Illuminated part for eyeiece or 9x50 finderscope

When taking long exposure astrophotos guiding the telescope is unavoidable. The cheapest solution can be this 12.5mm guiding eyepiece. Place the eyepiece into a guiding scope mounted paralelly with the main telescope and find a bright star and place it into the center of the view.

When using a GoTo mountand high precision alignment is needed this eyepiece might also help a lot, making it possible to center the alignment star precisely to the center of the view. If the magnification provided by this 12.5mm eyepiece is insufficient a 2x or 3x Barlow can help to achieve higher magnifications. The reticle can also be focused and illumination brightness is also adjustable.

The 23mm Illuminated eyepiece is intented to use mainly for finder scopes.
