About this product

Model:  ts_flat25_del
Part Number:  TSFlat25Del

Suitable for use with United Optics ED refractors (various brands) from 700 mm focal length. 

Can also be used with GSO RC telescopes (StellaLyra, TS-Optics, Astro Tech, etc) from 10 "aperture. 

Features: 

  • An M48x0.75 filter thread in the camera adapter enables use of 2" filters
  • The corrector does not change the focal length - factor 1.0
  • The position of the focal plane of the refractor is not changed.

Specification:

Connection telescope side: M63x1 external thread
Connection camera side: M48x0.75 external thread and M63x1 internal thread
Working distances: 55 mm from the M48x0.75 external thread and 73 mm (if you omit the M63 extension) for focal lengths from 700 mm
Maximum working distance from the M63x1 Internal thread: 85 mm - enough space for almost all adaptations
Full Illuminated and corrected image field: 45 mm full format

The TSFLAT25Del offers two options for connecting the camera:

The working distances apply to refractor telescopes with focal lengths from 700 mm. Please see below for information regrading shorter focal lengths.
There is an M63x1 internal thread directly on the corrector. The generous working distance from this thread is 85 mm. This gives you enough space for accessories such as filter wheels, off-axis guiders and much more.
The scope of delivery also includes a transition adapter to M48x0.75. The working distance from this thread is exactly 55 mm. This is ideal for connecting DSLR cameras (simply T-Ring + camera) or astro cameras. The adapter makes sense if the camera is to be connected directly to the corrector.

The flattener might also be suitable for use with telescopes with a similar focal length and aperture ratio:

With a focal length of 700 mm, a working back focus distance of 55 mm applies from the M48 thread with the M63 extension tube.

Refractors between 600 mm and 700 mm focal length: The working distance is increased by 5 mm
Refractors between 500 mm and 600 mm focal length: The working distance is increased by 10 mm
