| Popis: | An optical polarization map of the GGD 30 nebulosity shows that, although it shares many of the morphological characteristics of classical cometary nebulae such as NGC 2261/R.Mon, it differs in that the star-like knot at its head is not the illluminating and exciting source as previously assumed. The knot is reflection nebulosity and the true source, completely hidden from direct view at optical wave-lengths, is located some 6 arcsec east of the knot |
