NGC6188 from Duckdang

[EddieT]

Hi all,

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.

Lots of nice detail there Eddie for us to drool over! great shot. Its is really the fog lit up with a red torch isn't it. LOL

[EddieT]

Ha, yeah Houghy, I wouldn't doubt that there is some Duckadang fog in this image :).

I really should check the JPG conversion before I upload images. The uploaded version seems to have been desaturated. I'll repost it later.

[h0ughy]

I don't see what's wrong with this version its great! :poke:

[atalas]

Wow :jawdrop: Its so three dimensional Eddie,fantastic shot !

Louie :thumbsup:

[EddieT]

Yes it's fine, just lost a bit of colour compared to the version I've been staring at for the last 5 hours :)

[EddieT]

Thanks Louie !

[h0ughy]

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 :doh: :rofl:

Wow I've never seen so many stars in one photo, very nice Eddie.

Incredible shot Eddie, really nice work. Can't wait to see the full version mosaic.

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.

[EddieT]

Thanks Ed, Mike and Paul.


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. :doh:

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. :violin:

And that constant urge to reprocess images because you've find a better way of shifting bits. :help3:

If I wouldn't be into astrophotography I would have raised 4 kids by now. :family2: (Always wanted to use that one!)

Just post the link of the big version when you have found your saturation :rofl: , I won't take 5 hours to look at it, but it will still be for quite some time. :D

Cheers,

Hi Erwin,

Wow, that is one emoticon-intensive post! I'm still working to get past the smiley face :)

Here is the web page with larger versions

Incredible shot Eddie, the fullsize version is fantastic. So much to see in there.

[EddieT]

Thanks Mike,
Glad you found and liked the full-sized version. Many tend to miss the little links beneath the image.

[EddieT]

Erwin,
a more detailed response to your post...



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.

[davidpretorius]

wow, now there is a level of bar setting to have a crack at. lots to learn, but wow, what fantastic results!

[davidpretorius]

why can't i find ngc6188 in starry night pro?

[[1ponders]]

Its there david but you may have to increase the number of NGC items displayed in the deep sky options box.

[ErwinvdVelden]

Thanks Eddy,

Terry Lovejoy is battling with the same background light level problems from his place in Thornlands, but since he can't go to a dark site easily because of other commitments it is a thing he has to deal with like you do.

I'm just lazy and go to Leyburn, a dark sky with a DSLR of more importance than with a CCD because of the quantum inefficiency when using narrow band filters, like the Sulphur filter :D . Although the Baader UHC-S filter is a big improvement.

Cheers,

Erwin

Eddy,

There isn't much I can add to what's already been said in this thread except to say this.....
Your images are always an insperation, I always enjoy your images.
And congrats on winning the David Malin award :clap:

[EddieT]

Hi Andrew,
Thanks for that. I'm glad to have a forum where I can share my works with an appreciative audience.

[h0ughy]

The going rate for favourable reviews is $5 per comment :D :whistle:

[EddieT]

Wow, I'm going to stop imaging and start reviewing :)

[h0ughy]

Just keep up the good work Eddie!

[EddieT]

Thanks Houghy, I think I'll be imaging until I'm no longer physically capable!

[xrekcor]

Man I must of missed this one :ashamed:

Now that your posting here in Deep Space regularly, I'll have to take a looky more often.

Excellent shot Eddie I love Astro images you can sit and poke around in.

regards

PS: Guy's if you really want something special take a look at Eddies Milky Way in H-alpha, even better buy an original print preferably the large one :D

btw, I'm no way affiliated with Astroshed, just a happy customer :)

[EddieT]

Thanks Rob. Glad to hear that you like your print! The large one is certainly a gob-smacker. I want to put one up here somewhere but don't have a wall big enough !
