I need help deciding on what diagonal to purchase for my AT102ED. I was initially inclined to purchase the AT 2" but it is currently unavailable and I need to get this scope fully operational. My premium eyepieces are 1.25", the widest being a ES 24/68* which should theoretically give me around 2.25*, more that enough to view many of the nebulas I plan on looking at. My 2" eyepieces are mostly my finders for my 8" Zhumell Z8 (30 mm GSO superview and 38 mm Agena SWA). After the purchase of this refractor I am not planning on spending much more for a long time until I get a lot of observation time and can appreciate this setup fully.
I have decided that my options are either a premium 1.25" such as TeleVue Everbrite or the 2" Orion Dielectric Diagonal. The difference of $60 is not a big deal to me.
I like the idea of the TeleVue being the last 1.25" diagonal I will ever need to buy and own. It has a solid construction that will accept the heavier 1.25" eyepieces, holds its value, and has excellent optics.
The Orion 2" will accept my 2" SWA but that really is the only immediate benefit I will reap. I chose the Orion based on looking very similar to the AstroTech.
I considered GSO and its clones but the 1.25" adapter is machined in a way with a dish that will not allow my larger 1.25" eyepieces to sit flush and I have concerns about how secure it will hold them.
Currently I am steering towards the TeleVue based on my current setup. I would like to get some other opinions.
Thank you and clear skies.
