A small amount of "spill-over" is removed by this filter. using standard 2-color fringing to "cover" unfocused purple and red fringing objective scopes with element achromatic elements. The effect is subtle, and it works best when the focus is perfect, so be careful when trying to get the sharpest image: You can concentrate on the chromatic aberration with the least amount of distortion. When exit pupils are large or magnification is low, it is more noticeable than when exit pupils are small or the magnification is high. What surprised me was how much better and sharper PLANETARY DETAILS (specifically Jupiter bands and festoons) were: Even better than the yellow, orange, green, and blue filters I used. This has been confirmed by observers who also use the much more expensive Baader anti-theft system. Filters with a fringe. I liked it so much that I went ahead and ordered the 1. To go along with the 2" model, there's a 25" model. My achro scopes are f/5 and f/8, and this filter helped the latter as well. Ivins, UT resident Waldee is an amateur observer.
I recently received the filter and used it for the first time in Bortle 7 skies in M45 " The Pleiades," an open cluster. br>There was some star bloating, which was most likely due to the 60 second subs, but the filter performed admirably. I'm pleased with the price and quality.
To sharpen the star images, I used it on a guidescope.
It's only a piece of glass, so I must have gotten a bad one or something. There is no coating, and it has no effect on the overall appearance. It's as if you're looking through a magnifying glass. With this filter on, the only thing that changes is the amount of light that is lost. Maybe I got a bad one, but this is nothing more than a piece of glass that does nothing.
This filter, which I would recommend over any other light pollution broadband filters if you have a dedicated astrophotography camera, is a must-have if you have a dedicated astrophotography camera. If you live in a light-polluted area, don't spend the money on expensive light pollution filters; instead, use this with short exposures and you'll get fantastic results.
On my camera, I'm using it to cut IR from my UV flash, which leaks some IR for UVIVF. The IR glow in the red has been completely eliminated.
It does exactly what it should in terms of reducing star bloat. I'm pleased with this filter, which came at a reasonable price.
