This is a year old sparsely used Skywatcher 120mm F5 refractor with reduced (but still present due to its fast F ratio) chroma - the scope got an aftermarket professional lens coating by Sirius Optics. This service is not offered by S.O. anymore. The coating is of the CASS variety - this is basically a minus violet filter with additional tweaking of the spectral characteristics to get a more pleasant view. I was able to push the scope to 180x on the Moon and 150x on Jupiter w/o image deterioration (with Planetary Contrast filter on). This is mainly a low and medium power scope for browsing the deep sky objects.
I planned to fix it on the Nexstar-4 mount to serve as a vacation scope but it is too much for that mount. $299 and $16 shipping CONUS.
