  • Askar Multifunctional Filter Drawer

    The Askar Multifunctional Filter Drawer is engineered to accept five of the most common filter formats, including both 1.25" and 2" mounted filters, as well as 31mm, 36mm, and 50mm unmounted filters. This integrated five-in-one design eliminates the complex and often confusing task of matching separate adapters and filter holders to your specific camera and telescope.

    A Five-in-One Solution to Adapter Complexity

    For many astrophotographers, especially those new to the hobby, building a compatible imaging train is a significant hurdle. Askar addresses this by integrating the most common telescope-side and camera-side adapters directly into the filter drawer's ecosystem, creating a single, cohesive unit that simplifies connections and removes a major point of failure and frustration.

    Supports 5 Common Filter Formats: From 1.25" to 50mm

    This drawer's primary strength is its ability to accommodate nearly any filter in your collection without requiring you to buy multiple holders. It is designed to work seamlessly with standard 1.25" and 2" mounted filters, and also includes a secure retention system for 31mm, 36mm, and 50mm unmounted filters, giving you the flexibility to invest in cost-effective unmounted glass as your needs evolve.

    Secure Mounting for Both Mounted & Unmounted Filters

    The Askar Multifunctional Filter Drawer ensures every filter is held securely and centered in the optical path. Mounted 1.25" and 2" filters thread directly into the appropriate slider for a rigid connection. For unmounted filters, a machined groove and a dedicated holding ring, fixed by three M2 countersink screws, clamp the filter in place without causing stress or tilt.

  • What makes the Askar Multifunctional Filter Drawer "multifunctional"?

    Its functionality comes from its "five-in-one" design. It is engineered to solve the common problem of adapter and filter incompatibility by supporting the five most common filter types (1.25" mounted, 2" mounted, 31mm unmounted, 36mm unmounted, and 50mm unmounted) and integrating connections for a wide variety of telescopes and astronomy cameras into a single system.

    How do I install an unmounted 36mm filter in this Askar drawer?

    To install an unmounted filter, you first select the appropriate filter slider. You then gently place the 36mm filter into the circular groove on the slider. Place the included filter holding ring over it, and use the M1.27 wrench to tighten the three M2x4 countersink screws, which will securely hold the filter in place without touching the optical surface.

    Will this filter drawer connect to my specific telescope and camera?

    The Askar Multifunctional Filter Drawer is designed to be broadly compatible with "various camera threads" and "various telescope threads." However, because specific adapters are not listed in the box contents, you should verify which adapters are included with the drawer or sold separately to ensure a perfect match for your equipment.

    Is a filter slider included with the Askar Multifunctional Filter Drawer?

    The provided "What's in the Box" list is empty, so we cannot confirm if a filter slider is included with the base product. It is common for filter drawers that support multiple formats to have sliders sold separately. Please check the product options or purchase the specific sliders you need for your filter sizes.

    Can I use 2-inch mounted filters from any brand with this Askar drawer?

    Yes. The drawer is designed to accept any standard 2-inch mounted filter, which uses a universal M48x0.75 thread. You can confidently use filters from any manufacturer as long as they adhere to this common astronomical standard.

    What's the benefit of the Askar filter drawer over a filter wheel on my 8" SCT?

    A filter drawer offers a lighter, more compact, and often more affordable solution compared to an electronic filter wheel. For an 8" SCT setup where back-focus and weight are concerns, the Askar drawer provides a simple, manual way to swap filters. The trade-off is speed; a filter wheel is much faster for cycling through filters, which is a key advantage for automated LRGB or narrowband imaging sequences.
