spider diffraction

I bet you didn't think of this kind of spider diffraction:

Found on Aladin Lite (DSS2 survey).

It seems they sent starship Enterprise to investigate.

Spoiler:

this is actually diffraction from spider vanes, and not from an arachnid.

Dont, I once has weird issues with my subs on a newtonian, when I opened the filter wheel discovered a small spider had got inside and spun silk over the filters destroying several nights of imaging, simple fix, go to an SCT and frac and keep them sealed up.
