Following an analysis of the charts provided on UHTC by Meade and a lot of number crunching here are my reults: An LX-90 with UHTC has a transmission percentage of 77% (includes 13.69% by area central obstruction). An LX-90 with standard coatings rates at 65.7%. The improvement between the standard coated scope and the UHTC coated model is 17.4%

The UHTC LX-90 shows about a 5.5% improvement over a Nexstar 8.
