These area pn the Mars ;100 deg to 200 deg

lens (right drawing)

D=100 mm F=640 mm hand
made Refractor (achromatic lens) PL6.3mm+2barlow (mag 203 )
I've changed my Short focus Achromatic refaractor
to be able to use with quality barlow lens .The result is good .I can see
the patterns more clearly like above drawings.
