M1

Posted By dietmar hager

once more hello in this fading year 08!

this is hopefully not gonna be the final version of my M1-rendition, as I hope next year provides me with better seeing conditions, and more clear skies basically.
if so, I will be able to replace the data I had to play with this time:
one shot color data from 2 years ago (3 hours)
Ha, O3, L and rgb under low-quality seeing condtions from a couple nights I imaged recently in.

please find all data and the images here.
there is a lso a link to the older OSC-version for comparison.

hoping the very best for all of us!
yours,

Color Processing

Posted By dietmar hager

hi guys,

this is supposed to maybe help all those, who are not (yet) perfectly familiar with color-processing.
I think it might be an idea of how to preserve the colors while streching the color-image in Photoshop.

I apologize if this is an old hat...

M 81

Posted By dietmar hager

hi guys,

I have gotten featured at Universe Today with one of my recent images.
Also Karel Teuwen's image has been chosen for the overview.
Just another great collaboration so to say.

the close up on M81 was taken with my belvoed 9" TMB Apo at f/7 using a televue reducer; collecting 8.5 hours of total exposure time.
please find all data and images here:
http://www.stargazer-observatory.com/m81.html

here is the story by Tammy Plottner where you will also find Karel's gorgeous image (again):

CEDIC - Central European Deepsky Imaging Conferenc

Posted By dietmar hager

hi guys,

on behalf of the organizers I would like to draw your attention to the first central european imaging conference for deepsky photography:

Calling all astro images!

We would like to invite you to the "Central European Deepsky Imaging
Conference"
(CEDIC'09), which will take place from Friday, April 3, to Sunday, April 5,
2009, in
Linz, Austria.

CEDIC'09 is the first international astro imaging conference in Europe. The
agenda
of the meeting, and many more details, are available at the CEDIC web site
at

http://www.cedic.at

Registration for the conference is also possible on
this web
site. Please note that the number of participants is limited, so please
register
early.

Among the many talks schedules for CEID are "The ESA/ESO/NASA Photoshop
FITS Liberator - in depth!" von Lars Lindberg Christensen (ESO/ESA) and
"Astrophotography at Paranal: from a DSLR to VLT" by Yuri Beletsky (ESO), to

name only two of the highlights. Many more interesting talks by leading
astro
imagers, presentations of the newest astro imaging hardware, a conference
dinner
in a relaxed atmosphere, and a opening event featuring top astro images in a

breathtaking gigapixel projection will make CEDIC'09 an event not to miss!

Please note that the city of Linz is also the European Capital of Culture in
2009.
So much more waits here for you to be discovered, besides CEDIC.

Conference language is English.

UNIVIEW and more

Posted By dietmar hager

dear group,

...various reasons kept me from taking astro-images lately and here is some explanation for being out of the lop for such a long time.
for those who find time to read this:

1.) I have met and discussed with decision-makers of politics and economy, have them “embarque the boat” of light pollution campaigning. Also I have met the heads of the 3 largest public housing associations (being in charge of about 60.000 inhabs of Linz) and the advocate of environment and the president of federal government.
I have spoken at schools, universities and public educational environments about light pollution and astronomy per se.
I have collaborated with Thomas Posch, chair of the Austrian board of IYA 09 in all this matters, of whom I was privileged to represent at all those meetings.
As a consequence, the local and regional government have decided to pick up light pollution as a priority topic. Thes have commenced forming work-groups and they are about to think of ways, to decrease public illumination and make a change.
I was invited to lead the restoration of a very famous and renown school’s astronomical observatory (Petrinum). They now have Austria’s very best and highest sophisticated telescope in a 15 feet fully robotic dome with remote capability. (the scope is an 8 inch triple-apo f/9; TMB design, one of the very last on earth...).

2.) Last night we had the grand opening of the astronomy-exhibition at AEC, the Ars Electronica Center in Linz, which I coach as an advisor and counsellor in astronomy-projects.
http://aec.at/news_en.php?iNewsID=1183

15.000 visitors a month will now see
- moon-meteorits with microsurgical headmounted microscope (which I use in my day-job as a microsurgeon),
- mars meteorits
- steer around a mars-rover, and wear space-suits (provided by the Austrian Space Forum (Gernot Grömer))
- learn about ligh pollution, Apollo landing, Paolo Salucci's research in dark matter, see lots of HD-rendered 3d videos of the surface of Mars and the moon.
The ultimate feature but is the following:
- see the UNIVEW software application in 3d stereo presented in the “deep space-room” of the AEC: The technological heart of Deep Space consists of eight 1080p HD- and Active Stereo-capable Barco Galaxy NH12 projectors. The images are projected onto mammoth 16x9-meter displays mounted on the wall as well as in the floor. A great vantage-point view and a dizzying shift of perspective is available from the Deep Space Platform set up at an altitude of about five meters.
The technology installed in Deep Space makes it possible to produce uniform displays with a resolution measuring 2,160 pixels high and 3,840 pixel wide. Through the use of edge blending, the images projected next to each other on the wall and floor can be merged together pixel by pixel until the areas of overlapping are ultimately undetectable.
Uniview:
http://scalingtheuniverse.com/

