This is a small part of the Rho Ophiuci complex, a nice zone of the sky toward the center of our Milky Way galaxy. Within the image you could see dark nebula, dust clouds, star-forming regions and part of the reflection nebula IC 4603 (blue, to the left). Nefertiti's head or a dark angel, whatever you think of the silouette, has also interesting views rotating the image. TEC 140 refractor scope, camera Sbig STF8300-AO/8, 7.5 hours in LRGB exposure, 12 min subframes, from my backyard obs at La Colonia, Illapel, Chile.

The Seestar S50 started this image at 10:00PM to 3:50 AM. During this time 976 ten-seconds subframes were taken. Of those 865 passed muster. The images were pieced together as a mosaic. Image right annotates some points of interest.

LdN refers to Lynds Catalog of Dark Nebulae. What is a dark nebula? (Wikipedia: A dark nebula or absorption nebula is a type of interstellar cloud, particularly molecular clouds, that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains in the coldest, densest parts of molecular clouds.)

I started exposing this image at 11:05 PM last night and finished at 2:46 AM this morning. Even though that was about 3 hours and 40 minutes there were a few dropped frames and processing time which reduced actually exposure time to 2 hours divided into 10 second subframes. Below is a screenshot depicting a step in post-processing.

A collage utilizing both H-alpha and CaK imaging of our Sun. Subframe positions is "artistic" and does not represent correct orientation compared to Sun - all images are however taken by me excluding the Apollo era (free) picture of Earth showing approximate scale. Pictures taken in southern Finland during summers of 2016 and 2017 as I haven't had time to image at all lately.

See www.flickr.com/photos/130947324@N08/46483974944/ for labels.

Recorded with BW ASI178mm camera, colors added in post production. H-alpha images colored to red and yellow and they are partially inverted to pop out surface details, protuberances and filaments. CaK is colored to blue to mimic imaging bandwidth for CaK.

H-alpha: 656.28 nm (deep red in reality) hydrogen line. Tunable wavelength. Exposure times around 2 ms.

CaK: About 8 nm wide bandpass at the Calcium II K-Line centered around 395 nm (ultraviolet). Exposure time of about 0.8 ms.

Prefilter: Baader D-ERF (with H-alpha), Baader AstroSolar film (with CaK)

Scope: TS Express 80/480 mm FPL53 APO

Filter: Daystar Quark or Baader CaK

Camera: ASI 178mm with 0.5x reducer

DIY Arduino based focuser motor control

Mount: Celestron AVX (equatorial mount), StarAdventurer

Software: FireCapture, SharpCap, Autostakkert!, ImPPG and Photoshop CC.

Typically stacked a best few percents of 5000 images to create each of the separate photos. Full disk H-alpha sun is a composite of several sub images. I roughly estimated that I collected about 180 000 frames and 775 GB of uncompressed AVI video as raw material. Final stacked image number should be close to 4000 in that composite.

Abell 1367

Leo Galaxy Cluster

The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant in the constellation Leo, with at least 70 major galaxies. The elliptical galaxy known as NGC 3842 is the brightest member of this cluster. This is seen to the left and slightly upward of the center of the image. Along with the Coma Cluster, the Leo cluster is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, an immense galaxy filament which is hundreds of millions of light years long and is one of the largest known structures in the universe. The “CfA” designation refers to “Center for Astrophysics” redshift survey and was an attempt to map the large scale structure of the universe. CfA2 was the second survey started in 1985 and the Great Wall was discovered in 1989

The Leo Cluster mostly contains spiral galaxies, suggesting that it is much younger than other comparable clusters, such as the Coma Cluster. It is also home to one of the universe's largest known black holes, which lies in the center of NGC 3842. The black hole is 9.7 billion times more massive than our sun. (Wikipedia)

A window in the Roman Baths gave a cute street view.

This is a slightly different view of the Crab nebula. It is normally a narrowband target and scrubs up well in H Alpha. This mage is simply a colour image taken with a luminance/IR cut filter, giving a more natural view of the nebula. It is 20 individual subframes of 480 seconds each taken over two separate nights' observing in September and October.

I've seen the "Heart of the Heart" a million times so I figured I'd join the crowd. Actually this was a test- I've never tried to bin subframes in any setting other than 2x2. This was shot at 4x4.

