Great tripod to use in any environment. Easy to use and great versatility!

The filter has the size of 10x10cm, weighs 47.5 gr and is 2mm thick, so it matches the filter holder from the same company. Made of anti-reflective glass, it allows to eliminate the noise caused by artificial lights (that is, the yellow part that appears below in the photos of the Milky Way, due to the city's artificial lights). The difference without the filter is noticeable, although a good post-production process will keep the artificial light while the filter is fully cut. With long exposures for the Milky Way, the amount of light captured by the sensor decreases slightly, but the raw power is rich in information and makes it possible to recover the Milky Way and the whole starry sky. It's possible to overcome this (i.e. capture more light) by using a tracker star or taking multiple shots (in my case, without a tracker star, with an f2.8 to 11mm, the max time to not getting the movement of stars is 30seconds). Even in the city it does its job eliminating that yellowish gradient in the sky and bringing out the beauty of the night lights.

I love this tripod! Best one I own.

needed a sturdy tripod for portable astrophotography with my DSLR and a telephoto lens with my little launch tracker. This tripod is VERY stable, just what I needed. Highly recommended for portable space photography!

I bought this tripod and it works great.

This is really great tripod. Light, stable and easy to set up.

Best Tripod out there.

The tripod is well made and very sturdy. It supports a decent size camera very well and it should hold a star tracker as well as the camera just fine.
