Quick answer
If you want the widest view and dual power for competition, pick the Sirius Solar Pro. For a reliable, lightweight green dot on a budget, the Nova Green is the smarter choice.
Why window size and power source matter
The Sirius Solar Pro uses a large, high-clarity window that gives you a cleaner sight picture and faster target acquisition—ideal for competition where every split second counts. It runs on solar and battery, so you never worry about battery life in bright conditions. The Nova Green keeps things simple with a 3 MOA green dot and lightweight build, perfect for everyday carry where weight and bulk are critical.
Trade-offs at a glance
-
Window size and sight picture: The Sirius Solar Pro offers a large, high-clarity window for a wider view. The Nova Green has a compact window (24×17 mm) that still works well for typical defensive shooting. Choose Sirius for competition; Nova Green for concealed carry where a smaller window is less noticeable.
-
Power source flexibility: Sirius Solar Pro uses dual solar + battery power, so it runs on solar in bright conditions and switches to battery in low light. Nova Green is battery-only, with easy brightness control. If you hate changing batteries or shoot in varying light, the solar option is worth the premium.
-
Durability and warranty: Sirius Solar Pro is built for competition-level reliability. Nova Green is simple and dependable for daily carry. Orion Red (not compared here) offers IPX7 waterproofing and a 5-year warranty at a mid-range price. Sirius is for high-round-count use; Nova Green is for reliable everyday carry.
