I've installed the Celestron motorized focuser on my Edge HD8.  With it attached, the balance point for Dec axis is very different.  It seems to me that I need a counter weight opposite the focuser on the other side of the handle.  Has anyone else dealt with this and come up with a solution?

 

Thanks,

 

Howard

What mount are you using?

 

I have an Evolution with a fully loaded OTA (Starsense and RACI illuminated finderscope) including camera and Hyperstar and MKIT20 focusser/motor. It is seriously unbalanced but works great. If anything the front end loading helps tracking etc.  Depends on mount, but you might be worrying unnecessarily.

I haven't yet considered trying to offset it, but it definitely does cause some imbalance on the DEC axis. The big question is whether that is sufficient to effect image quality.

I have a NEQ6 Mount. And actually I mostly have to deal with my RA guiding being larger than my Dec guiding. My Dec guiding is typically pretty stable. I haven’t actually done any Astrophotography with the focuser attached yet however. The imbalance is just very noticeable.

I use adhesive backed wheel weights for balance.

Stan,

 

Are these "wheel weights" for cars?  I'm not familiar with them.  Can you point me to a link showing what they look like?

I found them online.  Thanks!
