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

It seems to be best choice.

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 ?

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'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.

Thanks, i'll buy it and probably go for an Herschel over an astrosolar film. I suppose it would be better.

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.

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.

So Altair would be a compromise ?

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 ?

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.

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 fo...

I have the Lunt 1.25 that I use with my Orion ED80T with no issues. What scope are you using yours with? 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 ...

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.

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).

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.

Oups, i tought both were uv/ir blockers with better filtering for KG3.
So i'm wrong, what's the reality please ?

But front erf would be better to protect both etalon and refractor or due to diameter no matter ?
And between KG3 and Astronomik which one to choose ?
Thanks for advices.

I'm on Ha but it could be usefull to have a wider filter with L1.
I was looking to Baader 20nm or perhaps Optlong Ha but rather use Astronomik.

No matter for short sessions but can i try for a longer time ?
You use L1 for any reason ? L3 seems to be the more restrictive.

Hi,

Have you got some experiences with a quark and an astronomik L3 2" front mounted on diagonal ?
Can it works well with 4" refractor for 30-60 min sessions ?
And no matter if using a Baader Bbhs diagonal or Baader solar diagonal would be better ?

I tought i'll use Ft focuser but finally i rather use my takahashi focuser, probably because it have dual speed.

Here somes photos. To resume it's a mod with takahashi, lunt 50 directly screwed on takahashi fc-100-df. Initially i have a Baader diagonal with clicklock for Takahashi, and when i unscrew just clicklock i have the right fitting for lunt (between draw tube and clicklock there's a Baader ring). Today...

I'm in holidays but photos next round for sure !

Finally back, i tried this mod and found it easier than pst. I really like it and i impressed with views in my taka. I can achieve a very pleasing 3D effect, i didn't think it would be possible with my material. I changed lunt focuser for FT solution but i need to use the focuser of my refractor and...
