600 subs of SII. But searching for the color mix I wanted, HOO ended up feeling right. That HOO mix was laid over a luminance channel of straight Ha.

This is one of my first sets of data with the ASI1600 and FQS106 mounted on top of the Planewave. The Planewave was used to guide via the OAG on the Planewave. That is probably not ideal, but with an image scale of 1.46 on the FSQ/ZWO it seems to be fine.

To be sure, the ZWO performs much better on narrowband than broadband. This is due to the lack of reflections with NB.

Linear processing in CCDStack, including sharpening. Post-processing in Photoshop, including unsharp masking, and color enhancement. Topaz de-noise 5.1 was also used.

SII used as an overlay layer [finally got that in there ;)] and Camera raw clarity used on mid-tones, 100-150 + feathering
