Thanks Dave. The pic is just a 5-image stack taken in bright field using a 2.5/0.08 objective - the only one I have that will fit the entire arrangement in a single frame. Pretty low res and therefore somewhat soft IMO.
But you're right, it does show the diffraction colours nicely. Compare the hires image below, taken with a 10/0.35 Planapo (15 mosaiced stacks). Obviously it lost fine detail being downsized from 6k to 1k square for posting here but it's a lot sharper and will make a nice A2 print. Not sure if it necessarily looks better than the other one when displayed here though.
I've added a closeup of the centre of the rightmost spiral as a final shot of this arrangement.

I'm looking for the the extemely rare V-IM magnification changer for the E800 scope. If you have seen a listing or have one for sale please let me know.

This is glorious work!

An idle thought: what happens if you pull both images into Photoshop, upsize the lowres one and align it with the hires, then convert to Lab color and make a new image from the hires L channel and lowres ab (color)? I'm wondering if this would preserve the nice colors that we see in the first image, while also keeping the fine detail that we see in the second.Beatsy wrote:[lowres] does show the diffraction colours nicely.

Yup - it works fine - here's one I prepared earlier.rjlittlefield wrote: An idle thought: what happens if you pull both images into Photoshop, upsize the lowres one and align it with the hires, then convert to Lab color and make a new image from the hires L channel and lowres ab (color)?

Great minds and fools etc...
