Transcript

oops okay there we go okay in theory we are alive hey everybody welcome to the virtual star party for man what is it Sunday do you time has no meaning anymore 2020 January June June June 7th 2020 of course I'm Fraser Cain publisher of Universe Today we've got a couple of telescopes tonight my telescope is out of commission and I don't mean mine it'...

Key Insights

• 😚 Winter objects are favored for imaging due to their closer proximity in the Milky Way.
• ❓ Astrophotographers may prefer imaging nebulae over galaxies for color and contrast.
• ❓ Astronomers capture images of galaxies in various stages of interaction and galactic cannibalism.

Questions & Answers

Q: What causes the trails in the images captured during the star party?

Trails in the images are due to wind gusts causing the telescope to move slightly during exposure, resulting in the star trails.

Q: How do astronomers choose which objects to image during a star party?

Astronomers may target specific objects based on their visibility during certain seasons and their personal preferences in astrophotography.

Q: Why are winter objects in the sky favored during imaging sessions?

Winter objects are often closer to us in the Milky Way, making them appear larger and more detailed in images compared to galaxies millions of light-years away.

Q: What distinguishes nebulae from galaxies in images?

Nebulae are often seen in true or false color due to ionized hydrogen emission, while galaxies typically appear larger and are harder to capture through light pollution.

Summary & Key Takeaways

• Astronomers capture images of galaxies and nebulae during a virtual star party.

• Telescopes provide views of celestial objects like the Iris Nebula and the Sunflower Galaxy.

• Discussion includes galactic collisions, galaxy cannibalism, and the beauty of astronomical objects.
