Connecting DSLR to Swift stereo?

Hi guys
Just bought this stereo microscope which comes with a 0.5x c-mount (male thread) fitting on the trinoc tube and wondering what extra adaptors I would need to connect my Nikon d5500 dslr to it?. Any ideas please?.
Thanks
Steve

Re: Hdmi imaging anyone?

Yes I’ve seen that camera advertised a few times John and did think they were a little shall we say optimistic about the claim of 48meg on the sensor!. You happy with this camera?

Hdmi imaging anyone?

Hi guys Looking around for a new camera for imaging I did wonder if any one has experience of imaging using hdmi type cameras and if they can give high def screen shots comparable to usb connected ones?. Reading up on a few in particular the Hayear 4K range they have some nice specs. I don’t envisag...

Betaine in some Red Bull drink!

Bit of a mixture of the two but seems to work ok. Slide heated over a t-lite candle.

Rotating stage for Laborlux S

Hi guys Been imaging crystals lately and they are not always in the right postion on the slide so came up with this for my Laborlux S scope. Attaches to the x axis slider. Trying it both with the conveyor bearings and without, prefer without I think. Its turned gently by thumb and the slide pushed o...

Re: microspectrophotometry

You might be wondering what the little guide ccd at the side is doing?.
It’s to show where to place the 23micron slit on the slide for entry to the spectroscope. The same use with a telescope placing a star on the slit!.

Re: First try adapting astro gear for microscopy!

Yes thanks although I'm not too sure cooling the ccd would help with microscopy as these exposures were Red 0.01secs, Green 0.01 secs , Blue 0.008 secs and I cant see noise being a problem with these exposure times. Onwards and upwards as they say 😊

Hi guys I stopped doing astronomy a while ago and still have all my gear and thought about combining it with my microscopy. I have a little toupcam which I like using but it never quite gives the resolution I wanted, neither did my Nikon D5500 dslr so the thought of using my 16bit cooled Atik ccd ca...

Re: Cooled ccd for microscopy?

Also does your camera do high speed video? Bob No it doesn't Bob they are mainly for imaging very faint objects doing long exposures (up to an hour) the ability to cool is to make the ccd more sensitive and reduce electronic noise from the chip.I can maybe see the use with microscopy such as fluore...

Which app MycoCam,Altami or Toupview? I have heard Altami 3.5 had a few issues but I never tried it and after posting on here I was given a free licence to beta test v4 and so far so good!.

I read that if you use an oil immersion objective either with the wrong oil or no oil at all you get spherical aberration??

Thanks for info, I think maybe it might need a clean- just lens cloth and cleaner ok?. I've never used an oil objective before so will have to checkout the do's and dont's of that

Hi guys
My trusty Leitz Laborlux S came with 5 Leitz Wetzlar objectives giving x4,x10,x25,x40 and the last one x100 which is labelled Wetlzar 160/0.17, NPL Fluotar 100/1.32 OEL. Would I be correct in thinking it's for use with oil as it doesn't show a great deal of detail without?.
Thanks
