Description
Product Description
Variable Poarizer is effective for eye observation of high brightness celestial objects such as the moon and Venus.
Consists of two polarizing filters, one piece can be rotated 360 degrees. Rotate to change the amount of light transmittance, so you can adjust the light to the best viewing angle.
You can adjust the amount of light transmitted to your preference, making it perfect for lunar observations. For example, the transmittance of the filter can vary depending on the age of the moon, which makes it much more convenient to use than a typical moon filter.
Note:
There is a glass retaining ring on the front of the filter so the accessories cannot be mounted.
