Configuration and Balancing

Configuration and Balancing of the EQ-AL55i Pro Mount

  1. Counterweight Bar Position (Fig.5 to Fig.7)
  2. The EQ-AL55i Pro mount offers two mounting positions for the counterweight bar. The classic position is suited for higher latitudes (Fig.5).
  3. The position of the counterweight bar is more suited for an observation site in lower latitudes(Fig. 7).
  4. Balancing the Telescope (Fig.6 to Fig.8)
  5. Loosen DEC clutch lever (Fig.1, 2) and RA clutch wheel (Fig.1, 1) and put the mount in such position that the counterweight is in its lowest position. Make sure the DEC clutch lever (2) and RA clutch wheel (1) are tightened again and the telescope locking screw(Fig.4, 19) is loose. Put the telescope on the mount, lock it with the telescope locking screw (19). Check the DEC axis balance by loosening the DEC clutch lever (2) while holding the telescope. Make sure the telescope is balanced by mounting it accordingly in the telescope mounting clamp .
  6. Loosen the RA clutch wheel (1) and put the counterweight bar in a horizontal position as shown in Fig.6 and Fig.8. Check the balance of the mount, and shift the counterweight on the counterweight bar as needed.EQUATOR-EQ-AL55J-1SP-Skywatcher-Mount-on-Steel-Tripod-fig-1 \(6\)

Polar Alignment with Polar Finder

  1. 1. Find the position of the star Polaris or Stella Octans with a smartphone and the Synscan Pro app, or another app showing Polaris/Octans position compared to true north/south.
  2. Orient the polar scope in the RA axis in such way that 0 is up and 6 is down (Fig.9).
  3. Shift Polaris/Octans to the position indicated by the app. This movement of Polaris/Octans must be done by using the latitude adjustment lever (Fig.2, 4) and the azimuth adjustment knobs (Fig.2, 5).
  4. Users can obtain moderate accuracy on polar alignment with the help of the polar scope. For best polar alignment, use the drift alignment method, or camera-aided polar alignment software like PHD2 or SharpCap.
  5. For observing in the Northern Hemisphere: find Polaris (the brightest star near the North Celestial Pole) in the polar scope by adjusting the angle of the equatorial wedge. Use the SynScan Pro app to find the corresponding orientation of Polaris in the polar scope by simply entering the date, time, longitude and latitude of your observing location. The polar scope utility can be found under “Utility” and then “Advanced”. A pattern similar to fig. 9 showing where Polaris should be located, is represented in the app. Move Polaris to that corresponding position in the polar scope by using the fine-tuning movements of the equatorial wedge (see fig. 2 knob 4 and fig. 1 knobs 5).
  6. For observing in the Southern Hemisphere: locate in the polar scope the four dim stars (around Magnitude 5 to 6) which form the pattern “Octans” (see drawing in the polar scope as Fig. 10 and Fig. 10a). Align the orientation of the “Octans” drawing to the four stars. Then move the four stars to the four small circles of the “Octans” drawing by using the fine-tuning movements of the equatorial wedge (see fig. 2 knob 4 and fig. 1 knobs 5).EQUATOR-EQ-AL55J-1SP-Skywatcher-Mount-on-Steel-Tripod-fig-1 \(7\)

Operating Your Telescope

Aligning and using the finderscope / red dot finder

  1. These fixed magnification scopes mounted on the optical tube are very useful acces-sories. When they are correctly aligned with the telescope, objects can be quickly located and brought to the centre of the field. Alignment is best done outdoors in daylight when it’s easier to locate objects. If it is necessary to refocus your finderscope, sight on an object that is at least 500 meters (or yards) away. For the 6×30 finderscope: loosen the locking ring by unscrewing it back towards the bracket. The front lens holder can now be turned in and out to focus. When focus is reached, lock it in position with the locking ring (Fig.21).
    • Choose a distant object that is at least 500 meters(yards) away and point the main telescope at the object. Point the telescope exactly to have the object well-centred in the eyepiece of the telescope.
    • Check in the finderscope if the same object is also well-centred on the crosshairs.
    • For the 6×30 finderscope with spring loading, adjust only the two small screws (Fig.22)EQUATOR-EQ-AL55J-1SP-Skywatcher-Mount-on-Steel-Tripod-fig-1 \(18\)
  2. Aligning and using the red dot finder
    • The Red Dot Finder is a zero magnification pointing tool that uses a coated glass window to superimpose the image of a small red dot onto the night sky. It is equipped with variable brightness control, azimuth adjustment control, and altitude adjustment control (Fig.23). The red dot finder is powered by a 3V lithium battery located under a removable cover. When new, this battery may be protected by a plastic strip which should be removed before use. To use it, simply look through the sight tube and move your telescope until the red dot merges with the object. Make sure to keep both eyes open when sighting.
    • Like all finderscopes, the red dot finder must be properly aligned with the main telescope before first time use. This is a simple process using the azimuth and altitude control knobs (fig. 23).
    • Check if the plastic strip protecting the new battery has been removed. The battery is located under a cover. This location can differ in different red dot finderscope models (fig.24).
    • Turn on the Red Dot Finder by rotating the variable brightness control clockwise until you hear a “click”. Continue rotating the control knob to increase the brightness level.
    • Insert a low-power eyepiece into the telescope’s focuser. Locate a bright object and position the telescope so that the object is in the centre of the field of view.
    • With both eyes open, look through the sight tube at the object. If the red dot overlaps the object, your Red Dot Finder is perfectly aligned. If not, turn its azimuth and altitude adjustment controls until the red dot is merged with the object.EQUATOR-EQ-AL55J-1SP-Skywatcher-Mount-on-Steel-Tripod-fig-1 \(19\)

