Thommes Nebula
Thommes' Nebula is relatively recent addition to the group. It was discovered by a Californian amateur astronomer in November 2009 - see
http://www.ifa.hawaii.edu/users/reipurth/PREPRINTS/ms_V900Mon.pdf for details. Although the nebula is not visually impressive, it does illustrate the fact that there are still things out there waiting to be discovered! The star V900 Mon and its associated nebula are in the centre of figure 1 below.
Figure 1 was captured on 11 January 2013 with the SSON 81 cm telescope. Five 120 s exposures. FoV is 11x11 arcmin
