Barlow 2x or not?
I have been out of the hobby for some time and recently began to re-ignite my interest.
Many moons ago (pardon the pun,) I bought a Meade 2x Barlow to allow me flexibility with the other EPs that I bought. There has been rumours that if the Barlow is inserted into the scope first (I have an LX90) then the power is greater than 2x. Some suggest that it is then 3x.
Anyone there with sufficient knowledge to definitively inform me whether inseting the Barlow first will actually increase the power of the selected EP and if it does, by what factor?
