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.

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".

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.

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.

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 ☺️

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).

I was struggling to somehow show the blue colored Squid nebula blanketed inside the red colored Flying Bat nebula
Celestron C8 with Starizona Hyperstar at F/1.9 using Optolong L-eXtreme F2 dual band filter, ZWO ASI294MC Pro camera
6 hours 24 minutes total integration time
192 x 2 minute subframes
The bright blue reflection nebulae of M78 glowing amidst intertwining lanes of dust and gas, with a section of the bright red emission nebula Barnard's Loop in the lower left of frame.
This image is an integration of 20 hours total exposure (241 x 300s subframes) shot on a QHY168C OSC with a WO Zenithstar 103 telescope. An STC astro-multispectra filter was used. Imaging was managed via Sequence Generator Pro and guiding controlled via PHD2. All post-processing was carried out in PixInsight.
Observed from Prachinburi, Thailand.
Messier 45, the closest of any of the 110 Messier objects. It is located in the constellation of Taurus, 444 light years away, visible with the naked eye.
I took this over 7 nights from Sept 15-Dec 12, 2023

I have been trying longer subframes with the Hyperstar, outside of the 30sec I have been stuck on for years. Each panel has a minimum of 20 frames at 120 seconds through an Optolong LUM filter. I'm starting another round hoping to double them by the end of the season

1999 Alfa Romeo 156 1.8 T. Spark.
Scrapped (last MoT test expired in September 2015).
It failed a test that month -
Nearside front subframe mounting prescribed area is excessively corroded (2.4.a.3)
Supplementary restraint system warning lamp indicates a fault (5.4.2)
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."
