I've uploaded 4 speeches from recent ASV monthly meetings to youtube. The meetings are open to the general public and the dates are published on the
ASV website. If you can't make it to the meeting you can now watch them on youtube on this page:

The topics are many and varied - so far we have speeches on big data, observing obscure deep sky objects, astrophotography and Cosmology.
