Starizona Modular Filter Slider Plate
The Starizona Modular Filter Slider Plate lets you reconfigure your existing Starizona Modular Filter Slider for any optical train by providing a wide range of common astronomy threads. For imagers needing to hit a precise back-focus distance, special thick plates are available that add exactly +3.5mm of optical height.
Reconfigure Your Modular Filter Slider
These plates are designed to give your Modular Filter Slider maximum flexibility. By unscrewing the existing plate with the included Allen wrench, you can swap it for any other plate in the series, whether you need to connect to a camera with M42 threads, a flattener with M48 threads, or a Celestron RASA 8. Because the plates can be used on both the top and bottom of the slider, you can create the exact connection scheme your imaging setup requires.
Add +3.5mm of Back-Focus Spacing
Achieving the correct back-focus is critical for modern optical systems. To help you dial in your spacing, Starizona offers thick female M42, M48, and M54 plates. These plates are identical to their standard counterparts but add an additional +3.5mm of height.
Critical Compatibility: Modular vs. Original Slider
These plates are compatible only with the Starizona Modular Filter Slider and will not fit the older, Original Filter Slider. It is essential to confirm which version you own before purchasing.
-
Modular Filter Slider (Compatible): Both the top and bottom plates are removable, each secured by three screws near the outer edge.
-
Original Filter Slider (Not Compatible): Only one of the plates is removable. If you have this version, these plates will not fit your slider.

How do I know if I have a Starizona Modular Filter Slider?
Check if both the top and bottom plates on your filter slider can be removed. If both plates are attached with three screws each and are interchangeable, you have the Modular Filter Slider and these plates are compatible. If only one plate is removable, you have the Original Filter Slider, which is not compatible with these plates.
What is the purpose of the +3.5mm thick Starizona slider plates?
The thick plates are designed to help you achieve precise back-focus spacing. Many correctors and flatteners require a specific distance to the sensor (often 55mm). Adding a thick plate increases the optical path by +3.5mm, which helps you fine-tune your imaging train spacing.
Can I use two different Starizona Modular Filter Slider Plates on the same slider?
Yes. The plates can be used on both the top and bottom of the Modular Filter Slider. For example, you could use an M48 plate on the telescope side and an M42 plate on the camera side to adapt between different thread standards.
What threads are available for the Starizona Modular Filter Slider Plate?
The plates are available in a variety of common astronomy threads to match your equipment. Options include:
- M42 Male & Female
- M48 Male & Female
- M54 Male
- RASA 8
- C-Mount Male
- Thick (+3.5mm) M42, M48 and M54 Female
I have a Celestron RASA 8. Which Starizona slider plate do I need?
You will need the dedicated RASA 8 plate option, designed to attach the Modular Filter Slider to the RASA 8.
Does the Starizona plate include the screws needed for installation?
Yes, each plate comes with a set of 3 replacement screws and the correct Allen wrench required for installation. You will have everything you need to swap the plate on your Modular Filter Slider.
