Barlow x 3 on eBay

[ChrisSnape]

Hi Folks,

Am I right in thinking that this type of Barlow lens won't affect the back focus of my little scope? Tried a standard one but it pushed the focus too far forward (got it refunded). But I assume this one won't affect the length of the focuser?

Compact Barlow lens, 3x magnification, 30x1mm fitting on eBay (end time 23-May-11 01:33:18 BST)

Cheers for any feedback.

i think you are correct. I have a 1.6x lens that looks similar, came with my binoviwers.

Quality may be ave, but worth a go!

Never seen one before. I'd be very interested in how it performs.
