1.1.7.  Attaching the optional camera lens adapter 

 

The optional camera lens adapter may be used instead of the 2” nosepiece if you wish to use any 

Nikon 35mm camera lens to take wide field images with 
one of the large format cameras.  For example, using the 
popular Nikon 300mm F/2.8 lens 
on an STL-11000M camera will 
give a field of view of nearly 5 x 7 
degrees.   A standard 50mm lens 
will give a field of view of 28 x 41 
degrees!  The camera lens adapter 
is attached to the camera by 
screwing the threaded barrel of the 
lens adapter into the large threaded aperture of the 
accessory mounting plate.  A locking ring is provided on 

the threaded barrel to hold the adapter in place after 
adjusting it for best focus at infinity.  
 

Caution:  

In order to achieve the low profile needed for 

the Nikon adapter, the small locking pin and release 
lever have not been used in this adapter design.   We 
have found that the lens fit is snug enough that it will 
not move by itself once it is screwed into the adapter 
ring.  However, care should be taken that you do not 
inadvertently rotate the lens in the adapter while 
adjusting the focus.  This will cause a shift in focus and 
may leave the lens loose in the adapter.

  

1.1.8.  Connecting the STL-RC Adapter and Relay Cable 

 

The camera contains internal electronic (TTL) relays used to control a telescope during self-guiding 
or when auto guiding.  Most modern telescope drive controllers have a 6 pin modular phone style 

jack on their front panel or hand paddle for plugging in an 
autoguider.  The relay outputs from the camera are brought out via a 
DB9 connector labeled “AO/SCOPE.”  The 
same connector will also be used to control 
an Adaptive Optics device similar to the 
AO-7 (Note:  The AO-7 cannot be used 
with the Research Series Cameras).  To 
connect the telephone style Relay Cable to 
the camera, use the STL-RC adapter 
(shown above) to make the connection between the 6-pin RJ11 plug 

on the cable and the 9 pin plug on the camera.   Plug the other end of the Relay Cable into the CCD 
or Autoguider port on your telescope’s drive corrector.
