This is a stack of 8 150 s exposures taken around 2021-06-11 05:15 UT. The Leo Triplet consists of M65 (lower right), M66 (lower left) and NGC 3628 (top). These galaxies appear in Leo, about 8° north of the ecliptic. Since the inclination of Vesta's orbit is a bit over 7° to the ecliptic and its orbit is larger than Earth's, it can be photographed with the three galaxies.
Subframes taken with an Atik 314L+ color CCD on a HyperStar on a Celestron Edge HD 925. Preprocessing in Nebulosity; processing in PixInsight with final touches in Photoshop.
Vesta is the bright object in the lower right corner.

Description:
The star pattern in the constellation Scorpius (The Scorpion) is one of the most recognizable in the sky. The lower part of this pattern - the tail of the scorpion - lies very low in the sky as seen from the northern hemisphere. From southern latitudes, however, this part of the sky is directly overhead during nighttime hours in the months of April-July.
Our home galaxy, the Milky Way, passes through Scorpius, as can be seen in this view. Numerous pink hydrogen gas clouds and many star clusters are concentrated in this part of the sky as well.
This is the telescope and mount that I used for my astrophotography on this trip:

#Subframing #FlickrFriday
I'd set out to use this WW2 coastal look-out bunker somehow for Flickr Friday anyway, but this as-found can was a gift from the photography Gods :-)
Over the past weekend, Rochester experienced something rare - four clear nights in a row! While it is true that the moon did not make for the best time for astro imaging, I had to take advantage of the rare clears skies and so I had both of my imaging platforms out catching photons every night!
The first image I am ready to share from this series is M81 and M82. I have been wanting to image these two beautiful galaxies for a while now and I finally got my chance!
Messier 81, also known as NGC 3031 and Bode's Galaxy, is a beautiful spiral galaxy located 12 Million light years away in the constellation Ursa Major. It was first discovered by Johann Elert Bode on 31 December 1774, thus the common name of Bode's Galaxy. M81 is the largest galaxy in a group of 34 galaxies, known appropriately enough as the M81 Group.
Messier 82, also known as the NGC 3034 and as the Cigar Galaxy, and is also located 12 million light years away and is part of the M81 group of galaxies. M82 is an extremely luminous galaxy - being five time brighter than our own Milky Way, and has a core that is 100 time brighter! This is due to intense star formation caused by gravitational perturbations from interactions with M81. M82 is known for its complex network of dusty filaments that extend to the side of the galaxy.
This particular image is the result of 191 subframes with an exposure of 180 seconds, for a total integration time of just over 9.5 hours. These frames were taken over three nights.
I would really like to image this again using narrowband and see if I can get a better mage of the tendrils from M82! - A fun future project…..
Details for this image:
191 x 180 seconds, bin 1x1, unity gain @ -15C. (Total integration of 9.55 hours).
50 Bias exposures
34 Dark exposures
45 Flat Darks
30 Flats taken each night, each nights data was calibrated to these flats.

Captured from my backyard in Gérgal, Almeria Spain over 3 nights.
This project was to be paired with RGB stars from the RGB image also posted here. Unfortunately the stars were not good enough due to a rotator tilt problem I had during some of the imaging sessions. Instead, this the whole image with Ha, Sii and Oiii data.
Captured on 21, 22, 23rd of February 2022.
Subframes
59 x Ha 300s : 4h 55min
42 x Sii 300s : 3h 30min
51 x Oiii 300s : 4h 15min
Calibration:
20 Bias and Darks
20 Flats for each filter per night.
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.

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:
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)."

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 ☺️

A mystery hides within 20 of the subframes within this image. I will reveal the oddities as I organize a good way to present them. I'm not saying they are unidentified aerial phenomena or aliens, but they do indicate a mystery object not recorded in satellite catalogues.

M-1, aka NGC 1952.

