  • iOptron Stainless Steel Extension Bar for CEM40/50/60/70/etc.

    The iOptron Stainless Steel Extension Bar provides a simple and effective solution for balancing heavy or physically long telescope payloads on compatible iOptron mounts. By increasing the length of the counterweight shaft, this extension bar multiplies the effectiveness of your existing counterweights, allowing you to achieve perfect equilibrium without needing to purchase additional, heavy counterweights. This is a critical accessory for imagers using large refractors, Schmidt-Cassegrains, or heavy camera and guide scope configurations.

    Achieve Critical Balance for Heavy Payloads

    When you mount a large optical tube or a heavy imaging train, achieving proper balance is essential for the tracking accuracy and health of your mount's drive gears. This stainless steel extension bar moves your counterweights further from the mount's axis of rotation, increasing their moment arm. This application of basic physics means a single counterweight can offset a much heavier payload, reducing the total weight your mount has to carry and improving overall stability.

    A More Efficient Balancing Solution for iOptron Mounts

    Instead of stacking multiple counterweights close to the mount, the iOptron Extension Bar creates a more efficient and often lighter setup. This is particularly useful for portable rigs where minimizing total weight is a priority. The bar is machined from stainless steel to match the original counterweight shaft, ensuring a secure, corrosion-resistant connection that threads on seamlessly to mounts like the CEM40, GEM45, CEM60, and CEM70.

    • Reduced Total Mass: By increasing leverage, you can often remove one or more counterweights, lessening the load on the mount's bearings and motors.
    • Clearance for Long OTAs: For long refractors or Newtonian telescopes, moving the counterweights further down the shaft can prevent them from colliding with the tripod legs when pointed near the zenith.
    • Durable Construction: The stainless steel build ensures rigidity and longevity, preventing flexure that could compromise tracking.

  • When do I need the iOptron Extension Bar for my CEM40 mount?

    You need the iOptron Extension Bar when your telescope payload is heavy enough that your counterweights are slid all the way to the end of the standard shaft and you still cannot achieve balance. This often happens when using larger refractors or adding a heavy guide scope and camera to your imaging setup.

    Will adding the iOptron Extension Bar affect my mount's stability?

    While the extension bar is made of rigid stainless steel, adding length to any shaft can potentially introduce a small amount of flexure or increase susceptibility to vibrations from wind. However, this effect is generally negligible compared to the significant benefit of achieving proper balance, which is far more critical for your mount's tracking performance and longevity.

    Can I use this iOptron extension to balance a large SCT on my CEM70?

    Yes, absolutely. A large Schmidt-Cassegrain telescope, especially with a full imaging train attached, is a perfect use case for the iOptron Extension Bar on a CEM70. It allows you to balance the payload with fewer counterweights, keeping the total carried weight lower and putting less strain on the mount.

    How does the iOptron Extension Bar help more than just adding another counterweight?

    Adding another counterweight increases the total mass the mount must move, which can lead to slower response times and more strain on the motors. The extension bar works smarter, not harder, by using leverage. It increases the effectiveness of the weights you already own, allowing you to achieve balance with less overall mass on the mount.

    What iOptron mounts is this Stainless Steel Extension Bar compatible with?

    This extension bar is designed for iOptron mounts that use the standard counterweight shaft thread. This includes popular models such as the CEM40, GEM45, CEM60, and CEM70, among others. It is intended to be a direct fit for these series of mounts.

    Is installation of the iOptron Extension Bar difficult?

    No, installation is very simple. You first remove the toe-saver/end cap from your existing counterweight shaft. Then, you simply thread the extension bar securely onto the end of the shaft. Finally, re-attach the toe-saver to the end of the newly installed extension bar.
