This was an alternate stack of the same photos using Sequator vs the previous using DeepSkyStacker. I like the results out of Sequator a bit better and the ease of use.

An untracked/unguided, short-exposure view of the sickle-shaped asterism in the constellation Leo the Lion. This asterism (star pattern) can also be seen as the mirror image of a question mark starting with the first magnitude star Regulus and looping around to the stars that form the lion's mane and back of head. I've marked the outline of this asterism with lines which are best seen in the full-sized image ("View all sizes" under the Flickr light box -- press the "L" key to toggle the light box).

 

This photo also captured the small, 9th-magnitude barred-spiral galaxy NGC 2904 which is identified in my picture entitled "The Constellation Leo The Lion And NGC 2903 (4 Second, Unguided Exposure Stack)."

 

Captured on December 4, 2011 between the hours of 4:54AM and 5:04AM PST from a significantly light-polluted, near-center-city location using a Nikon D5100 DSLR (ISO 3200, 4 seconds x 90 or six minutes total exposure integration time) and a Nikkor 50mm AI-S 1:1.8 lens set to aperture f/4. Image stack created with DeepSkyStacker (90 "light" frames and 30 "dark" frames) with final adjustments done in Photoshop CS3. Star diffraction spikes were added in Photoshop CS3 using ProDigital Software's Astronomy Tools.

First attempt at a stacked image, it's only 3x5s subs with 3x5s blacks so didn't expect much but got more than I expected. Gives a bit of hope for longer and more subs.

Comment

While on a long road trip (Seattle to LA), I passed through the relatively low population areas of northern CA, which also have low amounts of light pollution. The Milky Way was so clear I could see it with my naked eye while driving!

 

Stack of 7 shots using DeepSkyStacker

 

This is my first shot at the Milky Way; Im fairly happy with how it turned out. Its a bit noisy, but with a 20D at ISO 800 for 30 seconds its not bad. Next time Ill shoot more for better stacks...

M81 and M82 form part of the M81 Group, a grouping of galaxies located approximately 11MLy from Earth in the constellation of Ursa Major. A total of 34 galaxies have been identified as belonging to the group (see en.wikipedia.org/wiki/M81_Group#Members). For a higher resolution image of these two galaxies see flic.kr/p/dGoT2Y.

 

This image also includes two other members of the group; NGC 2976 and NGC 3077.

Reprocessed from RAW images instead of JPEG. Used bias, dark, and flat frames. I don't think it made much of a difference. I actually like the JPEG stack better. DeepSkyStacker seems to like my JPEG images better than RAW, I'm able to stretch them further in Lightroom with less noise and more color retained.

The hunter set, it was the scorpion's turn. 5am before dawn, the Houston sky was covered with haze; only Antares can be seen by naked eye. I managed to find a place on the balcony and fit (all but β Sco) the whole creature in the 28mm frame. The sky was so unevenly lit that I had to use out-of-focus pictures of the same view as the "flat images" to make the sky more manageable when stacked. The result was quite amazing as it managed to show stars up to mag +8 (+7 near the horizon) -- regarding the poor condition down in the town.

Really surprised how well I was able to keep the core from blowing out without taking multiple exposure lengths. I did process the same data twice, one to focus on faint detail and another focusing on the core, then combine them in the layer module in StarTools to get the final HDR result.

 

Plan is to add longer subs to bring out the fainter nebulosity more.

Ok, I've posted the Orion Nebula before, but nowhere near this detailed. This is a total of about 20 minutes of exposures, and combined with a really dark location, so much structure came out, I was kind of blown away. This complex is MASSIVE. Our entire solar system would be invisible if it were placed in the heart of the nebula. It's truly enormous. About 141,087,008,956,406 miles across. (144 trillion miles) This is how we know the process of star formation. It's happening right here in this image.

Mein erster Versuch mit der Astrotrac TT320X-AG Nachführung.

Die Astrotrac wurde auf ein Manfrotto 055XPROB Pro Stativ montiert.

Die Ausrichtung erfolgte mit dem Manfrotto Getriebekopf 405 und die Kamera ist auf einen Manfrotto Kugelkopf 498RC4 montiert.

 

Das Fotos besteht aus 4 RAW Einzebildern (plus zusätzlich 2 Dunkelbilder) und es wurde mit DeepSkyStacker zusammen gestackt.

Daten zu den Einzelbildern:

Belichtungszeit: 120sec.

Blende: f4,5

ISO: 3200

Brennweite: 182mm

 

Für die Aufnahme habe ich meine Canon EOS 7D und das Canon 70-200mm f2.8 IS II USM Objektiv verwendet.

Zusätzlich wurde noch ein Astronomik CLS Clip Filter eingesetzt um die Farben etwas besser heraus zu holen. Zusätzlich wurde das Foto mit DPP etwas nachgearbeitet.

I used my Canon EOS 7D and the Canon 70-200mm f2.8 IS II USM Lens.

Additionally i used a Astronomik CLS Clip Filter for better colors. The Picture was re-mastered a little with DPP.

A glowing donut of gas with a cluster of massive hot young stars in its core.

Bad observing conditions, lots of clouds. Luckily, there was a hole in clouds near Cassiopeia, so I could take this shot. Still, thin layers of clouds got in the way, so there's a haze over the comet itself.

From Wikipedia:

The Beehive Cluster, also known as Praesepe (Latin for "manger"), M44, NGC 2632, or Cr 189, is an open cluster in the constellation Cancer. It is one of the nearest open clusters to the Solar System, and it contains a larger star population than most other nearby clusters.

I now have a tracking mount, and after struggling a previous night with getting good images through the telescope itself, as well is issues with equatorial alignment, I went out again to do some wider fields with my camera lens in alt/az mode. This was shot at 50 mm on a Z6III (full frame), stacking 30 s frames to minimize frame rotation. It shows the "Double-Cluster" formation, and the Heart & Soul Nebula can be faintly seen amongst the mass of background stars. 22 frames were stacked in DeepSkyStacker to make this image, though it would have been 45 if not for a glitch in my interval timer setup. Exposures were 30 s, f/2.5, ISO 640.

This is a stack of 8 exposures of 30s each of the Cygnus constellation. The camera (Sony ILCE7) and the prime lens (Sonnar T* FE 55mm F1.8 ZA) have been attached to a "Star Adventurer"-mount in order to compensate for earth rotation, while shooting at F2.8/ISO 1250-1600. Stacking has been done with DeepSkyStacker, and final editing with Photoshop CC 2015. Hope for clear nights to come in order to test longer exposure times and focal lenghts.
