Another couple of oblique stacks from the Puente Formation fossil sample.

AO Series 4 Apostar, 90x Apo, oblique mask, Canon 70D, Stacks as indicated, cleaned up the background

OMG, Rod - LOVE those pics! I must admit, I have a guilty pleasure of looking at home astronomy setups on the internet and I have visited your site before! I am intrigued by those ortho illuminator pics and particularly like that paint finish on the ortho. I have been doing a lot of paint finish an...

Bob, Since you don't have access to many American Optical scopes, here are links to a few pages of pics of some of my AO scopes. Some offer close details that catalog pics might not provide. http://www.homebuiltastronomy.com/AmericanOptical20Phase/ http://www.homebuiltastronomy.com/AO4/index.htm htt...

Thanks, I have a lot of fun with them. My 10 on the Ortho is a dedicated darkfield stand. It has the 1096b Toric condenser, which is nice as it will fully illuminate everything from a 10x to 100x objectives. It also has the 100x Iris objective to allow for some tweaking as needed. Really a nice luxu...

Welcome the AO Anonymous. My name is Rod and I am an AO-cholohic.... I came at it from a different angle. When I got interested in Microscopy a couple of years ago, I was looking for an affordable stand to see if it was as much fun as I imagined it to be. My first was a One Fifty, an entry level mod...

A couple more from the Puente Formation in California

AO Series 4 Apostar, 90x Apo, Oblique, Canon 70D, Stacks as noted.

Thank you Jim

Phase really struts its stuff on this subject, look at that structure!

Cool stuff, thanks for posting.

I keep looking at the centric in image three. The "spots" keep alternating between raised and sunken as I view them. If I look and see them as raised, I can look away and back again and they become sunken. Anybody else, or should I see a doctor? ;^) Reversals like that are a classic optical illusio...

Looking good. Mini oblique + mini µm steps is the way to go. I keep looking at the centric in image three. The "spots" keep alternating between raised and sunken as I view them.

Merci Beaucoup Seb

Thanks zz

Yes the first form, Actinoptychus, has a good bit of relief built in, hard to miss with that one.

lol edit; "last three images" would have been a better way to put it

Thanks Aenima, I knew what you meant ;^)

Thanks Pete.

I am not sure I have seen that diatom before, and the oddly shaped bit to the right of it adds some interest too.

Glad you liked it.

After encouragement from 75, I set out this afternoon to see what I could come up by way of stacking oblique images. I was concerned about artifacts from the halos that you get when changing focus point in oblique. I reduced the degree to which pushed the oblique effect and it think it helped some. ...

That structure blows me away! Who knew that it looked like that?

Great detail and stack.

I agree with 75, a dark background would be an interesting image as well.

Nicely done Kit.

Looks like hundreds of hours of fun to me. Congratulations.

Ebay, Garage Sale, Goodwill? What's the story?

Wow! This is a great image! What a cool subject, and you completely captured the fascinating and intricate form. The 3D effect is especially pronounced on the second one. Your stack looks to be perfect to my eyes. If this is what we can expect from the new scope, it is going to be a lot of fun aroun...

75- I dont think I have ever tried stacking with Oblique, I wonder if it would work well? It seems to me the halos might pose a problem. Any experience? I found that stacking works well with a gentle oblique. Go with subtle and let the cumulative effect of the series of images do their thing. You m...

Hard to beat polarized crystals for color and fascinating structure. Really like the sense of depth from the oblique lighting.

Great series Seb.

Thank you gents.

Kurt, it surprises me too, it seems counterintuitive.

A few more from the same sample.

Really vibrant and striking images. Top Drawer as usual 75

Great photos.... I know exactly where these were collected.. Kurt is right, It is a dangerous 90 deg. turn in the road... used to fish in that area back in the day... BillT Thanks Bill. Kurt had said in his original post that he was driving by and noticed the diatom material laying out there - hard...

I am still looking to find one of those super cool Sigma forms... Ah yes, Gyrosigma fasciola, a very pretty thing. Give me a shout if you don't scare any up, maybe have to send you another bit of sample. Scanned the rest of the slides tonight - no luck, but I have more sample left, so I will throw ...

Nice images, Rod! Kurt's collection spot is not far from the collection spot of your Armand Bayou sample, belonging to the same connected water body and more towards the ocean. Thanks ZZ. This sample is quite different from the bayou sample, not as diverse, smaller in size, and leans more towards f...

Nicely done!

They look perfect for the job, and at a bargain basement price.

Great idea.
