Is it better to buy a complete amateur astronomy telescope system that includes optical tube, mount, drive, etc or can you get better quality by assembling your own from individual components.  Dustin talks advantages and disadvantages to both.

Tony is finally getting to a place where he can start construction on his backyard observatory for his 20 inch reflector.  In this episode, we discuss the value of having a permanent place for your telescope and it doesn't have to be fancy!

We have a guest today!  Beth Johnson from the SETI Institute kindly agreed to join us to talk about her role at the SETI Institute and what they are doing to help us find signs of intelligence in the universe.  

Tony's been thinking a lot out his life and the meaning it holds.  Getting philosophical, Dustin helps Tony realize that autoguiders are the key to understanding.

Dustin has been using the new line of astrographs from Askar/Sharpstar and tells us a little about them.  Astrographs are more ubiquitous now that imaging has become so mainstream.

Tony also talks a bit about whether you need a college degree these days to get a good job in astronomy.

Dustin's been using some of the new iOptron mounts that have recently come out and he talks about his experiences with them.  Tony wonders about the effects of the growing use of LED lighting in cities and towns across the world.

We're Podchatting, did you know that? Tony ventures into the realm of saying what's on his mind.  Dustin and Tony discuss the Artemis mission and Tony has thoughts.  They also talk gear, astrophotography and lots more. 

OK so we decided to pick this back up again.  Tony and Dustin are back talking astronomy and telescopes and we hope you'll join us!  Please send us any input you have and you're always welcome to join our discussion if you're interested.

This episode was prompted by an email from Matt who wanted to sort out WHY different telescopes are better than others.  In this episode, I'll break down all the different telescope types and try to answer the question of why you should want one.

Also, Dustin and I discuss camera resolution: why it matters, is more better and more.

More than any other aspect of amateur astronomy, using your equipment to get involved in professional astronomy is growing the fastest.  In this episode, we explore ways you can use your stuff to do science!  Also, Dustin and Tony talk about the advances in short-focal length telescope design and why they are amazing.

We've been listening for signals from the galaxy hoping to detect another civilization out there.  What are the actual chances we'll hear anything?  Let's take a look at this paper and find out: https://arxiv.org/pdf/1007.0850.pdf

Dustin and Tony also talk about APO refractors and catadioptric telescope systems.

The study of planets around other stars, exoplanets, is a brand new field, one that closely tracks my career as a software engineer in professional astronomy.  I've had the privilege to watch our knowledge about exoplanets explode: in just a few decades, we've gone from not being sure there were other planets around other stars, to knowing how many there are in our galaxy, their types and in some cases, we can guess as to whether life may be present on them.

Let's talk about this as well as Dustin and I discuss what you should think about when imaging your first night sky object.

Oh, and I got an email!

In recent decades, our knowledge of what black holes are, how many and what types, has exploded.  Coupled with the brand-new field of gravitational wave astronomy, we are poised to learn even more.  Let's take a tour of what black holes are, the different kinds and how many of these enigmatic objects there are in our universe.

The magnetic field of the Earth is undergoing some changes.  Scientists measuring the strength and direction have noticed a weakening of the magnetic field along with movement.  Is this something to worry about?

Dustin Gibson and Tony also discuss smart telescopes along with computers designed to run imaging equipement.

Winter is a great time to see Orion the Hunter, let's talk about that.

Can we terraform the Moon?  It's a better idea than terraforming Mars believe it or not.  Dustin and Tony discuss putting together an astrophotography rig for beginners and some space news.

Imaging with filters can dramatically improve the signal to your camera allowing for much higher quality images.  The question of which filter to use on what object can be daunting.  Dustin and Tony dive into the topic of filters, specifically narrow band filters to give you insight on what they are, what you can get from using them and what to look for in a good filter.

At long last, the launch of the next big NASA flagship telescopes: JWST is ready for launch, sitting atop its rocket and awaiting good weather.  This telescope marks the pinnacle of ambition for NASA as it is doing something that has never been done before.  Launching a telescope of this size is a first for the human race and promises to bring us insights about our place in the universe like nothing that has come before.

