Australia solar eclipse 2028: glasses and filter buying checklist
The total solar eclipse crosses Australia on 22 July 2028, including Sydney. Check the Astronomical Society of Australia’s path information for your viewing location. Australia is not entirely inside the totality path. Before buying equipment, decide whether you will watch directly or through optics: those require different protection.

In short
For direct viewing of the bright Sun, use an undamaged purpose-made solar viewer meeting ISO 12312-2 from a verifiable supplier. Sunglasses do not substitute.
Binoculars, telescopes and camera lenses require appropriate solar filtration at the front, securely fitted before pointing towards the Sun. Do not look through them with eclipse glasses.
A filter marked “80” does not promise a fit to every 80 mm telescope. Measure the mounting diameter and match the exact visual filter and its manufacturer instructions.

Date, location and totality
Date, location and totality
The ASA eclipse page gives 22 July 2028 and path information. Check an exact observing site, not a city name alone. This guide does not supply verified local contact times or durations.
Direct viewing of any bright part of the solar disc needs proper protection. The naked-eye exception applies only during the brief fully total phase at a site inside the totality path, with the timing properly established. If you are unsure, keep the protection in place or use a supervised astronomy event. A calendar date is not a countdown to remove a filter.
Three different purchases
Three different purchases
Dedicated solar binoculars with permanent filters have a buying limitation: the filters cannot be removed for a view of the faint corona during full totality. They are for filtered viewing of the bright Sun. If observing the corona is your goal, plan a properly timed direct totality view or a supervised astronomy setup instead; do not alter the permanent filters.
| Viewing method | What to check before buying | What does not establish protection |
|---|---|---|
| Direct-viewing solar glasses / handheld viewer | ISO 12312-2, verifiable maker/supplier, condition and instructions | Dark sunglasses; an unverifiable printed ISO claim |
| Dedicated solar binoculars: EclipSmart 10x25, 71237 | The exact solar product, intact permanent objective filters and manufacturer instructions | An ordinary 10x25 model, even from the same brand |
| Solar filter for an existing instrument | Visual/photographic purpose, filter material, actual tube fit, secure front attachment and other optical paths | A family name, an “80” size or telescope aperture alone |

Worked example: an 80 mm label is not a fit
Worked example: an 80 mm label is not a fit
The current Baader clamping table lists visual ClearWhite ASTF 80 as 2423010, OD 5.1, and photographic BDSF 80 as 2459370, OD 3.8. Both show an 80 mm clear aperture and an indicative instrument aperture range of 70-90 mm. Those are not the tube clamping diameters.
For outer mounting, ASTF 80’s stated range is 110-140 mm with 10 mm bolts, or 100-130 mm with 20 mm bolts. For example, a measured 105 mm outer tube is outside the 10 mm bolt range but inside the 20 mm bolt range. That still does not prove the supplied filter will seat securely or clear other fittings.
Check the exact revision in the seller’s listing against the current manufacturer documents. Older AstroSolar versions and codes may differ. Do not silently substitute an old code for the current visual product.
Four mistakes to avoid
Four mistakes to avoid
- Wearing eclipse glasses behind optics. Unfiltered magnifying optics can concentrate sunlight onto the viewer. Fit proper front filtration instead and follow optical-filter guidance.
- Buying a photographic filter for visual use. The BDSF OD 3.8 listing is not the ASTF OD 5.1 visual listing. Match intended use and product code.
- Filtering one binocular objective. Both light paths need proper protection. Check every objective and any finder path before use.
- Treating a supplier list as blanket approval. Check the exact maker and product, condition, instructions and current supplier information. A marketplace seller name or logo does not prove authenticity.
A shopping plan before eclipse week
A shopping plan before eclipse week
Choose a site and viewing method.
Use the ASA path information and decide between direct viewing, your own instrument or a supervised event. Do not buy a telescope just because the eclipse is total somewhere in Australia.
Record the exact protection product.
For glasses, identify maker and a verifiable supplier. For optics, record visual/photographic purpose, product code, mounting measurements and the manufacturer’s fitting instructions.
Check authenticity and condition.
Use the current AAS supplier information and manufacturer documents. Inspect the product when it arrives and before every use. Do not use damaged filters.
Compare eligible offers.
Match exact product, pack count, revision, availability, tax and membership conditions. Compare verified item prices; show shipping separately. Muchita does not certify equipment safety.
Where to start your supplier check
Where to start your supplier check
The AAS supplier list is a starting point for direct-viewing viewers and solar-filter suppliers. Read its scope and identify the actual manufacturer. This guide does not claim that a particular Australian retailer has stock or delivers to your address.
Questions and answers
Fair questions,
plain answers.
When is Australia’s 2028 eclipse?
22 July 2028. Check the ASA path information for your exact location; not every Australian location sees totality.
Are ordinary sunglasses enough?
No. Use appropriate direct-viewing solar protection; darker sunglasses are not a substitute.
Can I wear eclipse glasses while looking through binoculars?
No. Use properly fitted front solar filtration for the binoculars. Do not place direct-viewing glasses behind unfiltered optics.
Does ISO 12312-2 cover telescope filters?
No. The standard covers direct-viewing solar viewers. Optical filters need appropriate material, mounting and use instructions for that instrument.
Is Baader BDSF 80 the visual ASTF 80?
No. The checked current table labels BDSF OD 3.8 as photographic, while ClearWhite ASTF is the OD 5.1 visual version.
Can I use a filter just because my telescope is 80 mm?
No. Aperture and tube mounting diameter are different. Check the exact clamping range and secure attachment instructions.
When can I remove eclipse glasses?
Only during properly established full totality at a site inside the path. This page supplies no verified contact-time countdown. If unsure, keep protection in place or use supervised viewing.
