Applying a minor tilt to an inline 2" filter????
Here's a challenge to the DIY guys....
How can you apply a small tilt say a few degrees to a standard 2" filter sitting in a 2" extension tube?????
The "conventional" way so far is to cross thread the filter and hope it stays in place!!!
(The reason for the need to tilt? Well, to fine tune the narrow band transmission wavelength. A small tilt moves the centre line towards the blue)
