Re: Any Bresser XPD-101 field microscope users?
Well, it's been a little while. Seems that getting into the cabinets I keep my microscopes in is a fall/ winter thing for me. I did travel with this to salt and fresh water locations and used it a bit in 2021, I would call it "played with it". Optically I found my Bresser XPD-101 decent, leaning to ...

Re: Zeiss water immersion objective front lens damage
Tissue culture growth media have salts of course but especially, proteins (think dilute blood plasma or fetal bovine serum). If dilute enough you may not get the opaque results as it dried/ aged as one may expect.
You may want to look at solvents useful for proteinaceous materials.

Re: phototube/ Nikon DSLR adapter for AO Series 10

phototube/ Nikon DSLR adapter for AO Series 10
Hi all; I have obtained a trinoc head for my AOSeries 10, and am looking for best options to mount my NIkon DSLR. I don't want to use a C-mount camera for multiple reasons. I have both DX and FX Nikon SLRs available, but would prefer to dedicate a DX body. What is the best way to be as parfocal as p...

filter holder for Model 735 illuminator
I don't know if they were an optional accessory or just got lost a lot (I did dig around on xmission but could not decide) but I have two model 735's that I would like to fit with brackets, if someone happens to have extra. I did see a forum post where someone modified a Cokin filter holder for this...

I really appreciate all the replies on this, there is a fair amount of discussion off and on since 2016 or so and it took me a bit to get the timeline sorted in my head.

Hi all; When I travel (we'll get to travel again, right??) I have my macro photography camera kit all sorted out, and recently I started looking at field microscopes.

Re: AO series 10 objective holder, washers
Thanks Pete, I was hoping someplace still had the small-sided objective cases. If anyone has a few spare, I could use a few! The spacers, I was wondering if they were for an adjustment but then every objective had them on, which like you say seems unexpected. If I can find my digital caliper (sigh) ...

AO series 10 objective holder, washers
Hi, As I build out the capabilities of my series 10, piecemeal. Sometimes objectives come with what I will call the small-format objective holder. It fits the objective closely and the holder fits the old AO accessories boxes. Sometimes in baggie or just naked. I see sources for RMS thread objective...

I am going to take a look at a few scratch-n-dent stereoscopes and I was thinking about taking some printed calibration / test page with me. I've spent a bit of time searching but don't find anything obviously made for this freely available. I am guessing something like a standard printer test page ...

Re: phase annulus for AO 10 phase objectives
That's great, I will keep that in mind for the non-dark objectives.
So for something like #1227, dark field oil, 34mm, that would work with the right-sized "regular" phase inserts, 0/1/2/ DF?
No need for a 100x-specific or #1227-specific solution (on the Series 10)

Hi, I've been reading a number of things and want to confirm: I would like to use phase with the AO series 10 I am finding parts and pieces for. Right now there are a number of dark (and some bright) phase objectives for this scope on ebay, but pretty much none come with a phase annulus to match. Th...

Thank you Hans and apochronaut. I really appreciate your looking and the estimate on when this was made.

A little while ago when a colleague learned I liked microscopy, I was given this scope. Looks like university surplus, so probably got bounced around a bit, last serviced in 1993 per stickers.
