Barlow 2x-3x Variable Lens

Postby Dr_Reboot on Sat Dec 25, 2004 5:14 am

Has anyone had experience with a Barlow 2x-3x Variable Lens? I'm wondering if this lens' quality and capability is as good as using separate 2x and 3x lenses.
Thanks in advance for any advice!

In theory, this should work just fine. Visually, I can tell little difference between this and two separate Barlows of equal quality.

However, if you are using a refractor or a Mak-SCT, you can get 3x from your 2x barlow anyway just by inserting it forward of your diagonal.
