Sorry for my ignorance but what is an “adc” and what does it do for your images?

Nice images 👍

Nice images 👍
adc for "Atmospheric Dispersion Corrector" : it's very convenient to remove interference fringes due to the presence of powermate. The problem is that it also increases the size a little bit ;)
