Solar Filter (ND 100000)

Big solar events are coming next year.  Hutech will carry Japanese-made high-quality solar filters.

KENKO 67mm ($149.00)

MARUMI 77mm ($189.00)

These are a kind of must-item for solar imaging. Marumi 77mm will be available from next week while Kenko one will be end of December. BORG solar packages will be announced shortly.

  1. Hey Ted,

    That looks like a useful product.

    Could a solar filter, like one of those, be used on a camera lens attached to a DSLR for solar imaging?

    The 77mm size would fit directly onto the Canon 70-200mm f/2.8L EF II well-regarded zoom.

    Thanks for the info!

    Best wishes,


  2. Perry,

    Thanks for your quick comment. Yes, you can set a filter by same way as the conventional filters


    • Ted,

      I wasn’t so much worried about connectivity as I was the amount of heat transmitted to the camera innards.


  3. Perry,

    Don’t worry., this is promising item. No heat inside much. These filters reduce the energy at 1/100000. I don’t sell unknown or non-promising items.


  4. Ted – please confirm that this filter limits the intensity of the sun’s rays and does not reduce the band pass to a fraction of an Á like a Lunt solar scope? I own Baader SolarSafety Film that I used to create a filter for my 80ED. The obvious benefit of your filter would be that it will work with my camera lenses.

    • Don,

      Yes, this is the neutral density(1/100000th) filter optimized for solar imaging with today’s digital cameras. Not narrowband filter.
