I like how you can just make out the homunculus amidst the glare. Nicely done! :-)

You have a keen eye...it was indeed intentional

Many thanks to all who have responded on this one...it's quite overwhelming and a good motivator for yours truly to explore similar options

I have been back to this a few times and looked over the image a lot. This is my prediction. If you enter this in the Malins, this looks like the overall winner to me. Sure its a well imaged target but it surely has to be the sharpest image of this target ever submitted. Not to mention the colour being very pleasing. Anyway just my thoughts.

Hi Paul,
It's incredibly sharp -
maybe the best picture ever taken in Australia?
It must have been a lucky night with sub arc second seeing?

cheers

Very kind of you, but I don't think I'd go quite that far

Thanks Paul. I wouldn't at all be upset with your prognostication

but the Malin's are so hard to predict.

I will say this much, widefield and often very colourful DSLR vista's are often stunning or very pretty...but as there so many of them, I felt a void was being created in...dare I say "traditional"... long focal length, high resolution deep-sky images.

Getting tight, high-resolution stars is no trivial task and I hope images like this gain some popularity in the future.

*wonders if he can do it with his 5" refractor*

I submitted nearly all long focal length this year, with only one image being wide field. It will be a tough competition for sure and now that wide field and narrow field are together once more it will be all the harder to win.

Incidentally what speed were you guiding with on the AOX? There are a few bright stars in that region and finding a bright guide star can be a problem sometimes but not there I think.

Hmm certainly very sharp but can it be the best picture taken in Australia? With a few really sharp images myself and knowing there are few others out there with really sharp images of various targets it might be hard to call. Personally I would not like to say its the best but it certainly is a very nice image and one I would be very happy with myself.

Hi Paul,.
can you show me a link where say the keyhole nebula is sharper taken from any Australian telescope?

Only the CHART 32 image from Chile can beat it - from any image I can find.
see here:
http://www.chart32.de/images/phocaga...r_sho_c200.jpg

I wonder what Peter measured as his FWHM?

cheers

I thought you meant any image taken of any object. You did say the best picture taken in Australia. Hence my comments.

Make it any deep sky object then except -
it's hard to compare unless you use the same object.

I recall it was fairly fast...8-10 Hz for RGB and 3-5 Hz for the H-alpha ...or there abouts...I didn't record the actual numbers.

Well that full-res view triggered a sharp intake of breath! Saw that you'd got the APOD (many congrats, nice to see an APOD from Sutherland Shire!) but was blown away by the details you've got once I had a good look, especially around the Bok Globules. A really special image

AstroJason (Jason) · #53 29-05-2016, 08:01 AM

As many have said, APOD well deserved. That is one incredibly detailed shot, Peter. Amazing stuff that!

Thanks gentlemen...again the feedback on this one has been quite amazing.

Rather than thank you all individually from here (unless you have a specific question) I'll put this one to bed now .... going to the "top of the pops" just needlessly takes up bandwidth at this point.

Clear skies!

Octane (Humayun) · #55 30-05-2016, 10:24 AM

That is quite simply one of the finest images ever posted on this site, perhaps /the/ finest image ever posted here.

I've been procrastinating building my observatory and seeing this makes me procrastinate more; what's the point?

Congratulations on the APOD, too!

Flugel88 (Michael) · #56 30-05-2016, 04:10 PM

Wow Peter the detail is insane very immersive.
The natural colour even with Ha added is superb.

IanP · #57 30-05-2016, 10:08 PM

Peter, this is well deserved NASA APOD, congratulations !!!

Hi Octane,
I want to build an observatory too - one day
but I will try not to let this put me off.
Peter is using extremely expensive equipment & adaptive optics.

When you see what Oleg Bryzgalov is managing to do in the Ukraine
it will give you inspiration.
He is using a 10" Newt. with an observatory.
see here:

Of course Rolf Olsen is doing extremely well too without spending megabucks:

One problem is that a Newt. doesn't give you enough back focus to use adaptive optics easily.

cheers
Allan

DJT (David) · #59 30-05-2016, 11:52 PM

What a gorgeous image. The detail is awesome. Gotta love an iPad,

Kudos to those with the biggest and bestest toys. It takes some passion for this hobby to want to commit to that level in order to produce stunning images like this.

Well done

Octane (Humayun) · #60 31-05-2016, 10:09 AM

Hey Allan,

I've been doing this for over ten years now and I'm lacking motivation.

I've got an FSQ and an STL with no likelihood of any bigger/better toys for the foreseeable future. Multiple mortgages kills those prospects!

If I can get started on digging a hole in the ground in the backyard, I might progress.

I met up with Rolf a couple of years ago in New Zealand. I regret not being able to make it to his home to see his observatory.
