I am about to order  the 2" model. I need something with no flex in the draw tube. I can use some feedback...plus and minus.

Larger diameter draw tubes tend to have less flexure. A 2.5" is better than a 2" especially if you are imaging - also less chance of vignetting. Go for the largest size that will mate to your draw tube.

I have the Esatto 2" on my ED80 and love it.

No more manual focusing, filter change during he night an everything is in focus.

I had to get an adapter made to connect in to my field flattener and getting the backspacing right, but otherwise great gear.

Luckily I could buy it second hand.

This is my set up on a Mewlon 210 and it has been rock solid, reliable and accurate. All the connections are threaded to keep the imaging train as stiff as possible.

 

Cheers

Thanks for the responses...I am planning to slide an Explore Scientific CC into the draw tube and attach the asi1600 with mini filter wheel via approx. 30mm of spacers to the CC.  I am looking for information on how to set this up with all threaded connections rather than 3 screw lock on draw tube. I know the Esatto is a crayford style focuser. With the load I just described should I be concerned about flexure? Presently I am using a Moonlite CRL which does flex a bit more than I think it should.

I have the Esatto 2” focuser on my 10-inch newt. It has been extremely solid and reliable. The driver software is good.
