Somewhere Mid Disk in CaK - 14th May

cak-mid-colour

The seeing wasn't as good today, and I was pushing it at 100mm aperture, I would have got better results at 80mm despite taking many 4000 frame avis and hoping to net something good.  The shrpeness is down on these images.  Take with the 100mm f10 with 2.7x telecentric, home brew CaK filter and the FLIR IMX174 camera.
