(2-2) 3 Azimuth Adjustment Knob pillar to Lock Knob Post Tighten the azimuth adjustment knobs on the mount base so that the t wo knobs are set equally. 2-3 Azimuth Adjustment Knobs 10 PREPARATION Tips on Assembling the Mount Generally equatorial mounts are heavier on the declination axis side. Because of this feature, placing the equatorial mount so that its declination axis comes directly over one of the tripod legs can make the equatorial mount most stable when you use the equatorial mount for a north (or south) latitude of 50 degrees and lower. However, the balance of the equatorial mount may vary if the equatorial mount is used in latitude higher than 50 degrees. This may result in shifting the center of balance to the opposite side of the declination axis depending on the location of the loading equipment. Change the position of the tripod legs so that the equatorial mount becomes more stable in such a case. Attaching the Counterweight The counterweight bar is in the declination body. You may balance the SX2 mount with only the counterweight bar to start. CAUTION: Be sure to handle the counterweight carefully as it is very heavy. 1 Loosen the counterweight bar lock lever to draw out the counterweight bar. Lock Lever Tighten the counterweight bar lock lever with the counterweight bar extended fully. Counterweight Bar 2 Remove the safety screw on the end of the counterweight bar. Loosen the lock knob on the side of a counterweight and install the counterweight by sliding it onto the counterweight bar. Safety Screw 3 Attach the counterweight so that the lock knob on the counterweight is on the far side of the safety screw as shown in the figure. Lock Screw Far Side Lock Screw Counterweight 4 Tighten the counterweight lock knob and replace the safety screw to screw it down on the end of the counterweight bar tightly. Safety Screw 11 PREPARATION Attaching the Optical Tube The telescope attaches to the SX2 mount via a dovetail tube plat or a dovetail slide bar. CAUTION: Take care not to drop the optical tube as it could result in serious damage. Make sure that the slide bar or dovetail tube plate is flat against the saddle plate. Tightening the lock screws with a gap between these parts may cause the telescope to fall. The ED103S shown as an Example: 1 Loosen the lock knob and the safety screw on the mount head before you attach the optical tube.

Safety Screw Lock Knob 12 PREPARATION Balancing the Equatorial Mount The Vixen SX2 mount is a German equatorial mount, in which the rotating RA axis and rotating DEC axis cross each other at right angle. The axes are rotated by using the movement of both axes to get maximum stability and limit the stress on the gears. If the equatorial mount is in an unbalanced state, it will increase stress to the gears and this could result in damage or erratic operation. Precise slewing requires a high level of accuracy in rotation of both axes and is important in eliminating stress to the gears. Make sure to balance the equatorial mount properly in RA and DEC accordingly. An optical tube weighing 1.2kg (2.6 lb.) or less cannot be balanced with the SX2 mount. Note: Take care not to drop the optical tube assembly as it could seriously damage the equipment or lead to injury. Pay close attention to the security of the telescope tube and do not excessively loosen the lock knobs on the equipment. Balancing the Mount in Declination 1 In case of Optical Tube Assembly with Dovetail Slide Bar Loosen the R.A. clamp while holding the counter weight bar (1-1) and 1-1 turn the telescope tube until the DEC. a xis comes to horizontal (1-2). loosen the DEC. clamp. 1-2 2-1 Decl.

Finder Field of view 20 Finder Field of view APPLICATION Using the Polar Axis Scope The polar axis scope is a small telescope that is installed parallel to the R.A. axis of an equatorial mount so that the polar axis scope can precisely point to the north (or south) celestial pole. Accurate polar alignment is essential for successful long exposure astrophotography of deep sky objects with the equatorial mount. Check longitude and latitude of your observing site with a GPS system or a map before the polar alignment. The polar axis scope allows you to accurately align the mount to Polaris at 3 arc minutes or less. Note: * Inaccurate polar alignment could result in trailed stars and field rotation in your imaging device. * It is not possible to use the SX2 mount in the north latitude over 70 degrees and in the south latitude over 70 degrees.

Unlike Polaris which is a bright 2nd magnitude star adjacent to the north celestial pole, Octans is made up of dark stars about 5th magnitude on average. The nearest star to the south celestial pole is Sigma Octantis, which is one of four stars forming a trapezoid in Octans, visible at 5.5th magnitude. There are a few methods to locate inconspicuous Octans using the surrounding stars.

