Notes: First session with newly aluminised mirrors. NGC 5996 is the brighter and shows itself as a barred spiral without too much difficulty – a consequence of it being a starburst galaxy perhaps. The companion precedes NGC 5996 and needed AV. I saw it only once. There is a bright star, 35 Ser, at the edge of the 17mm field. Unable to see any bridge between the two galaxies. Viewing curtailed as the pair moved behind trees. |