Humanity will look farther into the universe than ever and JWST, the most technically advanced and capable telescope ever built, will collect light from a time when the very first stars and galaxies were born.

In this episode, Dustin and Tony talk about this amazing telescope, and we answer a listener question about getting Stellina or eVscope for an astronomy club.

Using filters in amateur astronomy can be confusing, but once you get through some of the basics, they can really enhance your sessions under the stars - either visually or photographically.  In this episode, Tony and Dustin go through filter basics, what they can do for you visually and when imaging, as well as offer advice on which ones to get and why.

We also go over filter wheel options and strategies for using all of this amazing optical gear.

Taking images through your telescope has never been easier.  What used to be complicated, time-consuming and expensive is now accessible to people who've never used a telescope before.  Getting started in taking pictures of the night sky is orders of magnitude simpler than it was decades ago when film reigned supreme.

Now, with modest equipment budding astrophotographers can achieve amazing results right out of the gate, but navigating all that gear can be overwhelming.  In this episode of Space Junk Podcast, we'll explore strategies and gear to get you off to a roaring start taking images that will please your family, friends and all your social media followers.

Building your own observatory is a great way to enhance your enjoyment of getting out under the stars.  Whether it's a simple cover for your tripod-mounted telescope, an easy to build roll off roof on a shed, or a beautiful clam-shell dome with all the bells and whistles, having an observatory can increase the amount of time using your equipment while decreasing your stress level.

In this episode Dustin and Tony discuss all options for creating a personal observatory to house your equipment and offer advice and tips for making your observatory easily and with minimal mistakes.

It's good to be back!  To get things started again, we are talking about the beginning - the beginning of getting started in the hobby of amateur astronomy.  We've also brought some gear to check out.  The links are here:

Welcome to our first segment of Astronomy News from Space Junk Podcast.  The successor to Hubble is finally getting ready for launch.  This month the mission team at Northrop Grumman are putting the final touches on the telescope and testing is almost complete.  Soon, the telescope will be placed on a ship to French Guyana where it will hopefully launch in October.

We've all heard of the Astronomy Picture of the Day from NASA, but there is another website showcasing amazing photos from the amateur community: The Amateur Astronomy Picture of the Day.  Our guests Charles Lillo and Jason Matter tell us the story of how they got AAPOD going and what you can win if you submit your images for consideration!

Automating an observing run is one of the most efficient uses of your equipment.  You can plan the night's observing, then let your equipment do the work!  But what do you need to make this possible?  What can you expect for results?

NASA has always excelled at helping us visualize the Cosmos.  Brian Day works at the Solar System Exploration Research Institute, one of the premier groups at NASA that use data from a variety of space probes, telescopes and observatories from around the world to enable us to explore solar system objects like the Moon, Titan, Mercury and more.

TagBackTV is a popular gaming streamer on YouTube who has incorporated his love of astrophotography into his streams, introducing a new audience to amateur astronomy

What better way to commemorate International Dark Sky Week than by talking with Kelly Beatty, a former editor of Sky and Telescope Magazine and light pollution activist.  He tells us how big an issue our disappearing dark skies are, his thoughts on the new Starlink constellation of satellites from SpaceX and what we can all do to help combat the lightening of our night.

We have limited information about the effects of alcohol in space, but there's no doubt that it is a very important cultural feature for many of us.  Chris Carberry, the CEO of Explore Mars and author of "Alcohol in Space" joins us to talk about the role alcohol can play, if not in space survivability, then at least in coping with space travel.

We also discuss the latest efforts to get to Mars and whether we can get there by the 2030's.

Taking high quality images of our nearest celestial neighbor is harder than you think.  Luckily we've brought Robert Reeves back to our podcast to help you take the best possible images of the moon.  He's also shared a lot of high quality images of his own in the link below:
