Astronomical Telescope

Detailed Product Description


  Astronomical Telescope

Will be aluminum foots rest take out from case, extending reach suitable length from upper to lower and lockwasher knob.

   Foot legs and tripod base will connect with long screw and wing nut each other. Bracket will lock on the level lockwasher knob, then connecting rod will be connected to fix on foot rest with short screw and external hoxagonal nut each other. And by pitching rod lockwasher knob will primary lens canister fixed on support. Inching pitching rod will install on primary lens canister, and by inching lockwasher knob screw on.

   Will open aluminum foots rest and put it on accessory tray, then lock on wing nut of tripod.

   Finder bracket will aim at two root of screw on primary lens canister, then lightly insert it into two root of screw on primary lens canister, to fixed on finder by finder screw nut.

   Will insert zenith lens into eyepiece joint canister and by screw on screw.

   Please you select suitable size eyepiece, then install into zenith lens and screw on screw, that is, observation.

   If you need to use 1.5x positive image lens (or 3x Pakistan Love lens), please will remove zenith lens, will direct eyepiece install into 1.5x positive image (or 3x Pakistan Love lens), then connected to eyepiece joint canister again, and will screw on screw, that is, may observed.

Eyepiece and Times Explanation

   Times mean that astronomical telescope ability of magnification object, or the better nicety say that object image zoom in ability, times is general express with x, for instance: You suppose that to observe object with 35x, represent to be zoom in 35x the distance between you and object. So astronomical telescope magnified times mean that primary lens focus divided by eyepiece focus and you get magnification times. (For instance object lens of Star 70060 is 700mm, eyepiece focus is 8mm, 125mm and 20mm).

1.     Attention

l     It based on astronomical telescope observation basic principle, the much suitable magnification times of each astronomical telescope is 2 times of object lens diameter of the primary lens canister (60mm is object lens diameter of primary lens canister of the Star 70060), magnification times under the principle, will presented image has not dim phenomenon.

l     1.5x of positive image lens: After use 1.5x positive image lens, may acquire complete positive image and will origin magnification times add to 1.5x, but after used, due to times increase will have observe object image more dark.

l     3x of Pakistan Love lens: After installed 3x of Pakistan Love lens, may have it origin magnification times add to 3x. 3x of Pakistan Love lens use is observe much bigger and much bright stars for convenience, eg, moon.

l     Moon lens: Because observe full moon will have disturb a great of reflection light, moon lens in use may remove the interference, lets see the much clear on moon surface. Please, after moon lens will screw on whorl of lower part of eyepiece when use, eyepiece will connect on zenith lens again.

The Finder Adjustment

   Thanks to the astronomical telescope times is big, field of view is small, it is very difficult to look at remote distance target when observe. We have to rapid find target by finder.

   First, will put eyepiece into zenith lens, random look for in a 300m may observe immovable target, movement by level of lift and right and uplightness of up and down, permeation eyepiece may get observation target at due center of field of view. After it adjustment focus have it clear image, after adjusted, will lock on pitching rod lockwasher knob and level lockwasher knob again, have image will not move.

   Now permeation finder again to observe anteriority will be observed object, when anteriority will be observed image can not complete present in finder, please screw off finder nut, to adjust finder until anteriority will observed object can clear stand for cross line center of field of view of finder, at the moment, will fix on finder nut, let the light axis of finder and primary lens canister parallelism. When observing at next time, that is, may utilize finder find observation body, permeation primary lens canister target again to observe the object.

Level Pitching Device

   Telescope per stand are have a level pitching device made primary lens canister can revolve on level and vertical plane. On level, your telescope may revolve 360 degree, level lockwasher knob may random locked on level position. On vertical plane, when screw off lockwasher knob of pitching rod. astronomical telescope may from change on level position to almost close vertical position.

   The device has inching control of pitching direction (pitching inching knob), may easy pursue track of revolving object. There is level pitching device has not do move tripod, will may observe random movement stars position in the sky.

Lens Maintain

   Lens is very important and is also very easy part of loss in astronomical telescope parts. For in case influence precision and property, please will not random knock down lens and as far as possible decrease clean up lens, if would rub lens will also careful as instruction below to do:

   First should remove dust with professional hairs brush, then drop a few drip alcohol on neat cotton, light rub along a direction (dont rub a loop and a loop), then flick off residual trace and dust by brush.

   When telescope will from outdoor (low temperature) to indoor (high temperature), due to factor of difference in temperature have easy coated with a layer of mist in eyepiece, if appear the circumstance, the better method is will telescope move into beside heat source (eg: Grate and warm stove), have mist will steam bit by bit. As soon as complete dry then careful wipe residue on eyepiece. Under cold climate, if you need to observe at outdoor, please, will first astronomical telescope will installed at outdoor a half hour ago when would like observe, thereby in case happen circumstance above.

Note:

   In any circumstance arent direct observes sun by permeation finder and primary lens canister, or else will loss your eyes.
