A descent x3 barlow

[JamesF]

I will have to defer to others on that one as I've never bought one.

Do you know anyone with a lathe? Turning a lump of aluminium and painting it black would work

yes it was that one.....cheers james!!....had a panick on for a second then.......next question......50mm extension tube.....where from?? i dont wanna take the lense out of my x2 barlow!

bungielad.

also from this bit

the x2 im using at mo is the delux skywatcher..........

the lens unscrews from the bottom of that barlow giving you a tube? dont know if it would be the size you need but after unscrewing bottom lens no other glass is in the tube

it breaks down into 3 pieces,i have one for my setup

[Bungielad]

Yep...it unscrews, didn't know it did that, another thing iv learned, really thankful for all this advice, thsnks loads folks.

just a point on using an old barlow as an extension tube - should be able to source a cheap second hand skywatcher or celestron x2 barlow for £10 on flea bay, and as you will be disguarding the lens not need to be too fussed over condition. Although for imaging, especially with additional extension tube, keeping everything rigid and concentric is important and a purpose built extension tube with copper compression fittings will be more solid than cheap screw clamp type.

This one from TS Optics via Amazon looks pretty handy @ £ 20 - http://www.amazon.co...s/dp/B004OVTWMS

Edit - Missed the £8 postage - might be worth speaking to Bernard at Modern Astronomy as he stocks most of the TS Optics bits and is usually more competitive than going direct for small orders.

Iv just seen a revelation 80mm extension tube for £23 including shipping costs....would that be to long??

[JamesF]

I think 80mm might be too much in one go. I'd try something shorter first.

+1 for Merlin66 comment - I have a Klee x2.8 and it is a real joy to use.

If you go down the route of using extension tubes, I used this chart to set myself up, to meet my wishes

[Bungielad]

Nice little graph that is..cheers for that.
