    Default A 2" 32mm Orion Q70 or 1.25" 27mm Orion EdgeOn Flat Field for my low mag on a 8" dob?



    Just wondering for a low powered magnification wide field view. The focal length is 1200mm on the Orion XT8. I'll be getting 3 decent eyepieces for my first dobsonian. So, which would you choose? Or do you have a better choice?

    Orion Telescopes: 32mm Orion Q70 Wide-Field Telescope Eyepiece

    or

    Orion Telescopes: 27mm Orion Edge-On Flat Field Eyepiece

    That's a tough one-- for a wide field the edge on is about 50 degrees vs the 70 degrees of the Q70 --- but the edge on has very good reviews!

    Both are fine eyepieces. But using my rule that above 26mm go with a 2 inch if you have a 2 inch focuser-- then I would pick the Q70 for my wide field low power eyepiece.

    Here is an AstroMart review of the Q70-

    The 30mm also has good reviews.

    2" low power eyepieces are awesome!

    I love the views with the Q70 32MM and I think it goes great with the XT8. I do have to "pull" it out about a .25" on the focusing tube so I dont have to turn the focus knob so far out for focusing. It is the first eyepiece I put in when viewing DSOs. My family loves the way Orion looks when viewed through it.

    You might be able to pick up a used Baader Aspheric 31mm for only a little bit more money. They have been getting very good reviews. New they sell for $189, but used I have seen them go for about $140.
