 Greetings and welcome to the introduction to astronomy. In this video I am going to start kind of a conclusion of what I started several months ago with these videos that were done and summarize what would be coming next. So what's going on? Well, we've done lecture slides and videos that are available for the OpenStacks Astronomy second edition textbooks. You will find a total of 106 lecture videos that have been uploaded and they will be updated periodically or as needed. So as there are new discoveries where there is a good reason to go and redo a video, I will look at redoing videos and re-recording those. All the materials I do are released under a CCBY license so you are welcome to use and or adapt the files all you want to adjust if you are using them for your own classes. You can do that as long as you leave the attribution as to the original creator of the work. And I provide within the description, there is a Google Drive link to the access the lecture slides. They are available in PowerPoint, Apple Keynote as well as a printable PDF format for you to be able to review and or use and those are openly available as well. They are also released under the same license. I plan on continuing to update the channel and what I'm looking at over the coming months is to post new videos on Monday, Wednesday and Friday. On Mondays, I do the astronomy picture of the day. I do that, use that for my classes as a point of discussion. So I do this on a separate channel but I will be posting the Monday picture here as well. So that will be my Monday video that I will do. And I will give a short discussion of that about three to five minutes and I use this for my astronomy classes. On Wednesday and Friday I'm still a little open as to exactly what I'm doing here because I am recording this several months in advance of when it will be released. But I'm looking at doing some short special topics videos that I will work on over the coming months and will upload those on Wednesday and Friday. The exact details of those I'm not exactly sure how I'm going to do that yet. But I'm looking at doing some short special topics, maybe again a three to five minute video on specific topics in astronomy. So I hope that these videos have been useful and I hope that the future ones coming up will be useful for you as well. So that concludes this video on the conclusion of at least the initial portion of our assignments videos we're uploading here. I'll be back again with more topics in astronomy. So until then have a great day everyone and I will see you in class.
