M54 adapter problem

[don4l]

I'm trying to get a 2" nosepiece onto the front of my camera.  I currently have a M54 x 0.75 male thread on the face of the camera.  I also have an old 2" nosepiece which also has a m54 male thread.  So I'm looking for  a M54 x 0.75 Female - Female adapter  ( or a threaded tube might be a simpler description).

I cannot find it anywhere on the internet.

Does anyone know where I can find one?

A 2" nosepiece with a female thread would do, but I cannot find that either.

I'm hoping that someone will tell me that my internet searching skills are lacking!!!

Bit round about way of working it out but think it would work.

Perhaps one of these M54 to T2 adapters then a T2 to T2 female connector then just use a T2 - 2” nosepiece.

edit - thats male to female. 
 

You could buy the 8mm version and cut off the male part , or go with johns idea!

 

Basically you need this

So close....   Unfortunately they are all male-female.  I need F-F.  You would think that it was easy.....

Yeah I edited my post after I noticed the mistake.  Like everything in this hobby - either expensive or compromises.

So frustrating when you just want a simple adapter. Found a US company that could make one up but you’d be looking at about £150.00.or more imported. 🙀🤬

If that T2 extender was available as M54, then I would be in business!

I'm already resigned to needing two "bits".  I've already got 6 (yes 6) 2" nosepieces, only one of which will ever be used in the future!   This is madness!

One of the nosepieces has an adapter to a male 42mm (T2?) thread.  So, I will see if I can find a Female 42mm to Female 54mm adapter.

Might be worth contacting Telescope Express and ask them if they could make up an adapter for you.

This is to image at F8 on the Tak.  I'm not sure that I will do it very often, so it seems a bit silly to spend too much. 

My plans for longer focal length are up in the air at the moment.  I used a Tal200 earlier in the spring, and I got on much better with it than I expected.  However, I do need to do a bit more playing around before I settle on anything.

Why didn't I think of that?

As it happens, I bought the camera from them.  I also ended up exchanging e-mails with the owner.

I'll send him ane-mail in the morning.  I'll report back.  Thank you!

If you ask nicely Wolfi can be very helpfull.

If that thread goes the whole way through, then I would only need one of them!

It's a pity that you cannot phone FLO.

OK l have the sx filter wheel with this type of adapter the thread is 6mm in length on mine, guess just the one would work!

Have you tried SRB PHOTOGRAPHIC  in Dunstable. They used to make 1 offs of adaptors to customer specs.

I've had a look at their website.  At the moment, @whipdry's suggestion looks good - something off the shelf is less likely to be problematical. I'm going to measure up and have a close look tonight.  I have a feeling that 6mm will be all I need.

I have measured things up and I would prefer 8-10mm of thread.  6mm would probably work, but .....

I called SRB, and they quoted me a very reasonable price, but they are very busy at the moment, and it will take 3-4 weeks.  I'm going to have a closer look tonight at my bits to try to figure out how 6mm would work. 

[johninderby]

I just ordered a custom made adapter from Telescope Express to adapt a focuser to a scope. Expensive ar €85 but no alterative really as it’s one of their focusers with a non standard size fitting. Will take three weeks or more. 
 

 

[don4l]

I think that I'll give SRB a go.  I ordered my last adapters from TS, but the shipping was €16.

I've had another look at the camera and nosepiece, and I think that I need at least 8mm - so I'll go for a 10mm and have a bit spare.
