I believe this is an Antares diagonal. It works great on my TV 102, but I have 'upgraded' to an Everbrite. That is the only reason for the sale. The mirror does have some tiny sleeks, visible only at oblique angles - they appear to do nothing to affect the fine views that this digonal dishes out. The housing has some minor scratches and minor wear on the barrel. $60.00 shipped within CONUS. Thank you.
