How to use!ESATTO as focuser for!refractors
ESATTO#is available in different diameters and you have to choose the one that better fits your telescope based on
your refractor specifications. If a compact refractor may use a standard 2" focuser, a larger refractor may need for
the ESATTO 3". ESATTO is designed to be used as new focuser for refractors, by replacing your standard focuser.
So you can#remove the original focuser from the tube of your refractor and connect the ESATTO. In order to make
this as easy and straightforward#as possible,##we designed different adapters: first of all you connect#the adapter#to
the tube of your telescope and then you connect the ESATTO robotic microfocuser.
PL3600230 adapter allows you to easily install ESATTO on the Skywatcher EVOSTAR 80 ED telescope.
Please note, if your#refractor telescope has a built in corrector (field flattener or reducer), in order to use ESATTO
first of all you have to check if the corrector is inserted in the focuser's draw tube or if it's separated from it. If the
corrector is built in in the#draw tube, by removing the original focuser you will remove the corrector too and in this
case you can't use the ESATTO. If your corrector is separated from the focuser (for example, like the Borg 90FL
f3.9 and 107FL f3.9, the Takahashi FSQ85 or one of the many 65mm quadruplets available with different brand
names), you can use the ESATTO as new focuser for refractor.
iI the refractor's corrector (at the center in the image above) is separated from the standard focuser (right in the
image above) you can use ESATTO.
