Apochromatic telescope 154mm f/4 astrograph for astrophotography

Apochromatic telescope 154mm f/4 astrograph for astrophotography combines speed, sharpness and simplicity in one bright reflector. With an aperture ratio of f/4 and a high-quality 94% reflective coating on the parabolic main mirror, this is the telescope for astrophotographers who want fast results.

The short tube length makes this 6-inch astrograph ideally suited for use on medium-sized mounts without sacrificing image quality. The large capture mirror provides full exposure for APS-C and DSLR cameras without vignetting - ideal for wide deep-sky objects.

✓ Parabolic primary mirror (f/4) with 94% reflectance for short exposure times
✓ Compact design - works on lighter mounts
✓ 2″ Crayford focuser with 1:10 microreduction and high carrying capacity
✓ Optimized for deep-sky astrophotography with wide angle of view
✓ Includes tube rings, Vixen-style dovetail and extension piece

This reflector is not only suitable for photography, but can also be used visually with 2″ wide field eyepieces. Thanks to the built-in fan, the main mirror cools down quickly, allowing you to get started faster with sharp shots under the stars.

Application

• Deep-sky astrophotography (nebulae, galaxies, clusters)
• Photography with DSLR and CMOS cameras
• Quick setup with compact EQ5/EQ6 mount
• Visual use with 2″ eyepieces (widescreen)

What you can see with it

✓ Structures in nebulae such as Orion, Rosette and Veil Nebula
✓ Galaxies such as M31, M81, M101 with lots of detail
✓ Bright globular clusters and open clusters
✓ Wide sky fields without vignetting (when using corrector)
✓ Perfect combination of speed and image quality for novice photographers
