Advantage of aperture (?)
I consider myself newish to astrophotography, I’ve been imaging for nearly a year, I started with a ZS71 and graduated quite a while ago to a 115 triplet refractor.
In spite of my online investigations, I have yet to fully understand the advantage of moving to a larger aperture telescope, particularly if I keep the f ratio the same.
As an example, I see that I can buy an 200mm f/8 RC with a reducer that gives me the same f/5 that I have with my current 115 refractor with a reducer flattener.
What practical advantage will this give me if I keep my same camera (asi294mc)?
Thoughts and images especially welcome.
