About this product

The Askar 5 in 1 -  M54 Filter Drawer is a very versatile answer to the difficulties in adapting to the use of different filter and thread sizes that are typical in Astrophotography.

This multi functional filter drawer can accommodate both mounted filters (1.25"/2") and unmounted filters (31mm/36mm/50mm) as well as connect both camera side and telescope side with either M42 (T2)/M48 and M54 threaded adaptors.

Assembly Steps:

Users have to follow the below steps to successfully assemble the Askar filter drawer and assemble it into the optical path of your optical system.

• Remove the main body of Askar filter drawer
• Choose the correct camera adapter matching the thread type of your astronomy camera
• Fix the camera adapter on to the main body with the included 5 x M3×8 countersink screws and M2 wrench
• Choose the correct telescope adapter matching the thread type of your telescope
• Thread on the telescope adapter
• Connect the filter drawer and your telescope
• Connect your astronomy camera and the filter drawer
• Make sure that these accessories are tightly connected and the whole system has the correct back focus. You can add extra spacers to reach the required back focus
• Choose the correct filter slider according to the filter size you are going to use. If choosing a 1.25" or 2" mounted filter, directly thread it onto the filter slider. And if choosing a 31mm, 36mm or 50mm unmounted filter, gently put the filter into the circular groove and superimpose the filter holding ring, fix the holding ring with the 3 x M2×4 countersink screws and the M1.27 wrench  to securely hold the filter.
