So, it doesn't look like this comet will be very visible from Colorado for at least 2 weeks because it's setting with the sun and rising with the sun ... and it'll be too close to the mountains for another two weeks. Maybe around Oct. 15th I'll be able to grab a photo, assuming it's still bright (looks like it's around 8.5 mag these days, but I don't see any magnitude projections anywhere).
What I'm really hoping is to photograph the M45-Moon transit on Oct. 9th, when, from Boulder, the Moon goes straight through the heart of the cluster.
