What's in the Kit
1x Bahtinov Focus Mask Verify and fine-tune focus in seconds. The diffraction pattern makes it easy to reach pin-sharp stars, and the magnetic mount lets you attach and remove the mask without shifting the telescope.
1x LensGûard Magnetic Dust Cover A snap-on cap that protects both the main lens and the wide-angle camera. Its microfiber lining traps fine dust, and it can stay on while the telescope closes, keeping the optics covered during storage and transport.
1x DeWiew Protect & Filter System A collapsible conical dew shield for the main lens combined with a 2" filter holder and an integrated wide-angle camera hood:
Dew & stray light control: the 10° conical geometry reduces condensation and blocks peripheral ambient light.
Wide-angle camera hood: limits side light on the wide camera for better contrast in wide-field images.
2" filter holder: accepts standard 2" (M48 x 0.75) filters, including UV/IR cut, neutral density and color filters.
Full aperture preserved: no intrusion into the main lens aperture, so no vignetting.
Safe Power Off System: includes the components that keep the accessory secure during the telescope's automatic homing.
Why Choose the Kit
One purchase, complete setup: focus, protection and filtering covered in a single order.
Designed to work together: all three accessories use the same self-aligning magnetic system.
Lightweight and portable: the collapsible dew shield and compact parts fit easily in your bag.
Important Note: The kit includes the Bahtinov Focus Mask, the LensGûard Dust Cover and the DeWiew Protect & Filter system. The Seestar telescope and optical filters are not included.
