SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

High level of filtering

Worked as described. A bit tricky to fold. Sun is strongly filtered so nothing else is visible.

Works as expected. Had smaller versions for the my smaller cameras for the past eclipse. Had fun after the fact to look for sun spots. So when I got my new nikon p1000 125x I had to get this due to the larger lens.

Excellent

Works perfect, got great eclipse shot with Nikon 400mm and this filter!

Pricey but Usable

Yes it's universal in the sense that if your lens outside diameter isn't too large this contraption can be bent and then taped to it - you'll have to tape it to get it to stay in place. And yes it will safely filter the sun so you can point your camera directly at the sun. However, it is just a piece of cardboard with a plastic film attached to the hole in the center. The only reason I purchased it for photographing the 8/21/17 total eclipse is because it's not too easy to find plastic film or glass with know light transmission qualities suitable for that purpose. So it worked albeit clumsily and for a one-off event using a 105 mm lens which isn't really all that suitable it was good enough.

Make sure you get the right size before you buy it

well I couldn't use it at all because it was larger than the lens it was a mess, probably it was my fault not making sure it was getting the right size for my lens.

MEASURE CAREFULLY

Works fine once folded. Its a little stiff. Be sure to carefully measure the outside diameter of the tube it is going to be placed over. I had to place it inside the tube because it would not fit on the outside. You might even want to order one size larger, just to be sure, if you want it over the exterior of the scope tube. DO NOT use your lens diameter to measure for this filter!

Seems like about 16-17 f-stops

By Robert

This filter is easy to use and attenuates the incoming light 16-17 f-stops (factor of 100,000), so looking at the sun through the viewfinder isn't too unpleasant. I secured it to the front of my lens using a rubber band. You have to be very careful to make sure it is in place before pointing the lens at the sun. My photo was taken with a Nikon D7200 (APS-C) with a Nikon 70-300 mm lens at 300 mm, ISO 200, f/8, 1/100 second. Photo was slightly cropped to center the sun in the frame.

question

Will I need this to take picture of the eclipse with my Sony A99?
Asked by: George W.
Absolutely! All cameras risk (will sustain) light sensor damage when imaging the Sun without a proper filter with the exception of the 2 minutes or so of totality of a total eclipse. This only takes place in the ribbon of totality which during the upcoming Aug. 21st event will be only 70 miles or so wide and at very specific times per location.

question

What size should I get for Canon 70-200?
Asked by: Anonymous
If you go to Daystar website or call them on the phone, I think that is where I read that if you have the 77MM pro lens, meaning it is 77MM in diameter then get the 65 - 89 Solar filter. I have the 70-200 F2.8 non IS lens. I did not put it on yet.

question

What is the difference between this product and a Neutral Density 5.4 Solar Eclipse Filter besides the price?
Asked by: Angelo
Glass in metal bezel or plastic in cardboard. The low price alternative worked well for me but I only intended to use it for one day. One plus factor is it will mount on various lenses but, If I wanted to continue with solar photography ,I'd go for the ND screw on filter.

question

I only have a viewfinder on my Nikon D3300. I assume I need to have my solar Glasses on as well as the camera solar filter?
Asked by: Dianne L.
Need to protect your eyes, that is the most important thing. My suggestion would be to keep your glasses on and mess around with the filter before the event. There will be plenty of time to take photos of the sun before the event. But keep the eyes protected and the camera lens.

question

What color does the sun appear - blue, yellow, red?
Asked by: FRANK Z.
I placed the filter on a Canon T2i with a 70-300 lense at 300mm. I use the projection view finder to find and focus the picture. I also took a 45 second motion picture. All shots result in the sun being a yellowish color.

question

What size should I get for a Nikon 18-200 lens? The current screw-on filter says 72mm.
Asked by: Dianne L.
The 65-80 MM works perfectly on my Nikon with a 72mm lens cap. Since the camera will be pointing UP, it can't just fall off. As to folding the tabs, it doesn't matter which one you start with, just fold down the little tab on the left side first (looking at the word side). The little tab will be at a 45 degree angle, Makes it easier to get the big tab located on the adjacent right side into the notch, then fold the little tab back up to hold the right tab in place.During an eclipse, you want the filter to slip off/on super easy!