By means of this unique application, we let our guests see the
- magnetosphere of earth in real time,
- let them take a bath in Saturn's rings,
- let the planets spin around the sun seen from different angles
- displayed the Oort cloud, the radio sphere, the constellations and change of shape when switching angle of view
- showed them the exoplanets
- the scientific probes yet started with their past, current and future position
- how far we earthlings can reach out with bare eyes,
- let them see our galaxy and far beyond,...
- see lots of ESA and NASA HD renderings of lunar and Mars’ surface, explanets, center of the galaxy with stars spinning around the black hole and much more.
AND all of this is presented in 3D STEREO (shutter glass technology) !!!
It was a tremendous show! I wish you could have been here to see for yourself.
At present, the AEC is the only place on earth, the uniview-show can ne watched in 3d stereo.

Also, we will celebrate the 40 year anniversary of manned lunar landing, having Shane Campell here in a skype-life-session for example.

3.) On the 3rd of September we will run a big star party on the main square of Linz, expecting some thousands of people come to peek at the stars, after the major of town will have switched off all lights at night. This way the major will be in charge to let his agreeing words follow deeds. But he has understood, it is a chance for the city of Linz to stride along new ways and become a very good example in Austria.
A life con. to the ISS, ESO and Kitt Peak shall become some further highlights to the event. Also Franz Viehböck (late Austrian kosmonaut) will come to speak about his enterprises in space.
By 10 p.m. the major will switch off the light and people will gaze into the night skies, looking through some dozens of telescopes, my amateur collegues will set up.
Also there are gonne take place work-shops for kids.
I am cooperating with UNESCO-schools and have their students come to the AEC and guide them through special shows, dedicated to kids.

This entire "star-party" event will take place with the grand opening of the Linzer “Klangwolke”.
http://www.aec.at/humannature/index_en.html

in case, you are intrested in seeing the 3d stereo show, drop me an e-mail, guys.
once my schedule opens a window for astro-imaging, I shall post such image here.

Meanwhile, I send you heartiest greetings from Austria,

Dietmar

M27 imaged with a new brand of 4 inch apo

Posted By dietmar hager

hi guys,

I am getting back here after a long pause, due to various reaosns.
more than half of the year has passed without imaging, I am afraid...

APM and TS asked me to test a new brand of air spaced triple apo, which comprise a TS-focuser.
this scope is 4 inch f/6.5 triple apo, housing lenses not being designed by TMB and not manufactured by LZOS.
still, visually the apo displays stars pin point like, though there is a difference that is noticable to any experienced TMB guy like me...

this image renders a FL result of this nice scope.
find all data on my website:
http://www.stargazer-observatory.com/M27-4.html

NGC 6888 first light from TAO

Posted By dietmar hager

hi guys,

atfer a long pause of posting astrophotos to this group I am very glad to crank
out another image, which represents something very special for me:
the first light result of TAO: triple apo observatory.

TAO is a collaborative project I run together with my close friend Immo Gerber.
We have decided to share equipment and time in future. therefor we now own a
remote observatory in the southern parts of france, which provides very dark
skies sparing us from any sort of light-pollution.
TAO is member of ROSA. a remote observatory park in southern france which was
given birth to by our friends Daniel Marquardt and Karel Teuwen.

as we have raised the obs in late april we have become fully operational in
about May this year, commencing data-aquisition at once.
after some time of experiments and adjustments we are now happy to present our
first light result.

The object of interest was the crescent nebula.
quite a demanding object I hear you say, more so in regards to the fact we did
not have an O3 filter available.
fearlessly we rushed into this and what you will see renders mostly LRGB with a
deep set of HA, though.
surprisingly enough, the color-data held enough of of what we did not expect to
see at all – the area of the nebula which is usually demonstrated in O3 !

enough words for now – please find all data on the website.

thanks for looking and comments are gladly appreciated!

and the best of it:

NGC 660

Posted By dietmar hager

hi guys,

here is our second image from the new remote observatory in south of france.
the first light has been shown a couple months ago (ngc 6888).

this time, our target was NGC 660. not only because she is a brilliant and intruiging polar-ring-galaxy, but also the field around her has a great deal to offer.

Immo and me, we hope you do enjoy the result:
