On the same images I have taken of epsilon Aurigae I have also found three weaker variables that I have analyzed. They are the cepheid RX Aur and the eclipsing variables SX Aur and TT Aur. SX and TT at magnitude 8-9 are little to faint for the dynamic range in the images, but the phase yet shows pretty well. I estimate that the error for these stars is +/- 0.10. RX is a bit brighter at magnitude 7 and for this star I got a nice graph and an error of about +/-0.05. The graphs and info in swedish is at: var.astronet.se/results2.html

Hi Thomas! Cool! I enclosed a finder chart which includes eta and zeta Aur, so it's quite easy to locate e.g. on your existing DSLR or CCD frames. CS Heinz

And here is an extract from one of my images with star names inserted. This is as an example how my pictures look like.
