Description

Had to throw away a third of my sub-exposures on this one - had trouble with my tracking. My Declination was OK but my RA would wander off and need some heavy correction.

I accepted all images with eccentricity less than 0.75 just to get enough sub-exposures to create this image. Normally I choose 0.70 as my boundary, but that would have rejected more than half my frames.

Anyway, here it is.....seemed to work out OK in the end