Directing to Octans using Small Magellanic Cloud and the Southern Cross (Crux) as pointers Draw an imaginary line between the center of Small Magellanic Cloud and Beta Crux and divide it at a ratio of one to two. You will find the four stars of Octans at the divide. 2. Directing to Octans using the arrangement of stars in the Southern Cross (Crux) as pointers Draw an imaginary line straight through the two stars (Alpha and Beta Crux) of the Southern Cross making the vertical line of the cross toward Small Magellanic Cloud. You will find the four stars of Octans at a place about 4.5 times extended from the span of the two stars. 3. Directing Octans using Small Magellanic Cloud, Beta Hydrus and Gamma Octantis as pointers If you cast your eyes toward Crux from Small Magellanic Cloud, you will see Beta Hydrus. Going southward from Beta Hydrus will find you Gamma Octans which consists of a row of three stars. Continue on your eyes by the same distance toward the Southern Cross and you will find the four stars of Octans. 24 APPLICATION The polar axis scope contains a reticle showing the relative positions of four stars near the southern celestial pole. The stars are Sigma, Tau, Chi and Upsilon of Octans. Polar align the mount with these four stars but precession is not considered. 1 2 3 4 5 Set up the mount and telescope in a flat and hard ground where you can see Octans in the sky. Point the polar axis of the SX2 mount in the direction of south. Adjust the tripod legs so that the tripod is as level as possible. Take off the declination cap and polar axis cap. These caps can be removed readily by twisting counter-clockwise. Turn on the power switch of the mount. Refer to set up procedures 4 to 7 that are described for the use in the northern hemisphere. While looking into the eyepiece of the polar axis scope, turn the χ alternately so that the four stars of Octans comes into the field of τ view of the polar axis scope.

For astrophotography, it enables you to take exposures of 5 to 10 minutes with a telephoto lens of 200mm focal length or less. However, if you want to take longer exposures than 10 minutes or use a telephoto lens of longer focal length than 200mm, more precise polar alignment is required. The following method of polar adjustment will be done by watching the movement of a bright star in the eyepiece and it is called drift alignment. 1 2 Drift Alignment in the Northern Hemisphere Align the mount to the north celestial pole by using the polar axis scope. This will save time during the process of drift alignment. Align the Mount in Azimuth Prepare an eyepiece with illuminated reticle (cross hairs) or such as the Vixen OR12.5mm with illuminated reticle. Choose a bright star near the celestial equator and near the meridian, and put it in the filed of view of the eyepiece. Turn off the power switch of the mount momentarily while looking into the eyepiece to see which direction the star moves. Confirm the west and rotate the eyepiece so that one of the cross hairs is parallel to the east-west direction in the field of view. The figure on the right shows the directions of north, south, east and west in the eyepiece according to a type of your telescope with or without a star diagonal.

Drive the mount at sidereal rate and look into the eyepiece to monitor the drift motion of the star in the north-south direction. If the star drifts north (i.e. moves down due to inverted view), move the mount to east in azimuth. If the star drifts south (i.e. moves up due to inverted view), move the mount to west in azimuth. Adjust the mount with the azimuth adjustment screws. Make appropriate adjustments to the polar axis to eliminate the drift. Align the Mount in Altitude Choose a bright star near celestial equator in east but not too low, and put it in the filed of view of the eyepiece. Turn off the power switch of the mount momentarily while looking into the eyepiece to see in which direction the star moves.

