When blending the colour print taken in 1989 with the 2007 image, I noticed a star at the centre of field had moved significantly
during the 18 years between images.
Thank you to Rob McNaught for finding the ID of this
star and supplying the following info:
Star is LHS 2085 (that's star 2085 in Luyten's proper motion catalogue)
0.847"/yr PA 323.6 12.8R, 14.3 PhotoBlue
Revised Luyten (Bakos 2002) gives 0.70"/yr PA 327.94 12.8R, 14.3B
Tycho gives mag 11.8V
Clicking on the "Simbad" link at the end of the Bakos listing gives
