Re: Baader ND3.8 1m roll expression of interest
I've just sent a 'Contact us' request.
We have 39 astronomers with a pledge for 51 rolls and 2 provisional. I couldn't find any responses on the German site.
I'll post the response from Baader here when I receive it.

Re: Baader ND3.8 1m roll expression of interest
I can be interested depending on the price. I have a crazy project in mind. I spoke a couple of weeks ago with Bob Luffel at Alpine and he told me Baader may consider a new run early next year in view of the upcoming 2024 solar eclipse. I have down to contact him next January.

Re: Baader ND3.8 1m roll expression of interest
Hello Alexandra,
On Astrosurf French forrum, we are up to 39 rolls.
I don't see any response on the German forum, but I don't read german. I'll ask Alex to make sure.
Cloudy Night never answered my message asking their authorization to pass the info.

Re: Baader ND3.8 1m roll expression of interest
Thanks a lot Alexandra for your efforts!
Therefore, if there is still an opportunity, please add me in the list for one roll.
After my first solar scope last year, I recently saw my second dream of two decades coming true. I received my C14 Edge! :-) :-) :-)
I am really excited as you can imagine. I would like to be able to use it for WL in the rare cases of perfect seeing...
Christian's solar photos are so inspiring that I would love to try.
Hopefully Baader will respond positively at the end.
Thanks once more,
Alexandros
I have missed your recent post on astrosolar when you sent it out and today Christian kindly let me know about these efforts by you and him.

Re: Baader ND3.8 1m roll expression of interest
That's fine Alexandros. It is now two weeks since I wrote to them and not even a reply saying anything at all. There are more than 40 astronomers waiting patiently for a reply
I am very disappointed to say the least. I think it is more polite to say, sorry but no, than absolutely ignoring me.
Does anyone have an email address for Mr/Ms Baader?

Re: Baader ND3.8 1m roll expression of interest - Update
Finally an update which I will share in full for you. So we need to be patient and hopefully it is coming soon Thank you Baader
Dear Ms Hart,
please take our excuse for the belated reply. As most everyone we are overwhelmed by supply problems and exploding prices for raw materials. In fact we are struggling to keep our Baader products available without too many gaps in certain product families - Astrosolar film being one of them.
As mentioned to Mr Viladrich, we do thank you and the group for contacting us on this matter of large size Photosolar-Film in OD 3.8.
Unfortunately at this time we are unable to fill such a request. It may take us until end of this year to enable us supply such large sizes in OD 3.8 again. We dearly hope the supply issues that we face will improve within coming months. We are working on a method to increase safety while offering this OD.
There are numerous stages in the production process that need to be observed most carefully, in order to maintain optical quality and freedom from astigmatism. This film just looks so simple, but in fact it is a severe task to produce it in true optical quality. We will gladly inform everyone on our website as soon as we are successful.
We will definitely not forget this inquiry and hope by end of this year latest, to being able to serve you and the group,
Please bear with us and be thanked again for your interest.
Best regards,
Thomas Baader

Re: Baader ND3.8 1m roll expression of interest - Update
Hi,
I would be interested in 2 rolls.
How much would 1 roll cost approximately.
Woukd it be ordered from Baader UK, as Baader in Germany charge a lot in postage.
Thanks.
Magnus

Re: Baader ND3.8 1m roll expression of interest - Update
One can use ND 5, but it becomes suboptimal when you push the setup towards optimal sampling and contrast. E.g., at f/16 and with Solar Continuum (which is quite narrow at 8 nm), ND 3.8 led to about 7 ms exposure (at zero gain, with histogram at 80-90%) with the ICX445 sensor (newer ones might be better by a few 10s of %, but that's it). ND 5 would require about 16x longer, which in less-than-perfect seeing would be unworkable (on the other hand, on new sensors you can increase gain a lot and still not get too much noise).
If all you can get at the moment is ND 5, by all means give it a go (and don't use very narrow filters; e.g., use a "visual" green filter instead of the Solar Continuum).

I'm not a v good imager, but in case its of interest DavidP here - viewtopic.php?t=36658 - are some images I took 2 days ago w ND5 film. I used an Astronomik 642nm long-pass filter (ie a broad band pass as GreatAttractor also says).

Re: Baader ND3.8 1m roll expression of interest - Update
Hi Alexandra!
I am interested in one of these sheets of film for my 12" Meade. Is Baader going to put them on sale to the general public or just for this group? Because I live in Argentina and I don't know how they would be shipped.
Another question, are they only going to sell the 100x50 cm sheets or also the filters already mounted on a frame?
Thank you very much!

Re: Baader ND3.8 1m roll expression of interest - Update
Dear Shadowchaser,
I would presume that it would be on sale for the general public, you would need to buy direct from Baader. We got this expression of interest going to show Baader that if they produced a run they would have enough people who would buy it. It was an incentive. So order through your normal channels. Usually you have to buy a filter with a ND5 in, then buy the film and replace the ND5 with the ND3.8. I think they sell the filters cells with ND5 fitted only.

Hi Alexandra and all,
Many thanks for all your efforts on this and the good news/promise from Baader that they will produce it again until the end of the year.
I suppose there are no updates since, you communications with Baader. Would it be good to ask them again on behalf of the many of us who are interested and see if they will able to have filters available soon?
Best wishes,
Alexandros

Hi All,
I wrote to Baader asking for an update for you all, I wrote on both the 12th October and again on the 7th November and have not had even one reply. I don't think this silence is very promising I had hoped that we would have some encouraging news by now.
Just a reply would be helpful

Hi Alexandra,
I hope you are well.
You had started this great effort quite some time ago. Did you ever had more news from Mr Baader?
It's been a long time since they promised to "serve our group", but unless I missed something, they did not proceed to production.
Would it be possible to contact them once more on behalf of all of us and ask if they have something scheduled during the year?
Best wishes,
Alexandros

Re: Baader ND3.8 1m roll expression of interest - Update
Hi Alexandros,
Despite numerous emails to Baader they never reply to me. I got annoyed and have moved my custom to other brands. It still does not help the fact that I and others need this ND3.8 in bigger sheets than pitiful A4.

-.- .. weird, they state that they are scared of legal consequences from misuse. On the other hand they still sell the 200mm sheets.. : D
Sad, my C11 could also use some of this film.

Re: Baader ND3.8 1m roll expression of interest - Update
It's very disappointing that the film alone is still not available.
However, I've noticed these (both available on order):
1) Baader Solar Filter for telescopes from D= 12" - custom-made 326.89 EUR ("Will be ordered for you")
Description:
I hope it's not the new normal: ND 3.8 >20 cm only available bundled with very expensive cells.
update: Baader also show the BDSF filter cell on their website: link

Description:
2) Filtr słoneczny Baader BDSF 280mm OD=3.8 999 zł (~217 EUR)You can decide if you want the solar filter with photographic or visual foil when ordering. The photographic foil has 16x more transmission and is intended for stargazers who want to photograph the sun primarily.

Thanks for the info Filip
But having to buy a new cell each time would be highly irritating!

Re: Baader ND3.8 1m roll expression of interest - Update
I remember that around 2012 OPT had a big roll of ND 3.8 (a few meters x 30 cm or so) for something like $100. I almost bought it, but... "It would be nice to have a lifetime supply, but I'll be always able to buy smaller pieces as I need them, right?"
