Oh wow, thank you for the offer Andrew. Mine is only around 0.625 and I go with 0.5 on my glasses because 0.75 is unbearable within a minute. For me it presents as 2 distinct vertically shifted images, even with the 0.5 correction. Certainly much more tolerable at high power, but still not as good as it could be for bright stars or thin planet details.
The thought of a quality, flat glass corrector instead of curved plastic does sound very appealing to me.
