This glass carrier-mounted solar filter, allows safe solar observing with a telescope. The glass filter has impressively high contrast and is very durable. This is ensured by
- multi-coated glass with chromium-nickel alloy coating allowing only 0.001% of sunlight to pass through (neutral density ND=5)
- sturdy aluminium mount - light, rustproof, long-lasting!
- the inner part of the mount is covered with foam rubber - which holds the filter securely in place by friction alone. The screws on the mount are for added extra security only.
A glass filter of this quality makes solar observing and astrophotography a joy. The filter can be safely and rapidly mounted.
