sw low profile focusser query

[sunshine185]

ATM I just have the standard focusser that comes with the scope, the ep is approx 65mm away from the tube when the focusser is racked right in. if I bought a sw low profile focusser, how much more inward travel would I get? I thought about moving the primary up the tube but this seems a bit out of my depth. Any help greatly appreciated.

I will measure mine later on and post the info here

Cheers! I asked a supplier who said I wouldn't get any more "inward travel" by using a low profile one as he said they are about the same as the standard ones, they were made to replace the old style focuser which was a lot bigger. Just wanna make sure before I bought one

Hi info as requested, dimensions are in mm taken from top of adaptor plate (non standard) to top of focuser tube

42mm

67mm

110mm

So, when the focusser is all the way in it measures 42mm, that's a good 23mm further in than mine does. Many thanks for your help, much appreciated.

P.s. that also looks to be a better quality focusser, seems to be a good, possible upgrade for me.
