This is why ESATTO is the perfect microfocuser also for EdgeHD telescopes

Hi, i can be wrong, but if the focuser is mounted behind the reducer, what about backfocus distance reducer/sensor, shouldn't this be a fixed distance ? In other words should the reducer be mounted behind the Esatto ? Thanks for your response.

I have a new Celestron 800 HD Edge, this focuser will not work with it when the Focal Reducer is installed?

[@EthanJohnston-eg9si]

Can I safely add a ZWo filterwheel, OAG-L, ASI6200 behind the train with the Essato or will that length be too much backfocus?

[@Primalucelab]

It depends on the EdgeHD model you have since 8" has a shorter backfocus than the larger 9.25", 11" and 14". Usually ESATTO 2" if fine with EdgeHD 9.25", 11" and 14 while for the compact EdgeHD 8" we suggest the ESATTO 2" LP (Low Profile) version.

I have skywatcher 200PDS, can i use ESATTO 3"? My telescope has 2" focuser.

[@peterkennett33]

Which OAG and Filter Wheel do you use that will fit properly? I tried the ZWO OAG and the Primalucelab M56-M48 adapter prevented the OAG camera from reaching focus. The stop-ring kept hitting the guide camera and so I could not move the guide camera low enough.

Love the person who asks all the questions! If I understand correctly, you can just put the focusser after the focal reducer and work with the same backfocus as compared to without the focusser. Is that correct?

[@Primalucelab]

That’s correct! You can install ESATTO after the focal reducer. 👍

@@Primalucelab ok great. And should I keep the 105mm FL backfocus? Gracie mille

What is the red box on the top of telescope ? Some computer with wifi antenna ?

Hello, that's our EAGLE control unit for remote control and power of any telescope: www.primalucelab.com/astronomy/computer-and-software/eagle4-advanced-control-unit-for-telescopes-and-astrophotography.html

@@Primalucelab Quite expensive thing. I own the Odroid N2 computer and need a powered box with ports. Your Eagle unit box looks great.

(Projecting my voice into the presenter's head in a strong Italian accent) I've seen a cloudy night's forum complaining of reflections from the Esatto 2 with a full frame camera. The suggestion from PrimaLuce was to use the 3 inch focuser. Is there an adapter?
