I Like the shells around 6164, I've seen them before but not in narrowband that I can remember. Good to see you putting the new scope to good use.

Mike just wanted to see what faint detail you could capture where my image was effectively black. Narrow band does give an indication of where the dust is as it modulates the emission brightness by attenuation. I made the gif for that so it was just as easy to post it. I also wanted to get a visual idea of the huge field you have for the focal length you have. A picture is worth a thousand words. It also shows me what I am failing to record.

I missed this animation before Bert - sure is a good advertisement for the extra detail NB can bring out (when processed well with great data too of course)

strongmanmike (Michael) · #44 23-05-2011, 02:44 PM

Oh I see Bert, fair enough, it's reasonably revealing but the comparison was with a much smaller instrument, that was all.

Cheers Clive, yeh, the new scope is pretty good really.

Around here my 'instrument' is considered quite large Mike. Although I did not know we were playing in a cathedral!

gotta love Billy!

Loved the hi res Mike, outstanding considering you were working under Newie skies... that, you gotta love NB imaging!

I do love narrow band provided the palette is tasteful.
This is certainly one area that just screams for narrow band and you've done a great job showing some really tantalising areas!

I wasn't aware that NGC 6164 and its Wolf Rayet star had this ejecta bubble.. exquisite!
Also great orientation to get the extent of Ngc 6188's 'Wall' in as well...

Well done Migel!!
And a well deserved image of the week!

All the best
Rich

I think this is an amazing image but I also wonder how it all comes together. 6 Hours worth of imaging in one night, 6 different channels of data, some fantastic imaging equipment and I am asuming amazing processing skills. God I wish I had that ability. I looked at this last night in amazement that an ammature astronomer is producing images that if I showed someone they would probably think the Hubble telescope took it. I am rabbiting on now but I am honestly blown away. Well done and if you ever need anyone to make you coffee on a night when you do some more imaging let me know and I will come down from Queensland as long as I can watch you process it as well. Average seeing. Can you imagine if it was good.

Nice work Mike....the expanding shells look great.

Peter Ward · #51 23-05-2011, 06:07 PM

Resolution wise...looks a little soft to me....and welcome to the club... I've come to the conclusion any aperture over 20cm gets hit by seeing more oft' than not.

I do like the capture of the halo around NGC6164... a hard sucker to grab from the 'burbs (i.e. my neck of the woods) at the best of times.

Very nicely done

TheDecepticon · #52 23-05-2011, 07:31 PM

Congrats on a great image!

I know you were doing it from a very polluted site, however, your stars don't look quite right.

I would like to see what you can get with this setup from a dark site, however, I still think your AP refractor images are better.

New scope and all still, so can't wait until you settle right in.

Cheers,

Gray.

avandonk · #53 23-05-2011, 08:05 PM

I promised myself to never ever have any words to PW ever again. But I will now digress.

You say the image is soft peter? Compared to an f/10 RC?
A very stupid comparison.

Seeing has nothing to do with aperture. Another myth!

I will hate myself in the morning.

Pure BS Bert.

You are confusing visual observation (aperture wins every time) vs imaging conditions (why the pros are located at Mona Kea/ Chile etc. )

I can take images of needle like stars night after night with a 55mm Takumar lens, and never know the concept of "seeing"

Take it with a 300mm aperture.....and Mona Kea starts to look like a good retirement option.

Kal (Andrew) · #55 23-05-2011, 08:30 PM

What a treat to view, thanks Mike!

alan meehan (Alan) · #56 23-05-2011, 10:26 PM

Mike what a wonderful shot you give me hope that there is something to view in our newcastle skies

Thanks again guys for all the nice comments

Things are progressing nicely with the scope, as has been mentioned it is a new scope and no unpack and play APO here...I already have one of those

...this is a light collecting Hoover but needs more patience, bit like a Ferrari, a touch outa tune and it may as well be a Commodore (still a nice car)

Hi Mark

Very gald you enjoyed the image so much.

As a portable imager, who sets up for each session, the biggest attraction for me to go with this AG12 was the opportunity to take full LRGB or SIIHaOIII deep images in a single clear night. Although a razzor sharp peformer, the Starfire with it's miserly 6" of apperture and slow F8.3 focal ratio made completing deep images in a single night basically impossible. Having to come back and do it all again another night on the same object was rather off putting at times.

Sure there is a bit of work composing an SIIHaOIIIRGB image but the results are usually worth the effort and under city skies is often the only option especially with a moon in the sky.

You are welcome to come and do an imaging session, if you are ever in Newcastle get in touch. As for watching the processing ...the Fighting Dragons image took basically an entire day to compose..with a few breaks thrown in of course, so you may get bored watching me process

Hi Richi poo

So happy you liked the image mate. Your recent, more traditional version of the wall was a mighty fine image and I enjoyed it very much too

A fast Newt is pretty cool huh?..with a Sao biscuit sized chip at the focus it provides so many options too

Mike

Tandum (Robin) · #60 25-05-2011, 12:26 AM

Stunning image mike and all in one night. I've been plugging away at this one as well, after doug's post and when weather permits, with a 102mm F6 refractor and 20min binned x2 subs are short on data

You've got me looking at low F reflectors again
