At last , Jupiter settled to give some x150 magnification views, lovely crisp bands and shading. An aperture mask is as good as anything to take off any brightness. Taken to using a large notebook instead of sheets of paper .
Hercules and Serpens are well placed. M5 is a spectacular globular cluster, however the night belonged to “Graff’s Cluster”, IC 4756. A beautiful scattering of stars , filling the eyepiece.
As it didn’t get much darker to midnight , I returned to some of the finest binaries in Hercules. OΣ 341 gives a lovely view of this multiple group , almost like an open cluster. Sarin is probably my favourite here. Expect to use some averted vision to get some of the faintest companions in summer skies. A bit more magnification will darken the field of view, under
clear skies ! Nick.
