here is one of my Duckadang projects. At full-size it's a big image, a 6-part mosaic of NGC6188 in Ara. I don't have the full-sized one online yet, this is a scaled-down pre-release version
Unfortunately equipment and weather stopped me from getting the whole thing, but I'm happy enough with what I did get.
Yes it's fine, just lost a bit of colour compared to the version I've been staring at for the last 5 hours
Did you try to open your eyes, I did and I still can't fit it all in!!! i think your nickname might have to be John West! if thats your reject then I'll have what JW rejects
One of the things that really impresses me about the image posters here (just one of the things ) is that you guys continually post shots that open my eyes to how many opportunities there are to shoot a fantastic shot. Objects that may have been seen in some form before, but never in quite the same colour, detail or perspective. Excellent Eddie.

Paul, the possibilities are endless really. I like mosaics at moderate focal lengths because they increase the resolution of the object compared to using a shorter lens. Unless you have a large aperture, short focal-length schmidt camera that is!
And this is one huge object. A mosaic at 900mm taking in the full nebula would be over 20 frames with the ST10, but it would possibly end up being the most detailed image of the entire nebula ever taken. That's the part that excites me the most. Amateurs can now take ground-breaking images. It's still a lot of effort, but it is possible to take images that are unique to the world and valid contributions to the global pool of astronomical images.

Phantastic shot Eddie, as far as I can see from the puny posted format!
Except for hitting your head against the counterweight bar while doing an exposure I find image processing always the worst pain in the bud.
The first bit (dark flat bias aligning stacking etc.) is not that bad (unless you find another method like I regularly do), but then I get stranded in a plethora of processing algorithms with 50.000 parameters. Not to mention the last fiddling with the curves.
And that constant urge to reprocess images because you've find a better way of shifting bits.
If I wouldn't be into astrophotography I would have raised 4 kids by now. (Always wanted to use that one!)
Just post the link of the big version when you have found your saturation , I won't take 5 hours to look at it, but it will still be for quite some time.

Cheers,
I agree, IP is a pain, but the better the data the less of a pain it is. It's no fun removing gradients, blooming spikes, excessive noise and trying to tease a bright background down to nothing without removing the bonafide low-level image info.
I found that the Duckadang images were much easier to process than any of the images I take from here. Dark sutraction, flat-field, alignment, sum combine, minor level adjustment and done! No need for excessive levels/curves and no need for any sharpening or noise reduction.
Its so three dimensional Eddie,fantastic shot !
