Solar Warning

Only observe the Sun with ISO-certified eye protection, such as the filter found in this EclipSmart product. Never look directly at the Sun with the naked eye or a non-filtered optic. Permanent and irreversible eye damage may result.

Never tamper with or remove the permanently placed glass filters in this optic. Doing so is dangerous and will void your warranty.

Never leave your optic unsupervised. Make sure an adult who is familiar with its correct operating procedures is with your optic at all times, especially when children are present.

Never remove your eye protection when looking directly at the Sun during partial phases of a solar eclipse.

Great Solar Filter

I purchased this filter for the April 8, 2024 eclipse. It worked great and was easy to use. It slide into the front of my Celesteon 8" SCT the exact same as the dust cap that came with the scope, so snug easy fit.

If you're looking for a great white light filter for solar imaging for sunspots, this filter is perfect and easy.

Exactly what I was looking for

Fits the end of my 8se exactly. Locks in the same as the standard cover so no need to use the straps that were included. As advertised, blocks 99% of light so makes viewing the sun safe and easy.
