Fast travel apochromat for astrophotography and observation with 80 mm aperture
The triplet objective with 80 mm aperture and 480 mm focal length convinces with a very good chromatic correction due to the FPL53 APO element. It is one of the best 80 mm apochromatic lenses in the range of Teleskop-Service.

The 3-element 0.8x image field corrector is designed for 80 mm f/6 triplet apos and brings full correction up to full frame. The corrector is screwed to the 2.5" rack and pinion focuser to prevent tilting. The working distance from the M48 thread is 55 mm, which simplifies the adaptation of astro cameras. A 2" filter thread is also integrated in the camera adapter.

Best mechanics guarantee excellent imaging for years and success in astrophotography
The best optics can only be used successfully if the mechanics are right. With this photo apo, we have placed a lot of emphasis on first-class components.
Rigidly mounted focuser with rack & pinion (gear drive) adjustment. The bearing is decoupled from the adjustment of the draw tube.
Oversized draw tube with 60 mm clear aperture for full illumination even at full format.
1:10 dual-speed for ultra-accurate focusing
High-quality CNC tube with inner baffles and very good inner blackening - no disturbing stray light
M63x1 female thread on draw tube
M68x1 female thread on the connection adapter, to get to the thread 3 grub screws have to be loosened.
The dew shield can be pushed in - the transport length is then only 37.5 centimeters
Modern and multicoated 3-element objective with APO element made of FPL53
High-quality CNC rings and GP style dovetail bar with photo tripod connection
Tube rings each have three M6 threaded holes on top, one in the center and two with 30 mm center distance
Finder shoe is already mounted

The visual use - spotting scope and astronomical travel telescope
Although the apo is optimized for astrophotography, it can also be used visually very well. Simply unscrew the corrector and insert the 2" receptacle. Now you can observe through the telescope with 1.25" or 2" star diagonal or Amici prisms and magnify up to about 200x with very high contrast.

Question:
How do I access the M68 and M63 connection threads?

Answer from Teleskop-Service:
To access the M68x1 internal thread, the 2" adapter must be unscrewed. The 2" adapter is secured by three small grub screws, which must be loosened first. To access the M63x1 internal thread, the M68x1 adapter must also be unscrewed from the extension tube. This adapter is also secured by three small grub screws. The adapter can only be unscrewed once these have been loosened
