Heads up - H beta filter offer

[Knighty2112]

Heads up if anyone fancies an Explore Scientific1.25" H-Beta filter. Telescope House have an offer on them, so you can save some money on one.

Hehe! I did! That's how I noticed the Telescope House offer after googling it to see how much the retail price was!

Good luck. I bought his Lumicon Hb this time last year! I guess that the ES one was also unsuccessful in Rvealling the elusive HH.

Hi Paul, in the right circumstances, the lumicon H-beta will do a good job at revealing the HH, good luck if this is on your agenda.

Those are the key words. The reason I've let the H-Beta filter go (again !) is because I just don't think my observing site is dark enough to take advantage of it's capabilities.

If and when I start observing from a darker site, I'll probably get another one. Meanwhile, someone else can have a go

If you are presented with an opportunity John to observe for the Horse Head once more, perhaps there will be a member in your astro society who would lend you a H-beta filter and particularly if members organise meets at a dark(er) sky location.

When you do see the Horse Head, it feels as though you have been given a key, it becomes easier next time. It would subsequently be possible under very good transparency to observe with averted vision with conviction from your good quality sky at home.

Sorry you sold the H.Beta filter John - I hope Gus is more successful. I still want to buy another H.Beta filter to go in my Apollo 15x70 binos to get a better view of the California Neb.

Thats a good plan. Originally I thought that having access to my society observatory would give me darker skies but it turns out that the skies in my back garden are better than at the observatory !

We are looking for a darker site though so I hope to get involved with testing prospective locations to see how dark the skies are

To be fair to the ES H-Beta filter (Gus will be pleased to hear this) it did show me more than the Lumicon H-Beta that I had before did and on a wider range of objects as well.

There are many people that observe under far worse skies than mine so I can live with them not being quite dark enough for one of the toughest deep sky challenges

Glad that I bought that Lumicon Hb off you now..... Still no horsey. ???

Only joking. The Lumicon works fine but seems to need a bigger scope to make it fly (kills too much in my 10" but shows things nicely in my 16" - just not the HH).

I look forwards to reading Gus' thoughts.

I found the Lumicon filter to show more details overall, it's a 2" though to be fair.

Was that with your 22" Mert ?

[mert]

It was in my dads 16" and my 22". Haven't had a chance to compare them properly side by side in both scopes. I did a switch in my 22" and I felt the Lumicon edged it, but to be fair it's a 2" filter. The HH is my nemesis, I've seen it once in the 16" and on a good night the 22" can always show it, not with the full moon though  at £39 the ES is a very good buy compared to the Lumicon.,
