COMMENTS:
We've reviewed several wide-view 2-inch EP's over the years and especially for the price this one simply amazed us.
Field correction is good though edge performance does begin to soften very slightly with short focal ratio telescopes less than F/6. With our SkyWatcher ED100 the view and field correction was astounding as was the view in an 8-inch Schmidt-Cassegrain and our 7-inch MAK.
Even with a 10-inch f/5 Newtonian, stars appeared tack sharp far from the optical centre of axis - far better than many more expensive brands we've come across.
