TS T2 M42x0.75 extension tube - 10 mm length - with T2 threads at both ends.

♦ Optical length: 10 mm

♦ Male thread length: 4 mm

♦ Female thread length: 9 mm

This low profile adaptor enables the connection of T2 accessories to adaptors with M48x0,75 male thread.

• Thread towards telescope: M48x0,75 - 2" filter thread (female thread)
• Thread towards camera: T2 - M42x0,75 male thread
• Optical length only 3,5 mm
• Combining the optical extension tube TSVF230 with the TSM48-T2 adaptor provides a Focal Adaptor from 2" to T2 - with no optical length!

Collimating your refractor telescope is quick and easy when you use this 1.25" Cheshire collimating eyepiece. You see in seconds the collimating situation of the telescope, you also can use the Cheshire on newtonian telescopes.

The adapter extends a male T2 thread to M48x0.75 (2") filter thread without increasing the length.

• Female thread: T2 - M42x0.75
• Male thread: 2" filter thread - M48x0.75
• Length: only 2.5 mm - the mechanical length is optically not effective, as the adapter is completely sunken in the connection adapter

The 8" Ritchey-Chrétien is the perfect telescope for astrophotography, but it is also suitable for visual observation.

• ♦ Aperture 8" / 203 mm - focal length 1624 mm - focal ratio f/8
• ♦ Hyperbolic primary and secondary mirror for very high sharpness on the optical axis and a large well-corrected field for astrophotography
• ♦ Both mirrors made of fused silica for stable focus position
• ♦ 99% high-reflectivy coating on main and secondary mirror for an even brighter image and more contrast - special service from TS
• ♦ Quicker cooling down thanks to open construction and primary mirror ventilation
• ♦ Two Vixen style dovetail bars supplied - ideal for accessories like guiding scopes or a piggyback camera mount
• ♦ High-quality 2" dual speed MONORAIL focuser with 2" / 1.25" reduction adapter - motor focuser optionally available
• ♦ RC correctors for larger sensors from APS-C upwards are optionally available

The 2" CCD compressor reduces the focal length of telescopes with the factor 0.67x, thus allowing significantly shorter exposure times.

• ♦ The focal reducer is perfectly suitable for RC telescope. It also works good with Celestron EHD or Meade ACF telescopes or with refractors up to the focal ratio F/9
• ♦ The image field of DSLR cameras up to APS-C format is illuminated - full illumination up to 29 mm
• ♦ Easy connection to the telescope via 2" barrel
• ♦ Optimal working distance from the M48x0.75 thread to the camera sensor is 85 mm - enough space for accessories like off-axis guider or filter wheel
• ♦ 2" filter thread at the telescope side
