The Ultimate Light Gatherers

The Dobsonian telescopes are named after John Dobson, an amateur astronomer who designed a very simple but effective telescope, where the key factor is a large aperture for little money. His idea was to mount a Newton telescope on an easy-to-use alt-azimuth mount that does not need time-consuming alignments.

The Sky-Watcher 10″ Dobsonian is a large aperture Newtonian reflector telescope with f/5 focal ratio, make it ideal for wide field and deep-sky observation. Big aperture means better light gathering power and with this Sky-Watcher Telescope you are able to see prominent deep-sky object such as nebulae, star cluster and many more. It's also an excellent telescope for viewing planets such as Jupiter, Saturn and its rings and more. 

To top it off, the Sky-Watcher Classic 250P Dobsonian is equipped with a 2″ Crayford focuser and focuser locking screw to allow easy use of either eyepiece size.

Tension Control System
The Tension Control System allows you to adjust the friction setting; to increase or reduce the amount of resistance when moving the tube on the wooden mount, so you always have the appropriate resistance. The secret of the design is to correctly balance the optical tube with the specially designed handles (found on the base) and this adds enough friction and tension to allow the tube to move easily when nudged or to stay solidly in position.

Bintel 2 Inch to 1.25 Inch Adapter with T-Thread

Most SBIG filter wheels require a direct connection to an SBIG camera to be operated. Some specialized imaging configurations either require additional filter wheels, or a direct SBIG camera connection is not possible.   In this case, the SBIG USB to Filter Wheel Adapter (USB-FW) can be used to control the wheel.

Note:  The USB-FW does not include mechanical adapters.  If the wheel is not directly coupled to an SBIG camera then custom mechanical adapters may be required.

Features

• USB Mini B interface, 15 foot (4.5 m) USB A to Mini B cable included
• DB-9 style I2C connector for filter wheel – connects to original filter wheel cable
• Universal AC power supply with 9 foot (2.7 m) extension cable and locking power connector included
• Uses ASCOM driver for control from most astronomical imaging software or via custom scripts
• Works with SBIG AFW series filter wheels, FW8S-STXL, FW8S-STT, FW8-8300, and FW7-STX.
• Supports dual wheel operation for the SBIG AFW series wheels

Note:  Older SBIG wheels with a DB-9 style I2C connector may also be compatible, but have not been tested with the USB-FW adapter and correct operation is not guaranteed.

The 1.5-inch diameter Counterweight Shaft Extension Bar (sold separately) is compatible with the following counterweight shafts:

• Paramount MYT Standard Counterweight Shaft
• Paramount MX/MX+ Standard Counterweight Shaft
