I have had the Orion ST80 80mm Refractor Telescope for a while now, but I eventually want to upgrade to a better one. When I look at the refractor telescopes on optcorp.com, most of the ones for astrophotography are by William Optics. The point is that you only get 61mm of aperture on the WO for $590, and 80mm on the Orion ST80 for only $130?
What I am not understanding is why the WO is more expensive than the other one considering it only has 61mm vs 80mm? Although, I have heard it has better quality lenses.
My main question is, is it worth it to upgrade to a WO for astrophotography that is only 61mm from my 80mm Orion ST80? And what some differences between them that make them so different? I also don't think spending $1010 on an 81mm WO is a very good option, that is, unless a see a more valuable reason.
