Hi all,
My first posting on CN regarding my observing sessions. My friend Andreas and I were out January 1st and had great views of the HH. The transparency was about 5/5 which was incredible. I could easily make it out with his Televue 55 plossl, H beta filter, and my 25" scope. It was upside down with the nose pointing to the right. To me the 55 plossl was a better view than with my 35 Panoptic which is currently my lowest power EP. I did not look but Andreas said he could pick it out in his Celestron 11" CPC with the 55 plossl and H beta filter. To be honest most of my views of HH before last night were the "I think I sorta kinda see it" views. Last night there was no doubt. I surprised myself with my own comments. I said stuff I usually hear other folks saying when they look through my 25".

I was with David that night. It was awesome to see it as sharply defined as we did. In my 11" the nebulosity was bright and Horsehead was a distinctive black shape in the nebulosity. In David's 25" the view was stunning. The shape was extremely well defined against the very bright nebulosity. Using the H-beta we also got a good view of the California Nebula as well.

Congratulations David. It is amazing what aperture can do isn't it? When an object that is usually described as marginal looks like the profile of a Chess Piece. I think now your scope has paid for itself hasn't it?
Now go out there and dig deeper. That was an easy one.

Bill,
Yeah, I guess I should have titled my piece, "I finally bought my view of the Horsehead! 
For me the telescope is definately worth the price. No more feint fuzzies...
One perspective to consider is how much money folks spend on their hobbies too, especially the yachting and fishing crowd around the Chesapeake Bay area.

Yeah, but in the case of the Horsehead, the key is the H-Beta filter, not aperture.
Even more dramatically true of the California Nebula, which is a challenge through any scope unfiltered, and is visible naked-eye with H-Beta filters.

Very True... My buddy sees HH with his 11" SCT using the H-beta filter. He also told me that the HH has been seen with 15x80 binos outfitted with the H-beta filter. I have to admit though, it was larger than expected in my scope. Like Bill mentioned previously, it did look like a chess piece.

Usually when I get together with David in addition to my 11" sct I bring my 8" lightbridge. With the 55mm Plossl I can see over 4 degrees of the sky. I wish I had it that night for viewing the California.
Your right that the key to both the California and the Horsehead is an H-beta. With the HH though aperature does help quite a bit to. I have seen part of the HH with a 4.5". In an 8" I could see much more of it. With my 11" it was well defined. With David's the 25" it was amazing with a wonderful outline.

Well, it is up to 20 (and more will undoubtedly be added to the list)
USEFUL TARGETS FOR THE H-BETA FILTER
While the H-Beta is probably one of the less-used nebula filters, the commonly expressed idea that it works only on a handful of objects is not true. Here is a list of the more prominent objects that the H-Beta may be at least somewhat useful on. Some may require larger apertures, but a few have been seen from a dark sky site by just holding the filter up to the unaided eye and looking at the sky. Some of these will also be helped by a narrow-band filter like the Lumicon UHC.
1. IC 434 (HORSEHEAD NEBULA)
2. NGC 1499 (CALIFORNIA NEBULA, naked eye and RFT)
3. M43 (part of the Great Orion Nebula)
4. IC 5146 (COCOON NEBULA in Cygnus)
5. M20 (TRIFID NEBULA, main section)
6. NGC 2327 (diffuse nebula in Monoceros)
7. IC 405 (the FLAMING STAR NEBULA in Auriga)
8. IC 417 (diffuse Nebula in Auriga)
9. IC 1283 (diffuse Nebula in Sagittarius)
10. IC 1318 GAMMA CYGNI NEBULA (diffuse nebula in Cygnus)
11. IC 2177: (Diffuse Nebula, Monoceros)
12. IC 5076 (diffuse nebula, Cygnus)
13. PK64+5.1 "CAMPBELL'S HYDROGEN STAR" Cygnus (PNG 64.7+5.0)
14. Sh2-235 (diffuse nebula in Auriga).
15. Sh2-276 "BARNARD'S LOOP" (diffuse nebula in Orion, naked eye)
16. IC 2162 (diffuse nebula in northern Orion)
17 Sh2-254 (diffuse nebula in northern Orion near IC 2162)
18. Sh2-256-7 (diffuse nebula in northern Orion near IC 2162)
19. vdB93 (Gum-1) (diffuse nebula in Monoceros near IC 2177)
20. Lambda Orionis nebular complex (very large, naked-eye)
In addition, a number of the brighter nebulae like NGC 7000 or M42 will respond to H-Beta use for revealing certain specific detail, although other filters may provide a somewhat better view overall.
Clear skies to you.

Yes, I used my Astronomik H-Beta on M-42 and the Eta Carina nebula the other week in my 8" on not the darkest of skies, and I was amazed at how much was visible - I was expecting to see nothing. Of course, nothing is exactly what I saw of the Horsehead :-{

I've seen it with my 10-inch from a very dark area using a H-beta filter. Through Tatarjj's 18-inch it was obvious without a filter at all, so it should be no surprise that you spotted it with a 25-inch. In a 10-inch the shape of the Horsehead is pretty vague, but very obvious in a big telescope. Congratulations on seeing the Horsehead, it's a sort of Mt. Everest of amateur astronomy.

USEFUL TARGETS FOR THE H-BETA FILTER
....
Quickly checking my observing database, I have a few more suggestions --
Ced 90 = Gum 3. This low-excitation nebula is located at the extreme southern tip of the 2.5° emission strip IC 2177 (on the list). David already included vdB 93 = Gum 1 which resides at the north end of this huge filament and responds well to an H-beta filter. But strangely, I didn't find an H-beta filter helped on NGC 2327 (also part of the same complex). I'll have to try that one again.
IC 418. This is a low-excitation planetary and using a H-beta filter in my 18-inch the halo brightens and the central star fades, leaving a more noticeable disc.
Simeis 57 = Propeller Nebula. This faint emission nebula is about 3° north of the Gamma Cygni complex (IC 1318).
There are other objects which the H-beta enhances, though possibly not the best, such as NGC 40. But some of the contrast enhancement is really aperture dependent and the larger the scope, the more objects you can add to this growing list!

Freddy,
You are right. Even in the 25" many objects are feint fuzzies. Thanks for putting it in the correct perspective.

Hi all,
Thanks for all the input. I am enjoying all the replies and really did not expect many. This is the first I have heard of the H-beta list from Dave Knisely. I really appreciate all the inputs for new H-beta objects. In the future I post any of the items I am able to see.
