barlow lens

[bruno]

Could anyone tell me if you can get a barlow lens with T ring thread other than 2x, have had a look on the net but it only can find 2x thanks

yes there are a few that have a thread to mount to a T ring
some you have to remove a cover to get to the threaded part like this one

There will be others but one of the best is TeleVue, you need deep pockets but they produce Powermates in 2x and 4x with matching T adapters

When you say other than 2x, which way are you looking to go? less than 2 or greater than 2?

One of these would let you use all manner of barlows

sorry for the late reply, but yes I wanted something like 3x or 4x i have found a few of the 3x  just wondered ifthey do bigger ones but now i have seen the item what M37  has posted  i will get one of those aswell because i was reading something that was saying that if you put your barlow between the extension and the scope it increases the magnifcation by 0.75 ie 2x = 2.75 can only try it and see thanks forthe replies
