Glad you folks liked the image. The intention of a starless field is to reveal the structure of the ionization front.
I've updated the original set with 3 more hours of data and a few adjustments to the processing. A little more boost to the signal, and allowed for some additional processing while retaining the beauty of the original.
- 15 x 1800s
- 3nm HA AD filter (works just fine at f/3.8)
- STL 11000M (first gen camera, still going strong) the onboard guider was used.
- AP RHA 305 f/3.8. The "All Reflecting Refractor"
Star removal technique (clone and stamp), converted to RGB mode to add a faint blue cold hue to the image, + star spike generator + a bit of an HDR stretch. No sharpening, or smoothing.
Enjoy the ride.
