To keep the lens from getting damaged
The Hubble Space Telescope is a reflector, so its objective is not a big-moose lens at the front;it's a big mirror in the back.The diameter of the objective mirror is 2.4 meters(7.87 feet), (94.5 inches).
It does not have a magnification properly speaking since it works as a camera, not a visual telescope. The aperture of the Cassegrain-Schmidt mirror is 2.4 m. The main camera has 16 MB.
HST is a Cassegrain reflecting telescope using the Ritchey–Chrétien design, with an aperture of 7.9' (2.4m). It has observational ability in the Ultraviolet, Infrared, and Visible light spectrums.
The Hubble Space Telescope has a segmented mirror made up of smaller hexagonal mirror segments that work together to form a single large mirror. This segmented design allows for a larger aperture size than a single-piece mirror of the same size and also allows for easier maintenance and replacement of individual segments if needed.
The Hubble Telescope was named after its designer Edwin Hubble.
The orbiting vehicle measures 13.3 by 4.3 m, the aperture diameter is 2.4 m.
An aperture door is a type of door that features a small opening or "aperture" within its structure, allowing for visibility or passage of light while maintaining privacy or security. These doors are often used in settings like hospitals, laboratories, or secure facilities where access can be controlled. The design can vary, with some featuring sliding panels or flaps that can be opened or closed as needed.

a hatch is a small opening in a door or cover.
snot an easy one is it

Yes, It will cover your garage door, but will not cover your friends vehicle.
Yes, the Toyota Highlander comes with a sliding side door. Also the sliding door is power operated. It has a wide aperture to allow multiple people through the door at once as well.
When needing a dog door cover replacement, follow these steps: Measure the dimensions of the existing dog door cover. Purchase a replacement cover that matches these dimensions. Remove the old cover by unscrewing or unclipping it from the door. Install the new cover by attaching it securely to the door using screws or clips. Test the new cover to ensure it fits properly and functions correctly.
An aperture membrane is a section of enzine forming the base of an aperture.
just cut the rubber (glue) around that cover do you mean theguide rail lock cover? if so... working at the rear edge of door remove two screws that secure it to the door and manipulate it out of the hole.
