      Comments about Baader Planetarium Fringe Killer Minus Violet Telescope Filter:

      I my CR6 , Venus is bathed in blue.When I added this fringe killer it eliminated about 2/3 of the haze(which was very disappointing).However,when my dust cover was reduced to a 4" aperture,it removed the blue completely.

        Comments about Baader Planetarium Fringe Killer Minus Violet Telescope Filter:

        This filter has excellent light transmission and blocks much of the harmful chromatic aberration in achromats. Contrast & sharpness are increased without dimming the image significantly as most other filters do. Also the optical quality is very high with no aberrations even when used in the forward part of star diagonal or binoviewer. I use this filter permanently screwed into the diagonal of my 5 inch f9.3 Apogee achromatic refractor. The image with the filter imparts a very pale yellowish cast which is hardly noticed after a while. In my opinion this filter is superior to both the Contrast Booster and the Semi-Apo filters in apertures under 6 inches because those other filters dim the image too much. The Semi-Apo filter blocks useful parts of the spectrum in order to give an image without the slight yellowish cast and image brightness suffers because of this. The Contrast Booster is a very aggressive filter that blocks TOO MUCH of the blue wavelengths rendering poor light transmission and a stronger yellowish cast. The Contrast Booster is good for imaging with achromats or for achromats that have more CA than the Fringe Killer can handle. The Semi-Apo is actually a Fringe Killer with the Moon & Sky Glow filter combined into 1 filter.

            Comments about Baader Planetarium Fringe Killer Minus Violet Telescope Filter:

            As an astrophotographer I've noticed a definite reduction in color fringe on bright objects when using my 120mm f/5 Orion ST refractor and a DSI Pro 2 CCD imager. It's really two filters in one, fringe reducer and UV/IR filter. I considered the Semi-APO filter but the stronger Fringe Killer coating was a concern due to the light reduction when using a 120mm refractor. I mostly due narrow ban imaging any way and was looking for a filter to use in conjunction with my Orion Sky Glow Imaging filter when gathering data for the luminous layer in a 3 channel image; which this filter is prefect for.

            It stays on the end of my filter wheel and is a fine and very useful addition to the treasure chest.

              Comments about Baader Planetarium Fringe Killer Minus Violet Telescope Filter:

              This Fringe Killer is outstanding! It's a must for refractors as small as 70mm. I tried the Semi-APO filter but wasn't as impressed. the Semi-APO worked well but blocked too much light for my 90mm. The Fringe Killer not only blocked the unwanted red and blue light around bright objects but made several moons of Saturn viewable near the planet! I've placed it in my diagonal and haven't needed to remove it yet. It works well with the 70mm travel scope I own also with minimal light loss. I most certainly would recommend this filter!
