Another item you may wish to cover is external galaxies that are easily visible in 7x50 binoculars. For southern (dark) skies I would rate these as Centaurus A, M87, NGC253.
Thanks for your input.

I'll add a mention about internal focusing on the "more expensive binoculars" slide. I think you've been lucky to find any at $24!!! (I'll mention them alongside waterproofing and nitrogen purging)

I'll add a slide for objects I haven't created virtual views for, and include those 3 galaxies.
