I purchased a second hand Skywatcher 120ED Pro. Its the gold colored one and the focuser has been changed to an Antares Crayford.

I've been using it for imaging and bought the .85x Orion Reducer/Corrector that is made for this scope. However, its made to screw on the draw tube while the Antares Crayford requires a push type.

There are adapters made for this that are available in Europe but I haven't had any luck getting them to ship to North America. Also, I haven't found any adapters in North America. However, there are some that convert SCT threads to push type.

So, does anyone that own this type of scope and know if the threads are SCT size or, if not, where I can get an adapter in North America to convert them to push type?

I have skywatcher evostar 120. I use it with it's stock focuser and it has M57 thread which i have used to attach baader clicklock ( http://www.teleskop-...aader-2--Cli... ). I suppose that the reducer attaches using this same thread so you need to find proper adapters from M57 to the thread that you have. See some of the adapters at Telescope service which will maybe work ok:

Unfortunately i am not sure if they ship to united states.

Thanks Neptun2, I appreciate the information. Seems to be a choice of adapters in Europe but nothing in Canada or the U.S. I'll check more in North America now that I know the threads are M57. If there is nothing, I'll keep trying in Europe. Thanks again.

I just bought one of the adapters from teleskop express, not cheap after all said and done. Not many options though...

Any way to figure out what the thread is on the reducer and have a thread adapter made to convert reducer to say a T thread which would allow many options to attach to 2" tube?

Yes Skywolf856, getting an adapter made is a good idea. Neptun2 pointed out the threads are M57, so that's what I would need to adapt to something I could attach to a 2" barrel. Unfortunately, I am in the middle of nowhere with no shops nearby. I'll have to find someone on-line. I'm still surprised that these scopes - including Orion and Celestron versions - in 80mm, 100mm and 120mm are fairly popular in North America without any adapters available. However in Europe, you have a choice of vendors. I still wonder if I've missed something obvious.

Have you considered checking with a local machine shop?

Yes Tom, but as I mentioned in my previous post, I'm really in the middle of nowhere with no local shops. So, I will try when I go to the city in a few weeks, or maybe I'll get an answer from one of the European companies.

For anyone else who searching for this adapter, First Light Optics - in England - is now shipping to North America. They had the most reasonable price and its very well made.

I am not offering to make one as at this time as I can not make one, but is it possible that one of your friends knows a friend with a lathe? The reason at the moment is I have a new lathe and I have not attempted metric on it as of yet.

Thanks Pierre but I have just received one from FLO, so I'm fine now.

Hello TimN.
I'm from Toronto Ontario too.
Also planning to buy the same Gold tube
Sky Watcher 120 ED.

I am aware that the standard focuser that
comes with it is a single speed.
Is it possible for me to upgrade the focuser
to a dual speed

Thank you very much.

Conrad

Skyward Eyes, the vender that handles the USA sales has highly recommended the Feathertouch 2" with 2.5" tube from Starlight Instruments. See the Sky Watcher Pro 80ED Focuser topic in this section of the forums.

If you need a focuser to handle many of today heavy imaging accessories the 2" Feather Touch with the 2.5" draw tube is my recommendation. This is the longest draw tube they produce in a 2" format. If you need more focus travel extenders can always be used.

Thank you very much for all the response guys.
I will definitely consider the 2" Feather Touch focuser.

I have the 120 ED gold tube Skywatcher and I equipped mine with a Black Moonlite focuser.
Wonderful scope deserves the Moonlite or Feathertouch!

Thank you Tony,
I am saving for a Moonlite focuser now.
Very nice to hear that from a very experienced astronomer like you.
And most specially from someone who has the same exact telescope.

Appreciate it much.

I have a gold tube ED120 fitted an older red Moonlite CF2. It's a superb addition to an excellent scope :)

You will not be disappointed !

Tim and all with a 57mm threaded focuser tube. 57mm is the standard thread on all the Borg small telescopes and reducer/flatteners.

If I had read this thread earlier that may have helped you, as Borg has a #7425, 2" nosepiece to M57 thread, and tons of M57 thread adapters.

Astro Hutech's website has all the components and pricing, they are located in California.

Just in case anyone else needs a 57mm threaded component.

Cheers,

Paul
