I did notice that the image is predominately green when streched the brightness, not sure if the filters are causing this green cast, will attempt Orion again without filters to see if the green persist - just waiting for the clouds to clear.

Fine first image Eddie
You'll find that Gain:1 and Offset between 60-70 will get you the best results. The green cast can be caused by light pollution but also because the camera has 2 green pixels for 1 red and one blue in the bayer matrix. If you use the clear nose piece you'll get a green tinge even under very dark skies. But you can fix that by offsetting channels.
