TS Optics 2" Helical Focuser and 2" Variable Extension with Locking Screw for Precise Focusing
For example, in photography and lunar and planetary observation; at the same time, 2" variable extension from 67mm to 100mm - as you rotate, the eyepiece/camera rotates with it!

♦ Perfect for adjusting distances
♦ An ideal 2" variable extension
♦ Photography of the moon and planets, but also deep sky with sensitive focus
