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.

I own a Thousand Oaks H-Beta 1.25" filter, I like it, works well. I also own an Orion 2" H-Beta filter, I cannot recommend it though.

You can buy either the Lumicon or TeleVue with confidence as they are both premium filters. I’ve personally used the Lumicons for a long time and have a complete set of those. They are very good.

 

I expect you are going to have some good success seeing the Horsehead with that setup. The first observation is the toughest, and it gets easy after that. I’ve seen people spend years looking at it without seeing it, and I think one of the reasons is that it is much larger than you expect. That’s my tip to remember.

+1 for the Lumicon and Televue hydrogen-beta filters.  They are the best.  Your scope and the filter will show the Horsehead in a good dark sky.  However, as Allan pointed out above the first time is the hardest.  The Horsehead is a dark blob against a not quite as dark background.  It can be very difficult to recognize the first time.  Get a star atlas and familiarize yourself with the star pattern surrounding the Horsehead.  You need to be able to find and identify this pattern.  Then you can concentrate on teasing out the slightly darker blob.  Check out Don Pensack’s Nebula Filters Buyers Guide spreadsheet.  Especially important is bandwidth (narrower the better).

To find the horsehead nebula use a wide field low power with the H-Beta filter for a brighter image, it makes it easier to find IMHO.

Why can't you recommend the Orion?  I've seen that Don did recommend the sample that he had.

I find that in the Orion filter everything appears green, including the horsehead nebula, it just doesn't seem natural to me.
