Ah don’t know what I’ve done here !
But it’s one of those I wish I’d left alone !
I took of the rubber grip to expose the small
screw and loosened it ... now the tilt will go
a long way and won’t stop plus I can’t seem
to be able to relocate the small screw into
any location where it will take hold.

Re: PST Etalon Adjustment PIN
I leave my PST etalon open. No shell nor ribbed rubber band. I use a watchmaker's screwdriver in one of the [screw] drive holes.
Then I can both tune and tilt the etalon ring gently sideways for the most even brightness and surface clarity across the field.
It is probably a bit silly because dust can get inside onto the etalon's outer surface. Though I could use my bulb, dust blower for that.

Rusted,
I do the same thing except I put electrical tape over the holes that do not have the screwdriver in them.

Is this just to avoid tuning off band?Starry Jack wrote: ↑Thu Jun 11, 2020 7:48 pm Rusted,

Or is there some other reason?

Re: PST Etalon Adjustment PIN
The electrical tape is simply to keep dust out of the holes. I meant I do the same thing with no rubber ring and using a small screwdriver as the long lost screw.
