M16 The Eagle Nebula Toward the Center of Our Galaxy. It's a crowded neighborhood as you look toward the center of our Milky Way galaxy. Stars everywhere. But a timed astrophotography image will reveal M16, the Eagle Nebula.

This image was produced from a stack of exposures captured at a Bortle 4 site in Landers, CA, USA on a New Moon night. Telescope: Explore Scientific ED102 FL 714mm F7. Guiding was with an Orion 50mm Guide Scope FL 242mm, and a ZWO ASI290MC for the guide camera, and with PHD2 auto-guiding software. Mount: Celestron Advanced VX. Main imaging camera: ASI294MC PRO cooled to -5C. Exposures: 124 x 45s with Gain at 280 and Bin 1 x 1. No darks, flats or bias frames. Processed in PixInsight. Slight crop. Polar alignment was with SharpCap Pro.

This was an experiment using short exposures with high gain. Many use this technique and get good results. It seems to be a quick way to negate bad, or no, auto-guiding. But I still prefer to use exposures of 180s-240s, or even 300s for most targets like this.

The Dumbbell is the remnant of a dying star which collapsed but left these glowing gases some 15,000 years ago. Visible through small telescopes as a grey bowtie or dumbbell, astrophotography reveals the bright red and blue regions and shows the full structure to be more of a football shape. I have been chasing this nebula all summer as a target for live outreach sessions in New York City, but shot this version from home, 10 miles north of the city line.

Tech Stuff: Borg 71 FL lens on ZWO ASI1600MC astro camera mounted on unguided iOptron CubePro mount. Image integrates 6 SharpCap LiveStacks of 4 or 8 second exposures totaling 77 minutes, processed with PixInsight.

NGC 891 is an edge-on galaxy 30 million light years out; it is said to resemble how our Milky Way would look from the side. This unguided image demonstrates that CMOS imaging using short exposures can provide nice results with less cumbersome gear than CCD long exposure imaging.

Tech Stuff: Questar 3.5" telescope at native 1570 focal length (f ratio 18); unguided Questar PGII fork mount. QHY163 mono camera Luminance only; integration of 5 SharpCap Live stacks of 8 second exposures totaling 49 minutes, processed with PixInsight. Imaged from my yard 10 miles north of New York City.

In questa immagine è ben visibile un gran numero di crateri di dimensioni molto diverse, tipico di questa regione situata nell'emisfero sud della Luna.

I crateri più grandi visibili sono: Tycho (diametro 85 Km), visibile su a destra nella foto, Clavius (diametro 230 Km), visibile a sud di Tycho e con altri crateri più piccoli al suo interno, Schiller (180 Km), che appare molto allungato a sinistra della foto, non lontano dal bordo lunare, Longomontanus (diametro 145 Km), visibile quasi al centro.

A star exploded some five to eight thousand years ago sending a ball of gas and dust out into space. Today the Veil Nebula can be found in Cygnus and is a great summer astrophotography subject. Here I have captured it using a new light pollution filter that helps bring forward the red (hydrogen) and blue (oxygen) features. The filter still allows the star field to come through, surprisingly dense for my suburban location 10 miles north of New York City.

On the morning of Friday 13th May my friend Stuart tipped me off that there was a huge looping prominence visible on the Sun. It was cloudy at the time but I could see a few gaps possibly heading my way so I set up the solar telescope just in case. What followed was a hugely frustrating imaging session, with strong gusts of wind and lots of cloud scudding past the Sun every time I started to capture video. My laptop screen also hadn't been fixed yet so it was incredibly difficult to get focus and exposure right. By the time I got a clear look at the Sun the large prominence in question had lifted off and vanished! However, I manage to get some ok shots out of the imaging session. My white light stuff ended up being horrendous so this collage is pretty grim! It's always fun to see the two lights side by side, so I'm sharing it anyway.

The Sun was playing hide & Seek with clouds today, but I managed to grab a few videos in the gaps so I could test out the new Baader Solar Continuum Filter that I bought from First Light Optics a few weeks ago. This filter helps to reduce the effect of atmospheric turbulence and I could definitely see that on screen. It also increases definition and brings out the granularity of the Sun's visible surface. I have wanted one of these for about 9 years so I'm super thrilled to finally have one! I'm looking forward to playing with it some more.

The Dumbbell Nebula (also known as Apple Core Nebula, Messier 27, M 27, or NGC 6853) is a planetary nebula in the constellation Vulpecula, at a distance of about 1227 light-years. This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arcminutes, it is easily visible in binoculars, and a popular observing target in amateur telescopes. The Dumbbell Nebula appears to be shaped like a prolate spheroid and is viewed from our perspective along the plane of its equator. This nebula is at most 48,000 years old, with many estimates placing it closer to the 10,000 year range! Prior to that, it was a giant star, burning through helium fuel in its core and hydrogen in its outer layers. When the core ran out of helium fuel, it contracted and heated up, and the elevation in radiation pressure first blew off the star’s outer, hydrogen-rich layers. In 1992, Moreno-Corral et al. computed that its rate of expansion in the plane of the sky was no more than 2.3" per century. From this, an upper limit to the age of 14,600 yr may be determined. In 1970, Bohuski, Smith, and Weedman found an expansion velocity of 31 km/s. Given its semi-minor axis radius of 1.01 ly, this implies that the kinematic age of the nebula is some 9,800 years.

The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792.[2] It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000[3] to 400,000[citation needed] years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.

