CatchingPhotons - Basic tutorials for astronomy and astropho

Hi folks!

This YouTube channel provides basic tutorial videos for astronomy and astrophotography. The curriculum will cover topics like
x movement of the stars in the sky
x different mount types
x telescopes to choose from
x image acquisition techniques
x post processing
x ... And much more.
Step by step newcomers are guided through the complex topic of astrophotography.

Hi I'm Chris.
I'm a physicist and very interested and enthusiastic about everything above us. I came across astronomy a short while ago and as i went through all the very good tutorial videos, forum discussions and helping websites, I decided to create a "save haven" for beginners. People without time or with no idea where to start digging may here find their "starting-point" for the long journey of astronomy. This basic tutorials can only scratch the surface but shall cover everything a newcomer needs to know to get started. So join me on my ongoing journey!
Clear skies everyone!
Greetings
Chris


I will link every new tutorial video here in this thread. You can give your comments, ideas, corrections, suggestions, clues or hints... Everything from within this fantastic community is welcomed!

So this is the first part of the first episode of the theory-chapter: "what is there to see in the night sky? - solar system objects"
I will cover the objects, that can be seen in the night sky basically ordering then by distance starting witch the objects inside the solar system.

This is part two of the first episode:

What is there to see in the night sky? - deep sky objects"

Covering stars, nebulas, star clusters and galaxies.

One point of both videos shall be, to get an idea of different objects/sizes and that not every scope can cover every object.

Terms like "length" and "width" will be clarified in the video after the next. (Spiral curriculum.... Yes I'm a teacher ;) ).

A short run through Stellarium. Just the most important points to find your first stars and to get used to the night sky.

RA/DEC? Zenith? Meridian and celestial pole?

Better get this sorted before your first night of astronomy gets started! Here is a quick introduction to the terms and grids and how to find the position of a star just by it's coordinates!

Greetings and merry Christmas!

This video is all about
x Focal length
x aperture
as the two main defining specs of a scope itself. We discuss the resulting aspects of "field of view", "light gathering" and "optical resolution" and why you shall never buy a "300x magnification scope" for 20 bucks.
Hope you enjoy it!

Hey folks!
Last time it was all about focal length and aperture. This time we will bring this two together and discover the F-Ratio.

What does f/8 mean and why can scopes be slow? Check out the latest video of this series.

Clear skies everyone and

Hey folks,

this time we want to open up the telescopes to look what’s inside.
We will discover different types of telescopes – some with lenses, some with mirrors or even some with both of it.
What is an apochromatic Refractor? How does a Newtonian Reflector work? Lets find out!
Clear skies everyone and have fun!
Greetings
Chris

x Why can't we see secondary mirrors?
x What's field curvature / coma aberrations.
x The underlying principles of light paths inside telescope

I did some simulations in 'GeoGebra' to visualize some points.
You find links to my telescope simulations down in the descriptions. Go and play ;-)

Astro-Tutorial #1.9: Telescopes, Eyepieces & Magnification
https://youtu.be/vjf3qEnViVU

Hey folks,

this video will be all about eyepieces and magnification.
We will cover different topics:

* the underlying principles of eyepieces
* the light paths inside eyepieces
* the magnification
* limits of the magnification
* different types of eyepieces

In the end you hopefully will be able to get a first grip on this topic and decide whether an eyepiece is suitable for your telescope or not.

I hope you like the vid, please feel free to leave comments below.

Clear skies everyone!
Greetings
Chris
