Bresser Mikrocam SP 5.1 camra

Microscopy of fungus from plant pot in kitchen 9/12/2018 – Leitz Laborlux 11, Bresser Mikrocam SP5.1 camera, oil immersion objective

This fungus was growing on the earth around the base of the plant in a plant pot in our kitchen in Lichfield. Interconnecting hypae can be seen but the stand-out difference between these photos and those of fungus on bread and cheese I have posted in past is the lack of spores.

  • Leitz Laborlux 11 microscope.
  • Magnification 10-100x objectives. The 100x objective was oil immersion and I could not find the proper oil so used extra virgin olive oil as my immersion oil!

Algae growing on Pot Plant Slide 1/12/2018 – Zeiss IM microscope; QHY6 mono camera vs. Bresser Mikrocam SP5.1 colour camera

About a month ago, I placed a slide in my pot pond outside and the algae on the photos below are those that have grown in situ. The slide was in the top ten centimetres of the pot pond – where sunlight would hit the slide every day.

This has also been an opportunity to try out my QHY6 mono astronomical camera on my Zeiss IM microscope & compare photos taken with that camera with those taken with my trusty Bresser Mikrocam SP 5.1 camera – the main issue is the small sensor on the QHY6 gives highly magnified image & loss of detail as in monochrome.

Successfully attaching two different Bresser microscope cameras to Zeiss IM microscope and having both in focus with eyepieces on trinocular head

It has taken a while to get here but at last I have been successful!

Using second hand Diagnostic Instruments Adapters, I have now attached two separate cameras simultaneously to my Zeiss IM microscope. The advantage of this setup is that the Bresser MikrOkular camera (1.3 megapixel – HD definition) is brilliant for video, giving a smooth result at a decent resolution. The chip is quite small so I am using the 0.7x Diagnostic Instruments adapter to reduce this magnification factor that results from this – the end result is still more magnified that the 5 megapixel Bresser Mikrocam 5.1 camera produces in the Diagnostic Instruments 1.0x adapter.

The 5 megapixel Bresser Mikrocam 5.1 camera produces in the Diagnostic Instruments 1.0x adapter is attached to the second port on the Zeiss 910137 dual head block I have attached between trinocular head and IM base (horizontally in the photos below). The Bresser MikrOkular camera on 0.7x Diagnostic Instruments adapter is attached to the camera port on the trinocular head (vertically in the photos below).

The Diagnostic Instruments adapters have inbuilt focusing rings that allow both cameras to be bought into focus with the eyepieces. As the MikrOkular camera does not have a C-mount attachment, I have had to use a combination of adapters to attach this to the Diagnostic Instruments adapter. The MikrOkular camera fits into a 1.25 inch to 2 inch telescope eyepiece adapter, which itself slots into a 2 inch to T-mount adapter. I then use a male T-mount to female C-mount adapter to allow this to be attached to the Diagnostic Instruments adapter.

I have uploaded below pictures of the setup plus photos of Seed of Castor sec (commercial slide) observed using a 32x objective. Those photos are taken without changing focus setting so demonstrate the difference in magnification scale between the two cameras.
