Thanks again everyone

Yes the camera was bought from Hutech, the IR filter replaced by clear glass. I could have got one with an extended IR filter that still allows in all the HA light, but thought Id go the clear glass option so as to experiment with infra red work. To stop unwanted IR light during astrophotography, I use a screw in 2 inch Idas uv/ir filter, in addition to the UHC-S nebula filter.
I must try the odd and even summing and see how the noise goes too, good idia

Also the
Deconvoloution.
I didnt think a strong noreaster would bring about such a dark sky, but both magellinic clouds were readily naked eye visible, some times none can be easily seen even at max height.
