Re: 2" Diagonal and wide eyepiece - great deal! new [Re: mitaccio]

Wow! That eyepiece is a whopper! Looks pretty cool though.

If it touches near 90, I would just use the filter and slew limits to keep it from hitting. With an alt/az mount, you really want to avoid the area within a few degrees of 90 anyway.

But Ron's rail will take care of the potential interference too. And with that big of an eyepiece, I'm not surprised that you'll need it for balance!

I ordered one of the GSO 2 inch dielectrics on Monday and it arrived today. $100 shipped with 2 day USPS priority was not a bad deal. I'm rather pleased with the build quality and can't wait to give it a try later this week.

This is probably the least expensive option in a dielectric coated 2" diagonal. You want to be sure to get dielectric coatings because they are very hard and resist scratching from repeated cleanings.

Probably the best deal is on the GSO from Agena astro. Keep in mind that Agena includes shipping in the $100 price: http://agenaastro.com/gso-2-90-99-dielectric-sct-mirror-diagonal.html
