As mentioned here briefly before, IDAS’s unique UV/IR blocking filter is now available. It’s HEUIB-II.



You will see how HEUIB-II blocks UV/IR while creating good color balance for modified DSLRs and one-shot cooled color cameras.  All are taken with modified 6D in AWB mode and no image processing made at all.

uvirConventional UV/IR – this color balance should look familiar to all of them




It is obvious that we don’t need any discussion about that. If light pollution is not issue and you are looking for UV/IR blocking filter for your camera, this is it. Probably I guess stars will become more colorful than with LPS-V4 while isolating H-alpha emission because of wider bandpass. LPS-V4 create highest contrast at H-alpha. But unfortunately we lose color of stars. Meanwhile, conventional UV/IR blocking filters are good for maintaining star colors. But background is totally reddish as shown above. The reddish background is hard to isolate faint red nebulosity from the background.

I’m sure this filter should make imaging processing relatively easier since the original background color is more neutral. Let’s see how it works.  I will take some astro shots and will show the result here.

48mm, 52mm, 37mm and 36mm without frame are available.

  2. Will larger sizes be available for lens use? 67mm, 72mm, 77mm?

    • So far, there is no plan on our table. But let us think about that.
      Current solution is MFA for APS size. We are planning Canon full frame camera adapter.
      Since HEUIB-II can’t be used with wide-angle lenses like other IDAS filters, the body-mounted
      is better way to go.
