Hey Jen, great pics! Having seen at least one yourself, it probably doesn't surprise you that eclipse buffs never get sick of looking at eclipse pics
The last one is particularly cool with the inner corona and chromosphere/proms.
Re stacking - have you shot these in RAW? You could try and tease out more detail if you have - useful if you want to show as many aspects of it as possible in a single shot. Not that there is any need with these photos though