Focusing the telescope

  • Slowly turn the focus knob one way or the other, until the image in the eyepiece is sharp (fig.5.2a). Check if the accessories and adapters you use are corresponding to the instructions of the manual if a sharp image cannot be reached. Another cause may be that the object you are aiming at with your telescope is too close.
  • Refocusing is almost always necessary when you switch eyepieces.EQUATOR-EQ-AL55J-1SP-Skywatcher-Mount-on-Steel-Tripod-fig-1 \(20\)

Choosing the appropriate eyepiece

  • The magnification produced by a telescope is determined by the focal length of the eye-piece that is used with it. To determine a magnification for your telescope, divide its focal length by the focal length of the eyepieces you are going to use. For example, a 10mm focal length eyepiece will give 80X magnification with an 800mm focal length telescope.
  • When you are looking at astronomical objects, you are looking through a column of air that reaches to the edge of space which seldom stays still. Similarly, when viewing over land you are often looking through heat waves radiating from the ground, house, build-ings, etc. Your telescope may be able to give very high magnification but you end up magnifying all the turbulence between the telescope and the object. A good way to choose the right eyepiece for observation of bright objects (moon, planets etc.) is to start with a low power eyepiece, and increase the magnification step by step until you get the impression that increasing magnification does not provide more details in the image. A rule of thumb is that the maximum magnification is (with exceptionally good weather conditions) 2x the diameter in mm of the telescope.
  • To look for faint objects (nebula etc.), a very low power eyepiece is recommended because magnifying more also means a darker image, and inversely, a lower magnification produces a brighter image. A lower magnification also shows a wider view of the sky, which also helps finding objects. The minimal useful magnification (= maximum brightness) of a telescope is 0.14x the diameter in mm of the telescope. Conclusion: every search in the sky starts by looking in the finderscope, then look in your telescope equipped with a low power eyepiece having a bright and wide view on the sky. After having found and centered the object in the low power eyepiece, magnification can be increased step by step by switching to more powerful eyepieces if weather conditions (air turbulence) and the brightness of the object allows it.

Observing the sky

Sky Conditions

  • Sky conditions are usually defined by two atmospheric characteristics, seeing, or the steadiness of the air, and transparency, light scattering due to the amount of water va-pour and particulate material in the air.
  • When you observe the Moon and the planets, and they appear as though water is run-ning over them, you probably have bad “seeing” because you are observing through tur-bulent air. In conditions of good “seeing”, the stars appear steady, without twinkling, when you look at them with unassisted eyes (without a telescope).
  • Ideal “transparency” is when the sky is inky black and the air is unpolluted.

Selecting an Observation Site

  • Travel to the best site that is reasonably accessible. It should be away from city lights, and upwind from any source of air pollution. A
  • ways choose as high an elevation as possible; this will get you above some of the lights and pollution and will ensure that you aren’t in any ground fog. Sometimes low fog banks help to block light pollution if you get above them.
  • Try to have a dark, unobstructed view of the horizon, especially the southern horizon if you are in the Northern Hemisphere and vice versa. However, remember that the darkest sky is usually at the “Zenith”, directly above your head. It is the shortest path through the atmosphere.
  • Do not try to observe any object when the light path passes near any protrusion on the ground. Even extremely light winds can cause major air turbulence as they flow over the top of a building or wall.
  • Observing through a window is not recommended because the window glass will distort images considerably. And an open window can be even worse, because warmer indoor air will escape out the window, causing turbulence which also affects images.
  • Astronomy is an outdoor activity. The best conditions will have still air, and obviously, a clear view of the sky.
  • The sky doesn’t need to be cloud-free. Often, broken cloud conditions provide excellent seeing.

Choosing the Best Time to Observe

  • Do not view it immediately after sunset. After the sun goes down, the Earth is still cooling, causing air turbulence. As the night goes on, not only will seeing improve, but air pollution and ground lights will often diminish. Some of the best observing time is often in the early morning hours.
  • Objects are best observed as they cross the meridian, which is an imaginary line that runs through the Zenith, due to North-South. This is the point at which objects reach their highest points in the sky. Observing at this time reduces bad atmospheric effects.
  • When observing near the horizon, you look through lots of atmosphere, complete with turbulence, dust particles and increased light pollution.

Cooling the Telescope

  • Telescopes require at least 10 to 30 minutes to cool down to outside air temperature. This may take longer if there is a big difference between the temperature of the telescope and the outside air. This minimizes heatwave distortion inside telescope tube (tube currents). Allow a longer cooling time for larger optics.

Adapting Your Eyes

  • Do not expose your eyes to anything except red light for 30 minutes before observing. This allows your pupils to expand to their maximum diameter and build up the levels of optical pigments, which are rapidly lost if exposed to bright light.
  • Observe with both eyes open. This avoids fatigue at the eyepiece. If you find this too distracting, cover the non-used eye with your hand or an eye patch. Use averted vision on faint objects: The center of your eye is the least sensitive to low light levels. When viewing a faint object, don’t look directly at it. Instead, look slightly to the side, and the object will appear brighter.

Proper Care for Your Telescope

  • Cleaning Your Telescope
    • Replace the dust cap over end of telescope when not in use. This prevents dust from settling on the mirror or lens surface.
    • Do not clean the telescope mirror or lens surface unless you are familiar with lens surfaces. A little dust on these surfaces will not noticeably affect the image quality. Contact your dealer for advice if these surfaces are more dirty than just some dust.
    • Eyepieces will get dirty more quickly due to contact with eyelashes etc. Their optical surface is less sensitive and can be cleaned regularly with soft cloth and cleaning fluid suited for optical surfaces.
