We had clear skies for a few hours last week, so I tried grabbing data in 5 channels from my light polluted backyard.
L channel: combination of 25 s and 60 s subframes
R channel: 29 60 s subframes
G channel: not usable
B channel: 41 60 s subframes
H-alpha: 11 180 s subframes
There was a weird artifact in my green channel images, so I mixed the signal from red and blue and used photometric color correction on the resulting RGB image to try to adjust for it.

Description:
On of the brightest patches in the northern section of our home galaxy, the Milky Way, lies in the constellation Aquila (the Eagle), Scutum (the Shield), and Serpens Cauda (the Serpent's Tail). This starcloud contains many open clusters of stars, together with foreground globules of cold dark gas that are the incubators of new star formation.
One of the most prominent star clusters in this area of the sky is M11, the so-called "Wild Duck" cluster, which is a favourite observing target of amateur astronomers with modest telescopes. M11 is almost dead centre in this image. This is a rich open cluster of stars that looks like a duck in flight. See en.wikipedia.org/wiki/Wild_Duck_Cluster for more information about M11.

Description:
This large, pretty and bright open cluster of stars - which happens to lie in our line of sight in front of one of the bright and star-dense arms of our Milky Way galaxy - is a favourite observational target of northern hemisphere astronomers on summer evenings.
From Wikipedia:
"The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck)."

This is a large ionized emission nebula and star forming region more than 100 light-years in diameter, located about 2,400 light-years away in the constellation Cepheus. The gas cloud is energized by the bright multiple star HD206267, which is just a little right of centre in this image, as well as by the entire cluster (Tr37) of young, bright, bluish hot stars that is in the centre of the cloud.
Per Wikipedia: The HD206267 "system is emitting a stellar wind that reaches an exceptional velocity of 3,225 km/s, among the highest measured for stars of this type".
The very small Elephant’s Trunk Nebula (IC 1396A) is the elongated globule to the right of centre. Up to 250 stars are in the process of being created in this nebula. One 2012 study of this region argues that "the TSF [triggered star formation] mechanism in IC 1396A is a radiation-driven implosion process persisting over several million years".

Description:
The familiar "W" shape of the constellation Cassiopeia rises in the north-eastern sky after midnight in mid-summer in the northern hemisphere. The Milky Way galaxy runs through this part of the sky. Many open clusters of stars, loosely bound together gravitationally, also populate this area of the sky.
Many dark tendrils of foreground gas obscure the light of the stars beyond in this view.

My only other image of this galaxy was from when a supernova was visible.
Now? No supernova.The RGB data was taken in October 2020 with Hα data added in January 2021. This image is a bit of a mess, but it was what I could do with about 3 hours of data from my very light polluted yard.
All subframes taken with a Celestron Edge HD 925 at f/2.3 with Hyperstar. RGB data was taken with an Atik 314L+ CCD camera with a light pollution filter; Hα data was taken with an Atik 414-EX with an Atik hydrogen-alpha filter. Preprocessing in Nebulosity; channel combination and subsequent processing in Pixinsight; final touches in Photoshop.
IC 443, commonly known as the Jellyfish Nebula, is a supernova remnant located in the constellation Gemini about 5,000 light-years from Earth. It gets its name due to its peculiar shape, resembling a jellyfish floating in space. IC 443 is the result of a massive star explosion that occurred thousands of years ago leaving behind a cloud of gas and dust that spans approximately 70 light-years across. The bright star on the left is Eta Geminorum aka Propus and is part of a triple star system.

