Just to add more information to this flattener thread, it has a 2" thread on the telescope side so you can screw filters on it.

Looking at the entry for the rotator at First Light Optics it is

"Only fully compatible with the Evostar-72ED OTA (shortened tube version) shipped from December 2019. Earlier versions of the telescope may not reach focus with some cameras when using the rotator."

Do we know which cameras, or which makes of camera? 

I can't find anything about a new version?

That's news to me. So now they have shortened the 72ED, apart from the tube being shortened have they changed anything else, may I ask?

However it does work with an OVL Flattener.

From memory (it’s Sunday) Synta/Sky-Watcher shortened the OTA length 10mm to make it easier to use their rotator with DSLR cameras. They said that was the only change made to the design.

HTH,

I received my rotator almost a month ago and it fitted perfectly with the OVL flattener. You need to unscrew the beveled part of the flattener. That's it.

Here it is a photo of the fitting. Hope this helps

Hi @fozzybear

I've just rotated it counterclockwise like any other thread.

If it is rock solid in your case maybe you will need to use some tricks.

Apply some heat near the thread with a lighter and then, with a thick cloth in your hand try to unscrew it. You could also use WD-40 but that could spill over the lens and maybe damage the coating.

No other ideas for that.

well managed to free the bevelled section it was really stuck on. Solution a little hot water to cover the bevelled section in a tray and left the FF for a couple of minutes in it's bath a pair of rubber gloves and hey presto she succumbed and gave in (maybe a little adhesive applied in production)

Anyone tried this with the StellaMira 2" Field Flattener as I believe it's identical to the ovl field flattener ! ? Any way I've ordered the rotator and will update later this week.

And yes that bevelled section is really stuck on ! Gonna soak it in hot water as suggested !

Ordered a rubber wrench thing now as it's not shifting and it definitely comes off as if you look inside there's further threads behind the bezel !

Update.

Got it off by screwing the nose piece into the bezel really tight then unscrewing it and the bezel came off with it, it screws into the rotator now but the threads aren't brilliant but it's tight so I'm happy.

mine was the same so maybe the pitch of the thread is different but mine went on the same as yours

So to rotate the camera you undo the two thumbscrews on the rotator and then rotate? What's the difference then in just undoing the thumbscrews on the telescope and rotating the field flattener? Unless I am missing something??
