Dear All
i have been taking time series images of TT Ari and noted a few QSO in the field that I have been imaging.
I stacked a couple of hours worth of exposures- just added with no normalisation. This mimics a continuous exposure of the total time but lets all the stars saturate.
I then plate solved the very dirty image and used canopus software to find the exact coordinate of the quasar on the imae. A very dim spot is at the correct coordinates.
The images are 120sec exposures through a R filter and there were 83 exposures in the stack.
The Quasar is called 0203+150 and is a BL Lac object with a mag of 19.9 according to the
Hewitt catalogue
It has a redshift of 2.1
All in all it is a very long way away.
