STEP 1 - PREPARATION

Firstly, place the filter on a lint-free piece of paper or cloth, being careful not to drag the filter across the surface - this could scratch the delicate coating.

STEP 2 - FILTER ORIENTATION

Determine the correct orientation of the filters. For narrowband filters, use a screwdriver or a pen to check which side reflects multiple images - this the camera-facing side.

For LRGB, shine a torch through the filter, looking for the side which shows concentric circles around the perimeter - this side should face the camera.

STEP 3 - ATTACH THE MASK

Place the filter mask on filter and gently clip it on. The tolerances are very tight, so do not apply too much pressure.

STEP 4 - FILTER PLACEMENT

Move the filter over to the filter wheel, being careful not to drop it. It's a good idea to carry it over a piece of paper or cloth just to be safe.





STEP 5 - SCREW IN THE MASK

Screw the filter mask in place, making sure you do not over tighten the screws. All it needs to do is keep the filter held in place so it doesn't move around.

STEP 6 - REPEAT

Repeat the procedure for each filter. It's worth noting down which filter is installed in each slot so you can tell your software later.
