There is no eyepiece for your scope that will let you see all of M31.
It
is WAY too large. Don't blame your eyepiece, or the scope. M31 is
HUGE!
It will fill the field of a pair of BINOCULARS!

Right now, you need just to use the eyepieces you have on the objects
you
want to see, and determine where the shortcomings are. THEN you can
decide what eyepieces you need next. But one eyepiece you aren't
going to
find, is one that will show you all of M31 in your scope... But a
32mm
Plossl will still be pretty awesome...

Then what was I seeing, M33 (Pinwheel Gal.)?? If M31 is so big how come
I can't find it with 10" dob?

So that you understand; this galaxy is so huge that it will fill a 4
degree field, if you could see a field that wide with your scope (but you
can't).

Your telescope will show about a fourth of that, depending on what your
widest field eyepiece may deliver...

So you simply can't see it all in one eyepiece field at one time with your
scope. To see all of this galaxy at one time will require a MUCH lower
power, wider field instrument... Or a pair of binoculars...
