Horsehead hunting 2" vs 1.25" H-beta filter\eyepiece combos
Hi,
I'm up in the Blue Mountains with a 12" f/5 Dob and want to try and see the Horsehead this season.
I own a 30mm 82deg ES eyepiece and was thinking of getting a 2" Astronomik H-beta filter to use with it ($300 at Bintel).
However, it dawned on me that I could also just get a 1.25" filter for $150 and hunt down a TeleVue 32mm Plossl to use it with for about the same price as the 2" filter. Currently my longest FL 1.25" eyepiece is a 24mm 68deg ES but I think I want the bigger exit pupil.
Do you think the extra FOV from the 30mm 82deg + 2" filter would improve my odds of seeing the Horsehead? Or would I be better off looking through a narrower FOV made of TeleVue glass?
I already have a 1.25" Astronomik O-III and UHC and a Kson brand 2" O-III filter.
