Hi folks! I know it’s been awhile since I’ve been on here. Back to work full time… for awhile anyway. However I had a chance to do a presentation on amateur spectroscopy for the Astro imaging channel (also known as TAIC) on Youtube this past Sunday.
You can see the presentation in its entirety right here: https://www.youtube.com/watch?v=e3wZos5CMC0
Hope you enjoy it!
As always, thanks for reading!
