NGC 1535 Cleopatra's eye SA100 spectrum

Here's a bit of fun. NGC 1535, Cleopatra's eye planetary nebula spectrum captured with the SA100.

The SA100 of course can only capture large bands at [OIII] 5007 and H alpha 6562, as the zero-order image of the nebula itself is c 25" across (30 pixels with my setup). But these are pretty clear :-)

Good catch!
Well done..
Certainly shows why these nebulae show up so well with OIII filters!
