Optimized for astrophotography with large dual speed 3″ Linear Bearing Crayford focuser to carry imaging equiment without flexure. It also accepts 2″ and 1.25″ fittings with the supplied reducing adapters (all use non-marring brass compression rings)

Supplied with cast aluminium tube rings (mounting points top and bottom) and V-style dovetail bar. This also allows easy mounting of guide scopes or other equipment atop the main OTA.

OTA weight 13.5kg (15kg inc. tube rings and mounting plate)

Includes 8×50 finder with quick release dovetail.

For improved performance when imaging we recommend the Bintel Coma Corrector and appropriate t-thread spacers (coming soon). The coma corrector will increase the effective focal length by 10% but eliminate the effects of coma seen at such fast f/ratios. Other coma correctors available at Bintel such as the Paracorr Type II and Baader MPCC will also work very well in the 2″ fitting of the focuser.

Bintel BT250mm f/4 Astrograph

250mm mirror diameter with a 1000mm focal length (f/4).

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.
