iOptron Dovetail Plate - 178mm universal
- 178mm (7-inch) Length
- Universal Mounting Design
- Provides Secure OTA-to-Mount Connection
- Aids in Balancing Telescope Assemblies
This universal dovetail plate provides a rigid 178mm mounting platform, essential for securely attaching your optical tube assembly (OTA) to a compatible astronomical mount and achieving precise balance.
The 178mm length offers ample surface area for attaching telescope tube rings, providing a stable and secure connection to your mount's saddle. This length is particularly effective for balancing short-tube refractors, smaller SCTs, or Maksutov-Cassegrains, especially when imaging accessories like cameras or heavy eyepieces are added to the optical train.
Designed to be "universal," this plate typically features a combination of mounting holes and slots to accommodate a wide variety of tube ring spacings from different manufacturers. This adaptability makes it a reliable choice for various optical tubes, preventing the need to find a proprietary, instrument-specific plate.
The primary purpose of this 178mm plate is to create a secure, standardized connection between your telescope's optical tube (via tube rings) and your astronomical mount's saddle plate. Its length also provides the necessary travel to slide the telescope back and forth for precise balancing.
Yes, a 178mm plate is a good length for balancing an 8" Schmidt-Cassegrain Telescope (SCT). When you add a camera, filter wheel, or heavy eyepiece, the center of balance shifts. This plate provides enough length to slide the telescope forward or backward in the mount saddle to compensate for that extra weight and achieve proper balance on both axes.
"Universal" means the plate is designed with multiple slots and pre-drilled holes to fit a wide range of telescope tube rings and accessories, rather than being custom-made for a single telescope model. This increases its compatibility with equipment from various manufacturers, though you will need to supply your own mounting bolts.
A 178mm (approximately 7-inch) plate is ideal for short-to-medium length optical tubes, such as small refractors, 6"-8" SCTs, and most Maksutov-Cassegrains. It should be long enough to span the distance between your tube rings comfortably while leaving extra room at the front and back for balance adjustments.
Yes, in many cases. If the plate has appropriately spaced and threaded holes, you can often mount a set of guide scope rings directly on top of it. This creates a rigid, piggyback guiding setup, which is a common application for plates of this length.
The product title does not specify the dovetail style (e.g., Vixen V-style or Losmandy D-style). You must visually confirm the plate's width and angled profile to ensure it matches your mount's saddle. Vixen-style is the most common standard for mounts in the light-to-medium duty payload class.
