Exactly as the title says, can someone photograph his filter or find/make a diagram on how a COL filter should look like please?

They look like slightly under-sized darkfield filter. Examples here (see Figures 4, 7, 10, 16 and 24):

You can DIY, though I bought mine from this eBay seller (mine look exactly like the listing):

You can even combine several filters together to fine tune it.

Thank you zzffnn, that information is most helpful.

I suggest reading all of those articles.

Regarding making a phase telescope, I concluded that unless one owns oculars to use in making one, there is no savings over just buying a phase telescope,

Sorry, I gave the wrong link.

Here it is: http://www.microscopy-uk.org.uk/index.html

Click on "library", " Techniques - lighting" then "oblique and COL". You will find quite a few articles to read on the topic.

Thank you zzffnn for the link.
charlie I do not intend to make a phase telescope yet, but thank you for the tip.
