Yep, type in R ARA. To get some mags with VSP, change the FIELD OF VIEW box to 420 (7-deg). Also, change MAGNITUDE LIMIT to 10 so you don't get too many stars showing, and select the YES option for lines to magnitude labels. This will bring up some comp stars - not great for R Ara for visual observing (OK for photometry) - R Ara varies from mag 6.17 to 7.12 - but it looks like all you've got from AAVSO. I did run it out to 15-deg for no benefit. Older RASNZ charts may have a much better range of comp stars but I'm not sure how you get them. I'll look into it.
Joining AAVSO costs money, but you can register as an AAVSO observer for free, and get most of the benefits. You get a 3-digit observer code. Mine is KBJ.
Good luck Orestis! Keep us informed of your progress.
