Latest information on the solar eclipse on 12 August 2026
🌒 The solar eclipse on 12 August 2026 – what Germany can expect
On the evening of 12 August 2026, an extraordinary celestial event is set to take place: a total solar eclipse will pass over parts of Europe – though not over Germany. Here in Germany, we will experience an impressive partial eclipse, which will nonetheless provide a rare and spectacular spectacle.
🔭 What can you see in Germany?
Germany lies entirely in the penumbra of the Moon. As a result, the Sun is not completely obscured, but is clearly nibbled away at. The extent of the eclipse varies from region to region:
- Berlin: approx. 85% coverage
- Bremen: approx. 86%
- Düsseldorf / North Rhine-Westphalia: approx. 88%
- Frankfurt am Main: approx. 88%
This makes Germany one of the regions with the highest coverage outside the totality zone.
🕒 Times of darkness in Germany
The eclipse will take place in the early evening – perfect for viewing, as the sun is still relatively high in the sky but the light is already softening.
- Start of the partial phase: approx. 19:11–19:20 CEST
- End of the partial phase: approx. 20:48–21:03 CEST

The Altair Dichroic Solar Energy Rejection Filter or D-ERF protects your telescope and solar imaging equipment from excessive heat build-up when solar imaging or observing with your Daystar Hydrogen Alpha Quark, or other Hydrogen Alpha Etalon filters.
756.00 €
Estimated delivery time : 1-2 weeks (valid for new orders)
The Altair Dichroic Solar Energy Rejection Filter or D-ERF protects your telescope and solar imaging equipment from excessive heat build-up when solar imaging or observing with your Daystar Hydrogen Alpha Quark, or other Hydrogen Alpha Etalon filters. Now you can save money by combining Hydrogen Alpha, Calcium K-Line and Calcium H-Line in one TRIBAND pre-filter.
Product Features:
- Reduces approx. 98% of heat reaching the optics to keep Etalon from drifting off-band and protect your equipment.
- 30nm FHWM Bandpass at H-alpha (H) wavelength of 656.28 nm (Full Width Half Minimum) Transmission: ~95.5%
- 40nm FHWM Bandpass with CWL at 395nm covering Calcium H-Line and Calcium K-Line wavelengths. Transmission: ~90.5%
- UVIR blocking OD3 0.1% @400-1100nm blocking over 98% of heat to your 3rd party Etalon at eyepiece or camera end, E.g. Daystar Quark). Please note it's your responsibility to use a proper commercial Etalon with this product, and to follow the manufacturer's instructions.
- Visible light blocking: OD4 0.01% @400-700nm to reduce reflection effects and over 98% of heat.
- Diameter 120mm Thickness 12.0mm (required to achieve surface precision)
- Multilayer coatings with SiO2 protective overcoat.
- ERF Holder cell included with soft tip threaded knobs. Tough and very light, easy to disassemble for cleaning the filter with optical wipes. Cell does not put any tension on the optics.
