Petite photo, faite depuis la maison dimanche dernier, d’une petite partie des dentelles du cygne, qui comme son nom l’indique est dans la constellation du cygne
Elles sont situées à 1500 années-lumière de notre terre
Il s’agit de ce qu’on appelle un rémanent de supernova
Il y a 45000 ans, nos ancêtres ont très certainement aperçu dans le ciel un point très brillant, visible peut-être même en plein jour, comme ce fut le cas en 1054 pour un phénomène identique, ce point très lumineux a été visible sûrement plusieurs semaines, une étoile en fin de vie venait d’exploser, la matière projetée lors de l’explosion va se répandre dans l’espace, et c’est ce que nous pouvons distinguer sur cette photo
Pour ce qui est de la photo, il s’agit d’un travail d’équipe

This is my first composite LRGB deepsky image. I do not have the right equipment to make this kind of photography (for example, I have no guide), but nevertheless last summer I decided to take a shot with a famous and bright object.
So, here it is: the Dumbbell Nebula, a planetary nebula in the constellation Vulpecula! Each channel is made of 20 stacked frames, taken with an exp. time of 15 sec. and gain 300.

ZWO ASI120MC camera, Celestron C8 8" SCT telescope, Celestron CGEM mount. 54 frames per second captured in SharpCap, 1500 frames stacked in AutoStakkert.
I did another drive out to a dark sky location on the night of the 12th/13th. This time near Thirsk in the North York Moors. The location was ok although a lot of trees.
The night consisted of general visual observing with telescope and an attempt to get to grips with Jupiter. I tried to find Ison really early in the morning but didn't get it. My patience in 0c was wearing thin and I think the frost had set in on my equipment making life difficult.
This was my first attempt with a webcam which has been kindly passed down from Tommy Wakey at the Salford Astronomical Society who has now moved on to use a specialist CCD camera. Getting to grips with this was difficult having to improvise getting it into the telescope with the metal bit of one of the eyepieces and some ducktape. It would be useful to know how to turn off the light.

Although its unbranded the webcam looks like a Phillips Toucan.
Used Sharpcap 2 to video the planet taking around 1000 frames.

I'll have another go at some point with the x3 barlow. Focusing on the x2 was hard enough so may not get much of an improvement.
On the eastern border of the Mare Imbrium are the great Plato crater (101 km in diameter) and the Monter Alpes, a mountain range 250 km long and 50 km wide, interrupted by the Vallis Alpes, a fracture valley flooded with lava at the time, which extends for more than 150 km in length. Further to the right we find, in full sunset, the two craters Aristoteles (88 km) and Eudoxus (68 km).

This photo has had the saturation increased to emphasize the different minerals on the lunar surface (blue=titanium rich, brown=iron rich). Surprisingly these colors are visible to the human eye, but *way* less saturated than in this photo (I can usually make out the color difference between Mare Serenitatis and Mare Tranquillitatis when looking through my 5" maksutov telescope) Captured at 6:30pm on February 21st, 2021.

from Wikipedia
The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.
The Crescent Nebula is a rather small object located about 2 degrees Southwest of Sadr. While considered bright by astronomical imaging standards, visually it is relatively faint. For most telescopes it requires a UHC or OIII filter to see. Under favorable circumstances a telescope as small as 8 cm (with filter) can see its nebulosity. Larger telescopes (20 cm or more) reveal the crescent or a Euro sign shape which makes some call it the "Euro sign nebula".

Mars reached opposition on 13th October and doesn't come this close to Earth again for another 15 years. To mark the occasion we decided to attempt making a video of its rotation. The 10th of October was the clearest night close to opposition. We started later than we originally hoped because we needed to test the collimation of the telescope after a recent cleaning of the mirrors, but we worked until quite late and only stopped when Mars set behind houses so we managed to get 22 frames of video. The video shows the rotation of Mars over a period of two and a half hours from 01:23 to 03:53. Each shot an average exposure of 3.53 seconds (2000 frame videos with only those of quality of 75% and above used). A five-minute pause was left between each video. The playback is at 15fps.

The image was obtained using SharpCap LiveStack: 104 X
8 s exposures, and was stretched during stacking by the software
interface. The OTA was a 6" Cestron NexStar 6SE SCT with a
GOTO alt-az mount for tracking. The camera was a ZWO 224MC
color astro-cam with attached Apertura 0.5X focal reducer lens and
a ZWO IRCUT1 IR cutoff filter.
It was post-processed using GIMP and Topaz DeNoise AI, primarily
to increase contrast and adjust the blackpoint background.

