Baader IR Pass filter (1.25)
I acquired this filter approximately two years ago and have simply never used it – so time to go.
$50 (or make an offer) plus PPH – pick-up is also fine.
Please send pm to me if you are interested.
I have listed some material from the web below about the use of this filter.
"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."
PS
Please excuse dot mark in the photo - evidently my camera didn't go unscathed from my nieces fingers when she had it last weekend.
