IC 1805, IC 1795, NGC 896 and NGC 1027 area, with Canon 20Da and TMB 92mm f/5.5 apo refractor with Borg 0.85x reducer/flattener at f/4.6, for stack of 4 x 15 minute exposures at ISO400. Taken on an excellent night, October 1, 2008, from home.
The Heart Nebula, IC 8105, in Cassiopeia, with nebula NGC 896 at upper right and star cluster NGC 1027 at left of centre. This is a stack of 15 x 5-minute exposures with the Nikon D810a as part of testing, at ISO 1600, and with the TMB 92mm apo refractor at f/4.4 with the Borg 0.85x field flattener with the extra spacer ring. However, edges are still soft. Taken from home Nov 29, 2015.
