Focuser placement decisions

Posted by maphilli14 on January 23, 2011 at 8:27 PM

 

checking NEWT often and looking at finding balance between photography and visual, I stumbled across this:

So I arrived at 2 values in my calculations for visual and photography, I split the difference in the focuser placement.  Since it's a sonotube with a backup half untouched, I feel comfortable making some more cuts!  :)


 

46” Mirror face to focuser is the new value and 55” seems like a nice tube length?! Let's see....

 


Photos pending!
