With the clear nights in Sydney last weekend I got to spend some time on M8 with the Esprit 120. I have finally gotten my OAG working and the improvement in guiding performance was
I went from average RMS of around 0.9" to 1.1" or so with plenty of differential flexure to about 0.4" - 0.5" with no flexure. Good times
Still got a few kinks in the guiding to work out but nothing that seems to materially impact images - I had to discard very few subs from this
