A practical benefit of this is that prior to guiding, you can insert an eyepiece into the guide scope and easily align the guide scope with your main imaging telescope.

Then remove the eyepiece and attach your autoguider camera

The fixed-orientation focuser mechanism will not rotate inserted autoguider cameras or eyepieces when focus adjustments are made.

The helical focuser simply moves the attached device inwards or outwards while maintaining its orientation.

This convenient feature means your field of potential guide stars will not rotate as focus is adjusted, further increasing ease of use
