Description
Fast Newtonian imaging and modular equatorial integration define the Levenhuk N 200/1000 Ra 200N F5 OTA, a standalone 200 mm parabolic reflector with a 1000 mm focal length and listed f/5 optical ratio. Its steel optical tube includes a dual-speed 2-inch focuser with 10:1 reduction, hinged cradle rings, Vixen dovetail, 8×50 finder, 35 mm extension tube, rear cooling fan, and mounting hardware for a separately selected telescope platform.
The OTA is intended for deep-sky observation, nebula imaging, planetary viewing, and supported astrophotography after installation on a compatible mount and tripod. The 200 mm aperture and fast f/5 configuration require careful collimation, mount capacity, payload balancing, camera spacing, focus adjustment, and thermal preparation, while the rear fan can be used during cooldown before detailed observation or imaging.

Standalone Deep-Sky Imaging Configuration
The supplied application focuses on deep-sky photography, nebulae, galaxies, clusters, lunar observation, and planetary viewing using a standalone fast Newtonian tube, while final tracking, payload support, guiding, collimation, focus spacing, camera compatibility, and imaging results depend on the separately selected mount, tripod, counterweights, camera, and accessories.
Why Choose Levenhuk N 200/1000 Ra 200N F5 OTA
The Ra 200N F5 OTA is relevant when a custom telescope system needs a 200 mm parabolic reflector with fast f/5 optics, dual-speed focusing, active cooling, Vixen mounting, heavy cradle rings, an 8×50 finder, extension tube, and an open path for choosing the final equatorial or other compatible mount separately.
- 200 mm aperture with fast f/5 optical format
- Dual-speed focuser with active rear cooling
- Rings, dovetail, finder, extension tube, and OTA hardware included
Levenhuk Lifetime Warranty
Current Levenhuk regional product listings commonly present lifetime warranty language, while the applicable US warranty terms for this optical tube should be confirmed before purchase, including mirror coverage, focuser coverage, cooling-fan coverage, mounting hardware coverage, registration requirements, and authorized service conditions for the selected retailer or distributor.