I think this could sum up a lot of emotions right now as our world is stood still but working together for the greatest cause.. it is such a strange and weird time - it’s almost like your body has been granted the rest it’s been craving, you’ve been unplugged from the mains and the subframe you were running and given a chance for repairs - and that is truly how I felt at the beginning of this lockdown.
This week would be a month for me in lockdown and it’s been so surreal, it’s been a weird mix of trying to understand what I am meant to do with my life now... enjoying the rest but worrying and overthinking about everything that’s not happening or not going to happen and one point at the beginning just feeling like shutting down.
However I have such a wonderful support network and I’ve been to be more in control now I’ve got used to the idea of having to stay indoors. And like me I know that each of you reading this are going through your own process - but that’s okay! You don’t need to be at someone else’s stage in this process - live each day to your fullest - do what you feel you can and want to do! There is no right or wrong in this!
One thing I do have to say though is that this is a weird feeling knowing that the next series of images that will be coming out by me are all of me! I don’t do self portraits a lot but this I see as creative challenge ☺️ and this is the first image I got to edit using Adobe lightroom! I’m certainly starting to branch out my creativity and I can’t wait to see how it goes 🙌
Let me know what you think and what you’re doing to stay sane ☺️
Most astrophotographers would label this as the Rho Ophiuchi dust complex. I don't think I took long enough exposures to pull out the colors and richness around Antares. I think I need more time with each subframe. This is a stack of 13 3 minute exposures with an unmodified Nikon D80 piggybacked on my Edge HD on a Celestron CGEM mount.

Ferrari AF Corse Hypercar
449P
The car's 2,992 cc (182.6 cu in) twin-turbocharged V6 engine architecture is shared with the Ferrari 296 and its Group GT3 counterpart, the 296 GT3. However, instead of being mounted to the subframe as in the road-going vehicle, the engine is a fully stressed member in the 499P, and has had various modifications to accommodate its new role as a stress-bearing member. The 499P has semi-permanent all-wheel drive, with an electric motor situated at the front axle, providing 200 kW (272 PS; 268 hp) above 190 km/h (118 mph) (as stipulated by the regulations), and is connected to a bespoke 900 V battery pack, with the ability to be recharged by Ferrari's own Energy Recovery System (ERS)
Comet C2016 R2 from this morning. At first, the situation was quite frustrating. The clouds that ran through again and again left only small gaps in order to design and focus the image at all. Eventually the whole sky closed up (I used these shots as flats; -). I just kept the recordings running. And eventually, when I was sleeping, the sky finally opened up. Only the rechargeable battery of the Sony A7s had "given up"until then, so that only 6 subframes were possible in a good sky. What a joy this morning that some subframes were usable between 1:30 and 3:30h.

Description:
M13 globular star cluster: One of the showpieces of the northern hemisphere spring sky is this bright globular star cluster, the sixth brightest in the sky, which is faintly visible to the unaided eye in a dark sky.
M13, which contains about 300,000 stars, was discovered by Edmond Halley in 1714, and catalogued by Charles Messier in June 1764. It is about 145 light years across and lies 25,000 light years from our solar system.
Globular star clusters are ancient objects, originating very early in the history of the universe. M13 is estimated to be 11.7 billion years old.
NGC 6207 galaxy: This spiral galaxy is near the top edge of the frame, a little left of centre. It is located about 30 million light years from our own Milky Way galaxy, and was discovered by William Herschel in May 1787. It shines with an apparent magnitude of 11.7 - 12.2 and is ~34,000 light years in diameter (compared with the Milky Way's diameter of ~100,000 light years).

This huge galaxy--200,000 light years across--that's twice the size of the Milky Way, is approximately 130 million light years away in the direction of the constellation Aries. It is referred to by some authors as “The Nautilus Galaxy.” Its unusual shape is caused by gravitational distortion due by the much smaller NGC 770 galaxy immediately above and to the right. There are an astounding number of other galaxies in this image as well. It is probably the most distant object I've ever tried to image.
Captured at the General Nathan Twinning Observatory in Belen, New Mexico on October 25th and 29th using a C11 HD with f/7 focal reducer, an ASI1600mm camera, ASI L, 7 nm R, G and B filters and a Losmandy G11 mount. 24 x 300” luminance subframes and 12 x 300” each or R, G and B were combined using PixInsight and further processed in PS CS2.
A shock find on streetview. While prepping for a spotting trip, I thought I'd have a look in a random newbuild estate, just because the streetview had been done pretty recently. To my surprise, this pre-facelift Ulysse was sitting, so I went to go and see it the next day.
Long term ownership and off the road since last year, after failing it's MOT on the dreaded Front Subframe. I'd say it's the end of the road for this rare MPV, but kudos to the owners for keeping it about.

