Note1: These knobs will fit most 2005 and later C8
models that have black Phillips factory
collimation screws. This includes the
C8 Fastar with black
Phillips factory collimation screws. Do not use these knobs on the 8
inch EdgeHD OTA; this model requires different knobs. |
| Note 2: Most models with black Phillips factory collimation screws require C8 metric knobs.
A few post-2005 scopes have black Phillips collimation screws with standard
threads. Here are some hints to help determine which screws your telescope
has. Make sure the knob threads match
the factory screw threads before installing the knobs. More
information is in our Celestron
technical paper. |
| Note3: The factory dust cover will
fit normally with Bob's Knobs installed. |
| Note4: Some telescope versions have
a small plastic cover over the factory collimation screws. This cover must
be removed and set aside when Bob's Knobs are installed. The cover is
cosmetic only and will not affect operation of the scope. |
