Thanks Goose, have just tried that and seems to work at least on a quick 10 sec exposure from my light polluted skies, stars are looking reasonably sharp,
Going to try it on moon later but its not visible from my garden until 1am due to houses blocking it

Hey all,
I recently bought a basic T adapter and ring for my DSLR but it just doesn't seem to focus, after research I found that it will be very hard with just a normal T-Adapter as these newtonions aren't suited for it (Not long/big enough), better to use a webcam.
However I'd still like to give it a shot as naturally DSLR's will give better image quallity, I noticed this: http://www.firstlightoptics.com/celestron-eyepieces/celestron-2x-universal-125-barlow.html
Will this work/aid the DSLR and is it worth buying or shall I just wait until I get a bigger scope? I don't mind spending the £24 if it will work to get my first basic images.
I tried using a webcam which worked fine with a 25mm eyepiece (Moon imaging) but anything 10mm or below it doesn't focus enough, even with manual focusing (Microsoft Lifecam 5001). Which brings me to my next question.
Should I be using a webcam with an eyepiece or should I just use it like a T-Adapter with no eyepiece attached?
Thanks!
I just reread the OP and got confused.
A webcam will focus fine on a 130, a dslr will not,
but it seems he is trying to use a DSLR with an eyepiece,
Can you please clarify is that's the case?|
As normally with a dlsr you use a T ring adapter and a nose piece instead of an eye piece, it still wont focus on this scope, but at least will make sure we are talking about the same thing.
Also just youy the webcam no eyepeice

The 130PDS is a different beats to the 130P you should not have focus issues with the PDS version, as its designed to be used with a dslr, the primary is mounted slightly further up the tube than on the P version
-
Attach the Barlow. It then gives you an extra 10mm as it's just an empty tube then.
tried that on mine that moves the dslr outwards,, the problem on the 130 with my 1100d and any dslr is not enough inward travel

Yes It needs a barlow as the focus tube doesn't go in enough to achieve focus.
Problem is if you put you adapter in the barlo you get too much magnification sometimes so what i do is unscrew the barlows lens and screw it on the adaptor. This brings the camera about 10 mm closer to the tube reducing magnification
I have the same issue as the OP and am considering moving the primary but your idea is something I have not tried,
Just to clarify are you saying unscrew the lens form the barlow and attach that to the adapter or unscrew the lens from the barlow and attach the barlow?

Jason you can by a webcam nosepiece for around £15 they come in either a universal thread that fits most cams, or a designated one, for the Phillips cams, got mine from Rother Valley Optics, but other retailers may stock them