If the star drifts south (i.e. moves toward the lower left due to inverted view), move the mount to low in altitude. If the star drifts north (i.e. moves toward the upper right to inverted view), move the mount to high in altitude. Adjust the mount with the altitude adjustment screws. Make appropriate adjustments to the polar axis to eliminate the drift. 26 APPLICATION Drift Alignment in the Southern Hemisphere Align the mount to the south celestial pole by using the polar axis scope. It will save you a lot of time in the process of drift alignment. 1 Align the Mount in Azimuth Prepare an eyepiece with illuminated reticle (cross hairs) or such as the Vixen OR12.5mm with illuminated reticle. Choose a bright star near the celestial equator and near the meridian, and put it in the filed of view of the eyepiece. Turn off the power switch of the mount momentarily while looking into the eyepiece to see which direction the star moves. Confirm the west and rotate the eyepiece so that one of the cross hairs is parallel to the east-west direction in the field of view. The following descriptions are based on a telescope without a star diagonal. Drive the mount at sidereal rate and look into the eyepiece to monitor the drift motion of the star in the north-south direction. If the star drifts south (i.e. moves down due to inverted view), move the mount to east in azimuth. If the star drifts north (i.e. moves up due to inverted view), move the mount to west in azimuth. Adjust the mount with the azimuth adjustment screws. Make appropriate adjustments to the polar axis to eliminate the drift. 2 Align the Mount in Altitude Choose a bright star in east but not too low, and put it in the filed of view of the eyepiece. Turn off the power switch of the mount momentarily while looking into the eyepiece to see in which direction the star moves. Confirm the west and rotate the eyepiece so that one of the cross hairs is parallel to the east-west direction in the field of view. The following descriptions are based on a telescope without a star diagonal. Drive the mount at sidereal rate and look into the eyepiece to monitor a drift motion of the star in the north-south direction. If the star drifts south (i.e. moves toward the lower left due to inverted view), move the mount to low in altitude. If the star drifts north (i.e. moves toward the upper right to inverted view), move the mount to high in altitude. Adjust the mount with the altitude adjustment screws. Make appropriate adjustments to the polar axis to eliminate the drift. Change the Altitude Setting The SX2 mount is set for use in the middle latitude zone (latitude of 35 degrees plus/minus 15 degrees) at Vixen’s factory. If your observing site is lower or higher than the range of the middle latitude zone, you need to change the current altitude setting to match the latitude of your observing site. The range of altitude adjustments is divided into three positions (low, middle and high) between 0 degrees and 70 degrees in latitude. 1 2 3 4 Remove the optical tube and the counterweights from the mount. High Latitude : 40 degrees up to 70 degrees Middle Latitude : 20 degrees up to 40 degrees Low latitude: 0 d e g r e e up to 30 degrees Loosen the altitude clamp lever on one side of the mount body where no altitude scale is attached, and turn the altitude adjustment knob so that the altitude of the mount comes to a position of 35 degrees. Then, tighten the altitude clamp lever. Loosen the bolt beneath the altitude clamp 2 lever with the 5mm Allen wrench and 3 remove it.

Slew VariSpd Star N X3.0 Backlash X 00 This manual describes the setting of RA first, but you can start from either direction, RA or DEC. Pressing the up or down key will increase or decrease the value by 10 increments and pressing the plus or minus button will increase or decrease by one increment. compensation are available between 0 and 99 both in RA and DEC. 31 The values for the backlash Backlash Y 00 APPLICATION 6 Press the Mount button to make the direction keys available. Confirm the amount of backlash in the direction of RA. Guide star Center the star in the field of view of your eyepiece and watch how the star moves while pressing the left direction key. Keep pressing the direction key until the star begins to move. Next, press the right direction key to watch how the star moves in the field of view. If there is a time lag and the star does not begin to move instantly toward the direction you press, a value for the backlash compensation is set too small (weak) or set to “0”. If the star begins to move quickly and largely at the same time you press, a value for the backlash compensation is set too big (strong). 7 Confirm the amount of backlash in the direction of DEC in the same way using the left and right keys. Tips on Backlash Compensation Setting Watch how the telescope moves when you increase the value. Start with setting an initial reference value (10 for example), and double this value after checking the telescope movement with the initial value. If the second value (= 20) is too small to compensate for the backlash, enter the number doubled (= 40) as the second value. necessary. Likewise increase the number by doubling the value if Example: Enter 20 for the backlash compensation. If this value is too small for the compensation, increase the value to 40. If it generates too much compensation as a result, decrease to the value halfway between 20 and 40. If the value of 30 is still somewhat bigger for the compensation, decrease to 25. On the contrary, if 30 is somewhat small, increase to 35. In this way you can adjust the mount for the most effective backlash compensation. Backlash compensation is not compatible with an autoguider in most cases. Set the values to “0” in RA and DEC when you use the autoguider. 32 APPLICATION Setting for Autoguider T he STAR B O OK ONE c an b e us e d for auto gui ding in c on junc tion with an ex ter nal auto gui ding sys tem that is c ompatible with the SBIG auto gui der.
