My latest image of this southern variable nebula came through on Friday. When I compared it to one taken just 23 days earlier it was clear that there had been some small changes in the nebula. I re-processed both sets of images in the same way and then compared them side-by-side. The negative images below show the changes.
The central region has brightened but the small knots of nebulosity extending eastwards have faded. A bigger version is on the Orwell AS web forum: http://forum.oasi.org.uk/viewtopic.php?f=6&t=43
This object is certainly well worth observing regularly to monitor its long term behaviour.
Mike.
