What makes the Lunt 1.25" Herschel Wedge better than a front-mounted solar filter?
A Herschel wedge provides superior image contrast and sharpness. Because it allows the main objective to form an image with unfiltered light, it avoids the slight image degradation caused by light passing through a front-mounted filter. This results in finer, higher-contrast details in sunspots and solar granulation.
Is the Lunt 1.25" Herschel Wedge safe for my eyes right out of the box?
For imaging, yes. For visual use, you need an additional filter. The built-in ND3 filter reduces the sun's brightness to a level safe for cameras, but it is still too bright for comfortable and safe visual use. For observing with your eyes, you must add a polarizing filter to your eyepiece to further dim the view to a comfortable level.
Can I use the Lunt 1.25" Herschel Wedge on my SCT or Newtonian telescope?
No, absolutely not. Herschel wedges are designed for use with refractor telescopes only. Using a wedge with a reflector or catadioptric telescope (like a Schmidt-Cassegrain or Maksutov) will cause a dangerous buildup of heat inside the optical tube, which can permanently damage your telescope and cause severe eye injury.
What is the maximum aperture telescope for the Lunt 1.25" Herschel Wedge?
The Lunt 1.25" Herschel Wedge is designed and rated for use on refractor telescopes with an aperture of 4 inches (102mm) or less. For refractors larger than 4 inches, you must use the 2" Lunt Herschel Wedge.
How do I adjust image brightness with the Lunt 1.25" Wedge on my 80mm f/6 refractor?
For visual use with your 80mm refractor, first thread a standard 1.25" polarizing filter onto the barrel of your chosen eyepiece. After inserting the eyepiece into the wedge, you can simply rotate the eyepiece. As you turn it, you will see the image of the sun get brighter or dimmer, allowing you to set the view to your personal comfort level.
Will I see solar flares or prominences with the Lunt 1.25" Wedge on my Tele Vue 76?
No. The Lunt Herschel Wedge is a white-light solar device, meaning it shows the sun's surface (the photosphere), where you can see sunspots and granulation. Solar flares and prominences are features of the sun's atmosphere (the chromosphere) and are only visible in dedicated Hydrogen-alpha solar telescopes.
