PRIMA LUCE LAB ESATTO 2" ROBOTIC FOCUSER

AstroDave

Bought the 2" Esatto/Arco combination .. Excellent communication and assistance as usual from the team at Testar .. from a Toolmakers perspective Prima Luca components are beautifully made .. design and assembly to my Saxon 102mm scope was straight forward (made a dedicated adapter) camera end was off the shelf spacers etc ... running the setup through N.I.N.A. and everything configured easily and sequences run spot on .. just need less cloudy skies in MELB.

Terrific focuser

This is a terrific focuser. I'm using it with a 9.25 EdgeHD SCT. Not only does it carry a heavy load and allow unattended refocusing during the night but it does a measurably better job than I was ever able to achieve with a bahtinov mask. I use it with a wired usb connection to NINA, as I have never had reliable result with wifi. Note that the Esatto is so precise (small stepsize) that you will need to user a large stepsize in NINA. I started with 1000 and now use 1500. One quibble - you have to intall Primaluce's free astro imaging program to update the firmware, but that took 5 mins and gives you another way to control the focuser, so that's ok. I like this thing so much I have now bought the Esatto 3 upgrade kit for my Esprit 100 - looking forward to trying it out.
