Dear group,



Here is a rarely imaged Seyfert galaxy only seven arc-minutes away from bright Mirach

(beta-And, mag 2.06) from last night:



www.perseus.gr/Astro-DSO-NGC-0404.htm



The result came out much better than expected, for there were strong winds and I purposely

did not stick around for very long therafter so as not to endanger further my equipment.



Clear skies!



Anthony.

Thanks Chris and Stuart.



Chris, the source of the problem seems to be coming from the vicinity of

the bright carbon star at bottom-center. I will sit down tomorrow and

reprocess everything from scratch. The histograms are balanced and, in

fact, I very slightly clipped the green (on purpose) in order to

mitigate the green.

I was just being critical, perhaps a bit too much.. I think it is a fine image.

Chris,



Rest assured all feedback is welcome. I just reprocessed the image from

scratch and it seems the background normalization is the sticking point.

Anyway, I sincerely believe the new result is now much better.



Pats on the back are nice but good feedback is even better and I thank

you for making the point which also bothered me originally and which you

confirmed.



Anyway, I hope you find the new result more pleasing to the eye.



Anthony.

Sujet : [ap-ug] NGC 752 - Open Cluster in Andromeda





















Dear group,



Cat and mouse games last night with the partially-clouded skies and

where I managed to capture NGC 752 in Andromeda. This particular cluster

is very old for an open cluster (1.6 billion years-old) and spans 50' in

apparent diameter. It is wel-populated and provides for a most

impressive field of view.



For a result based on two hours total exposure time, please see

www.perseus.gr/Astro-DSO-NGC-0752.htm ... the image is

hyperlinked and which leads to an even more impressive higher resolution

version.



Transparency this evening is so-so for now but I hope to pursue the

Perseus Double Cluster around midnight when the skies are usually darkest.



Anthony.

At this year's AIC some of you may have seen me sitting at the back of the room during the various workshops and presentations. "He's probably hoping to catch some zzz's" you may have thought, but I was paying attention.

Well, truth be told, there was one presentation where I started nodding off, but I was continually awakened by the audience chanting "BEFORE!" and "AFTER!" along with Dr. Tom "Say it with me now" Davis.

I was, however, awake and enthralled by the workshop of the PhotoShop guys, Aravind Krishnaswamy and Alan Erickson, who showed a technique for making three dimensional animations of astronomical images.

Until I can reconfigure my computer to better make these videos, I'd like to share a short (5 Mb) 'proof of concept' movie with you. I believe it is best viewed with FireFox or Explorer.

Hello APUG,

Finally got my new AP130EDF GT out under the pristine skies of Spruce Knob back in August. The first night at the AHSP I found that the 20 mile an hour wind gusts were a bit much for the AP130 and the Mach 1 at full focal length. The next night the winds abated a bit and permitted full focal length and focal reduced imaging. I just finished processing my first image from the trip of our old friend Andromeda Galaxy.



I never tire of revisiting this galaxy with new gear and new optimizing techniques. I do optimize each image for printing so the web is not my final presentation goal.



Image specifics:

AP130 EDF GT with AP focal reducer

AP Mach1 GTO mount

Modified Canon T1i camera

A little under two hours of exposure data

Subs were mostly 5 minutes at ISO 1600 with a few 10 minutes at ISO 800

No darks or bias frames

A flat was applied in Photoshop

Optimized in Light Room and Photoshop

Stacking with Deep Sky Stacker



Just another interpretation of an old friend. Hope you enjoy and thanks Roland and the gang for making such enjoyable equipment to use.



Please click on all images until you are at the black portfolio viewing screen for best presentation. Thanks.

Jeff, so great to see this post from you! I love the rich vibrant colours, the framing and the way you've brought out the detail. The only slight quibble might be that the upper right edge of the galaxy seems to run a bit to purple but it is subtle. In any case, it is a superb shot!

Thanks Stuart! You are correct! I struggled with that, but some fresh eyes and a new approach this morning I think I have it corrected a bit. That magenta can get in the way sometimes. Thanks for the kind words and the good eye. I think I have a much better image now. Take care.

Dear group,



An opportunity to pursue an exoplanet transit for HAT-P-32b in And last

night and which was only announced June/2011.



This is find is the most inflated "hot Jupiter" discovery so far.



www.perseus.gr/Astro-Photometry-HAT-P-32-20120912.htm



The result came out much better than I expected and in spite of the fact

both the transparency and humidity were variable throughout the session.



Anthony.

Ahhh, incredible. I downloaded the large version 20.06MB and noticed several globular clusters scattered around the image. Within a few seconds I had the "massive" jpeg on the way and after scrolling around it for a while decided that the massive tiff needed to take up some drive space here as well. This is, without a doubt, to me, the best photo or mosaic of photos the Hubble has taken. It brings home the fact that the Andromeda Galaxy, M31 is a galaxy just like our home galaxy. It is a photo which looks almost exactly like we are looking along the arc of the milky way from Sagittarius outwards. Stunning and humbling.

Can anyone estimate the resolution in the image?

E.g. 1/1000 arcsecond per pixel.

Since my observatory is now embedded in severe light pollution, I have taken to imaging in narrowband. here is an image of Andromeda Galaxy in H-alpha. It shows a nice ring of hydrogen "flowers" around the periphery of the galaxy. 10 x 15 minute exposure with 130EDX refractor at F4.5 on a Mach1 mount.��www.buytelescopes.com/content/images/thumbs/0066641_andromeda-galaxy-in-hydrogen-light.jpeg

Hi, Roland:

I'm not an astro-imager, but this is the kind of image that makes me want to try my hand at it! Breathtaking. I love the richness of black-and-white luminance.

May I ask what kind of camera you used, and (this question definitely pegs me as a noob), is this a mosaic or a single wide-field composition?

It's a single wide field image taken with an SBIG STL11K camera, which has a full frame 35mm chip. The filter used was a Baader Planetarium 7 nm H-alpha filter.��Rolando����-----Original Message-----

Rolando,�������� Nice image, but there seems to be a conflict in yourstatements about exposure. If it was a .single.
