The scope comes with a factory installed vixen style mount for astro mounts, but is also tapped for use with a photo tripod providing the ultimate in flexibility. The unit provides tack sharp images and is great for lunar and planetary viewing. For astro use, I replaced the 45 degree prism with a 90 degree optional star diagonal to maximize performance. The scope is so light that when mounted to my photo tripod and video head, I can carry the whole set up outside in one trip. 90mm aperture provides enough light gathering for planetary and lunar viewing while keeping cool down time to a minimum.\"\u003c\/em\u003e\u003cem\u003e \u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ccenter\u003e\n\u003ch2\u003eCelestron C90 MAK Spotting Scope Specifications...\u003c\/h2\u003e\n\u003c\/center\u003e\n\u003cp\u003eOptical Design: Maksutov-Cassegrain\u003c\/p\u003e\n\u003cp\u003eAperture (mm): 90 mm (3.54 in)\u003c\/p\u003e\n\u003cp\u003eFocal Length (mm): 1250 mm (49 in)\u003c\/p\u003e\n\u003cp\u003eFocal Ratio: 14\u003c\/p\u003e\n\u003cp\u003eAngle: 0 or 45 degrees\u003c\/p\u003e\n\u003cp\u003eEyepiece 1 (mm): 32 mm (1.26 in)\u003c\/p\u003e\n\u003cp\u003eMagnification 1: 39 x\u003c\/p\u003e\n\u003cp\u003eFinderscope: 8x21\u003c\/p\u003e\n\u003cp\u003eCarrying Case: Backpack made of nylon\u003c\/p\u003e\n\u003cp\u003eHighest Useful Magnification: 213 x\u003c\/p\u003e\n\u003cp\u003eLowest Useful Magnification: 13 x\u003c\/p\u003e\n\u003cp\u003eLimiting Stellar Magnitude: 12.3\u003c\/p\u003e\n\u003cp\u003eResolution (Rayleigh): 1.55 arc seconds\u003c\/p\u003e\n\u003cp\u003eResolution (Dawes): 1.29 arc seconds\u003c\/p\u003e\n\u003cp\u003eLight Gathering Power (Compared to human eye): 165 x\u003c\/p\u003e\n\u003cp\u003eAngular Field of View (deg): 1.3 degrees\u003c\/p\u003e\n\u003cp\u003eLinear Field of View (@1000 yds): 68 ft (21 m)\u003c\/p\u003e\n\u003cp\u003eLinear Field of View (@1000 m): 23 m (75 ft)\u003c\/p\u003e\n\u003cp\u003eEye Relief (mm): 20 mm (0.79 in)\u003c\/p\u003e\n\u003cp\u003eNear Focus (Binoculars): 15 ft (4.57 m)\u003c\/p\u003e\n\u003cp\u003eOptical Coatings: Multi-Coated\u003c\/p\u003e\n\u003cp\u003eOptical Tube Length: 16 in (406 mm)\u003c\/p\u003e\n\u003cp\u003eWeight (lbs): 5 lbs (2.27 kg)\u003c\/p\u003e\n\u003cp\u003eCamera Adaptable: Optional T-Adapter\u003c\/p\u003e\n\u003cp\u003eTripod Adaptable: Yes\u003c\/p\u003e\nCelestron Product Number: 52268","brand":"Celestron","offers":[{"title":"Default","offer_id":10554663745,"sku":"CEL-52268","price":249.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/2526-1-thumb.jpeg?v=1776458933","url":"https:\/\/khanscope.com\/en-fr\/products\/c90-mak-spotting-scope-52269","provider":"Khan Scope Centre","version":"1.0","type":"link"}
