Is the Software Bisque 30 lb counterweight compatible with the Paramount MX+ or MYT?
No. This counterweight has a 1.875-inch bore designed specifically for the Paramount ME II's larger counterweight shaft. The Paramount MX+ and MYT mounts use a smaller 1.5-inch diameter shaft and require counterweights with a matching 1.5-inch bore.
How many 30 lb Paramount ME II counterweights do I need for a 14" SCT with a guidescope?
The number of counterweights depends on the total payload weight. A typical 14" SCT with an imaging train and guidescope can exceed 60 lbs. Since the Paramount ME II ships with two 30 lb weights, you will likely need at least one additional 30 lb counterweight to achieve balance, and possibly a second one depending on the final weight and placement of your equipment.
Can I use this 30 lb counterweight on the optional 1.5-inch shaft for the Paramount ME II?
No. This counterweight's 1.875-inch bore is too large to be safely secured to a 1.5-inch shaft. If you are using the optional 1.5-inch shaft on your ME II, you must use the 20 lb counterweights designed for the Paramount ME or MX series, which have the correct 1.5-inch bore.
Why does the actual weight of the Software Bisque 30 lb counterweight vary?
The weight can vary by approximately +/- 5% due to slight inconsistencies in the density and size of the raw stainless steel blanks used in manufacturing. This is a standard industrial tolerance. The crucial factor for your mount is achieving balance by adjusting the weight's position on the shaft, which easily compensates for these minor variations.
What is the purpose of the larger 1.875" shaft and bore on the Paramount ME II?
The larger diameter 1.875-inch counterweight shaft provides significantly greater rigidity compared to smaller shafts. This minimizes flexure, especially when multiple heavy counterweights are extended far down the shaft to balance a massive payload, contributing to the Paramount ME II's overall stability and tracking accuracy.
My payload is just over 60 lbs. Should I add another 30 lb Paramount ME II counterweight?
Yes. It is always better to have more counterweight mass positioned closer to the mount's axis than to have less weight extended to the very end of the shaft. If your two stock 30 lb counterweights are near the end of the bar, adding a third 30 lb counterweight will allow you to position all three weights higher up, increasing stability and reducing the moment arm.
