Hello Roy,
There is no formal way to join the VSS, as long as your interested in VS we’ll welcome you!
To submit observations to the database, you will need an observer code and login details. Have a read of this and it will advise how to go about it…

I’ll leave it to one of the CCD observers to comment on your set-up, but it looks fine to me.
Don’t forget the VSS Circulars – free to everyone! https://britastro.org/vss/VSSC_archive.htm
