Televue 32mm Plossel. Not too expensive - $127 from Bintel.
Great widefield view for an 8inch SCT - the following is a quote from the Bintel Website:
"This one of the Classic eyepieces to own offering improved edge-to-edge sharpness, and a wider and brighter field of view to the standard 25mm eyepiece that comes with most telescopes.. The 18mm of eye relief offers unvignetted viewing for eyeglass wearers. It' s parfocal with the shorter focal length Plossls. The 32mm Plossl, with its larger 50 degree apparent field, will deliver the same true field as the 40mm but with higher magnification."
Have a look at the Televue website - advice on eyepieces for 8inch SCT.
