ZWO EAF on Skywatcher Evolux 62ED

I tried to do this but had all sorts of trouble. First I had to modify a coupler to get it to fit in the housing on the scope. After that it took all kinds of tinkering to balance the whole thing (EAF, ASIAir, guidescope+cam) on a SW SA Gti. After all that trouble I didn't get it to work properly, the focuser just somehow got too stiff and the EAF wasn't able to move it. It was over -23 C outside so maybe that had something to do with it. I didn't feel like wasting more time on it when I had the clear skies, so I just took it off and focused with a bahtinov mask. After that initial focusing the scope held focus like a champ the whole week I imaged (didn't take the rig inside during daytime) so at least in my case the EAF isn't really needed. I did all rest of the sessions during that winter without EAF on this rig as well. Once the scope is acclimated, I focus once and that's it. 

The focuser mechanics on this scope aren't that great so I don't think it's worth the hassle, at least for me. Even if I could get it to function, the focuser may not be precise enough to give repeatable results with the EAF.

I received the scope today.  I got the EAF for my Samyang 135 because I found it hard to focus but the microfocuser on the 62ED is quite smooth, I think I will try it for a while before adding the EAF.

I am happy with my purchase but there's 2 things I really dislike with it.    First, the cap doesn't stay in place, it had already fell 4 times in the first 10 minutes I had the scope.   The second thing is this focuser locking scres shown by the arrow in my 2nd image.  The dovetail bar cannot be moved backward without running into it which I why I had to add a 2nd dovetail bar.   That makes it easy to balance but the lock screw is a little hard to reach now.   I wouldn't have been a deal breaker if I had known but it's a little annoying.

I am happy nonetheless to have my first real telescope althoug it's a small and cheap one.

I had the 62ED for a while and also had to remove the bottom screw in order to install a Pegasus FocusCube2 (which otherwise installed pretty easily, except that I needed to find a longer screw at the hardware store to fasten the bottom plate, IIRC). The focuser seemed to function okay without it.

I wanted to make things easy so I bought a bracket on Etsy made for the 62ed and 82ed.  It comes with everything you need.  It’s no longer available on Etsy but you can find it online.  Here’s one link

It turned out to be a nightmare because it looks like I was sold a scope that had been messed with and returned.  The tiny hex screw that holds the know was stripped and the hex key wouldn’t grab so I had to drill it.

Then once the eaf was installed the focuser sagged a lot.  See this topic

i was able to fix it by tightening some of the screws but it’s not straight and my stars aren’t round.

I haven't had a chance to work on it since but other adjustment screws look like they are stopped too.

I don’t know I just use the one that came with the kit.

I did the same thing. My measurements of the hole in the housing was 17.86 mm and I got the other end of the coupler down to 17.56 mm and then it fit. But yeah, it is approximately 18 mm and if you can get the coupler down closer to 17 mm that'll be fine. The closest one I found was 19 mm so it took a while. I attached the coupler to cordless drill and ground it against coarse sand paper. Whatever works!

But that is as far as I got last winter. I had some problems with it which I didn't have time to troubleshoot, so I took the EAF off and focused manually. I might try it again before the autumn season begins though if I can get it working.

Hi, just seen this thread. I have the same combination. I didn't have a need to shave down the coupler for the EAF. There is enough play/movement in the focuser spindle to push it through from the course focuser knob side. This was just enough to connect the coupler to without further work. All works fine my only reservation is there is considerable 'slop' in the focus draw tube but this nothing to do with the EAF.
