I am hoping to understand more about refractors.Or if someone can shed some light, on this for me.Whats the differance in a triplet and a doublet?I know a triplet has three lens,and a doublet two. But is one better than the other, for overall viewing. So, if one had a 102 ancro and a 102 apo set up side by side.Besides the false color in the ancro., what are the pros and cons for a apo, and for a doublet and a trplet. Sorry for asking but some how i got confused. Thanks to everyone for taking the time to explain this to me.
There's a good online article about refractor designs, Mark. I hope you find it useful.
