Hi Guys, I'm new to Iceinspace. I have a DIY question for any one that can help me. I have a 8" GoTo Skywatcher Dob, And I have just got into Astrophotography which I am enjoying greatly. I am building a home observatory with a roll off roof so I can do some imaging at home as I have limited time and I would like to permanently mount my Dob to a pier I have made inside my Observatory so I can leave it set up. And I don't particularly want to spend a $1000+ on a EQ mount so I can stop field rotation. (call me frugal but my funds are limited) .
My scope as you know already has GoTo drive so I was wondering if there is any way I can change the set-up to think it is an EQ drive instead of an AZ? I think that's right:confused2:

I can easily make a wedge to mount the Dob this in no problem at all The thing that is puzzling me is, My friend has a LX200 on a fork mount and when he puts it on a wedge he just changes the setting in the hand controller to the other mode( as far as i'm aware) But mine doesn't have this function.

I hope this all makes sense:confused2:

Any ideas would be great thanks.:help:

You could build a eq platform, its about the best option for dobs. As for a wedge i don't think thats possible, because once you put it on a angle the drive wouldn't be able to move it because of it not being balanced. Have a test and see just with a wedge in place, you will see what i mean. There's to much stress on the az motion and they arnt made to run that way, your putting a new force in the mix.

Lol maybe someone has came up with something to offset goto using a eq platform now that would be sweet.
