Astro-imaging guru Robert Gendler espoused using different optics to create composite images to give both scale and detail ...well... a while ago now.

It just took me a while to cotton on .... :)

My take on the technique here (http://www.atscope.com.au/BRO/gallery384.html)

Very, very good Peter...


I'm left wondering what you could achieve if your equipment was located at a better location... ?

Hmmm ... let's see, what superlative haven't I used for a while? :question: I know, .... WOW!

How about some specifics on how you blended? EG: How did you avoid big diffraction spikes from Alnitak?

Very nice Peter, the Flame region is spectacular!
My only criticism is the white line around the top of the Horsehead, looks like a sharpening artefact :/ The detail in the region as a whole is :eyepop:

Choke! :eyepop:
Can I see hairs on the horse's nose?

Looks like u used an X-ray machine in there as well :) Lovely image.

Thanks Clive...high praise indeed given your discerning eye.

As for a better location...:shrug:....I guess I'd spend less time in traffic in the high Chilean desert :) ...but then again..in H-alpha..even shooting from Pitt Street the sky isn't too shabby.



Thank you Marcus....to answer your question...only the horsie's core field was captured with the Alluna. The rest was RHA data...hence no spikes from Alnitak.

Nothing overly complex here...I simply used a Gaussian blur on the Alluna layer's edge to blend the two data sets. :thumbsup:

Man, o man, o man Peter! Bloody superb image, on another level!

It's stupendous in mono, but might you get some other wavelengths? I'm greedy, I know...

Peter,
A very punchy pony indeed!
Congrats,

A very high impact dramatic image :eyepop:

As Colin mentioned it looks a tad over-sharpened around the Horses' mane at that res though, probably compression artifacts, I'm guessing they disappear at high res?

Lovely rich detail in the flame and an interesting treatment of Altinak too :thumbsup:

Most impressive Peter!

The sharp edge atop the horsehead is likely a down-sampling effect, as the head itself has higher resolution (being RC16 data) than the remainder of the field (RHA data). I could lower the blend a bit there...then again...:question:
maybe not :)

Wonderful. The general steamy effects. The sharp detail in NGC 2023.

The horses stamping, their warm breath clouding, in the sharp and frosty morning of the day ...

Most impressive.

That is GREAT. The detail and 3D look is hypnotic!

Hadn't considered down sampling. So... Where is the Horse high res then? ;)

Perhaps I'll publish it if I ever get the RC16 colour channels ;)

Ah, Peter you need to stop doing this, we are sick of these images. :P :lol:
What can I say, Wow, :eyepop: beautiful image indeed.:thumbsup:

Leon :thumbsup:

A wonderful image.

I occasionally blend data from different scopes. Its adds an extra dimension as usually a widefield scope lacks the intense detail your long focal length scope gets. But the long focal length misses setting which the widefield captures so well. Best of both worlds.

Nicely done.

Greg.

Rather than take up too much band width I'll leave it to the emoji :thanx: !

A whole new level of awesomeness. Makes me almost forget the continuous rain in Sydney. :thumbsup::thumbsup::thumbsup:

Thanks Marc...I'm getting out of Dodge City for a few days...hopefully the weather will be better when I get back :thumbsup:

That is awesome Peter, very immersive effect. The Flame Nebula really stands out too :thumbsup:

Aw I dunno Peter... I can't see as many background galaxies as the Hubble version... you'd better try again :P :) :P :)

Thank you for your kind comments gentlemen....I'm hoping to add to the data set soon.

Hi Peter,
Are the stand alone versions available for viewing? Wonderful image. Looking forward to see more from the new scope.

This photo reminds me of the first time I trained with black belts - and thought I will never be that good! Simply stunning capture and processing of a challenging target. I'm in awe!

I was surprised to see this one back at the "top of the pops" but thank you for your comments. BTW I trained in Wing Chun in youth...got my butt kicked many times while learning the art, grasshopper :)



Ta Louie!



Thanks...there is a h-alpha image from my RC on the Web somewhere....
