WO Focal Reducer

Orion 80ED at F/7.5 and at F/6.0 with WO seriesII 0.8 focal reducer
Both images were dark and flat calibrated and minimally processed with ImagesPlus Digital Development to show approx the same background levels. The F/7.5 image is a stack of 50 180 second 400 iso subs. The F/6 image is a stack of 25 180 second 400 iso subs. All subs take with my stock 300D unguided on a CGE mount.
