View or image the Sun in white light with a Lunt Solar Wedge! This diagonal-type solar filter inserts into the focuser of your refractor telescope for safe viewing of eclipses, sun spots, and more.
The Lunt White Light Wedge comes with a built-in ND3 filter which allows perfectly safe imaging or visual observing of the sun. The LS1.25HW performs best on refractors with 4" or less front aperture. As long as you can reach focus for imaging with a standard star diagonal on your night time telescope, you will be able to reach focus when imaging with Lunt Solar White Light Wedges. Note, however, that solar wedges are for use ONLY with refractor telescopes. Do not use these with other telescope designs (SCTs, Maks, etc.) since the full energy and heat of the Sun is concentrated inside the telescope tube.
The addition of a polarizing filter (not included) is recommended when using the solar wedge visually. This allows you to dim the solar image for your eyes to your liking. Simply put one polarizing filter on the bottom of your eyepiece and adjust the brightness to your comfort by rotating the eyepiece.
This Package Includes:
- 1.25" Lunt White Light Solar Wedge
- ND3 Pre-installed Filter
- Metal Carrying Case
- Die Cut Foam with room for accessories

Must have for Refractor usersPros:
Easy to Use,Lightweight,Quality Lenses,Strong Construction,Accurate,CompactCons:
I am very impressed with the contrast and detail of sunspots through this Herschel Wedge. The sun is seen as a white ball rather than orange or blue that you get from solar filters placed on the objective. This gadget makes me want to get a bigger refractor...
If you decide to get one of these, make sure to invest in a variable polarizer. It will be needed to reduce the brightness of the image.
Solar filters maybe a cheaper investment, but this can be used on any small refractor with less than 4" aperture. It's nice to know that if you should decide to upgrade your refractor, you don't need to reinvest on a solar filter for the new refractor. Alternatively, you could use it with fellow refractor users by simply changing the diagonal.
Very appreciative also that it comes with a aluminum case with foam that makes storage and transport easier.

An Essential Solar ToolPros: Cons: Comments:
I chose this Herschel wedge over using solar film because of the safety factor - no filter cell subject to punctures, gravity, wind and curious children's hands. That's why these devices are also referred to as safety wedges.
I use this with an 80mm ED refractor. Its quality build is apparent. It provides very impressive and contrasty views given the seeing conditions, and resolution capacity of my small scope. I like the design of the heat trap, which doesn't get overly hot.

Accurate,Lightweight,Easy to Use,Strong Construction,CompactCons: Comments:
I have used thin film and glass filters for white light solar observing and previously owned a Herschel Wedge but sold it. This Lunt is much better than the previous wedge in terms of fit & finish and I like that the neutral density filter is an integral part of the wedge so it cannot be accidentally left out. In use, the wedge seems superior to film and glass filters, revealing more detail through my 4" refractor; as long as you add a single polarizing filter or a Solar Continuum filter to your eyepiece. Without the additional filter, the image is awash in light which effects contrast. I use an inexpensive polarizing filter which does not turn the image green like the Solar Continuum. White light views are great through this Lunt wedge. It's the best I have used.

An Excellent Solar WedgePros:
Compact,Strong Construction,Easy to Use,AccurateCons: Comments:
Used with a 70mm ED refractor, the 1.25" Lunt wedge gives me the best contrast, sharpness and detail I have seen in a white light solar image. It is well conceived and executed. As an example, the eyepiece holder is a bit taller than a conventional diagonal to accommodate filters. I use a single polarizer, which is comfortable at maximum, and a 1.8ND which is most comfortable for me. You will definitely need some form of final energy absorption as the image is uncomfortably bright without it. This wedge very efficiently dumps much of the energy to a heat sink at the rear of the unit. The sink never actually gets hot with a 70mm objective, warm, but not hot. This is a nice bit of work from Lunt at a very reasonable price.

Polarizer Not IncludedComments:
I shoot thousands of Solar images over the course of the year. I have several types of systems including the film time solar filters and wedge type filters. One thing the wedge filters have in common is that they require a lot of "in" focus from your telescope. It is difficult to get my 100mm through 60mm scopes to focus using a 2" version of the solar wedge but this 1.25" focuses easily and works with all my scopes in those size ranges. The images are considerably sharper with a wedge like this than the best solar film and allow you to see a higher level of contrast. This wedge is built really well is also extra safe to use because it has an internal system that blocks and absorbs the exist beam. The engineering behind it was well thought out. This is now my go to filter for white light imaging.
