Product description

This apochromat with a 70 mm aperture and 350 mm focal length was specially developed for astrophotography. It offers a fully illuminated and corrected field with a diameter of 45 mm, making it suitable for cameras with full-frame sensors. The FPL53 triplet lens corrects chromatic aberration. The image is free of chromatic aberration on the axis and in the field.

On the camera side , the Apo has an M48x0.75 external thread, and with a bayonet adaptor suitable for your camera, you can screw a DSLR directly onto it. From the T2 thread, you have between 40 mm and 70 mm distance to the focal plane, depending on the position of the extension tube. This gives you enough space for all common astro cameras, SLR and system cameras.
If you unscrew the M48 adaptor, you will find an M54x0.75 internal thread. This gives you an additional 6.5 mm of optical travel. A 2" filter thread is integrated into this adaptor.

Scope of delivery:

  • Imaging Star 70 mm Apo
  • CNC tube clamps
  • Vixen level prism rail with photo tripod connection