This is a tiny target, so I used my intrepid C8 since it has a good reach. However, there's nothing like a long focal length telescope (f/10) and a narrowband filter (L-Ultimate) to humble you. I had a hard time polar aligning and framing using NINA because of the narrow FOV and dark filter. NINA complained that there were not enough stars to plate solve. I used long exposures and high gain, but with no success. I removed the filter, refocused, but plate solving would not work.
I switched to SharpCap and it performed better, but had its own idiosyncrasies. I selected dithering while guiding and left the default settings on. When the mount dithered, the target moved from one side of the frame to the other. Siril was unable to align the subframes in post-processing, so I dug out my old copy of Nebulosity 4.0 and did a manual two star alignment that seemed to work. Because of the stacking artifacts, I had to severely crop the image.
The image looks more like a gold nugget than a supernova remnant. Not the best output, but I learned a lot, like use a focal reducer next time.
February 1, 2026, Tallahassee, Florida, Bortle 7, full moon. Seeing was poor and there were thin layers of high altitude cirrus clouds passing by while imaging.
Old "Halley Era" Celestron C8 (1988 more or less) at native f/10, ASI533MC Pro, L-Ultimate narrowband filter, iOptron HAE29; total of 44 120-second light frames with calibration frames. Gain 100, Offset 10. Stacked and processed using Nebulosity 4, Siril, and Photoshop. Astronomy Tools had this remark about this scope and camera combination: "The ideal pixel size for Poor Seeing (4-5" FWHM) seeing is: 1.33 - 2.5" / pixel. This combination leads to slight over-sampling. Will require a good mount and careful guiding."
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.
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.

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.

The Borgward B 611 is a light commercial vehicle built by Borgward at their Bremen factory between 1957 and 1961. Only 14.748 units were made.
The vehicle was offered as a light van, a minibus (with rear seats and more windows) or as a platform wagon (Pritschenwagen), although several other body styles were available either directly from the manufacturer or from specialist body manufacturers.
The van was launched in 1957 with the name Borgward B 1500 F. The suffix "F" stood for "Frontlenker-Transporter", and referred to a design feature that was a first for Borgward, where the driver was positioned right at the front of the vehicle instead of behind a hood with an engine underneath. The engine was installed in a large pod between the driver and his passenger. Where three seats were used in the driver's compartment, the middle passenger sat on top of the engine cabin. According to most sources, it was not until 1959 that the vehicle was given the name by which it is more remembered today, Borgward B 611. Buyers of the B 611 could choose between a 1493 cc petrol engine delivering up to 60 hp (45 kW) and a 1758 cc diesel engine with a maximum power of only 42 hp (31 kW). The petrol unit was shared with the Borgward Isabella which had been introduced a few years earlier. However, the gear ratios were not. The B 611 came with a four-speed fully synchronized manual gear change, operated by a column-mounted lever. Claimed top speed was 92 km/h (58 mph) for a petrol powered van and a more leisurely 75 km/h (47 mph) for buyers selecting the diesel engine.
The B 611 stood on a steel chassis with ladder frame and transverse reinforcement bars. At the front, independent suspension used side-mounted wishbones with coil springs. A rigid swing axle was suspended at the rear with longitudinally mounted leaf springs. The engine, clutch, transmission, radiator and front suspension were all supported by an additional subframe. With a wide comfortable cabin that seats three people and uses uncomplicated technology, the Borgward B 611 won friends in the press and on the market. By the time of Borgward's controversial bankruptcy in 1961, the manufacturer had produced 14.748 of them. (www.metropoleclassiccars.com/)

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.

Description:
Our home galaxy, the Milky Way, runs through the constellation Cygnus (the Swan) in the northern hemisphere summer sky. Dense clouds of stars are obscured in places by winding lanes of dark foreground gas.

Capture Location: Near Goldendale, WA
Processing Software: PixInsight v1.8
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.
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.
Stack of 46 exposures of various lengths (mostly 4 minutes, but some 6 minute and 2 minute subframes as well) shot with an Atik 314L+ color camera on an Edge HD 9.25" at f/2.3 with Hyperstar. Preprocessing in Nebulosity, stacking and processing in PixInsight, final touches in PS CS 5.1.

I recently acquired a Starizona HyperStar for my Celestron C9.25 XLT telescope. The HyperStar replaces the secondary mirror on the SCT. It is a lens system that reduces the C9.25 focal length from 2350mm to 525mm and the focal ratio from f/10 to f/2.2. This effectively converts my narrow-field system into a very fast wide-field imaging setup. Using this accessory I can take high quality images of wide-field objects (comets, nebula, large galaxies) in significantly less time than my wide-field refractors (I have two refractors, an f/7 and an f/4.9).
My plan is to use the HyperStar to image Comets 2025/R2 (SWAN) and 2025/K6 (Lemmon) once they are at a "reasonable" elevation here in the SF Bay Area.
To prepare, I used Andromeda for my first light target to get some practice with the HyperStar. The image above is the result of 45 x 1-minute subs - 45 minutes! This detailed of an image would require 3-4 times the integration time using one of my refractors.
I am looking forward to trying the HyperStar to image one or both of the comets now in our vicinity. I am not making any promises, but I hope to post an image of at least one of the two comets within the next 2-3 weeks.

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.
