How to use:

Point your Seestar to a bright star in the night sky.
Attach the Bahtinov mask to the Seestar
You should see a 6 star diffraction coming from the star (6 lines of light), the line on the middle will shift position depending on your point of focus, the goal is to align the middle line so that all the lines connect right on the center point where your star is located. Slowly adjust the manual focus setting to achieve an alignment of all the lines.

*TIP: Remember that the ideal focus setting can shift due to changes in temperature. When possible try to acclimate your telescope to outside temperatures before starting your imaging sessions, or refocus thought the night if there are any significant changes in temperature.

※ Every piece is handmade with care, patience, and a lot of attention to quality and detail. We spend extra time on finishing, fit, and the small things that make an item feel considered. Techniques like resin molding, 3D printing, and woodworking can still leave tiny surface variations. Those marks are part of the handmade process—they make each piece unique. They are not treated as defects and are not covered by our warranty.
