Aurora

Another BIG advantage to having NV is how well they show the aurora. Tonight, I saw amazing details and rapid motion from Chicagoland that were totally invisible to the naked eye. They were especially amazing near the zenith with several coronal apex displays..

Darren,
Yes, with night vision, I could see movement that I could not naked eye. Here the fir trees grow like weeds and get hundreds of feet tall. So I could see overhead from my driveway. But I drove down to the old ferry dock which has unobstructed horizon on the north side of the island. There were lots of other people there with the same idea. Thanks your suggestion, I brought my device and I’m glad I did.

Yes a 685nm filter definitely helps in light pollution.

Yes, but of course the trade off is in giving up the color and for me it is the greens, pinks, magentas, violets, and blues that make the aurora a thing of beauty. I didn't use NV on it. I am probably missing something not using my NV monoculars on their own and only using them attached to Televue eyepieces. But for me, they are mostly for faint DSOs and used to boost the view in a binocular telescope. For the aurora, it is hard to get a better "view" than a 15 sec exposure with an 18mm f/5.6 lens unless you like the look through a fish-eye lens.
