as John and Tony and a few others watching this thread are saying ( thinking ) save your money and get a few 'wide fields' over time as you can afford them thus building up a set that suit's you and your scope personally ( I see these sets and there is always a gaping hole in focal lenghts
no matter who is selling them .) .
i has taken me over 15 years to build up my Orthoscopics , but the price I have payed for them is under 1/2 of buying them new as a set.
.
They will remain with me forever as the views the give in all my refractors is priceless .
I am 3 years into a TV eyepiece set up as I type this,,,,

Thanks IIS .
