I purchased this filter after reading many reviews. I used it for the Total Solar Eclipse a couple weeks ago. It was awesome. The filter provided great visual images. I didn't try any photography with it this time fort I'm still trying to figure that part out. I used the filter with my Celestron EVO 9.25 and am totally pleased with the performance of the filter. I would definitely recommend this filter to everyone interested in doing some solar viewing.

I got this filter to attach to my telescope for the 2017 solar eclipse. Optically it performed great and everyone had a good time looking at the sun slowly disappear, at the sunspots, and at the chromosphere for a few short seconds. In addition to being good optically, the filter itself seems to be well made. Where things falls flat though is the mount. Other reviewers have stated that correct sizing is critical so before getting this I measured the tube diameter of my scope under the assumption that this was the necessary measurement. Apparently it is not. A 150mm filter is grossly oversized for a 149mm tube. The 150mm appears to refer to the size of the aperture though which the filter transmits light, while the mounting system is several centimeters larger in diameter. Baader Planetarium does have sizing guide, but it is hard to find. Additionally, the mounting system uses glue-backed Velcro pads that you stick onto your telescope for safety. The idea is nice but the execution here also falls flat. The glue is not particularly well adhered to the Velcro pad and tends to pull off before the Velcro separates. Also, some might not like the idea of having Velcro pads glued onto their scopes, binoculars, or (especially!) telephoto lenses.

This was a last minute purchase and I was not sure if it would even fit. Thankfully it fit onto the lens hood of the lens.

The filter assembly is well made and high quality. It fits the lens perfectly, but just. The only way to attach this particular filter is to install it on the lens hood. It has three rubberized posts that are slightly adjustable to accommodate different dimensions, but the range of adjustment is quite small (approximately 3mm per post). I set my posts set as far inward as possible and in this position it is possible to insert them carefully into the lens hood and force them down until the rim of the filter frame is against the lens hood. There are also three Velcro straps to secure the filter from accidentally coming off. I have taken several sets of trial images and have not noticed any light leakage or occlusion of the sun's disc. I would recommend that anyone considering this filter check the specs carefully to get the correct size for proper fitment. This particular filter would not attach properly to a tulip style lens hood.

Great item for both visual and photography of the sun through your telescope.

Very well made product that fits my Celestron 7" Maksutov perfectly.
Be captivated by the celestial wonders with the 100mm AstroSolar Telescope Filter by Baader Planetarium, a renowned name in the world of astronomical equipment. This high-quality filter is designed to enhance your stargazing experience by reducing light pollution and increasing contrast, allowing you to observe planets, stars, and other space phenomena in vivid detail.
The AstroSolar Telescope Filter is crafted with Baader's AstroSolar Safety Film OD 5.0, a product of 15 years of innovation. Unlike many ready-made filters that stretch the filter material, compromising image quality, this filter ensures the AstroSolar film is mounted stress-free, preserving its high precision optical window. This results in a superior viewing experience, even at high magnifications.
The filter is housed in a clear white IR-rejecting front ring with raised edges, designed to protect the solar filter material from any sharp metal edge. It features a user-friendly, no-tool mounting system with adjustable centering bolts, accommodating a wide variety of mechanical tube diameters. The filter also includes non-rotating sliding fasteners made from durable aluminum, equipped with a machined indicator for easy adjustments.
For added convenience, the AstroSolar Telescope Filter comes with an index scale beside each adjustment slot, allowing for fast and repeatable adjustments. It also includes black sliding washers to block sunlight from passing through the filter cell, ensuring optimal viewing conditions.
Safety is a priority with this filter. It includes three security straps to secure the filter cell with Velcro-adhesive pads, ensuring a secure fit in front of the telescope under any circumstances. A warning text is also printed onto the front side of each filter cell, reminding users to read the instructions before use.
The AstroSolar Telescope Filter is suitable for solar observation and photography with all high-end telescopes and extreme tele-lenses. It's designed to retain its excellent optical quality at any temperature, from -30Deg C to +50Deg C, ensuring no astigmatism during winter observation or with temperature changes in summer.
Experience the universe like never before with the 100mm AstroSolar Telescope Filter, a testament to Baader Planetarium's commitment to quality and innovation in astronomical equipment.