"Chassis number: SAXXBANB1BD832552. This 998cc Austin Metro MkI has been off-road for a few years, with its last MoT expiring in December 2018, and a subsequent test in October 2020 producing a fail. The current mileage indicated by the odometer is 64,965 miles and the vehicle was registered in May 1983. The vehicle becomes tax and MoT exempt from April 1, 2024 although work will be required to return the Metro to a roadworthy state; however, it does start and drive well, according to the vendor, who believes the mileage to be correct as he has owned the car for nine years. A new battery has been fitted, while new tyres were fitted four years ago. Three keepers overall are recorded on the V5C.
"Documentation with the Metro includes the V5C, a photo of the car at Sandringham during Drive It Day 2016, various old tax discs and a brochure. There's also a Heritage Certificate, while the MoT certificates date from 2012, 2013, 2014, 2015, 2016 and 2017."

A B2 variable star lies at the heart of this dusty region of our galaxy. The star is not hot enough to produce the UV light needed to ionize hydrogen and give this nebula a reddish/pinkish glow. Instead, shorter wavelengths get strongly scattered by the dust, giving it the classic blue hues of a reflection nebula. The Iris Nebula lies in the constellation Cepheus, which is most easily seen in summer and early autumn from the Northern Hemisphere. It doesn't reveal much when observed visually through a telescope, but it sure does photograph well.

Special:
- Lancia is an Italian automobile manufacturer founded in 1906 by Vincenzo Lancia and which became part of the Fiat Group in 1969. The company has a long history of producing distinctive cars, many technical improvements and also has a strong rally heritage. Lancia quickly earned a reputation for being one of the most innovative carmakers in the world.
- The Lancia Fulvia Series (named after Via Fulvia, the Roman road leading from Tortona to Torino and according to other sources named after Fulvia Flacca Bambula, an aristocratic Roman woman and wife of Mark Antony) was designed in-house (Centro Stile Lancia) at Lancia in Milan - Italy. The technical concept is by Antonio Fessia, the model was designed by Pietro Castagnero. The V-4 engine was designed by Zaccone Mina and mounted forward at a 45-degree angle.
- It was introduced at the 1963 Geneva Motor Show.
- Parallel to the 1C Series ran 2C 1a Series (1964-1967: 48,266 units built) with the same engine but with twin Solex C32 PHH + Solex C32 PHH1 carburettors, 71bhp/6.000 rpm, 92Nm/4.300rpm and a top speed of 145km/h.
- In 1969, Fiat took over production of Lancia, so the Fulvia Berlina Series (1963-1972: 188,637 units built, while other sources say 192,097 units built) was arguably the last true Lancia, all assembled at the new Lancia plant in Chivasso - Italy.
This extends the map of the previous image of Sadr pictured below. Sadr now is the bright star near the bottom. The hazy nebula at the top is the butterfly.
This image is made from 842 separate images called subframes. Each subframe is ten seconds long. Seestar started taking the pictures at 10:54 PM and ended the next morning at 3:48 AM. The total amount of exposure time was 2 hours and about 20 minutes, but because of processing time and dropped frames it took nearly five hours. It took Siril the software used in assembling the images about 2 hours and 12 minutes to put all the individual overlapping images in place.

Special:
- The Lancia Fulvia Series (named after Fulvia Flacca Bambula, an aristocratic Roman woman and wife of Mark Antony) was designed in-house at Lancia in Milan - Italy. The technical concept is by Antonio Fessia, the model was designed by Pietro Castagnero.
- The narrow-angle (13 degrees) V-4 engine was designed by Zaccone Mina and has only a single cylinder head.
- From 1970 until 1973 there was this Fastback Coupé called Sport 1.3 S Series II, designed by Ercole Spada and assembled at Zagato Milano s.r.l., Rho, Italy. The first 600 units of Series II were still fitted with Series I bodyshells (1967-1970: 1,602 units built) with a separate spare wheel-hatch and smaller rear lights and aluminium bonnet and doors.
Comet 2017 E4 (Lovejoy) had a short "lifetime" after its discovery less than 7 weeks ago through Terry Lovejoy. Now the nucleus is desintegrated. To remember its beauty I reprocessed carefully some of the subframes of its highlight day: 2017-04-04 6:04h-6:15h UT. 18 subframes 30 sec each. Hyperstar 14" F1.9. Sony A7s (CentralDS cooled). Tenerife 1180 m altitude. FOV (diag.) 2.9°

