Antares 2″ Variable Polarizing Filter
The Antares 2″ Variable Polarizing Filter Reviewed by Jerry Lodriguss
I have been using the original Antares Variable Polarizing Filter (VPF) for a number of years and have been very happy with it. I purchased the new model, the Antares 2″ VPF recently. Here are my thoughts.
– The filter is still very well made. The housing is all metal with a knurled aluminum ring to attach it to the eyepiece. The glass is high quality.
– The new design eliminates the need for a separate spacer ring. This was always a pain to keep track of with the old model.
– The new filter has fine threads that allow it to be screwed directly into 2″ eyepieces without an adapter. This is a great feature!
– The filter can now be rotated while attached to the eyepiece, which makes it much easier to use. With the old model, you had to remove the filter and rotate it, then screw it back in. This was a real pain, especially if you had a heavy eyepiece in place.
– The new filter is said to have improved light transmission. I can’t speak to this, but it does seem slightly brighter than the old one.
– The main downside of the new design is that it is no longer possible to stack other filters on top of the VPF. This was always a great feature of the old model, and I will miss it. For example, if I wanted to use both a nebula filter and the VPF, I could screw the nebula filter into the VPF. Now I’ll have to use two separate adapters, which is a pain.
– The new filter also requires a larger clear aperture in your eyepiece than the old one did. This means that if you have any 2″ eyepieces with a small field stop (such as some Plossls), they will vignette with the new VPF in place. This was not an issue with the old model.
Overall, I’m happy with the new Antares 2″ VPF. It’s a high quality product that represents an improvement over the old model in many ways. However, the loss of the ability to stack filters is a significant downside.
Lumicon 2″ Variable Polarizing Moon Filter
If you’re looking for a good polarizing moon filter, the Lumicon 2″ Variable Polarizing Moon Filter is a great option. It’s easy to use and provides good results.
The filter is made of two pieces of glass that are glued together. The top piece of glass has a circular polarizing film on it, and the bottom piece of glass has a linear polarizing film on it. The two pieces of glass are rotated with respect to each other so that the amount of light that passes through the filter can be varied.
The filter works by blocking out some of the light that reflects off the moon’s surface. This makes the moon appear darker and reduces its glare. Thefilter also reduces the amount of light that is scattered by the atmosphere, which makes the moon appear sharper and more detailed.
The Lumicon 2″ Variable Polarizing Moon Filter is a good choice for anyone who wants to improve their view of the moon. It’s easy to use and provides good results.
Thousand Oaks Optical 2″ Glass Solar Eclipse Filter
On August 21, 2017, a total solar eclipse will be visible in a band across the entire contiguous United States, making its way from Lincoln Beach, Oregon to Charleston, South Carolina. Along this path of totality, the sun will be completely covered by the moon for up to 2 minutes and 40 seconds, turning day into night and offering a breathtaking view of the sun’s corona – the outermost atmosphere of the star.
As this rare event approaches, many people are wondering how best to view the eclipse. While sunglasses will protect your eyes from the sun’s harmful rays, they will not allow you to stare directly at the sun during the eclipse. Instead, you will need to use special eclipse glasses or filters in order to safely view the event.
One option is the Thousand Oaks Optical 2″ Glass Solar Eclipse Filter. This filter is made of thin black polymer material that is mounted on top of optical glass. The filter allows you to view the sun safely during the eclipse by blocking out more than 99.999% of sunlight and reducing glare.
The Thousand Oaks Optical 2″ Glass Solar Eclipse Filter is available for purchase on Amazon.com.
