Celestron Universal T Adaptor alternative make

[astrotyke]

Hi there, im currently looking for the above, but I seem to think that 20-25 quid seems a bit steep for what it is. So does anyone know or could recommend an alternative brand that I could use. I have the tring to go onto the Canon dslr already. Its to go into my 6" celestron SCT so its the 1.25 size im looking for.

Thanks
Chris

1.25" with a DSLR will give you some vignetting....keep that in mind, would you not be better with a 2" version ?

Er pass lol, you tell me   would I? My scope only has a 1.25 visual back so id have to change my eye pieces wouldnt I if i changed it to 2inch? im new to using a dslr in a cope so just learning.

You would probably need a new 2" visual back for the scope, then you have a 2" to 1.25" adapter so you can still use your 1.25" eyepieces.

you then have a 2" nosepiece on the DSLR that slips into the new 2" visual back....simples

You could also look for the parts secondhand on ABS or astroboot....probably save quite a bit

ooo, thanks for that Skybound. Plenty to think about then I guess on that. Yes i wouldnt be bothered about buying second hand on them, im sure secondhand will be fine  I shall have to have a think of what to do then shop around

A quick question, how does fitting a 2inch visual back help with the camera, as the exit hole at the back of the scope is only 1.25 inch across?
