Hi,

What is the difference between having such a small diameter (100mm) on the refractor vs the (250mm) diameter on the reflector? The smaller of the 2 is $400 more than the 250mm. Why is this? Is it better? Are they both as good as each other on a NEQ6 mount? Which ones is better for astrophotography?

That was a lot of questions but if you could answer any that would be helpful!

Regards Nick!

+I would primarily use the scope for astrophotography.
