ZWO M42-M48 extender (16.5mm)

ZWO EFW 8 x 1.25"(31mm)

ZWO 1.25" New Narrowband SII filter 7nm

Optolong S-II Narrowband (6.5nm) Filter - 2"

The Optolong IR Pass 685nm Filter blocks wavelengths below 670nm to enhance contrast and surface detail and reduce the effects of seeing when used in IR-LRGB imaging of the moon and planets. Atmospheric seeing and distortion diminish as you move further away from visible light into the infrared, and since CCD and CMOS sensors are sensitive to IR light, imaging in the infrared will improve your results.

กล้องดูดาว Sky-Watcher Star Discovery P150 6" f/5 Reflector SynScan WiFi Goto Telescope

This versatile Newtonian reflecting telescope provides both beginners and more experienced amateur astronomers plenty of light and high stability for a very modest price. It collects so much light with its generous 150mm diameter that distant DSOs such as the Ring Nebula in Lyra or the Dumbbell Nebula become beautifully visible and globular clusters, such as M13, resolve into a multitude of individual stars at their edges. Planetary observing provides rich detail in images of Saturn, Jupiter, Venus and Mars.

Askar Backfocus Adjuster M54(F) to M48(M) with variable 16mm-20mm extension

The M48 backfocus adjuster's front telescope interface is female thread M54x0.75 and the rear camera interface is male thread M48x0.75 (Please note that it is NOT M48 on both sides). The overall thickness is 18mm and it offers ± 2mm of adjustment range.

The backfocus adjuster is CNC machined. Each unit is a 0.05mm precision adjustment, and the surface is printed with a scale for easy adjustment and to save the position. There are two holes for fixing screws, which make the adjuster easy to use with different products.

By rotating the backfocus adjuster, it can be adjusted between ±2mm to match the backfocus requirement, and to solve the various imaging problems caused by the backfocus.
