It does absolutely nothing that cannot be done at least as well and in most cases a whole lot better by a 40mm eyepiece in a 2" barrel.
One thing I can tell you is this. On the basis that the only telescope Danial owns is an 8"/f6 dob on an undriven mount, without setting circles of any kind and that he doesn't have any other eyepieces having a focal length > 25mm; the last eyepiece he needs is a 40mm 1.25" plossl. It does very little he can't do with a 32mm plossl. On the other hand he will find a 2" 40mm eyepiece quite useful as a low power finder eyepiece and for widefield views of those extended objects you are getting a restricted field view of.
I own a full set of high grade orthos btw but I don't use them for low power views of extended objects. I do use them for high power views of galaxies and other extended objects.
