it seems to me that in this forum televue low power eyepieces agree with every one ,and the type of tele vue chosen is largely a personal choice(BIT LIKE PICKING A SPORTS CAR) I was hopeing that other brands of eyepieces may have been nominated by experienced users and i invite those commentators to express their point of view as it may generate more knowledge and information for end users like myself, before this thread is dead buried and creamated thanks all

FYI the difference in FOV between the NAG31 and the ETH21 is 21%, which is not inconsequential.
At a dark site, where else for a 25" scope even old eyes can get to 6mm eye pupil, so a NAG31 is not out of the question, the power is lower and the FOV is broader so that the observer can see 46% more sky.
