PrimaLuceLab PLUS 10mm Spacers

Their primary function is to add 10mm of height or separation between two mechanical components in the PrimaLuceLab PLUS system. This is crucial for preventing physical interference between items like a guide scope and a main scope's focuser, or a camera body and a dovetail clamp.

You may need these spacers if you find that components in your imaging train are too close together. For instance, if your guide camera housing touches your primary focuser when you try to achieve balance, or if a filter wheel cannot rotate freely because it hits a dovetail clamp, adding these spacers between the tube rings and the dovetail plate can resolve the issue.

While designed for the PrimaLuceLab PLUS ecosystem, they can potentially be used with other hardware that uses 20mm or 55mm hole spacing and M6 screws. However, perfect compatibility and alignment are only guaranteed within the PLUS system.

The spacers are designed to be used with M6 screws. Because they add 10mm of thickness, you must use M6 screws that are correspondingly longer than the ones you would use without the spacers. For example, if your original connection used a 10mm long screw, you will now need a 20mm long screw.

Yes, this is a perfect use case. By placing the PrimaLuceLab PLUS 10mm Spacers between your main telescope's tube rings and the dovetail plate they are mounted on, you will raise the entire telescope by 10mm. This often provides enough clearance to solve interference problems with a parallel-mounted guide scope.

Yes, you can stack spacers to achieve greater separation. If you stack two spacers for 20mm of clearance, remember that you will need M6 screws that are 20mm longer than your originals to ensure a secure connection through both spacers and into the threaded component.
