Description

Iris Nebula Widefield in LRGB

Includes the region of the Ghost Nebula (vdb141) on the left, and LBN468 with its dusty knots and Herbig-Haro objects on the right.

Imaged at 2x2 binning then drizzle integrated at 2x before cropping and post-processing. Later downscaled to FWHM=3 (from 4.5) pixels in final versions.

Sky brightness SQM 20.51 with minor occasional smoke and haze.

Update: I decided about a week after posting this photo repeat the imaging of this region, instead with my RASA. It produced the better result: https://www.astrobin.com/v30sgb/
