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." Askar integrates telescope and camera adapters with the drawer: choose the camera adapter that matches your camera's thread and the telescope adapter that matches your telescope.
Is a filter slider included with the Askar Multifunctional Filter Drawer?
Yes. The drawer is a five-in-one system: you choose the filter slider that suits your filter, thread a 1.25" or 2" mounted filter onto it, or secure a 31mm, 36mm or 50mm unmounted filter with the holding ring.
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.
