A double set of captures from this morning,separated by approximately 40mins. I used the ZWO CH4 filter (890nm,20nm bandwidth) for near IR as I had found it to show a bit better contrast than the IR685nm.
Unfortunately cloud ended the session early and I was only able to capture 4 sets of data for the later image.
I aligned and stacked 40% of each of the 10 000 frames,before wavelet sharpening and stacking the resulting images (10 and 4 respectively). No derotation.
UV image to go with the IR890’s circulated earlier.
The bright polar regions were very obvious during data capture.

I detected a slight band at 10 o'clock position in the IR image. In UV light,the southern cusp is very bright.
