Description

I found this rather interesting. Clouds, of course, so I tried a Meade 114mm F/8 scope I found at Goodwill recently on a house maybe 1000 ft away (~300 meters), here with a barlow giving it about 1800mm fl.   The results turned out well, so this scope will enter my imaging gear, but the diffraction spikes having a 3 vane spider were "Webb telescope" like. Three vanes=6 spikes.

The newtonians I've had have all had 4 vanes and since the spikes overlap the symmetry resulted in 4 spikes. I thought it interesting to see the six  (which may be about 6 too many for some people).
