Bo,
I did not mean to offend you with my comments, and there was definately no offence taken here. I know from a newbie perspective that aperature can be difficult for some to understand, so I understand and agree with what you said.
When we bought the se4 was still deciding, the choice was this or a dob. When we were told that we could see the HH then the decision was made. Maybe not enough research on my behalf, I do not know. As we have a caravan and go camping then we decided it could work for us, although limited.
In regard of the mounts, I am suspecting with the amount of reading I have done that I am now confusing myself. A standard Dob as seen here
http://www.bintel.com.au/Telescopes/...3/catmenu.aspx is a AZ mount? So when they set them up they need to be set for polar alignment i believe. For the goto, to upgrade a standard you need Argo Navis and Servocat to create a goto. Using Argo Navis just gives you a "push to" is that correct.
As for those SDM Scopes, that is some very serious aperature there. They are awesome.
I hope that I am not boring you with all of the questions but I am learning a lot from this, and I thank you.
Cheers
Andrew
