Nebulae were to be drawn by hand by a visual observer using a precision bifilar micrometer (photographing them was impossible with the very slow emulsions of the 1860s), but the secondary mirror cell could be swapped out for a camera to allow photography of bright objects at prime focus.
Tenders are invited for furnish the university with a custom fabricated 6.5-meter telescope mirror cell for the telescope san pedro matir project.
* The modular design permits each gimbal mirror cell to be modified or replaced with different shaped cells to accommodate sensors or other asymmetrically shaped payloads.
To balance it I had to strip everything from the top end (I just have a red dot finder, no optical finder) and fit a 9kg weight to the mirror cell. The philosophy that I kept in mind throughout my calculations for the 600mm was that if I had to add weight anywhere it would be at the top end rather than the bottom.
The right side of Table 1 also indicates normalized values of [J.sub.sc], conversion efficiency, and absorption ([lambda] = 600 nm, rest of the reflected light) of the textured cells with respect to those of the mirror cell. The table clearly shows that the cell textured for 30 seconds has the highest efficiency.
The cast-aluminum primary mirror cell broke, the secondary mirror spider got severely bent, and all the external accessories, except the focuser, were sheared off the tube and damaged.
Brent took the primary mirror, mirror cell, and spider assembly from the old scope and integrated them into the wood OTA.
He included an aluminum plate on the bottom (to support the mirror cell), and plywood ring on top for attaching the truss poles.
At the mirror-cell end, the threaded rod is fitted with a spherical ball-rod end, which mates to a pin in the outer circumference of the mirror cell's outer ring.
