Description

This was a first attempt at a short exposure, Light Polluted IFN imaging.

This is not a clean image. It was strictly processed to bring out the IFN. The shot was 390, 30 second subs. It was taken in my Bortle 7, Red Zone front yard on the east coast of Florida. I still need days of exposure time doing only 30 second exposures to get a clean image.

It was taken with a Sony Nex-5 at ISO3200 and a Minolta 135mm at f4.5 on a Ioptron SmartEQ mount.

Rev2 Reprocessed same data with slightly different noise and background techniques.