Since I was able to image 3 times this week(a 1st in almost 2 years) I chose something familiar for my "binning" test, IC 1805, the Heart Nebula in the constellation of Cassiopeia.

Shot on 9/25 & 9/26/14 with a Celestron 11" EdgeHD @ F/7 and a QHY23M

RGB-10 subs each color filter/ 2 minutes each, 1hour total,4x4 binning

Ha,OIII,SII-10 subs each filter/5 minutes each,2.5 hours total, 4x4 binning

Figures walk through an arched frame, the glass doubling the movement. Reflections and strong diagonals pull the eye toward the light beyond. The scene holds close and quiet, a candid crossing turned formal by line and shadow.

I check my subframes before I do any post-processing. You never know what you might find, right?

Last night I captured the trails of a number of satellites. They are easy to explain (thank you, Elon, for ruining so many astrophotographs) But the three parallel bright lines are a complete mystery. Three somethings were moving slowly near M106 (faintly visible in the center), but not as slowly as the satellites. I also think there are vapor trails.

I can't figure out what they are.

This spectral shadowy figure is in fact the Cone Nebula that sits atop the Christmas tree nebula when viewed upside down. It looks more like a figure peering at the stars in the distance than a dark region where new stars have cleared pathways as they form.

This is a stack of ten ten-minute subframes in H Alpha.

Description:

The distinctively shaped M17 is a gas cloud of red ionized hydrogen on the northern border of the constellation Sagittarius.

From Wikipedia:

"The Omega Nebula ... is an H II region in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745. Charles Messier catalogued it in 1764.

The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars; however, the actual number of stars in the nebula is much higher - up to 800 ... plus over a thousand stars in formation on its outer regions. It is also one of the youngest clusters known, with an age of just 1 million years.."

The supercharged S-Type R (Jaguar STR for short) joined the lineup in 2002, and the hope was that it would compete with BMW's M5 and the Mercedes E55 AMG. The R was powered by the newly revised hand-built 4.2-Litre V8 with an Eaton M112 supercharger, producing 400 hp (298 kW; 406 PS) and could accelerate from 0 to 60 mph (97 km/h) in 5.3 seconds (0 to 100 km/h (62 mph) in 5.6 s). The top speed was limited to 155 mph. It included 18-inch (457-millimeter) alloy wheels, wire-mesh grille, and monochromatic paint. The R also has a rear apron, side-skirts, and front apron with built-in fog-lamps, a rear spoiler, a brace located near the rear subframe, and R badging on the boot lid and both front fenders (wings).

A late model Coupe which is the non-turbo model registered on the final day of 1999.

Fun fact about this car, it has failed every single MOT since 2006, or at least that far that records are kept online. Usual wear and tear items it must be said. The last MOT required front subframe welding to pass. But manages to still secure loving faithfull ownership, and now has over 140,000 miles on the clock. I really like these, definite future classic.

For those who have met Nic and seen his previous 240 in person, you'll know that it was way different from all of the other cars out there in the scene today. It wasn't perfect but there was just something totally raw about it that everyone loved. Not to mention the fact that he was extremely low...and static. His new 240 coupe isnt any different. It still had the same raw feel that most cars fail to have. As I sat in the passenger seat, you could feel and hear the scraping of his subframe as we cruised around town looking for a shooting spot. As the car scraped we both would gasp from the harsh metal sound but at the same time couldn't help but to laugh at how crazy it was. It was just a fun car to be in. Nic himself is an awesome kid and I believe everyone should get a chance to meet him. He is on a whole other level and we definitely need more kids like him around the "scene".

For this shoot, I decided to try out something different. Instead of just shooting a car rigged up or parked in front of something cool with blasts of strobes, I wanted to include the driver and his local town to create a "real image" and tell a story. I used only natural lighting to get a "real" feel to it.

This is the current state of an ongoing experiment comparing the use of an uncooled colour planetary camera against a deep sky colour camera. Both have CMOS sensors. The deep sky images are on the same scale as the planetary camera image but I have cropped their area down by about half.

Progress so far suggests that on the right settings the planetary camera can produce a nice close-up of the Ring nebula that with longer total exposure times and the right individual subframe times could be as (or even more) detailed than the wider field views with the cooled deep sky camera.
