Hi all, I was wondering if anyone has already pointed out or have been dealing with this optic's AliExpress seller. Some items caught my attention, for example there is a double air-spaced refractor objective D90-f5.5 for about 77$ but I'm not an expert and i'm only thinking about a possible DIY Very Low Cost refractor for EAA. The mirrors are not advisable because they are only spherical, not parabolic. Kind regards
