Orion H-beta filter-advice

[Rhushikesh-Canisminor]

Hello!

I'm currently in USA and thinking about getting Orion H-beta filter 1.25", to kind of complete my filter gear. (Already have lumicon UHC and O-III...both are giving nice views!) Any advice for H-beta filter? 

Price here is around 95$, including taxes. Back in my hometown it is doubled! So if it's worth then I'll go for it!

Thanks!

The best guide to the usefulness of each filter type is this one from the Prairie Astronomy Club.  The H-beta is listed as best for about 17% (16) of the 95 nebula compared.  Thus, you have to make your own choice if it is worth dropping about $100 to get the best view possible of less than 20% of nebula.  Diminishing returns.
