Re: Q-Tips OK for microscope optics cleaning?
I've switched to foam tipped swabs for both microscope and camera optics. Not so much from concern over abrasive inclusions, just sick of cotton strands getting left behind on surface.

Re: How many of you mix Objective brands and sizes?
I use mixed brand objectives on my Vickers M17 but like all of them to be parfocal. The Complan eyepieces that came with the scope work well with Zeiss and Zeiss-Jena objectives of that era. One objective (Zeiss Jena 6.3x apo) needed shimming. The 2 objective changers I have for the microscope use a...

Re: When was the golden age of Microscope hardware, and what Scopes from that age have survived the test of time
Early 1970's IMO. Usability and ergonomics got more attention, engineering and quality control was good, plastics not generally used in critical areas (some exceptions).
Styling can be questionable though.

Re: Best way to darken a microscope barrel?
I was in a similar position with a diy tinocular tube. I had some clear matt lacquer and added some black printer toner from a used laser printer cartridge. It made a good blackout paint, still well adhered 3 years on.

Thanks, Nice easy going review with enough detail. If I where looking to reinvent my budgeting strategy it is spot on.

The front plastic diffuser on LED spotlight bulbs works well. Most are domed to some degree, but there are flat ones if you shop around.

Re: Are there low-power oil immersion objectives?
The oil immersion objectives below are Vickers 50x 0.95 NA, one is Fluoro, the other PlanAPO. Both are excellent objectives. They crop up on eBay occasionally and tend have a lower asking price that Zeiss/Nikon etc. I can assure you its not because they are inferior, sellers are often not familiar w...

Re: Cotton rolls for lens cleaning?
Same method for me as my camera lenses. Foam buds with isopropanol, repeated with distilled water, dried with a makeshift blower (a large hand-pumped plant sprayer). Trick is not to over-wet, anything with fibres is a no for me.
