Hi, Thanks for the reply and sorry for the confusing post here
I was actually referring to the imaging/ guiding ratio that is found on the astronomy.tools page
I was just trying to find out if this figure of 1:0.77 is poor.
I think i read somewhere that a scale of 1:3 would be ideal
I currently have an Orion 60mm guide scope attached and the scale is 1:3.37
So was just basically trying to find out of moving to an OAG with this 1:0.77 is going to work or not.
Hope that makes sense?
Any advice is appreciated.
Thanks.
Peter.
