thanks for the answer..

i dont want to plug in a Guiderfield, that is now problem.

I want to show my second camera into the same view.

My first camera have 5472 x 3648 Pixel and 6.58 my Pixel.
The Second camera have  3362  x 2504 Pixel and 5,4 my Pixel.

I have too try it to modify a Guiderfiled from the Sbig ST10XME, but it dont goes.

Any Idea ?

They definitely don’t have to be centered on the same poin t– mine were about two degrees off in RA and half a degree in Dec and I got it to work.

I think you have to set up the second camera as the guiding camera only with a bigger field and if both are centered to each other with no offset!

There is definitely a way to do this – I used to do it for my guide camera at the same time as my imaging camera.

Do I remember how to do it? Sorry, I do not. Hopefully somebody else does.

Hello Users :)


I have a question:


Iám working with two camears on two diffrent teleskopes.


first Scope Newton 1186mm with Canon Eos 6D Fullframe


second Scope C11 HyperStar with Moravian G2-8300 CCD


I have put the two cameras into the Guide CCDs.nad :


Canon Eos 6D                Cmos        6.58    6.58  5472  3648  1 

G2-8300                          Kaf8300     5.4      5.4   3362  2504    3 


works fine, if i want to show one camera.


But i want too see the two CCD Fields at overlay into Guide, because i work with the two telecopes at ones.


Is there a way to do this ?
