Description

I started this project back in 1991 with the first image taken with a parallel port SX camera then later with and Artemis 285 and more recently with an Atik 383L. All were aken with the same 14" reflector. I intended to take an image every year but...time passes quickly :-) Each image was aligned and layered against a more recent image to give a larger field of view. From 1998 I started to take astrometric measurements to determine the proper motion.

Result RA -0.868" and DEC 10.52" annually

Simbad data RA -0.798" and DEC 10.34"

This is a nice project as it only takes a few seconds to acquire an image..then wait a year!

Only just processed 2018 data found in my files :-) I also have images of other high proper motion stars form a few years ago, will be interesting to revisit them.
