ERF holder for a large Solar Scope.

Recommended Posts

Graham

Answered a call for help to get an ERF holder made.

 

Took me a couple of days in between jobs at work but this is the resulting monster.

This is being fitted to one mother of a Solar scope.

 

Machined from a solid billet of Aluminium.

 

Front

Access to fit the ERF filter is by removing the 6 countersunk screws and splitting the holder in half.

Back.

The groove is to allow the OTA to locate inside the holder.

It is retained in position by 6 grub screws.

Just to give you an idea of its size.

Beautifully engineered Graham.

 

The ERF must be costing a pretty penny on its own.....
