The SPACE LAUNCHER series of telescopes was designed for visual observing.  After looking at the night sky for a while 

you may want to try your hand at photography of it. There are a few simple forms of photography possible with your 
60AZ, and 76AZ telescope for celestial as well as terrestrial pursuits although celestial photography is best 
done using an equatorial mount or computerized altazimuth mount.  Below is just a very brief discussion of some of 
the  methods  of  photography  available  and  suggest  you  search  out  various  books  for  detailed  information  on  the 
subject matter. 
 
As a minimum you will need a digital camera or a 35mm SLR camera.  Attach your camera to the telescope with: 

Digital camera – you will need the A focal Camera Support  Adapter (# 01110).  The adapter allows the 

 

be mounted rigidly for terrestrial as well as prime focus astrophotography. 

camera to 

 

35mm  SLR  camera  –  you  will  need  to  remove  your  lens  from  the  camera  and  attach  a  T-Ring  for  your 
specific camera brand.  Then, you will need a T-Adapter 

 

(# 01102) to attach on one end to the T-Ring (# 01103) and 

the other end to the telescope focus tube. Your telescope is now the camera lens.

Short exposure prime focus photography is the best way to begin imaging celestial objects.  It is done by attaching 
your camera to the telescope as described in the paragraph above.  A couple of points to keep in mind: 

 

You  can  image  the  Moon  as  well  as  the  brighter  planet s  with  very  short  exposures.   You  will  have  to 
experiment with various settings and exposure times.  Much information can be obtained from your camera 
instruction manual which can supplement what you can find in detailed books on the subject matter. 

 

Do your photography from a dark sky observing site if possible. 

 

Remember, this is just very simple photography.  Fo r more detailed and serious astrophotography you need 
an equatorial mount or a computerized altazimuth mount.

During the last few years a new technology has evolved which makes taking superb images of the planets and moon 
relatively easy and the results are truly amazing.

Special  cameras  have  been  developed  for  taking  images  of  deep  sky  images.   These  have  evolved  over  the  last 
several years to become much more economical and amateurs can take fantastic images.  Several books have been 
written on how to get the best images possible.  The techno logy continues to  evolve with  better and easier to use 
products on the market.

Your telescope makes an excellent telephoto lens for terrestrial (land) photography.  You can take images of various 
scenic views, wildlife, nature, and just about anything.  Yo u will have to experiment with focusing, speeds, etc. to 
get the best image desired.  You can adapt your camera per the instructions at the top of this page.
