About this image

The autoguider still doesn't work so the stars were trailed slightly.  The simg program was used to extract the stellar PSF and then 10 iterations of Richardson-Lucy deconvolution applied.  The resolution was improved markedly but a ring-shaped artifact can be seen around the brightest 3 or 4 stars.
