Wondering what your fellow observers are looking at these nights? Are you looking for ideas for your next observing project? This Café features a series of short presentations, PechaKucha style, by five observers, on the topics listed below, followed by Q&A and discussion.

Warren Finlay, Berta Beltran, Luca Vanzella, Jon Stolte, and Eric Klaszus will talk about:

1. What observing program(s) are you working on?
2. What do you like about the observing program?
3. What telescope do you use?
4. How do you plan and record your observations?
5. What type of star chart do you use?
6. Describe one memorable observation.

Planets under construction: how to study a million year process

Planets around other stars, also called exoplanets, are seen everywhere! In the last 25 years, thousands of exoplanets have been found throughout the Milky Way. How do we find these planets? What are the chances of discovering life there? And if they are so common, why is it that we still don’t know how they are formed? With the ALMA telescope we can now finally zoom into the birth cradles of planets: dusty disks around young stars. The spectacular images have given us new insights, but also raised many more questions on the process of planet formation.

AstroImaging Community Café March 17, 2021

AstroImaging Community Café

Wednesday, March 17, 2021
7:30 PM to 9:30 PM

Members Only event.

Due to the COVID-19 situation, this meeting will be held via Zoom.

Presenters

Abdur Anwar
Abdur will be doing a presentation on making a time-lapse of a passing asteroid using DeepSkyStacker and PIPP. Many brighter asteroids can be imaged using nothing more than a DSLR camera and lens.

Dave Mussell
Dave will be doing a presentation on NINA. He will connect to his observatory PC and demonstrate the interface, setting up sequences, and an overview of the important tabs. NINA is a great free software that is a complete solution for an automated imaging setup.

Members Only event.

_____________________________
AstroImaging Community Café is a potluck of shorter and longer presentations by astroimagers for astroimagers! Do you enjoy taking and/or viewing pictures of the sky? Are you looking for some pointers to up your skill set or turn that “nice” shot into “calendar image!”? Maybe in the last couple of months you have 5 images, or made 4 time-lapses that are too much for the AstroImaging Corner at our Regular Meetings. Whether you take 4 minutes or want to share a 20 minute backstory for a specially composed a shot, or demo a technique others can benefit from, bring it to our community! To participate: email the AstroImaging Community Café coordinator.

Stellar Obituaries

 
Cas A Supernova Remnant

Cas A Supernova Remnant. Imaged by NASA’s Chandra X-ray Observatory.

Stars have long lifespans that range from millions of years to hundreds of billions of years. But eventually all stars run out of fuel and die. When stars die, they can leave behind a white dwarf star, a neutron star, a black hole, or nothing but a bit of hot gas!
There have been a lot of discoveries in the field of stellar death in the last couple of years. In this talk I’ll introduce the main ideas behind white dwarf stars, neutron stars, black holes, and supernovae. Some of the recent observations of black holes and neutron stars include the first image of “the black hole’s shadow”, the measurements of colliding black holes and neutron stars, and observations of X-rays from binary systems containing a stellar corpse. I will provide a report on the most interesting stellar obituaries from the last couple of years, and explain what they tell us about how stars die, and how they change when they begin their new life as a black hole or neutron star.
