For the first time since acquiring the Starizona Night Owl 0.4x focal reducer I decided to image with the Celestron F/6.4 focal reducer without a light pollution filter(LPF). These images were acquired in 14 to 15 radiance area in increasingly light polluted Frederick, MD vs the 0.5 to 1.0 radiance darkish areas where I image in Harvard MA and in Northern Maryland. Except for the NGC6946 which was imaged with 30s subframes all imaging was done with 15s subframes. I'll be revisiting many of my DSO favorites imaging without the LPF to see if an improvement in signal to noise can be achieved. Update: Globular clusters are reprocessed for less contrast and saturation.
