NiSi 77mm zonfilter Nano UV/IR Cut ND100000(5.0) 16,6 stops

The image through this filter is incredibly sharp—no weird color casts, just a clean, dark sun for my eclipse shots. It’s solidly built and screws on smoothly, which I really appreciate for such a specialized piece of gear.

I can finally shoot the sun without hunting for a perfectly clear sky—the 16.6 stops of reduction let me keep the shutter open long enough to catch detail in the corona, and the UV/IR cut means colors stay true instead of washed out. It threaded onto my lens smoothly and didn’t add any weird vignett

Finally, a filter that lets me shoot the sun without washing out the sky—the 16.6 stops of density make the corona visible during totality. The UV/IR cut is a nice bonus, keeping the color accurate without adding a magenta tint.