Description:
These are without a doubt two of the most popular targets for amateur astronomers with modest telescopes. Unfortunately for northern hemisphere observers, they are located far south in the constellation Sagittarius, so they are very low in the sky, especially for us in Canada.
M20, the Trifid Nebula (left of centre) is a combination blue reflection nebula and red emission nebula. For more information, click here:
en.wikipedia.org/wiki/Trifid_Nebula
The much larger M8, the Lagoon Nebula, is a huge interstellar cloud that is faintly visible to the unaided eye, but only long exposures with the camera can reveal the characteristic red glow of ionized hydrogen gas. For more information, click here:

This incredibly detailed image of the interacting triplet M81, M82, and NGC 3077 was created from more than 216 hours of exposure across three continents — Europe, USA, and Oceania. We combined 4019 subframes and 12993 minutes of exposure to reveal faint details previously masked by lower amounts of data. The high exposure time also allowed us to sharpen fine features, giving the image more contrast and revealing more fine structures.
On the top of the image lies NGC 3077, a small starburst dwarf galaxy with a starforming core. Below lies M81, a grand design spiral about 12 million light years away. To the right is M82, a starburst galaxy with a huge superwind triggered by interaction with M81 and NGC 3077. All around the image is the galactic cirrus, dust lit by the glow of the milky way. I highly recommend looking at the image with HI emission overlaid, which displays what of the background is neutral gas from the interactions and what is dust from the milky way.

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.
Shot from Mt. Pinos, CA on the morning of 2016-07-08. The Cocoon Nebula is an emission nebula in Cygnus. There is a long tail of dark nebulae extending away from it to the west (to the right in this image).
This image is a mosaic of three separate regions. Each panel of the mosaic is a stack of 150s subframes taken with an Edge HD 9.25" at f/2.3 with Hyperstar, and an Atik 314L+ color CCD. Preprocessing done in Nebulosity; stacking, compositing, and processing in PixInsight; some final touches in PS CS 5.1.

Description:
This large, pretty and bright open cluster of stars, at the lower right in this view, happens to lie in our line of sight in front of one of the brighter, star-dense arms of our Milky Way galaxy. It is a favourite observational target of northern hemisphere astronomers on summer evenings. More than 30,000 stars can be seen in this photo.
From Wikipedia:
"The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck)."

Description: I developed this image of the North American Nebula NGC 700 from 60x300s subs or 5.0 hours of total exposure time. I used the Optolong L-eXtreme Dual Bandpass Light Pollution Filter. It has two 7nm pass bands centered on the H-alpha and OIII wavelengths. With a one-shot color (OSC) camera and an L-eXtreme filter combination the red signal from the H-alpha tends to dominate. In the nonlinear postprocessing phase I applied Histogram Transformation, Local Histogram Equalization and Curves Transformation in small doses in multiple passes.
Date / Location: 20, 25, 26 June 2022 / Washington D.C.
Equipment:
Scope: WO Zenith Star 81mm f/6.9 with WO 6AIII Flattener/Focal Reducer x0.8
OSC Camera: ZWO ASI 2600 MC Pro at 100 Gain and 50 Offset
Mount: iOptron GEM28-EC
Guide Scope: ZWO ASI 30mm f/4
Guide Camera: ZWO ASI 120mm mini
Light Pollution Filter: Optolong L-eXtreme Dual Bandpass
Processing Software: Pixinsight
Processing Steps:
Preprocessing: I preprocessed 60x300s subs (= 5.0 hours) in Pixinsight to get an integrated image using the following process steps: Image Calibration > Cosmetic Correction > Subframe Selector > Debayer > Select Reference Star and Star Align > Image Integration.
Linear Postprocessing: Dynamic Crop > Dynamic Background Extractor (both subtraction to remove light pollution gradients and division for flat field corrections) > Background Neutralization > Color Calibration.
Nonlinear Postprocessing and additional steps: Histogram Transformation > Noise Xterminator > Histogram Transformation (small doses in multiple passes) > Local Histogram Equalization > Curves Transformation (small doses in multiple passes).
