Lunt LS50C Compact Double-Stack Filter

I ordered the 50mm double stack with high hopes that it would arrive for a daytime outdoor event, SpaceBurgh, in downtown Pittsburgh's Market Square. The event was slightly more than the 8 week shipment period Lunt has posted. A week after placing my order, I sent a message to Lunt explaining that I'd love to have this by that date, and they promptly replied that they can't guarantee it will arrive in time, but they'll do their best, as they were waiting on materials to build my order. Well, it arrived a few days before the event, was a huge hit with the public, and for me, the viewing through it is far better than I expected. I'd give this seven out of five stars if I could.
