Must agree, not my area as they say, but really interesting images and the link is to a very readable (for such as myself with no Diatom knowledge at-all) and interesting article! As mentioned, the variety of forms must surely be a response to optimal requirements in one way or another - clearly a f...

Another superb one!
That's a great image - the 'strands' are clearly visible!

Wow! Chunky!

Very nice, and pretty stunning.

Forgot to say also, the moss branch is in water, not quite covered, hence the blown highlights - complete immersion or none at all would improve this detail.

An intriguing image, very nice.

Hi, agreed, those are nice images! I used a black card circle to get DF on my stereo 'scope, DF stereo disc (1).jpg https://lh3.googleusercontent.com/mlg9xp53ShFJ582gWU5Mru6xrgbSCQ0WcjZm7HCz0gucDeYd8WWdLO1YVvpIDd95mE4nep-k06GYpNmaL3cuqwCSJ8RbMHFZXJu18KehGMQMqSRHsXyfD4_qcXTqO3ys7pIpwvHRVvVR2iGVcpMtf9...

Yes, I thought the abscence of correction ALA infinity systems may be the reason. They're 'up on e-bay' right now if anyone's interested! I just acquired a BX50 (no objectives or condenser) with it's deliciously-bright 100W lamp and built-in filters, sooo, I will shortly have a nice trinocular BX40 ...

Thanks again scaro' - very useful to know. I was surprised to find that they not only gave equal quality views (with UIS2 objectives), but what certainly appeared to be, equal FOV as the Olympus eyepieces, as used in the Olympus BX40.....
Tomorrow I'll check this more accurately and get back.

Thanks Scaro' - that gives me something to go on - any idea what the series of numbers signify?

Off to look-up stemi 'scopes!

Hi all, I just acquired these Zeiss eyepieces and wondered if anyone may be able to give me some information about them. Incidentally - when put into a BX40 they perform absolutely the same in all aspects - quality, field-size inc, as the BX40's Olympus eyepieces. A few images, https://lh3.googleuse...

Hi Kurt,

a really striking image - very interesting indeed. Have you mounted it in water under coverslip?
It really does match 75's ID suggestion well I think.

Welcome Sara, you'll find plenty of friendly-folk here!

It's a good thought 75', as a full-frame DSLR is a lot of money! I may well save a substantial amount by going for the lower-mag PE. I think I'll have a look around for a 2x or even 1.6x - my other option was a Canon 6D mk2, but the body alone is about £1200 - surely I may find a PE 2x or even 1.6x ...

Ah, yes I see the ful-frame sensor would be optimal for a 2x photeyepiece and 22mm field number - the 2.5x exceeds the field, and the full-frame will 'reach out to' more of the 22mm field (using 2.5x PE) than the APSC sensor - thanks 75' that's exactly the info I am looking for. In my case if the gr...

Here's a handy link re camera attachment... . Reading through this it seems to me that the PE2.5 eyepiece (projection) will match a full-frame (AKA 35mm) camera's sensor? However, this seems to be with eyepiece FN of 18mm? The Olympus has a FN of 22mm (as does mine) or 26.5mm, so presumably the view...

Hi beemer, there are definitely other ways to connect a camera - there are some far more 'squat' adapters from Olympus that will do the job also although I don't know the part numbers I'm afraid. FF is a difficult one to achieve although I'm sure it's possible, maybe with a bespoke configuration? In...

Hi beemer and welcome to this fine forum! :D I recently moved over from Leitz (Orthoplan) to an Olympus BX40 myself and have been very impressed indeed with the performance. Connection of a DSLR to the 'scope is exactly the same as it was for my previous Leitz Orthoplan, here's an image of my BX40 f...

A beautiful image, again such detail - the resolution must be superb!

A good job done!
Time to get down to business!

Enjoy your new 'scope, and keep us posted on what you get up to!

Great news.
Yes, I've been a customer of Brunel since I first started in 2015. I bought a new infinity 'scope (SP200) from them then later progressed to a used Leitz Orthoplan - also from them. A reliable and honest source for certain.

What was the problem with the 'scope?

Hi, have you had a look while rotating the nosepiece a touch either way, in case it's the set-point (where each objective 'clicks-into-place' when rotated to select) of the nosepiece causing this?

Hi, this has the look of a nosepiece that isn't locating or isn't mounted properly, stopping with each objective misaligned from the 'scope's optical axis.

Excellent series Bob. Really good to see the progression of phases.

Nice work old chap, and superbly interesting!

A kind offer Bob. Yes, avoidance of the dreaded conjugate image planes! The Oly's are well-away from the FI, no problems there. Your idea of a set of holders is a good one I think, as the 3D-printer is probably easily capable of producing a holder with a thin lip, into which a glass filter of <45mm ...

Yes, they're quite a size! The BX40 has a neat little filter changer that fits onto the field-port and takes 3 in-out filters, unframed 45mm type. A very handy device but the 45mm filters are hard to find....

Hey, that drill-cutter looks to be just what I need to reduce some large filters down to a 45mm for my Oly!

Thanks for the post.

Hi, it stains starch, but is also a very useful mordant for staining with Gentian-violet, which will resist removal by alcohol when mordanted with an application of LI. See also gram-staining. I use it with G-violet with plant tissue staining.

Uh-Oh.... No Bob...nooooo.
We'll need to see release-images now to be sure you haven't released a bald hedgehog back into the wild!!

Keep up the good work old chap!

A fine-looking fellow he/she is too!

Tricky-one there Wes, seems at first-glance a good idea..... in principle certainly. It seems perhaps that the mechanism, in terms of how quickly the personae non gratae are removed, banned etc. Perhaps an automatic (i.e. without Oliver's attention required) removal or maybe suspension pending revie...
