I was thinking about the skywatcher 2x deluxe Achromatic barlow as that has a camera screw adaptor fitting as well as thumbscrew, so Ideal for my Nikon thread mount. Would this be any good (seems rather cheap!)

That's good to know. Now I know that a 2x barlow works I'll look at better ones. Mine is "Celestron 2x Barlow lens". No idea if that's 'good' or not.

Good news, I managed to get both cameras to reach focus on venus last night with the 2x barlow. Actually achieving sharp focus is way more tricky than I imagined, especially with the planet shaking all over the place (live view), but that is a different skill I have to learn. Also, the image had massive chromatic aberration but that could be collimation, the scope mirror quality or the barlow itself. Thanks very much for the help

Thanks, I'll see how I get on with the barlow with both cameras tonight Good suggestion for the local Astro club. I think I have one fairly close. I'll get in touch with them

I'll try with the barlow tonight. Unfortunately the barlow doesn't have a thread so I have to use the full T adaptor. I've attached photos of the camera without barlow and just T adaptor thread section screwed straight on the focusser and with barlow with full T adaptor push cylinder into the focusser. My focusser seems to possibly be longer than the one shown above., but not sure it's by much Can the focusser on the skywatcher newtonian be replaced? I'll also try my micro 4/3 camera. The adaptor for that doesn't disassemble to just a thread section, but the focal plane to front of camera distance is a bit shorter. Any help appreciated. .

Hi, Alacant, thats basically what I did last night, my adaptor ring comes off the T adaptor and screws straight on to the focuser tube. I'm clearly doing something very wrong. I tried to image a planet last night and could only see the primary mirror.....I need some serious help...

I may try tonight but as the moon doesn't rise until silly o'clock, not sure if I'll have anything to focus on !

You mean without the barlow in between? Yes it will, never though of connecting that way. We have a couple of days of cloud here so it will be Wednesday probably before I can try it

Photos attached - Adaptor on camera, barlow, barlow on scope, camera on scope with barlow between camera and scope. Lovely shot - I can't seem to get mine to focus at all. I have a skywatcher 130

Hi Peter Thanks for the reply. I tried a 2x barlow but that didn't appear to fix the problem. Do I need something higher? Cheers Steve

Hi I know this is a really basic question but couldn't immediately find the answer. I have a skywatcher 130 newtonian and want to try and photograph with either my Nikon DSLR (D500) or Olympus micro4/3. I have T adaptors for both. I hit the immediate problem of not being able to get either to focus and a quick search has shown this is not an unusual problem. I have no idea how to resolve this and am looking for advise please. I have read about 'flatteners' and such like but no idea what they are! Any help greatly appreciated.
