Here is another NGC6559 I took recently.

AstroPhysics Riccardi Honders 305 F3.8 and QHY600m.

A tough one to process. For some reason the posted image is less vibrant than the one on my screen in Photoshop. I don't normally see a difference.

Superb image Greg.

Nice and vibrant and lovely 3 dimensional detail.

Very well done :thumbsup:

Thanks Peter. It was a lot of trial and error to get it to that point. Some images fall in your lap and others you have to work for.

Fantastic image Greg, one of my favourite areas. :thumbsup:

The posted image looks very vibrant to me Greg. Nice work.

[gregbradley]

Thanks very much for the compliment.



Looking at it again yes it does.

Nice image scale and resolution on that one Greg. You've got some nice details in the fine features. :thumbsup::thumbsup::thumbsup:

[gregbradley]

Thanks Marc. Its bit of a hard one. Marcus Davies rendition is probably the gold standard.

Just had a look. He has more integration time but you're holding your liquor.

[gregbradley]

Hehe, thanks Marc.

Hi Greg, You know I really respect your imaging, but - I've been biting my tongue on this one for a while, but I figured you might appreciate some honest feedback for what it's worth. :scared3:

It's very magenta/purple and there's no clear definition between the blue reflection neb and the Ha emissions. :question:

Stars are blown out and have next to no colour.

The details and shock fronts do not appear to be very sharp.

So I could do the usual thing and say something nice, then say what I really want to say etc, (but it's been 8 weeks of lockdown here too now, so maybe my usual warm fuzzy diplomacy is wearing a tad thin) - so I'll apologise in advance if these comments are in any way offensive, and as mentioned above - suggest that you compare yours to Marcus' (https://pbase.com/gailmarc/image/116319109) and take it from there. :D

I have to disagree with this assessment. There is a difference in the integration time and SNR. Bright stars are larger than Marcus's version but the smaller ones are much finer and more defined in the background. Likely due to transparency at the time of capture. The shock fronts are exactly the same in both images with an excellent level of details.. They are sharp and detailed where they should be and diffuse in other parts. Greg's rendition is a little noisier but it is to be expected and he presented a truthful view of the object.

All good Andy.



Cheers Marc.

This is the AP130 image which I personally prefer:
