Exellent filter for the purpose of night sky, wide field Astrophotography. Very adept at cancelling light pollution and has a high quality feel. I can not comment on the coatings, but I had no problems with light refraction or ghosting, and the filter cleans easily. I would say an upgrade from filters like the ICE filters, and the added expense to go to those brands does not justify the cost increase.

replaced my first starter tripod with this one and I am very glad I did. I have used it for astrophotography, long exposure at waterfalls, and other landscape photography. I carried it hiking at Glacier national Park as well as a couple other state parks near me. It is not the lightest tripod, but it's not bad. I had never used a ball head before and am still getting the hang of that, but it is certainly very versatile. It has done just fine on wet rocks and uneven surfaces in the various places I've used it including a running creek. I've not used the monopod function and have never had to weight it but it's an option with this tripod. Overall I have been very satisfied with this tripod.

use this tripod with an iOptron Skyguider Pro and DSLR for astrophotography. It works great for that purpose as long as I keep a low center of gravity during long exposures. When either the center column or legs are fully extended with that much weight, it does become more prone to movement but that is to be expected. I love how portable and easy to set up it is. It's great quality for the cost.

A brilliant lens adapter and a MUST HAVE if you want to take astrophotography to the next level. This lens also comes with an extended warranty. All you have to do is register on their website to extend the warranty.

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 started with astrophotography and was looking for an ultra wide angle lens with an aperture below 3 for milky way photos. On some websites this was recommended for beginners and for the price it is also affordable for hobby photographers. I am very happy with it and would recommend it to anyone

A good lens for me. price is reasonable. Use it for astrophotography and it meets my expectations.
