Its about 10-15% extra transmission according to the Meade curves. Also the curve is much flatter around the 90% mark for the UHTC's and for the EMC's it rounds of at the lower and higher wavelengths to around 75% peaking at 80% in the middle.
One strange thing I have noted is that OTA's that say EMC on the side seem to have a Ultra High Contrast label on the front. IS this the same with UHTC's?
Chris, it boils down to budget and I believe I am getting a bargain with the accessories being thrown in. This is only my first platform for a more portable goto telescope.
I have not had much luck finding user reports and comparisons on the issue. The One thread i found on CN indicates that its not a huge difference.
