It's easy to use up and down, left and right movement allows tracking an object with unprecedented precision using both manual macro adjustments for aiming your telescope and manual micro adjustments for precise observing and tracking. The C-900135TR includes Cassini's sturdy, fully adjustable, pre-assembled metal tripod featuring an accessory tray with slots to place 4 1" eyepieces or lenses and retractable rubber feet. The C-900135TRCFW features a 900mm focal length. The large primary mirror is 135mm in diameter and in mounted in a heavy-duty mirror cell. The finder is Cassini's Mars-Eye Electronic Finder which helps by getting the observer behind the telescope without losing the surrounding field of view when targeting objects. Included with the C-900135TRCFW are a 1" 10mm Plssl eyepiece, a 1" 25mm Eyepiece, and a 2 element 3x Barlow. Youll also get a free Cassini Color Filter. Filtering out certain bands of light can be very useful when observing astronomical objects. With the Cassini Color Filter Wheel, you simply switch eyepieces as you normally would. To switch filters, just rotate the dial on the Cassini Color Filter Wheel. The C.F.W. has three filter settings: Nebula, Planetary and Clear. The Nebular filter is great for filtering out light pollution such as ground light. UHC filters block a large fraction of light pollution and bring out the details of nebulae. The Planetary filter is great for viewing the moon and planets by increasing contrast. 3rd slot is Empty to use additional filter of your choice or left empty so objects can be viewed normally without having to remove the Color Filter Wheel. Additionally, the filters are universal 1.25 threaded filters so you can switch them out with other filters for more usability. Lastly, the Cassini Stellarium CD ROM brings you the skies over your home or anywhere in the world.
