Baader AstroSolar Visual Solar Filter Film (ND 5) - A4 Sheet 20x29cm (7.9x11.4) # 2459281

Seeing that there are few recent reviews, I wanted to say that the Baader solar film is excellent. Yes it is expensive, however compared to an commercial off axis solar filter which would cost 145$ for my scope, I couldn't be happier. This film is easy to cut, easy to make a housing for the scope, plus doing off Axis I have extra for binoculars or another scope.One other thing, others mentioned that the film shipped in a flimsy package. When I received mine it was in a large cardboard box and was well protected. No creases or bends.In all, you cannot go wrong with this solar film and the clarity of the sun is stunning!

Worked great over my camera lens for partial solar.

This protected all my optics during the solar eclipse, camera, sighting scope, telescope, binoculars and my eyes. Pictures had white light and astounding contrast. I prefer the white light over the orange found in other kits. Baader states not to worry about slight ripples as you make you own filters, they were right, no image degradation what so ever, check out the sunspots!. Take your time constructing your filters, plenty youtube videos. I made several from this pack, cover them with soft kleenex, you're good for the next sunny day.

This is the correct film for making filters to look directly at the sun. The film comes with instructions to make a filter. I made one large filter for my spotting scope and one for my binoculars.

I bought a bunch of stuff for the eclipse. This did not end up getting used on any of MY equipment. A friend let me use his thicker version on my binoculars, secured with electrical tape (we weren't really super prepared). This got used on other people's cameras however. Again we weren't prepared and were setting up a little last minute with electrical tape, first aid shears, and stray cardboard. After other iffy attempts someone figured out you could take a piece of this and screw it down under another filter if your camera lens had one and it worked reasonably well. So I guess, if you're using this prepare early with the right tools in case you're not able to figure out how to wing it like we did. In terms of sun blocking for safety and good photography, that part was pretty much flawless. If you like things simple like me you might end up using another option like I did. Glad I had it though, as it did allow my friends to photograph and I'm not sure they otherwise would have.

Just a sheet of safe solar viewing film that you can muse to make your own custom solar filters.

Needed it to make solar filter for binoculars. Worked as expected.

This stuff may be the best stuff ever for photography, but I won't be using it.Edit: I need to recant that because as much as I hate working with this stuff, the images are just spectacular.First of all, it's impossibly thin: the included docs say that it's 0.01mm thick. It feel like shiny gossamer tissue paper and it's SUPER easy to damage. I've worked a lot with the other brand's film and never tore it and never had a pin-hole. The first time installing this stuff and I got a pin-hole. That's half of an almost $50 sheet ruined since I'm making filters for a very large lens (500mm f/4).Second, while not well advertised, this stuff is NOT ISO 12312-2 and is therefore not safe for use in glasses or viewers - use only with cameras and in theory telescopes (which is a bit weird). That's shown in the docs, but damn that should really be front and center and this show not be advertised as "visual solar filter film" like it is. In a nutshell that means that this film is probably allowing harmful UV and IR light through which will damage your eyes. It then goes on to state that it's OK to use on a telescope for viewing, but I'll pass, thanks. To be fair there is a warning about this on the very bottom of the ad copy, but it should be higher up IMO.The reason for it producing sharper images is likely due to it being thinner and not meeting ISO specs. Sounds great but cutting this stuff and moving it around is a huge pain because it's just so thin. It wrinkles like crazy (which is not supposed to matter) and it's so light that if you breathe on it it flies away. I included pics of my my super-bright LED flashlight as seen through both the other brands orange image film and you can see that the image is clearer - and it's clearer because it lets more light through.Edit: I need to add that the difference in exposure is dramatic. A shot that would be 1/200th at f/5.6 using the other material is 1/2000th at f/5.6 with this stuff. That's a big deal for a big lens like the one I'm using.If you make a filter out of this stuff make sure to check it for pin-holes *every* time you put it on. It's crazy how easy it is to damage this stuff, and the bigger the filter, the harder it is to keep from getting damaged. Note also that the stuff is so thin that when I push the filter on the lens the air pressure causes it to bubble up, so make sure your filters are securely made!

fragil pero bueno

Parfait pour observer le soleil. Alors oui c'est fragile, mais je m'attendais à pire. donc il y a qd meme une bonne marge pour le manipuler. A noter qu'il faut qd même le stabiliser et ne pas le laisser trop onduler sinon le rendu s'en ressent. Le soleil donne un rendu blanc/bleu. La photo est possible, et le rendu est bon mais s'il faut savoir régler son appareil. mais je crois qu'il existe d'autres filtres solaire spécialement adapté à la photo.Emballage top.

Bought for DIY lens filters for solar photography at 640mm (FF). Although flimsy material (naturally), relatively easy to cut and trim when held between its protective sheets.Advised against pulling taut, and wrinkles are of no consequence to light transmission (but don't tear/crease.)Very happy, and A4 sheet should last a long time.

Buena calidad y bien detalladas las instrucciones de uso y montaje, fácil de hacer si no eres un pato con las pequeñas manualidades.. a tener en cuenta, la lamina es muy delicada así que trátala con mucho cuidado si no quieres que se hagan marcas.Aquí mi resultado de filtro para cámara , lo hice con un trozo de cartón que tenía por casa, pegamento y celo para asegurarlo más..

Ci ho messo un po' per scrivere questa recensione. Prima ho dovuto preparare un adattatore per applicare il filtro all'obiettivo della macchina fotografica. E ho dovuto lavorare un po' perché ero indeciso su come farlo. Ieri, finalmente, l'ho provato. Ok, la prova non è andata a buon fine. Il cielo era velato, era già un orario in cui il sole stava calando, e ho avuto qualche difficoltà a inquadrare l'astro. Devo fare un po' di pratica. Non sono riuscito a fare una foto decente... ma è colpa mia, non dell'apparecchio fotografico, né del filtro. Difatti alla fine mi son preso il filtro, l'ho puntato direttamente verso il Sole, e ci ho guardato dentro a occhio nudo. L'immagine appare nitida, ben definita, e non da fastidio, e neppure imbarbaglia. Per cui funziona.Sono soddisfatto.Riguardo al Filtro in sé, è un foglio sottilissimo e delicatissimo. Va maneggiato con cura, e applicato al supporto che vi costruirete con una certa delicatezza. Consiglio di pensare a delle coperture per proteggere la pellicola quando non la usate, così che non si fori, o danneggi. Sarebbe un bel problema sia per la vostra retina, sia per il sensore della vostra macchina fotografica.Il foglio A4 è più che sufficiente per realizzare un filtro per la macchina fotografica e un occhialetto per la visione 'a occhio nudo'. Oppure per creare due filtri per un binocolo.
