Choosing herschel

Post by EboO »

Hi,

Please which herschel wedge would you choose in 2" ?
I already have a 1,25" Lunt but it's hard to use due to a too short focuser travel...

Thanks.

I can't believe no one answered this, so i hope you will get your answer.

I posted or commented here only to say that recently i asked people on Facebook about Lunt Wedge 1.25" because i don't want to go with Baader Herschel which is so expensive as a wedge really, but sounds 1.25" version of Lunt isn't recommended, you mentioned about short focus travel, another one mentioned about heat resistance performance compared to 2", so i think i should just go directly to 2" version and never look back, but Baader one is the best out there, but pricey, so i either wait to afford it, or just buy any other 2" Herschel that is a bit cheaper than Baader one.

Hi,

Thanks for your answer. I too think Baader 2" is the best but a bit pricey.
For the moment i play with my quark and lunt 50, i looking for a good classified (Baader or Lunt).

I want to complete the three known solar filters so WL is one of them, and all said that it is the best done with Herschel Wedge, i already have the Quark since last year and CaK since this year but i didn't play with any yet for some reasons, i will finish scopes choices then i will use them all.

You're right and CaK seems very interesting, so Herschel is necessary (or a quark but not the same price).
I tried pst, lunt 50, lunt 50 mod and quark and for the moment the easier for me is the quark.

I use a takahashi fc-100-df, the focus travel is a problem with 1,25".

@TareqPhoto i start quark before installing my setup and it's easy to find the sun before mounting quark.
And because i'm a fan of big magnification for sun quark is ideal.

Ok, i will give it a try one day and see, i only did with Antlia Herschel Wedge and CaK filter and it was easy to do really.

I have an other project for white light, with a 10x bino.
Initially i wanted to buy Thousand Oaks threaded filters but i live in Europe and shipping costs are very high. I found an alternative with Astrozap, but is it as good as TO ?
Or Baader astrosolar is the best solution ? I have a preference for glass over film but perhaps am i wrong.
If some members have advices...

If i can remember well, the wedge is better than solar film, this is one thing, second thing is, the film is better than glass, almost all mentioned that, so your first choice is the herschel wedge then the second one is film, now which film....?

If i have to put them in order then i will put Baader as first, then Astrozap second, Thousands Oaks is very nice one but i see more solar film used by users from Baader and Astrozap than Thousands Oaks.

Ok, so the best solution would be baader astrosolar and it's not really pricey so i can give a try, and if i’m disappointed i go again on herschel.

Hi,

What would be the most interesting with solar film : polarized or continuum filter ?
If continuum filter have you got some feedback with the altair ?

Best would be Continuum filter for seeing granulation detail. I've only ever used the Baader version and this is great. However, I recently purchased the Altair G-Band filter and this is like a cross between Continuum and Calcium, the granulation is very sharp and obvious and you can see faculae well into the middle of the disc. However, the spot penumbra and umbra is much darker.

You're right, during this time i read some articles about each one and the continuum would be the best choice for me. But it seems to be marginal in quality result for visual, better for photo and altair seems to be slightly better.
Users' experiences remain the best way in my opinion.

Here is a thread to show you images of the differences. There is no brand difference, it is wavelength that matters and give different visual effects. A polarising filter is a completely different thing again and will reduce glare if you are finding visual too bright.

G band is really interesting, is it for both visual and photo or just photo like CaK ?
Perhaps i need to try VA such a filter.

The 1.25" just screws on the eyepiece or camera nose, there is no need for a 2"

I'm near to buy a lacerta herschel wedge with nd3 filter but i wonder if i also need a polarizing filter in addition with a G band ?
I found that for visual use it needs a nd5 filter.

Nice to know, thanks. It will works like nd3 with continuum or being brighter ?
Finally i tried astrosolar film this week-end and i rather go with an herschel wedge, i feel it more secured.

I continue to collect informations about G band and i found one that makes me a doubt : seeing in my observation place is average to good, so is it a good choice or must go for a continuum ?
I use a takahashi fc-100 doublet, so i guess it's better corrected in green than blue ?

Hi Oleg,

I've not tried it with either scope yet to be honest, onluy my 80/600 stopped down to 60/600. I suspect I will use it with the 127/1200 though as I can rarely use 152mm aperture with Ha, so, being able to use it at 430nm will be even less opportunities in a year will be proportionally less. A slower focal ratio scope will always perform better at the shorter wavelengths though.

Is the best way for using G band is stopping down the refractor ? To avoid as possible the turbulence effects ?

Yes. Lesser quality refractors will still have some spherical aberation at 430nm, however importantly it also helps with oprtimal sampling when imaging.

The Baader wedge is quite popular. I think they got two versions, a visual wedge and an imaging wedge. I may be wrong though. Not sure.

The visual comes with the 2" Continuum filter and ND3 filter. Both are used in combination. Results are excellent.

The photographic version also includes 2" ND 0.6, 0.9 and 1.8 filters.
I have never used these filters for the two reasons:
1. I like to do both visual and photographic. Changing the ND filter back and forth is a bit of effort, and for safety reasons, I prefer to keep the ND3 installed.
2. The ND3 + Continuum filter combination is plenty bright enough for photography IMHO.

I see they have a MkII version now as well.
https://www.teleskop-express.de/shop/pr ... isual.html
The benefits are a little unclear, given the significant price hike.
The original version can still be purchased:

So finally I have a Lacerta herschel wedge.
ND3 is screwed on wedge but for other filters i'm a bit lost.
I have an OIII, a polarising filter (both Baader, can be screwed together) and a KG3.
Can I screw the KG3 after the ND3 ? Otherwise I can screw polarising filter after ND3 and KG3 on eyepiece but I can't rotate polarising filter...

The visual comes with the 2" Continuum filter and ND3 filter. Both are used in combination. Results are excellent.

The photographic version also includes 2" ND 0.6, 0.9 and 1.8 filters.
I have never used these filters for the two reasons:
1. I like to do both visual and photographic. Changing the ND filter back and forth is a bit of effort, and for safety reasons, I prefer to keep the ND3 installed.
2. The ND3 + Continuum filter combination is plenty bright enough for photography IMHO.

I see they have a MkII version now as well.

The benefits are a little unclear, given the significant price hike.
The original version can still be purchased:

I keep asking myself about the two versions, is the difference only by filters or the wedge itself, if it is only the filters then i will buy the cheaper version as i have something, or i can buy filters later when needed, but if the difference is in the Herschel Wedge itself then i want to know what is that difference if it affect using it for visual or for photographic purpose, i am mainly a photographer, but i don't mind having for visual when needed, and i wanted to go with Baader Wedge rather than other brands, sounds Baader is always the top recommended vote.

Only the extra filters. Exact same wedge.
