Two key factors that affect your view are seeing and transparency.
Seeing refers to how steady the atmosphere is, while transparency is how clear the sky appears.
Targets at higher altitudes generally enjoy:
- Less atmospheric turbulence, resulting in steadier images.
- Cleaner, drier air layers that improve transparency.
- Better conditions to resolve fine details on planets and deep-sky objects.
So, aiming for higher altitude targets isn’t just about brightness—it’s about getting the sharpest, clearest views possible.
