*In the preceding chart, a question mark represents a question that needs to be asked of the customer regarding their equipment.
Other information that is required or is unique to the telescope or mount is also listed. In all cases we need to know the
manufacturer and model of telescope and/or mount.
For encoder and hardware (ENC) and hardware only (HDW) orders, please also ask the customer which computer they have or will
be using. With this information we can provide a computer holder that will fit their computer (see the chart below). If they do not
know or do not specify which computer they have, we will not include a holder.

†Part numbers have two sections, the first represents the type of equipment being purchased and the second represents the type of
equipment the customer owns. The first section will be one of the following: NGC, MIN, MIC, SGT, ENC or HDW. The second
portion will come from the last column in the chart above. For example, an NGC-microMAX complete system for an Obsession
would have the part number MICOBS.
SUP = NGC-superMAX System SGT = SGT-MAX System (Software Guided Telescope)
NGC = NGC-MAX System ENC = Encoders and Hardware Only
MIC = NGC-microMAX System HDW = Hardware Only

9The Losmandy mount must have a flat (or a groove on some early GM8 mounts) machined into both the Right Ascension and
Declination shafts. Losmandy stopped machining flats in the shafts in 2002.
10 In order to supply encoder hardware for the fork mounted Celestron C8 telescope, we need to have information about the right
ascension axis center screw hole. Generally we can guess at this information based on the date of manufacture. However, there
were great variations and inconsistencies in the manufacturing specifications from inception through 1985. The more information
you can provide us, the more likely we will be able to provide the correct main gear for the right ascension axis. Use the following
as a guide, remembering that we have seen exceptions to almost every bit of information listed below.
If the C8 was manufactured after 1985:
The optical tube will be black.
The right ascension axis center screw hole will have a 10-32 thread.
If the C8 was manufactured between 1980 and 1985:
The optical tube will be orange or black.
The right ascension axis center screw hole will have a 10-32 thread in most cases but it will have an 8-32 thread in a few cases.
If the C8 was manufactured between 1975 and 1980:
The optical tube will be orange.
The right ascension axis center screw hole will have an 8-32 thread.
If the C8 was manufactured before 1975:
The optical tube will be orange.
If there is no hole in the center of the right ascension axis it will need to be drilled.
If the center hole is not threaded it will need to be tapped (to JMI specifications).
If the hole is threaded we will need to know the thread size. Check the declination thread size also. Some scopes have non-
standard 10-24 threads on both axes.
We also need to know the inside diameter and depth of the right ascension screw well. When measuring the depth, include any
ribs that protrude up from the surface. Placing a straight edge (such as a ruler) across the top of the hole will help in making
this measurement.
We may need more specific information such as drawings and dimensions.
Please note that the fork mounted C8 is not the same as the Ultima 8, Celestar 8, Celestar 8 Deluxe, Fastar 8 or any German
equatorially mounted C8 which all require different hardware.
The C8 Powerstar PEC, with the central right ascension locking knob, needs some special consideration. This telescope was
built for encoders but included a flaw in the design. The clock drive movement is not registered by the encoders. This leaves
two options with both having drawbacks that must be considered. The first option is to use the MAX computer's ET (equatorial
table) mode since normal R. A. tracking will not be seen by the encoders. The drawback here is that the telescope must be
polar aligned for the encoder system to work properly. The second option is to use EQ mode and turn off the telescopes clock
drive. With this option, the scope does not need to be polar aligned. The drawback is that the telescope will not be able to
track in right ascension.
