About LinkBacksI am thinking about getting a 2" GSO eyepiece for some wide field bright views, maybe a 42mm. As i live in a light polluted area i'm hoping this will give me enough light to see some messier objects. I have seen the Orion nebula through 1.25" 25mm and 10mm eyepieces, the view was clear but quite small. Will the 42mm not give enough magnification to see messier objects? Or will i see more?

I think that will be a fine eyepiece for wide angle viewing. The EP I use most often in my 8" scope is my 27mm. It gives me about the same magnification as the 42mm will give in yours, so the brightness level will be comparable too. I can see even small objects like M57 with it. Best of all, I can see dim objects pretty well on a dark night.
You will find it extremely useful for finding faint objects. Once you have found them, you can always step up the magnification to see more detail.

i have pretty much the same ep,mine is
a gso superview with a 68* fov.
i also have an 8"s/w dob.
i love the ep for what it gives,wide field views.
it works pretty well in my scope,with my eyes.
they perform better than the price suggests.
if you get one,you won't be disappointed imo.
clear skies,

Same here-- I also own the 2 inch GSO Superview. It gets a lot of use on extended Messier objects like M45, and to locate dim objects.

Since you observe from a highly light polluted area, beware that the 42mm eyepiece will accentuate the sky glow as much as your intended targets.
