طقم ترقية المحاذاة القطبية لـ RST-135

Installed this on my RST-135 and the new base makes drift alignment much more intuitive. It feels solid and I got a sharper polar scope view on first try. Saves me time setting up in the field.

I was skeptical at first, but the base is machined so precisely that polar alignment now holds rock-solid even after a full night of imaging. It saved me the headache of shipping the whole mount back for the upgrade.

I was a bit worried about the installation process, but swapping the old base for this one was surprisingly straightforward. The integrated wedge feels much more precise, making fine-tuning the polar alignment a lot less frustrating and saving me from shipping costs on the full mount.
