Part II: Getting Started 

 

Frequently Asked Questions about the packaging: 

Doesn’t an astrograph deserve a better box than just a simple cardboard box? 

Yes, indeed. But when we asked seasoned astrophotographers what type of box should be 
the best for a Newtonian astrograph, the answer was always the same: “

Only a box I choose 

specifically for my equipment will do the job

”. 

Because every astrophotographer we met has his own choice of camera, filter set, accessory 
plate or even car trunk dimension we decide to let the customer free to choose what will be 
the  best  fit  instead  of  asking  added  money  for  a  nice  box  which  a  vast  majority  will  find 
unpractical or even totally useless. 

No eyepiece is provided with my telescope. Is it normal? 

As the Quattro series are fast Newtonian astrograph we were unsure what can be the best 
eyepiece  to  provide.  Seasoned  astrophotographers  use  different  eyepieces  for  different 
purposes:  a standard low magnification eyepiece to check if the object  is inside the field of 
view,  a  high  magnification  eyepiece  to  observe  Moon  details  and  planets,  and  many  more 
usages were evoked. 

Many astrophotographers already have eyepieces at hand so we decide to let any standard 
eyepiece out of the box and to not ask money for an accessory most customers already have 
at hand. 

Why is no coma corrector proposed as standard? 

A  high  quality  coma  corrector  (see  next  paragraph)  is  an  essential  accessory  for  widefield 
astrophotograpy.  But  the  Quattro  series  can  also  offer  nice  visual  images  without  coma 
corrector. 

Again we decide to let the coma corrector out of the box and let  the customer  decide what 
will be the best fit. 

What does Sky-Watcher propose for the Quattro series as accessories? 

If  you  are  looking  for  a  great  eyepiece  to  use  with  your  telescope  or  other  compatible 
accessories,  like  the  F4  Coma  Corrector  (4  lenses,  enlarged  T2  thread),  we  advise  you  to 
ask  your  reseller  or  visit  the  Sky-Watcher  sites  at
