Splitting hairs.....
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. Related but distinct subjects like physical cosmology, which studies the Universe as a whole
There are astronomers in the group but they are into deep field astronomy (Ha/filtered spectrum, telescope mounted, long exposure/ EQ mounts, cooled sensors). This lens would mostly suit astro-landscapers to include earthly foreground elements for context and relatable interest.
Then again, the first thing that everyone does with a big white is shoot the moon
