Hi,

I have finished reduction of two images of Tonny Vanmunster and the one by
Arne Henden (many thanks for them). Positions are based on nine GSC 1.2
reference stars with rms resudials 0.09" in R.A. and 0.12" in declination.

The final position for RY Ser is 17h 23m 07.199s  -12o 48' 09.43"

This is a weighted mean from the three positions - one from each image
(Vanmunster's have assigned weight 1 and Hendens weight 5).

Best regards, Jan
