[Aavso-photometry] newbie filter question

[Ian Bacon]

Hello,

I have been pestering people on the SBIG discussion group with a few  
questions, and was directed here for follow up questions.

By way of background, I have been carrying out visual variable  
observing for years (BIX), but have now decided to go ccd. My scope  
is a 10" LX200GPS. I plan on buying a SBIG ST-7, a 10 position filter  
wheel, a F5 focal reducer (NextGen), and Optec focuser.

My specific question is this, what are the best filters to buy for  
variable use? I would like to get a complete set (UBVR, maybe even  
I). I realise that in the beginning I will not use this full set, but  
I plan to expand my observing as my experience grows.

So, any thoughts on filters (or any other part of my setup)?

Thanks for any assistance.
