Re: Microscope Cameras?

Hi Hobbyst46 Canon does't sell a mains adapter for the 4000d. I have searched the net and the Canon website and such a thing doesn't exist. Some people have bought the "subtel® Netzteil kompatibel forCanon EOS 1100D 1200D 1300D EOS 1D X Mark II EOS 2000D EOS Kiss X50 X70 X80 EOS Rebel T3 T5 T6 T7 CA...

Re: Microscope Cameras?

Hi Dave I have spent hours searching the web and all Canon cameras that I have found need to be powered from either the battery or a DC coupler. None of them power through the USB port as the voltage is around 7.4v and a USB only delivers 5v. In the case of the Canon, using live view requires 7.5v @...

Re: Mold, bacteria biofilm, parasite, or something else?

I lived in Cambodia for over three years which has a very hot and humid climate. There were lots of black mold on the buildings and during the summer there were thunderstorms and rain every day. Just before the rain came I would start to sneeze and have a runny nose with some shortness of breath cau...

Re: Mold, bacteria biofilm, parasite, or something else?

Looks to me like some kind of mold or fungus spore. There are billions of these floating around in the atmosphere including the ones we like to eat. Most people are not affected but some are sensitive to certain spores myself included.

Re: Microscope Cameras?

HI Dave If you want to power your camera from the mains there are some options. Big problem is the battery door must be closed to power the camera on. Unfortunately the is no exit for the cable and as there is a micro-switch which needs to be pressed by closing the battery door it needs a fix either...

Re: My First Images with Canon DSC4000

@mrsonchus.

Thanks for the encouragement (much needed).
I have tried a self made darkfield patch from Olivers video, which seems to work quite well even on this very opportunistic slide (squashed under a coverplate with water).

Re: Condensers...

Perhaps if you take the measurements of your condenser other members can look to see if their condenser's are the same or different. You can look at the manufacturers of those that are the same.

Yes much better and they speak English too.

Good information here. I got my T2 adapter today and guess what? I can't get focus on the camera. Even taking off the top mounting collar it's still just outside focus. I will talk to them tomorrow and see what they say. Plan Infinity Objectives. I also have a 10x eypiece extra.

This may seem a bit oversimplified but, have you checked the grub screw for tightness? Or maybe the grub screw is broken and allowing the fine focus wheel to turn on the shaft.
