VDB136 and a Diamond Ring Cluster

[Mark72]

Hi guys,

Diamond Ring is actually invisible but it's not my fault this time. It can only be seen in IR spectrum.

There is still a lot going on in this image. VDB 136 is in the centre. Around it is a dark nebula and this blueish tint is not accounted for post-processing artefact but rather dust scattered across.

There is just one reference image I could found in Internet - magnificent work of Tom Davis. But unfortunately I have neither ASA nor TeleVue, Just modest effort with my noisy Canon

It's nice.

Is the round thing to the right of VDB136 just the faintest hint of the engagement ring, or is that something else?

I often find that equalising an image helps me spot all the faint background things that are in the data, so I did that with your second image. The large pink circle just below mid right looks like it's the ring... is it?

Though I haven't found a way to use the equalised version as a layer (yet) it gives a target to aim at - the trick being to lift the faint stuff without blowing out the bright stuff and also bloating up the stars _ a trick I have yet to get the hang of.

Well, interesting idea. The ring was mentioned in Tom's description. After I researched it a bit more I found it in the following article http://herschel.cf.ac.uk/results/cygnus-x

Need to plate-solve my image then to check again. Thanks for your comments

You're welcome, it's a good image. I was just hoping that you'd managed to capture a really elusive target.

[Mark72]

May be you are right. This could compensate for bloated stars

Seriously I think as mod Canon gets its IR filter removed maybe there is something in IR there. If LPS filter did not cut it.
