I have good UHC and Oiii filters in my kit now and I'm ready to add a top quality H-Beta. I see the Lumicon and Teleview 2" filters for around $200 and know both of these companies make top quality products so I'm looking for any factors that would help me decide. If there are other H-Beta filters I should also be considering please let me know. As I've been looking through the information on filters online it seems that filters can vary from year to year or one batch to the next so I'm trying to focus on what I would purchase new in the next month or so.
I'm hoping to use a 2" H-Beta filter for some serious attempts on the horsehead with my 18" dob from a Bortle 3 site this winter but will be using it on the other objects that respond to H-Beta as well.
I would appreciate any experience comparing the currently available filters as I decide which one to purchase.