(Source: Wikipedia.org)

Technical for This Image: NGC 6888, The Crescent Nebula, is a difficult target to capture. First, it is a faint nebula and requires a good number of exposures and integration time. Second, it is in a dense star field, so image processing to bring out the nebula's detail can also over-brighten the stars around the object. This image was captured with an Explore Scientific ED102 APO Refractor telescope. At the prime focus was a ZWO ASI294MC Pro camera set to 240 Gain and cooled to a temperature of -5C. Exposures were 140 x 45s each. Guiding was done through an Orion 50mm guide scope and a ZWO ASI290MC camera and was directed by PHD2 auto-guiding software. Image acquisition was through Astrophotography Tool (APT) software. Post processing used Deep Sky Stacker software for stacking and alignment of frames and Pixinsight and Photoshop software for all other processing. Polar alignment for the evening was done through SharpCap Pro.

Seasonal Favorite, remnant of a supernova recorded in 1054. First in Messier's great catalogue of Deep Sky Objects -- not because it is biggest or brightest, but because it was the first fixed feature of the sky he observed when searching for Halley's Comet.

Tech Stuff: Borg 71FL/1.08x Borg flattener/ZWO ASI 1600MC/IDAS LPS-V4 filter. Captured with SharpCap 3.2 as 4 second exposures collected in 4 minute livestacks. Total integration time 92 minutes, processed with PixInsight and ACDSee. From my yard in Westchester County NY 2 Nov 2019.

On a rare, clear and virtually moonless night, I decided to give my first try at the Rosette Nebula. This nebula almost filled up the entire frame - I never realized how big it was!

Still need to work on my noise ratio, add a field flattener and Ha filter to my process.

Object Details: For a few minutes on Wednesday evening November 2, 2022 Jupiter's moons Ganymede and Europa both threw their shadows onto the planet's cloud tops. I was fortunate to catch this event using one of the longer focal-length scopes.

The attached shows how it appeared in three different wavelengths. As noted on the lightness version of the luminance image, Ganymede's shadow was just rotating on at left, while Europa's shadow was just rotating off at right. The moons themselves can be seen to the right of the planet, while at left the moon Io hangs out and watches the show ;) .

At 3,122 kms (1,940 mi) in diameter, Europa is the smallest of Jupiter's four Galilean moons; while having a diameter of 5,268 km (3,274 mi.) Ganymede is the largest (and is actually bigger than the plant Mercury at 4,879 km (3,032 mi) ! ). Looking closely at the luminance image one can see the huge shadow of Ganymede appears elongated, lower-left to upper-right, as it falls upon the curved cloud tops of Jupiter's sphere.

As is often the case, the infrared image shows additional detail in the planet's cloud tops given that filter's ability to reduce the detrimental effects of poor seeing to some degree. As such many Jovian atmospheric phenomena such as festoons, barges, 'smaller' storms, etc. become more apparent in that wavelength. Being a methane blocking filter, Jupiter's moons, which contain little to no Methane, appear much brighter relative to the planet itself in that filter's image.

Image Details: Taken by Jay Edwards over the course of approximately 15 minutes on the evening of November 2, 2022 (UT date of the 3rd) from the observatory I built at my home here in upstate NY; the data making up the attached composite was acquired using a vintage 1970, 8-inch, f/7 Criterion newtonian reflector and a 3X Televue barlow connected to a ZWO ASI290MC planetary camera / autoguider. As is often the case here the camera was controlled by SharpCap Pro & the scope was mounted and tracked using a Losmandy G-11 running a Gemini 2 control system.

Each image is a stack of several hundred frames selected from video clips which were kept fairly short due to Jupiter's fast rate of rotation. Since humans tend to see detail in an image via it's contrast and brightness, as opposed to it's color, I have extracted the lightness channel from each image and placed them in the second row. As shown here the data have been processed using a combination of Registax & Paint Shop Pro, and the entire composite has been resized down to 50% of it's original size.

I was able to capture additional images that evening both prior to and following this event, although I have yet to process any of it. Given that a quick look at the earlier shots appears to show that they may picked up the disk of Ganymede itself as it transited Jupiter earlier that evening, I'm looking forward to seeing what I can pull out of the data.

Wishing clear, calm & dark skies to all !

The night of 6th-7th August was very clear in London So we thought we'd image some planets for a change. At this time, this year, Jupiter, Saturn and Mars are well placed for imaging although Jupiter and Saturn are very low in the sky. Jupiter reached opposition on July 14 this year so in this shot it is no longer as impressive as it was a couple of weeks ago but it's still big and bright enough to be interesting to image. We took numerous shots at different gain settings and exposures and this is the first image that I'm happy with but there are still lots more to process. This is a composite shot with the moons taken from another video, stacked and placed in the correct positions. Europa is on the left and Io is on the right. The final picture was resampled to make it larger while maintaining quality.

Saturn is at opposition with Earth on 27th June (this is when Earth is aligned between the Sun and Saturn and so is at its closest to the planet). This means that at a mere 1.2 billion kilometers away Saturn appears bigger and brighter in the night sky and it's the best time to image it. This image was taken on 23rd June, very close to opposition so much more detail is showing including at least three of its rings as well as the Cassini division. Also visible is some of the banding in the planet's turbulent atmosphere caused by its fast rotation of 10 and a half hours. This image has been cropped to enlarge the features.

La V lunare si forma a causa della luce solare che arriva radente sul cratere Ukert (diametro 22 Km) e su alcuni crateri più piccoli nei dintorni. Come per la X, la V è ben visibile per alcune ore quando la Luna si trova in una fase prossima al Primo Quarto.
