Adapter wanted, or a "man that can"

[daz]

Does anyone know of an adapter that is female threaded at one end to fit the Skywatcher ED80 focus tube, and T threaded at the other?

Or does anyone know anyone that can make such a thing??

Am trying to elimate adapters with thumbscrews / set screws to firmly hold the CCD camera and Filter weheel square to the drawtube...

Hello,

Scopes'n'Skies do a 1.25inch nosepiece adaptor which has a T-thread one end and the nosepiece end is threaded for 1.25inch filters for less than £10.00GBP including P&P. Sorry but I cannot remember the part number. I ordered one a few months ago.

Hi Daz,

I can imagine such an adaptor would have to be custom made, but it might be cheaper and even better to use a Hotech SCA - it centres itself, so doesn't even rely on the ED80's thumbscrews.

Adaptors - Hotech 2" SCA T-Adapter

Have you checked out the wide range of Baader adaptors???

Telescope-Service: Baader Adaptors

Thanks all - I shall go and investigate and report my findings

Hello Daz,

Sorry but i did not realise the SkyWatcher had a two inch focusser - however I found this item on the Scope 'n' Skies website AC018 2 inch and SCT T-thread camera adaptor I hope this helps.

Well, thanks all, but although these suggestions do essentially fit the bill, they don't provide the overall length that I need.

The imaging train needs a 50mm extension tube at present, and this is where the adapters and thumbscrews comes into play.

The other option is an after-market replacement focuser housing that is longer than the original.

Ah well, will keep looking.....

If you can get the skywatcher thread to T thread adaptor, you can then use the T thread extension tubes (Baader/ FLO) to give you the correct spacing. Secure and doesn't "flop"

[daz]

Ah, that's a good idea Merlin!

So I could use the Hotech SCA T adapter and then extensions onto that..... Like that thought!

Oh dear Daz, it seems that you have been revisited by imaging fever. Having produced great images, the search for perfection has started.
