Variable stars close to deep sky objects

As a follow up a prevoius thread on the [AAVSO-DIS] list I'll regularly list some interesting variable stars can be found close to deep sky objects.

Recently I started to create a spreadsheet for my planned article "When the visitors come..." in our mountly Meteor. In this preadsheet I list the expected maximum brightness of possible type Ia supernovae in nearby galaxies.

My recent take is: CV Vir. This is a nice mira just 5' from the M87 galaxy, with an amplitude 12.5 - <14.6v and a quite short period: 149.3 days according to VSX. I recommend a chart "e" printed with DSS images via VSP.

One month ago Thom Gandet wrote me "FH Sct is in M26, a very nice looking but small open
cluster.  It may be too far south for yourlocation.  FH Sct is not very active, but I really like looking at the cluster anyway!" - FH Sct is an RCB star with an apmlitude 13.4-13.8p. Chart "e" is recommended.

(To be continued...)
