Yes, I would agree, you get a great deal for your money with second-hand, in terms of quality, adaptability, and expertise around in using it. I too am based in the UK, and there are meetings where there are sales, often run by one or both of the amateur (mostly) societies that exist, the Quekett an...

The plant hairs or scales can make interesting polar objects too.

Only had this one dirty picture to hand, but you get the idea.

Have these been 3-D printed then?

If so, at what sort of cost?

I presume the polarising filter is to cut down reflections. This in itself of course cuts down the light, making it more difficult to get a fast enough shutter speed. I might have missed it, but you don't mention the camera. However, the use of your manual lenses suggest you are not using IS. This i...

Thanks for the clarification, looks like things may have changed, though of course there are many many images classified (honourable etc.). On your last point, I will be interested to hear from others, but as I understand it, ( and this is one of the interesting things about competitions like this) ...

I used to enter the Nikon Small World and the Olympus Bioscapes comps, back when Michael Davidson was involved. However, I was rather put off the former by the fact that merely entering seems to give them right to use your photographs where and when they want, irrespective of whether they are 'place...

Re: WTB (UK) Century precision optics 4+ diopter

Anyone? I don't have one of these, but I do have an Olympus MCON-35, a high-quality close-up attachment lens originally for the Olympus E-10 camera. It is fitted with a 62-mm front thread and is multi-element achromatic. The focal length of the MCON-35 is 35 cm (according to Olympus), which transla...

Re: Nikon SMZ-2T and camera connection

I have one of these with the photo tube which I understand is not the generally popular 38mm size. Ebay seller Amoyca2011 does s couple of plain tubes, one short one long, and one 0.5x - I'm not sure which I'd need . https://bit.ly/2CXQHev I'd like to use a camera such as ebay 113323869694 or 30299...

I rather think that shipping to the UK may be too expensive, but will ask anyway.

I didn't realise you could tell what I am a regular user of ! To explain... I just followed the link in your signature to Flickr and looked around.

I am intrigued and puzzled by the question/suggestion being discussed here. Reviewing portfolios, I also see -- or at least I think I do -- that both Harald and Photomicro are regular users of fairly deep stacks. Do you guys ever publish individual frames to accompany the stacked result? Why or why...

Re: suggestion for photography through the microscope

There must be very many forum members and guest who look upon the results shown by members, and stop and think i like to try that?. Not every one has the facilities to start stacking, consequently they get very disappointed when viewing through the microscope similar subjects. Would it be to much o...
