I found the Helios Solar to be a high quality build and well designed filter. It’s genuine ISO certified to protect your eyes and expensive camera lens and sensor from the damaging visible, UV and IR wavelengths. The ND5 glass is high quality and should last a lot longer than an inexpensive mylar film alternative, which is susceptible to tears and holes that render them useless. After using the Helios filter during the Aug. 21, 2017 solar eclipse, I was amazed at the clarity and detail that my DSLR and 600mm f/4L prime lens were able to capture with the aid of the filter. Sun spots and granulation are distinctly visible (see attached photo). Well done, Seymour Solar!
The staff at Seymour Solar gave great advise and service when I was ordering my solar filters. Used these filters during the eclipse and they worked perfectly! I now have several vivid photographs of this great experience of witnessing a total eclipse.
Purchased a solar filter for my 4.5" scope and the site had a helpful guide to make sure I ordered the right size. I received updates on the package mailing and the filter itself is exactly what I was looking for. Very competitive price too.
Use of Seymour Solar filter on 8/21/17, Epic Total Solar Eclipse
The use of a Seymour Solar filter on our 8" Celestron Telescope operated flawlessly. Many adults and many, many children got the first contact through last contact views for their first time in their lives. They may never forget this image! This event was observed on a rise located very near Shoshoni, Wyoming. Thanks for a fine quality, economic product.
I purchased 2 sets of filters to my astronomical binoculars and 1 for my digital camera. I also bought 10 pairs of solar filter glasses for easier viewing for the grandkids. I am not an expert photographer and had very little knowledge of the proper camera settings needed. But without the filters all would have been lost. As it turned out, we had excellent viewing conditions and the filters did their job. Without the filters, we wouldn't have the memories saved of that day. The inexpensive solar filter glasses were a hit with the kids (and the adults, too). It was my first total solar eclipse (I'm 69 yrs old). It was an emotional and almost religious experience. We drove 18 hours from NJ to Tenn. Rochester NY is only about 6 hours away, so God willing, I'm looking forward to using them again in Rochester NY in 2024.
About a week before the eclipse, I remembered the solar filter for my camera, had been stolen from storage. I went online to see if I could find one. I looked everywhere, and all the suppliers were sold out, or back ordered. Seymour Solar, like everyone else, was sold out of the size I needed. Then I noticed something that I hadn't seen anywhere else, a used equipment page. So I checked it out. They had two used solar filters, and they were both the size I was looking for. I jumped on the opportunity, and it was only fifty dollars, for a real glass filter. That was half the price that I expected to spend. The question was now, "will it get here in time?" It arrived five days later, three days before the eclipse. The filter was in great shape, with only a couple of pin holes in the coating, that were easily remedied. Thanks guys, you had just what I needed when I needed it. You rescued the eclipse observation for a half dozen of us. Thanks again!
Before the August eclipse I purchased a filter for my spotting scope and a pair for my binoculars. Both of them worked perfectly for the eclipse, providing detailed views of all phases before and after totality. We could watch as several sunspots disappeared behind the moon, and watch the last sliver of the sun disappear into totality. We viewed the eclipse near Glendo, Wyoming, and shared scope views with at least fifteen other people through the event.
Very pleased with the Seymour Solar filter I used for the 2017 eclipse. I wasn't sure of the correct size needed since I was using a Canon 300 L 2.8 lens. but customer service helped me find the perfect fit and the Helios Glass Solar Filter work perfectly! I've even used it since the eclipse having fun photographing sunspots and flares!
I used my 58mm Seymour Solar photo filter on my 70-300mm Nikkor zoom lens with my D3200 to photograph the total Eclipse of the Sun from Leslie MO. It worked fine and I got several great shots of my first total Eclipse of the Sun. (I reserve the right to all my photos, please credit accordingly).
Got the 86mm glass solar filter to use with a 150mm-500mm lens for the eclipse. Worked like a champ! Quite happy with the purchase.
I purchased the filter 1 week before the Eclipse on Aug 21, it was a last minute trip to the totality zone...best money I have spent in a while! Thanks Seymour, it made the experience that much better!!
