An Owl in the moonlight

[DaveS]

I was searching for a target that would fit in the FoV of my ODK rig and hold up under moonlight. After a mosey round in Stellarium I came up with NGC 457, the Owl (Or Dragonfly) cluster.

I took 12 subs each of 300 sec Red and Green, and 525 sec Blue (First order G2v calibration) Only 11 of the R and B made it through AstroArt's QC, but all 12 Green did.

After stacking I cropped off the dither edges and applied a Gradient Reduction followed by star Erosion to shrink some of the bigger stars.

Trichromy was followed by a DDP and Richardson-Lucy deconvolution with a slight Histogram Stretch to take the background down a touch. Saved as a JPEG

Phew!
