Bintel BT302-B 12" Dobsonian

This BINTEL telescope has an expertly figured and polished parabolic primary mirror made from BK-7 glass. It's guaranteed to be diffraction-limited, meeting the theoretical limits of resolution for its size. The mirror is mounted in an aluminium cell that allows rapid equilibrium of the mirror to the outdoor temperature.
Bintel's Dobsonians now include knurled collimation knobs on the primary mirror cell making precise optical alignment much easier - no more fumbling with tools in the dark. A cooling fan is included to achieve faster cooldown. The secondary mirror is held in a fully adjustable four-vane spider. BINTEL Premium Dobsonians are equipped with a 2" 10:1 Fine focus Crayford focuser for precise focusing even at high powers.

The new brake system makes the Dobsonian easier to balance and easier to use. The brake mechanism can be positioned and set at the exact balance point of the telescope tube. The large aluminium knob can then be tensioned to the perfect level for smooth movement of the telescope. If heavy eyepieces are being used it is easy to apply a little more tension. If you prefer light, easy movement you can back the brake off.

Every Bintel Telescope has been given a full checkup prior to sale. The Optical Tube Assembly is thoroughly checked and collimated to ensure your new telescope is going to perform as you would expect.

Not only can we supply an excellent telescope at a fantastic price, we offer the after service support to ensure years of happy observing. You can shop with confidence at Bintel!
