Description

Experimenting with new CLS filter on a brighter DSO target from heavily light polluted backyard. Surprisingly warm and clear night but with strong jet streams affecting seeing and wind gusts troubling autoguiding and ruining many subs. This CLS filter throws the color balance off big time making post processing a challenge. Will need to do few more iterations to get it better aligned.

Unmodified Canon 1100d ISO 1600 and Altair GPCAM2 224c guidecamera. Lights: 17x180" + 31x120" + 19x60s. Calibration: 40 flats, darks: 20x180" + 20x120" + 20x60", 20 dark flats, 20 bias.
