WARNING:
DO NOT USE THIS TELESCOPE OR ANY ACCOMPANYING FINDER SCOPE TO LOOK AT OR NEAR THE SUN UNLESS YOU ARE USING A SPECIAL SOLAR FILTER! EVEN MOMENTARY
VISUAL CONTACT WITH THE SUN'S LIGHT RAYS CAN INSTANTLY CAUSE IRREVERSIBLE DAMAGE TO YOUR EYE(S). EYE DAMAGE CAN BE PAINLESS, SO THERE IS NO WARNING TO
THE OBSERVER THAT DAMAGE HAS OCCURRED UNTIL IT IS TOO LATE. TAKE EXTRA CARE WHEN USING THE TELESCOPE OR A FINDER SCOPE DURING DAYLIGHT HOURS, AND DO
NOT POINT EITHER AT OR NEAR THE SUN. DO NOT LOOK THROUGH EITHER WHEN YOU ARE MOVING THE INSTRUMENTS DURING THE DAYTIME. NEVER ALLOW ANYONE TO USE
THE TELESCOPE OR A FINDER SCOPE DURING THE DAYTIME WITHOUT WARNING THEM OF THE HAZARDS OF AIMING EITHER AT OR NEAR THE SUN. MAKE SURE THAT THEY ARE
ADEQUATELY TRAINED ON THE USE OF THESE INSTRUMENTS BEFORE ALLOWING THEM TO START OBSERVING. CHILDREN SHOULD ALWAYS HAVE INFORMED AND TRAINED ADULT
SUPERVISION WHILE OBSERVING.
WARNING:
The lens contains lead that may be harmful.
Wash hands after touching.
SUN HAZARD — Never look directly at the sun with this device.

    Unboxing and Checking Contents Please Note: We recommend that you keep the original shipping box and packing materials if possible, in case your scope should ever need to be returned for service or warranty purposes. Inside the main package, you will find: –...
  • Page 5 Unboxing and Checking Contents Figure 3 After removing the trusses, you will find two boxes (Figure 3). The smaller one contains the mirror box and the other contains the rocker box. On the outer left you can see one of the altitude wheels, the stray light cover for the secondary cage is visible in the upper part of the box.
  • Page 6: Assembly

    Assembly We suggest reading all this manual in it’s entirety before attempting assembly. If you are assembling your telescope for the first time, we recommend doing so in a warm room. First, place the mirror box onto a table to attach the altitude wheels to the mirror box. You will notice that each altitude wheel has two holes.
  • Page 7 Assembly Now look at the mirror box from above. You will notice threaded rods that are sticking out of the corners of the mirror box. There is a wing nut riding on each of those inward pointing threaded rods. Unscrew the wing nuts to the end of the threaded rods, making sure that they don´t come off and risk falling onto the main mirror.
  • Page 8: Collimation

    Collimation Collimating the optical systems Although the optics in your telescope were carefully collimated in our quality control department prior to leaving our facility, we recommend collimating the telescope after reassembly. The whole procedure is straightforward and should takes only a few minutes after reassembly, if you have numbered your trusses and reassemble your telescope the same way it had been assembled.
  • Page 9 Collimation Adjusting the main mirror Once the secondary appears round and the mark on the main mirror is centered, check the collimation of the main mirror. If the reflection of your eye and the reflection of the secondary mirror on the main mirror are not concentric, insert the collimating tool into one of the collimation screws that are located on each side of the main mirror.
  • Page 10 Collimation Fine Collimation NOTE: Please take care that the telescope has time to adapt to the ambient temperature before starting collimation – this will need up to 30 minutes (otherwise you will not get a good star image). You may use the fans to speed up this process.
  • Page 11: Using A Dobsonian Telescope

    Using Your Dobsonian Your Explore Scientific Dobsonian is a precision optical instrument and should be used with care. Try to avoid exposing your telescope to vibrations because this may cause the telescope to lose collimation. Aligning the viewfinder The red dot that is used by the finder scope is not readily visible during the day. For this reason you should align the finder scope once it is dark.
  • Page 12: Observing

    Observing Astronomical observations The first observations should be performed during dusk so that you get familiar with your new telescope quickly. Always remember never to look at or near the sun! Choose a land object that is easy to find and far away, such as a mountain top.
  • Page 13 Observing Deep-Sky Objects To locate constellations, stars or other deep-sky objects, it makes sense to use a star chart. We will list a selection of deep sky objects here: Stars are giant objects that mainly consist of gas. Due to the nuclear fusion in their core they radiate energy and shine.
  • Page 14: Hints And Tricks

    Hints and Tricks Marking with luminous paint: As noted above in the section about assembly it is very helpful to mark the positions of the altitude wheels and the trusses. This helps when assembling the telescope at night and keeps collimation issues at a minimum.
  • Page 15: Calculating Magnification

    Hints and Tricks Calculating magnification The magnification of a particular telescope configuration is determined by two factors — the focal length of the telescope and the focal length of the eyepiece. You will find the focal length of almost all eyepieces written on the eyepiece body.

    Service, Maintenance and Accessories Your Explore Scientific truss Dobsonian is a precision instrument that will provide many years of fun. When you are treating this telescope with the same care as, for example, an expensive camera, it is very unlikely that you will ever need to return it for service or maintenance.
