Iris Nebula, photo by James Canning
This Iris image's apparent mottling is due to the hydrogen haze around
it. You can make out a faint reddish color, especially close to the
nebula. This red color was somewhat reduced by the LP filter I used,
which is a kind of turquoise shade, it's an Astronomic LF3-V4. But the
filter was absolutely necessary.

I imaged with my 5.5 inch refractor at prime focus f/7 with my ZWO 1600 mono camera. The luminosity component consists of 194 sub-exposures of 90 seconds each from three separate nights. The color component consists of 40 green, 49 red, and 64 blue filter sub-exposures of 120 seconds each shot over four nights.
