1.5x Barlow?

Taking the solar rig out for a spin and to get a perfect FOV of the Sun with my setup I need a 1.5x barlow. I can't seem to find anyone who sells it. I read that removing the lens from a 2x barlow can bring it down to 1.5x but this was not the case when I tried it.

Do they exist?

Barlow magnification cam be adjusted.
Just try to move your camera sensor closer to barlow, if possible.
BTW, I am using tele-converter (2x) instead of barlow, and I can get 3~4x with additional extender rings.
There are 1.4 converter versions, 2x also work if adjusted like I mentioned above (not always possible with DSLR's, as the flange-sensor distance is fixed to 44.5 or 45.5 mm)..

Yeah, the x1.6 Barlow lens is available from the UK.
I’m not home at the moment to confirm supplier, but give me a day or two and I’ll find it.
(I actually have two of them, drop me a PM if interested.)
EDIT
Found it!

Thanks for that.

I tried 1.6x on the astronomy.tools website but its cutting a bit close to the preffered 1.5x I need.

I checked it out. Using one of my solar images it gives a x 1.6 exactly.
Possibly if the housing was moded you might be able to reduce the spacing and get x 1.5
