Celestron C11XLT
The Celestron C11 offers high light-gathering capability in a rugged aluminum optical tube. With a length of 610 mm and a weight of 12.4 kg, this telescope is still easily transportable to be taken to remote locations and set up by one person. It is an ideal instrument for serious astrophotography.
The 11" SC optical tube provides excellent high-contrast views and can operate at very high magnifications. It features StarBright® XLT optical coatings, which visibly increase contrast and light transmission for brighter, more visible images. shorter exposure times.With StarBright XLT, you will be able to discern fine detail when observing the Moon and planets, as well as faint galaxies and nebulae.
The tube offers an aperture ratio of f/10 with the added versatility of Fastar (see below). You can also pair it with the f/6.3 focal reducer for even more astrophotography options.
The SC 11" optical tube can be mounted on a multitude of mounts thanks to its CGE-style dovetail bar. This flagship optical tube is sure to take your visual or photographic observation to the next level.
Fastar Technology
With Fastar technology, the secondary mirror of the SCT can be removed and replaced with the HyperStar (sold separately) so that a CCD camera can be used in front of the telescope at the f/2 focus of the instrument's primary mirror . The potential of the Fastar system is staggering: exposures are 25 times shorter than if the camera were placed at the native f/10 focus of the instrument. Astrophotographers can capture galaxies and nebulae with exposures as short as 30 seconds.
