Hi everyone-I'm new on this site.
Have just purchased Long Perng 90mm, and am reasonably happy with it. I haven't done a lot with it as yet, but bright deep sky stuff is impressive-but I have a feeling it is a bit soft on planetary observing. I'll reserve judgement until I have used it under better conditions.
Luke at Andrews was unsure of the glass used, so I contacted the factory, and they say it is FPL51. Colour correction seems pretty good though
