Thanks hugely for the reference Mike. Fascinating. If I've understood correctly, the "wing" on Thor's Other Helmet is where the supernova ejecta have broken through a thin patch in the pre-existing interstellar medium, and a lobe of star-guts is hurtling toward us at great speed. Hope I've got that right. Must read it again.

On a reassuring note, the Placidus shot, at 1/6 the altitude, 1/8 of the aperture, 1/64 of the light gathering power, and not much of the budget, is (as the 70's pop group Yes put it) no disgrace, and yours is no disgrace either!
