Lunt Solar 1.25" White Light Solar Wedge with Case - LS1.25HW


Lunt Solar 1.25" White Light Solar Wedge with Case

Why We Like the Lunt Solar 1.25" White Light Solar Wedge with Hard Case:

  • You can view or image the Sun in white light with this Lunt Solar Wedge (similar to a Herschel Wedge)

  • You can use your existing nighttime telescope with this Solar Wedge from Lunt Solar to view the Sun safely

  • Safely view eclipses, sun spots, and more with a regular astronomical scope using this easy-to-install and operate attachment

This Lunt White Light Wedge, only 8oz, comes with a built-in ND3 filter which allows perfectly safe imaging or visual observing of the Sun. This attachment installs easily in a 1.25" focuser on your existing astronomical (nighttime) telescope. If you wish to do visual observing, it is best to have additional dimming of the image with an optional Polarizing Filter from Lunt. This White Light Solar Wedge 1.25" version allows for using 1.25" eyepieces and has a 1.25" barrel for the focuser. Comes with a fitted Hard Case, making it a total weight of 4lbs. 1.25″ is best for refractors 4″ and under, and the 2″ is best for refractors 6″ and under.

Note: Your product may look slightly different from the unit shown in the photo!

What About Your Finderscope?

Adding this solar filter to your telescope will adequately filter the light coming through your focuser, but have you considered what you’ll do about your finder scope?

Here are some suggestions for dealing with your finder that will assure you do not damage your eyes (or anyone else’s) by looking at the Sun through your telescope’s unfiltered finder:

  • Remove Your Finder. Ditching your finderscope when solar viewing will remove the possibility of someone accidentally looking through it to spot the Sun. Of course, not having a finder makes centering the Sun in your eyepiece more difficult, but with practice, it can be done. Set the mount down so the telescope is pointing in the direction of the Sun. Put the main solar filter on so you can check your progress, and then move the telescope around until it casts a shadow that produces a nice, sharp silhouette of the scope. The OTA will look circular. Now move your telescope up or down with your hand controller, slow-motion controls, or very carefully by hand if required while looking through the eyepiece. You will not get a warning when you are close, but you should be able to align with the Sun using this method. Practice ahead of time before any big event, like an eclipse, to make sure you’ve got the process down.
  • Filter Your Optical Finder. This solution is not recommended for a reflex or red dot finder since it is too easy to accidentally look around the window. If you have one of these finders we recommend you either remove it or replace it with a dedicated solar finder (see below).

    To make your optical finderscope safe for solar viewing you’ll need to buy a piece of Baader Solar Film for Visual Use. This film comes in different size sheets and cuts easily with scissors, allowing you to make your own filter. You can go super low-tech and use a rubber band to hold a piece of the film firmly around the finder or you can get fancy and build your own slip-on solar filter. However you attach the solar film, you need to make sure there are no light leaks at all and that it doesn’t accidentally fall off when you move your telescope around. Any unused film can store flat between two pieces of cardboard and will keep for years. It is nice to have around, just in case of a solar emergency :-)

  • Buy a Dedicated Solar Finder. Check out the Tele Vue Sol-Searcher Solar Finder. This special finder can only be used when observing the Sun, but it works very well. The Sol-Searcher is reasonably priced and can be attached to your telescope with Velcro or with #10-32 screws (user supplied).
