This is the stack of 15 hours and 10 minutes from the city centre of Belo Horizonte. A pretty polluted sky for such a hard DSO.

This Radio Telescope is one of the 23 dishes that make up the CARMA array.
(Combined Array for Research in Millimeter-wave Astronomy)
Primary science areas include: the formation, evolution, and dynamics of galaxies, the formation of stars and planetary systems around other stars, the composition of planetary atmospheres, comets and other small bodies in our Solar System, and the evolution of galaxy clusters and the Universe.
Tech info: Canon 6D, 24mm f1.4 stitched panorama.

Caption: Some targets for astronomical investigations are only visible from the Earth's southern hemisphere. This photo of the southern sky, taken at Cerro Paranal in the Chilean Atacama Desert, shows a total of three galaxies: stars and gas from the inner Milky Way and the two Magellanic Clouds. The Large and Small Magellanic Clouds, two dwarf galaxies accompanying the Milky Way, are both targets of the first science flights of SOFIA starting from Christchurch, New Zealand.

Caption: I wanted to share some of my recent landscape astrophotography with you that have been featured on Space.com and a few other science websites and social media pages - they have gotten a tremendous response & traffic from the public. I've sent a few emails to APOD but never heard back from anyone. If any of these images interest you, please feel free to get back to me so I can give you all the EXIF data and other pertinent information. Thank you for your time.

Caption: a close-up of Rho Ophiuchi region. Lots of gas and dust - all sorts of nebulas can be seen here and a globular cluster as a bonus. One of the most colorful and photogenic regions of the sky, for sure. This image was taken in the city of Gonçalves, Brazil with 3 hours of total exposure time. It was used a 5D mkII camera in a William Optics 90mm apochromatic refractor.

Caption: In the first one (Photo1.jpg), we can see the slopes of Mauna Kea at the bottom right, Hulalai volcano at the bottom left-center, the zodiacal light, Venus (low on the horizon), the remaining light of the setting Sun and (if you look closely on the left near the horizon) air glow (or night glow) as a greenish diffuse light. At first, I tought that the green was a fluke of my DSLR but a few minutes later I took a picture of the Milky Way (Photo2.jpg) and you can clearly see the green air glow low on the horizon.
Both pictures were taken on the slopes of Mauna Kea at 2800 meters (near the Onizuka Center for International Astronomy Visitor Information Station) on July 9th 2013 with a Canon 60D and a wide angle lens. Both are 30 seconds exposures at ISO 3200.

Caption: Here is the first object I have been able to target with my RCOS in Australia and my CDK in the US; and I am so pleased with the result.
Of course, being able to gather data from two telescopes means heaps of data has gone into this. I used the far superior conditions in California to get the luminance (mostly) and the my telescope in Australia for the colour (plus a few hours luminance).
Consequently, this HaLRGB image comprises 5:17:4:4:4 for a total 34 hours.

Caption: It is a delightful southern skies object - The Butterfly Cluster (M6) in a generously rich area of sky. It has an uncertain but lengthy history of observation being attributed by some to Ptolemy in the 2nd century AD. This image taken with a Takahashi BabyQ with reducer at an effective focal length of 328mm in LRGB (60,45,45,45) with Astrodon 2C filters and an ATIK 4000LE CCD. This is a widefield presentation hopefully giving some context to the subject in a FOV of about 2.5 degrees square.

Caption: Well this is not an astrophoto but if the Cassini probe could zoom in on Croatia, here's how we would have looked while it was taking an astrophoto of us! It was great fun and an incredible feeling knowing WE are going to be in one lonely pixel somewhere in that picture...
We had some clouds but still managed to observe Venus, Saturn and the Moon. The little girls enjoyed it too - my daughter Una (5.5 years old) and my friends daughter Dora (6 years old) were having fun and managed to stay awake to wave at Saturn

Taken from Zagreb, the capital of Croatia

Caption: Excellent seeing here last night allowed a fine view of Saturn to coincide with Cassini's much talked about Saturn/Earth portrait shot. This image was taken shortly before Cassini's photo run. Some faint diffuse spots can be seen on the disk but otherwise things look quiet.

it got humid/hot and the fireflies came alive again, so was out Thursday July-12-20123 night.
Via http://aa.usno.navy.mil/data/docs/RS_OneDay.php

12 July 2013 Eastern Daylight Time

SUN
Begin civil twilight 5:35 a.m.
Sunrise 6:09 a.m.
Sun transit 1:41 p.m.
Sunset 9:13 p.m.
End civil twilight 9:47 p.m.

I started imaging at at 10:28pm, 75 minutes past sunset, and took images till 1:12am, about 2 1/2 hours worth.

Each image is 15mm, 20 sec, ISO800.

Image#1: Here is that rough composite of all 460 images, using StarStax.
I like the bright sky still showing star trails with so many fireflies.

Image#2: Then trying to get the sky darker used images from 10:42pm

Image#3: Then trying to get less clouds used images from 10:55pm

Image#4: and finally wanting just dark skies for clear star trails, used images from midnight

YouTube time lapse video Fireflies and Startrails 7-12-2013 , 2 hours of images in 14 seconds, with music

Click to play embedded YouTube video.

The skies were clearer Friday, so I was out againout again, trying to capture maximum fireflies and startrails w/o clouds.
Another hot and humid night July-13-2013 Saturday, so I captured star trails and fireflies from a different angle, our driveway end

YouTube video for this as well

Going frame-frame thru the images in this stacked photo taken July-13-2013, originally posted above

I noticed 4 meteorites - looks like 1 exploded?
(the meteorites differentiated from fireflies via the classic colored streak indicative of material heating up)

I'd like thoughts of others here before going "public" outside of this expert group.

#1, full image with what I think is an exploding meteorite.

#1 crop, looks like it skipped the atmosphere twice and then exploded brightly?

#2 full image

#2 crop

#3 and #4 smaller, shown only as crops

Full resolution

Barnard 344 is a dark nebula in the constellation of Cygnus. It’s located close to the star Sadr in the Gamma Cygni Nebula. Barnard 344 is located on the bottom of the image.

This region is very rich of dark and emission nebulae. On the image also VanDenBergh 130, a reflection nebula in this region, can be seen. LBN234 is an emission nebula glowing with hydrogen and sulphur.

The image shown here is very different from the ordinary images that you often see of nebulae because this image is fully taken in the deepred part of the spectrum. Images were made in Hydrogen-alpha (656nm), Sulfur (673nm) and Near-infrared (>807nm). They were combined in a Spitzer satellite like palet that is often used for infrared imagery.

Near infrared = red
Hydrogen alpha = green
SII (sulphur) = blue

Telescope: TEC-140
Camera: QSI-583
Mount: Skywatcher NEQ-6

H-alpha: 6 x 1800 s (3nm astrodon)
SII: 3 x 1800 s (3nm astrodon)
Near infrared: 4 x 300 s (Baader 807nm Ir-pass)

21st July 2013 - A moon halo forms over the north western coast of the island of Moorea in French Polynesia. Moon halos are formed when light refracts through high altitude tiny ice crystals. The crystals have to be oriented and positioned just so with respect to your eye, in order for the halo to appear.
