This is the best seeing I have had at my dark sky for quite a while but it was still pretty ordinary (about 2.7"). The Eight Burst Nebula is an interesting and pretty object, but is rather small---about 1.5'. Well worth going for if the seeing justifies it.
Camera: FLI Proline 16803 with a 49' x 49' FOV
Exposure: 80 min each of Ha, SII and OIII
FOV: 6' x 6', so there was some pretty severe cropping here.
Blurb: NGC 3132 is also known as the Southern Ring Nebula or, more commonly, as the Eight-Burst Nebula because of its figure-8 appearance through small telescopes. It is a very bright, asymmetric planetary nebula of approximately 0.4 light years across and
is about 2,000 light-years away in the southern constellation Vela. It is receding from us at 49 kilometers per second.
