Quick DeliveryWe are off to the US this weekend and will be there for the total eclipse, which we only found out on short notice. Was great to be able to order these glasses and have them so quickly! We'll only be trying them on the 21st August from South Carolina so can't comment yet, but I am sure they will be fineMichelle

Prima Sonnenschutzbrillen als SammelbestellungPrima Produkt, ideal zur Beobachtung der Sonne mit dem unbewaffneten Auge. Habe im Betrieb angesichts der bevorstehenden Sonnenfinsternis (20.3.2015) herumgefragt und dann eine Sammelbestellung gemacht. Lieferung erfolgte innerhalb weniger Tage, alles klappte einwandfrei (incl. der Vorkassenbezahlung). Sehr erfreulich: das Ganze war versandkostenfrei :-)Klaus Wegener

Will it fit a Richey Chretien SCT 8ins?Is Answered? Yes (1 answer)
Answer rated: 0Unfortunately we cannot definitely answer your question without knowing more about your telescope, for example brand,. backfocus and rear thread. Please try to find this out by contacting the manufacturer of your telescope, and contact a Baader Planetarium dealer/distributor in your countryAnswer by: Baader Web Team (Admin) on Apr 15, 2024 8:51:00 AMRated: 1
I have a Sony 10 MkiV
I want to take pictures safely of the sun.
The camera has a screw thread for a lenss
Please advise the best productIs Answered? Yes (1 answer)
Answer rated: 0We are very sorry we have no filters with threads for mounting on lenses of compact cameras. You can make your own filter with an sheet of AstroSolar 20x30cm https://www.baader-planetarium.com/en/solar/whitelight/astrosolar-safety-film-od-5.0-(20x29-100x50-117x117-cm).html or you can check if one of our ASTF or ASBF filters https://www.baader-planetarium.com/en/solar/whitelight.html
fits for your needs. For this, you need to measure the diameter of your cameras front lens and compare with the values in this table https://www.baader-planetarium.com/en/downloads/dl/file/id/299/product/2986/baader_solar_filters_clamping_range.pdfAnswer by: Baader Web Team (Admin) on Apr 12, 2024 3:20:00 PMRated: 3
Hello, I've buyed the #2956269 M68i x 0,75-ClickLock (Hexafoc: Bresser / Explore Scientific, Omegon) for my Ultra light dob 12' 2nd gen Explorer Scientific but It doesnt fix! Which one should I ask for?Is Answered? Yes (1 answer)
Answer rated: -2Unfortunately we have no information about the threads on your telescope focuser. Therefore we cannot answer your question. Please contact the manufacturer he should be able to tell you the thread, then you can choose the right clamp from the listAnswer by: Baader Web Team (Admin) on Apr 11, 2024 9:26:00 AMRated: 1
At what % transmittence is the 10nm HBW measured?Is Answered? Yes (1 answer)
Answer rated: 0At half bandwith. The 10 nm O III filters were done with older coating technology, hence peak transmission was around 85% - which might be the core of your question. The newer 9 nm O III filters are three cavity filters with steeper slopes, higher peak transmission and better off band blocking – it is another coating technology alltogether.

Is it possible to obtain the D-ERF energy protection filter for SolarSpectrum H-alpha filters more cheaply from other sources?Is Answered? Yes (1 answer)
Answer rated: 37We must point out that purchasing the ERF from another source can lead to a repair becoming chargeable in the event of a defect during the warranty and guarantee period.
A normal ERF is cheaper to buy. But it does not have the same specifications as our DERF: Simple ERF filters are made of solid-colored red glass (Schott RG 610 or RG 630). This glass is a long-pass filter; it allows all energy to pass through from approx. 570 nm, including the full thermal radiation (NIR) above 630 nm.
The heat at the focal point is three times higher with this type of "protective glass" than with our dielectrically blocked D-ERF filter. As a result, the immersion oil in the stack of block glasses, polarizers and etalon in the H-alpha filter literally is getting boiled. An H-alpha filter that is permanently overheated in this way ages very quickly. We would not be able to maintain our 5-year warranty under any circumstances.
Incidentally, the colored glass from which these simple ERFs are made is very "soft" and chemically unstable (= prone to weathering). The soft molten glass tends to form streaks. When we were still working with this glass, we had to double-pass test each piece on the optical bench and had a high reject rate. This means that simpler ERF filters age due to the oxygen in the air if they are not coated, the surface becomes "rough" after a few years and the image contrast collapses.
The problem with the glass quality of the RG 610 remains even if a UV/IR-reducing coating is vapor-deposited. We have already done this many years ago as C-ERF filter (= Cool ERF), but after long-term experience we abandoned it again and the lesson learned was the development of the D-ERF (Dielectric ERF). Above all, the soft glass often warped during coating, which led to even more rejects.
There are manufacturers who offer such ERF or C-ERF filters but do not test every lens as thoroughly as we did on the optical bench. This explains the cheap offers of C-ERF and ERF filters on the market - for which the customer ultimately pays much more than if he had purchased a high-quality DERF, with significantly reduced image quality and reduced service life of the Halpha filter.
Our D-ERF filters are made of highly homogeneous, streak-free, finely polished BK-7 glass. They are painstakingly coated with a dielectric coating system that is resistant to ageing and precisely matched to the Solar Spectrum filters.
The Solar Spectrum filter only shows its most important advantages (ageing resistance, sharpness and contrast) with our dielectric „D“-ERF coating system were we have full control over the coating process and can verify it´s effectivity. Only then can we guarantee for the 5 years of ageing resistance for the Solar Spectrum H-alpha etalon-stack. Especially with a research grade filter, usage of a "normal" ERF is tantamount to "degrading" the filter. Every chain is only as strong as its weakest link.
