Thanks John,
The collimation is as good as I can get it. Maybe not perfect, but it must be pretty close. I find the mirror in the 12" is very heavy and so causes some movement (even with the replaced springs) so I check the collimation throughout the night just in case its shifted...
I was wondering if it was the speed of the scope causing this effect. I bought these EPs when I had a SCT, and with a F stop of 10 they worked a treat. So I collected a fairly complete set, especially as a wide FOV is an advantage on a SCT. When I sold the SCT I decided to keep the EPs as they were/are a good quality set...
Now I have a nice fast scope, and all my good eps are no longer suitable!!! Brings you to tears.... especially when my fallback position in EPs is not so good.
BTW I am located in Sydney.
Thanks for the help.
Michael
