Comet 46P/Wirtanen
Comet 46P / Wirtanen is approaching Earth and is visible in the night sky. The comet is very large, the glow is 2-3 times the size of the moon as we see it, but faint (magnitude 5). It will be at its brightest on December 16, when it will be closest to Earth and have a magnitude of 3 (smaller number is brighter). The comet's path is essentially going over Orion, see it here and in the photos section: This is a self-assignment, but we may schedule an actual event. Watch this space. Wirtanen will be visible after dark in the eastern sky, the best time window is 8-11 pm (it comes over the horizon at 7, dips below at midnight). Read more information go to There are two ways you can try to capture the comet: just by itself with a long lens, doing Astrophotography, or with some landscape in the foreground for an astro-landscape photo. For a sky-only photo, you can take it from anywhere, as long as the comet is high enough in the sky to get past the lights. You can use a sky tracker, if you have one, to increase exposure time and reduce ISO. If you want to do an astro-landscape photo, you need a dark location (east coast of Cape Cod, Rockport, any state park or lake looking east). You will shoot this at high ISO and short exposures (15-20 s). The comet is quite large in diameter, but because we look right at its front, the tail is not visible to us, as it is "behind" the comet from our viewpoint. It looks like the comet has a green tint to it. Our friends at National Parks at Night have a nice write-up about it:

What we're about

This is a collective of people who share a passion for night photography.

This Meetup is about gathering in groups, small or large, to capture the night and share the outcome with each other. Education, respectful and constructive feedback, exhibition of images and socializing during and after our gatherings are all part of our activities.

We will explore old, new, popular and exotic places in the greater Boston area, southern New Hampshire and Maine, Rhode Island, northern Connecticut and central Massachusetts and there are occasional field trips to places such as New York or Maine. Inner city nightscapes will be as much part of our portfolio, as will be dark sky star, astro-landscape and Milky Way shoots or light painting opportunities.

Most events are free, membership dues will cover costs, minor group expenses and promotional means, invited lectures and trip organization expenses. Some events may incur further cost (if the venue charges us), as announced in those meetups. You can sign up for free and see if this is for you during the trial, but paid members may be given priority for limited attendance meetups. Note that this is the only continuously active night photography meetup in New England, we average one photo shoot every ~10 days, one meetup every week, and even keep it alive throughout the winter. Browse our "past meetups" to see what we have been doing.

Night photography is exciting, presents the world in a truly different light and is serene and calming in many ways. However, it is also very different from daytime shooting, sometimes physically taxing and requires to watch out for yourself and others. The meetups here will always be conducted with adult and mature members, who provide safety through numbers, but you will always be responsible for your own safety.

Before you get started, please read the group policies: and please take a moment to answer some questions about timing and gear under MORE - POLLS in the menu.

We are looking forward to seizing the night with you!
