into an overhead luggage compartment, but you still have to be able to lift it u

that high! You must also be aware of all rules and regulations regarding weight

limits and allowable case sizes, not to mention potential security problems.

Please do your homework before trying to take a trip with your valuable

astronomical equipment. We have designed the mount to be portable, but we

cannot guarantee that you will be allowed to carry it with you.

One final caution: This is a “really cool” feature, but remember, you will need to

remove the mounting plate to take advantage of this capability. It will be great

for long-distance travel, but you may not want to store the shaft inside the dec

axis for trips to and from your favorite local dark site.

Attach Mounting Rings

(purchased separately)

Flat and ribbed plates: constructed with keyhole slots at the location where your mounting rings attach. This feature

enables you to partially loosen the screws on your rings just enough to insert them into the larger part of the keyhole, then

slide the rings to the narrow part and tighten them with a hex key. You can even accomplish this with the rings on the scope,

although this maneuver may be difficult to accomplish with a large, heavy instrument.

We prefer this keyhole method to the standard way of completely removing the screws and possibly dropping them in the

grass.

Astro-Physics or Losmandy Dovetail Plates: Attach the mounting rings to the male dovetail plate (sliding bar).

Fine Polar Alignment

For casual observation, you may skip most of this section and simply start observing. Don’t forget to tighten your ALTITUDE

LOCKING LEVER and AZIMUTH LOCK KNOBS and make sure both of your AZIMUTH ADJUSTER KNOBS are snugged against the

ZIMUTH ADJUSTING PIN. Move the telescope manually or by using the N-S-E-W buttons of the keypad. The keypad and

GTO Servo Control Box will function as soon as they are plugged in. That means that the R.A. axis will be tracking up to the

limits of your polar alignment. However, if you plan to use any of the go-to functions of the Mach1GTO or do

astrophotography, you must perform a more accurate polar alignment.

Methods for fine polar alignment

• Polar Alignment Scope – Use our optional polar scope

[PASILL4 or PASILL3 (prior version)] models – earlier polar

alignment scopes cannot be used as effectively with the

Mach1GTO as explained later in this section). This will

allow you to quickly align your mount on the pole stars. The

reticle was designed for use in both the Northern and

Southern hemispheres. Even users of the GTO

computerized mounts will find these polar scopes useful,

particularly if your telescope is not orthogonal to the mount

(please refer to the keypad manual for a discussion of

orthogonality). If you have a PASILL4 or PASILL3, please

read the instructions sheets that came with it with the

following modification:

The reason that the Mach1GTO requires either the

PASILL4 or PASILL3, is that these polar scopes have

reticle housings that turn freely in their collars. Unlike all

the other mounts that we have produced since the early

1990’s, the Mach1GTO’s polar axis shaft does not reach all

the way to the bottom of the polar axis housing. With these

other mounts, the polar scope was actually screwed into

the end of the polar axis shaft. If you turned the polar (RA)

axis, the polar scope turned as well. With the Mach1GTO,

the polar scope attaches to the Polar Scope Adapter, which

is, in turn, attached to the polar axis housing, not the polar

shaft. Turning the polar axis does NOT also turn the polar

scope. To use the polar scope with your Mach1GTO, simply turn the polar scope’s reticle housing instead of the

RA axis as instructed during the final stages of polar alignment. If you started with the reticle properly oriented

these will be small movements.
