Hale-Bop was pretty cool
I had to drive far away from the city, because when I looked up (at my house) I saw nothing
I was expecting a small splotch of light with a tail- it was like 1/4 OF THE SKY!! at least 5 times the width of the full moon
I used a Russian-surplus light-intensifying scope, out in the country, and found I didn’t need it, but it did expand the apparent size to more like 1/3 the sky (IIRC).
