Skies were partly cloudy and seeing was fair. Some ringin on images
which I haven't had
For ages. Images were approx 1700 frames stacked for each.

Seeing one night after opposition was a poor show, so I have countered by using the RRGB technique (i.e. using the R filtered image twice, as both a component of the colour image, and as a luminance). The results are quite pleasing.
The region of the STB about I=290 can be mistaken by the casual observer for the GRS hollow without the spot, particularly on-screen.
