Does someone know the optimal backfocus length for the LS6 ?

 

Thanks

Francois,

 

I did a little checking.  Optimum back focus is not a spec that Meade publishes.  Any image error due to not having the focus at that exact spot is small compared to the effects of seeing or any tracking errors.

 

Hope this helps,
