Actual product photo: Color box dimensions: 44.5x11.5x22.5cm Box dimensions: 46x45.5x60.3cm Whole box gross weight: 16.4kg Individual gross weight: 1.52kg F30070 standard version configuration: one main mirror tube, two eyepieces H6mm, H20mm, one 3X magnification lens, one 1.5X erect image lens, one tripod, one adjustment lever, and a manual Model: F30070M Light transmission aperture: 70mm2.4 Focal length: 300mm.f/4 Inclined mirror: 90 Meridian table and aluminum tripod Maximum height: 38cm Standard 0.965inch attachments include: Eyepiece: H6mm, H20mm 3x Barlow lens, 1.5x erect image lens The maximum magnification of this model: 150 times the objective lens focal length/eyepiece focal length * the Barlow coefficient = maximum magnification The aperture is the most important criterion when choosing a telescope; the aperture is directly proportional to the clarity and price ARegarding functionality: This one has a gross weight of about 1..6 kg and is an island in the The shape of a ring from which you can see the moon. If you want a completely inverted image, you can refer to the store's 70060 fully inverted version, which allows direct viewing. Tripod height: 38CM BRegarding configuration: Thefocallengthis300mmtheopeningsis70mm,anditcomeswithtwoeyepieces:H6fordaytimeviewingandH20fornighttimemoonviewing,inadditiontoa3xBarlowlens,a1.5xerectinglens,andamoonlensMoonMirror:Whenobservingthefullmoon,thereisalotofreflectedlightthatcausesinterferenceUsing a moon mirror can eliminate these disturbances, allowing the lunar surface to be seen more clearly. When using it, please screw the moon mirror into the threads at the bottom of the eyepiece, then attach the eyepiece to the zenith mirror C. Regarding multiples: With different eyepieces: the magnification for H6mm and H20mm is: 300/6=50x, 300/20=15x. If a 3x Barlow lens is added, the magnification will be 50X3=150x, 15X3=45x; and if a 1.5x erecting lens is added, the magnification will be 15X3=45x Once added, the image will be erect, and the magnifications will be: 50X1.5=75x, 15X1.5=22.5x. That is: Minimum magnification: 15x, Maximum magnification: 150x D. Calculation formula: Objective lens focal length/eyepiece focal length * Barlow coefficient = maximum magnification Objective lens focal length/eyepiece focal length = magnification E.

When using a 3x Barlow lens, first install the Barlow lens, then install the eyepiece To install the Barlow lens, you need to remove the cover from the device that holds the eyepiece H. Note: 2 eyepieces H6m m,H20mm can only have one installation selected at a time You can only choose one of the two: a 3x Barlow lens or a 1.5x positive image lens Of course, magnification is not the only factor; it mainly depends on comprehensive factors such as caliber and focal length For example, if a house's windows are large, the light will naturally be better, and the view will be clearerIt's the same principle The Ningbo Phoenix series offers great value for money and is suitable for beginners in astronomyIt doesn't cost much, yet allows one to appreciate the mysteries of the celestial world all over the world
