Crayford focuser extension tube?

[crepitis]

Hi, I am having problems bringing two of my 2" eyepieces (9mm Nagler type 1 and Meade series 4000 UWA 14mm) into focus on the Crayford focuser on my Revelation 10" Dob. I understand that I may need some kind of extension tube.

Anyone know of a UK based supplier of these?

I know they exist because I found a couple of US sites selling them, but they dont ship outside the USA.

Thanks for any help.

Cheers, bob.

Hi bob, I have the same problem... I just swapped my 2" 2x Barlow for an elctric focus unit for the crayford. An excellent swap as the elecy focus is GREAT!

But I forgot that I used the barlow (with the lens removed) as an extension tube...

I've asked Bern at Modernastronomy to get me one - he's finding out a price and as soon as he does I'll let you know Bob.

I've got some stuff going on at the moment and may not be around for a while - give Bern a call direct if you wish www.modernastronomy.com - these adapters are not on the website soyou'll have to call him. His telephone number is on the website

If you haven't heard back from ant, TS in Germany do them for 25 Euros

The problem with TS is that they charge a fair wack for shipping and you have to pay them in Euros via paypal who take a few percent making the total perhaps around £30? 

I should have some this week for less than that.

If anybody is interested just send me a pm or email.

Thanks for the help Ant and Daz, its much appreciated, I managed to get them into focus by using them in the 1.25" adapter, but I think I will drop Bern a PM, thanks also to Jamie.

Cheers, bob.
