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.

      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.
