Looking for the 2" low profile extension tube that is provided with most of the skywatcher scopes. I have a used 190MN that didn't come with the extension tube and need it to get accurate focus. I believe Orion scopes may have one too.
Hi there, I'm looking for an extension tube to put on top of my Tripod. It's an AVX Tripod, but I won't be using it with an AVX head; it'll be used with a Giro Ercole mount. Both the Tripod and the Ercole Mount have 3/8" threads on the connector. I know it's difficult to get an extension to which the AVX mount itself will fit, because it requires a North peg in a different location from the usual Skywatcher types, but that's not an issue here as I'm attaching a Giro mount, which as far as I can tell does not require a North peg, but tell me if I'm wrong. All I really need is an extension which will physically fit on the AVX Tripod, not the AVX mount. Any ideas?
Hi there, I have an Explore Scientific ED127. The focusser takes 2" eyepieces. It has two screw-in barrel extensions, each of which extend by 37mm. I've determined that for my range of eyepieces, it would be perfect to have one barrel extension of about 50mm. The only trouble is that when searching, there seem to be a plethora of different widths/fitments. Which one do I need? I know it's not the T or T2 type fitment. Is the kind I want called M48? It has to be threaded so it will screw in to the focusser (about 5mm of thread). It also needs to have a female thread at the eyepiece end to accept filters. Finally, it would be great if it had a compression ring clamp on it - though that is not necessary as I already have a seperate one (if I can manage to unscrew it from my existing extension! Any advice appreciated!
