Portland Alt-Az Workshop 2022 YouTube videos are available

Hi everyone,

Zane Landers was kind enough to split out the individual presentations from the YouTube live streams, making it much easier to view each presentation. Thank you Zane! These videos can be seen here:

With the exception of my faux pas (forgetting to start the recording for the day 1 afternoon session until Richard was well into his presentation) everything worked really well for our first hybrid workshop. I think everyone involved agrees that this is the way to go in the future because it makes the workshop so much more accessible.

A quick shout out to all the presenters - beyond the high quality of everyone's talks is their willingness to share. There was no "secret sauce" being held back, and everyone's genuine willingness to discuss any detail of their project shows that the spirit of amateur telescope making and astronomy is alive and well. My personal thanks to you all for making this year's Alt-Az Workshop a huge success.

Howard
