Product Info

Manufacturer Description

Baader Planetarium delivers the latest tool in the planetary imager's bag of tricks. The Baader IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. Some of the world's best amateur planetary images have been taken with this technique.

The IR-Pass filter shares the same outstanding features as all the other Baader filters. High optical quality, Striae-free substrate, and high efficiency multicoatings result in the sharpest and highest contrast image possible.

      5.0 Invisible planetary detail

      Pros:

      Cons:

      Comments:

      The build quality of this filter is top of the line. The fit and function also follow suit. This filter is pretty much intended for planetary use. It works wonders on Jupiter and Mars and effectively stabilizes the seeing conditions for you when used. It works best with scopes over 6" in size and is intended for use with a monochrome camera.

      5.0 685nm LongPass Filte

      Pros:

      Cons:

      Comments:

      Package arrived quickly and well packaged. The filter itself is for Night Vision astronomy and does a nice job of blocking out unwanted sky glow.

      5.0 Baader 685nm IR Filter

      Pros:

      Cons:

      Comments:

      I bought this after seeing other imager's pics of IR wavelength images of Jupiter. I have used it on numerous occasions and enjoy using it. I have used it on Jupiter, Saturn and Venus. Now that I have a monochrome camera, I will use it more on Jupiter, Saturn and Venus...maybe even Mars.

      5.0 Baader Planetarium IR Pass Filter 1.25"

      Pros:

      Works better than advtsd

      Cons:

      Very dark red filter,Needs a good imager,Needs a 6-in scope

      Comments:

      I bought this filter a few weeks ago and I've got to say, this is one filter to have for imaging!! I own a Meade DSI-color camera and the OEM IR-block really takes away from the image. Last night I used the IR-pass on a star cluster and at lease twice as many stars showed up on the screen. I am 100% happy with this Baader IR-pass filter.

      Strange coatings? One side is purple, the other is green, and when you look through the filter it's dark red! It's not just a planetary filter like I thought. It works on everything I've imaged, plus viewed with an EP!

      Pros: Works better than advertised; Not just on planets but on all DSOs as well.
      Cons: Very dark red filter; Needs a good imager and a 6"+ scope.
