Lacking comps

I'd love to help on this one, but VX Cyg seems to have only one comp in the 30 arc-min field.  Any chance of getting a sequence for this one?

Thanks!

Comps for VX Cyg

Of course it depends on your equipment.  VX (and in fact all the stars on this list) are easily observable visually using a small telescope, or a medium sized one using a long focal length eyepiece.  For all but X Cyg (a binocular variable) I am using a 2 degree chart and a 24 mm eyepiece with my 180mm f/6 Mak-Newt.  That yields plenty of comparison stars.

I don't mean to be lecturing; what is intended is to encourage others to participate!

V

The notice did say, "V and visual observations are requested".   So it makes sense to have a sequence appropriate for CCD photometry as well.
