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.

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.
