I see when reading this forum that the Hydrogen Beta filter is highly recommended for faint Nebula, ie, Horsehead.(which in my case will never observe from *here)
The only filter I presently have in my case is a Celestron LPR # 94126A It works fine on M-42 & M-27, but they are larger and brighter..I have in mind locating M-1 Crab. *somewhere near Zeta. Will be looking for it at the 1st. window of opportunity (raining for the past several weeks)
*OREGON COAST. Also what Power x is best suited? I own a C8
have a 35mm. Pan with 2" Big barlow/interface, and a Lanthanum Superwide 17mm. among my better EPs. Any suggestion on potential targets would be appreciated, my "Go to system" is my left hand.. Thank you, John M

The H-beta filter will work on the horse head and the California nebula ngc1499 but that is about it for the h-beta. The O-III or UHC are a much better choice for viewing faint nebula. They cover a wide range of objects.
Try any of the messier nebulas m1 the crab, m27 the dumbell, m57 the ring, m76 the little dumbell, m97 the owl, ngc40, ngc6543 the cats eye, ngc7662 the blue snowball, ngc6960 the viel nebula, ngc2022 (one of my favorite), ngc2392 the eskimo nebula, ngc3242 the ghost of jupiter, ngc2438 inisde of m46 (kill two birds with one view).

Those should keep you busy for a while.
I wouldn't use very high power on most of these. Maybe 75 to 120. Except ngc2022 pull an Emeril on it "kick it up a notch".

Keep in touch let me know if I can help.