Partial Solar Eclipse - June 10th 2021 - 10am-12pm approx. From my East facing Window in Peckham, London.
I am sharing this image more as a reminder suvenir to myself as its not a very good capture because I wasn't focussed on imaging but on a spontaneous streaming with a couple of great companions from my Flamsteed Astronomy Society,
As I continue to restrict my astro viewing within my home indoors at my window sill, I could thankfully witness this rare and my very first Solar Partial Eclipse. But it was a challenge for all in London as it was a story of cloud eclipse totality! But despite 100% cloud, there are moments of thinner cloud that enables th eclipse to punch through but it also meant I needed to keep adjusting the exposure levels constantly to see the eclipse.
Just before the start of the eclipse, I spontaneously thought to invite on Zoom, a couple of my committee friends, Andy and Simon from Flamsteed Astronomy society, who were just chilling out in their gardens, trying to view the eclipse themselves through the cloud. They watched my streaming the clouded eclipse on Zoom (doubling up as a test of how effective streaming solar is from my setup and if the sunspots show up on their screens for possible future society wide event solar observing streaming events).
Because of their companionship and their nonstop jokey personas, it was a really enjoyable hour making this memorable and I thank them very much for sharing this event with me.

Object Details: The attached shows Jupiter as it appeared in the early morning hours of July 27, 2021. With south being up in the attached composite; a variety of different types of features are discernable.
Several large 'white ovals' are visible at upper left and upper right in the southern temperate and southern polar regions - most prominent in the luminance shot. A large 'blue festoon' is visible along the southern edge of the Northern Equatorial Belt, showing quite prominently as the very dark, rectangular-shaped feature near center in the infrared image. Two dark 'brown barges' can be seen just below center in the luminance image on the northern edge of the Northern Equatorial Belt, with another partially visible at approximately the same latitude just on the left limb of the planet. Another rather large storm is visible on the edge of the Northern Polar Region, seen in all three wavelengths, it is prominent as the bright spot at lower right in the Methane image.
In addition to the features visible in Jupiter's atmosphere, during this imaging session the Jovian moon Europa reappeared from behind the planet, followed later by the reappearance of Io as shown in the methane image. Although I have not yet processed the images, I was able to catch Jupiter again this week. Having passed opposition last week, and thinking I may have caught it at nearly the same longitude as the attached shots, I will look forward to seeing what, if any, changes are detectable given the month of elapsed time between the two imaging sessions.
Image Details: Taken by Jay Edwards on July 27, 2021 at the HomCav Observatory using a 3X Televue barlow with set of specialized planetary filters on a vintage 1970, 8-inch, f/7 Criterion newtonian reflector with an ASI290MC' planetary camera / autoguider'. Like other planetary images posted previously, the scope was mounted on and tracked with a Losmandy G-11 running a Gemini 2 control system.
As presented here, the individual shots have been resized down to 50% of their original size and processed using a combination of Registax & Paint Shop Pro.
With Jupiter reaching only 35 degrees above our southern horizon, and this particular evening being bathed in wildfire smoke, I was pleasantly surprised at the results.

While taking photos of the lunar eclipse, never did I think I would actually capture a meteor striking the surface of the moon!
You can see the quick flash of light in the lower left quadrant of the moon, which happened at 10:41 PM CST.
This was definitely luck and that night I just decided to set Sharpcap to capture exposures every few seconds during the hour leading up to peak totality (hoping to get an airplane in transit).

Seeing as I can't get any imaging done at the moment, I'm scouring my computer for data that haven't been processed yet - and fortunately, there are some. On 1st March we imaged Venus but because it was about to set behind houses and it wasn't even dark enough to see Polaris, we only did the most basic of polar alignments. That's not really a problem for imaging planets, however, once Venus had set we slewed the scope over to the Moon and continued imaging with the hope of making up a mosaic of the waxing crescent Moon before that too followed Venus behind the rooftops. Alas, there was so much movement in the shots that most of the ones I processed looked awful so I just stored the rest on my hard drive and promptly forgot about them...until now. Amongst all those video files are a few shots that don't look too bad and this is one of the best so far. Just as an experiment I thought I'd boost the saturation to show the mineral composition of the Moon. I've done this before on full Moon shots but I haven't tried it on a close-up and I rather like the result. The large impact crater just left of centre is Crater Theophilus. I measured its diameter to be 103.53 km (not far off the 100 km diameter given by Wikipedia - which also tells us that it has a depth of 4200 metres). Crater Theophilus partially intrudes into the comparably sized crater Cyrillus to the southwest. In the centre of the image is the much smaller crater Mädler situated in the middle of Mare Nectaris. All of these features are located in the central-eastern part of the near side of the Moon a little south of its equator (south of the site of the Apollo 11 landing in Mare Tranquillitatis).

Colors turned out shit when I tried combining the other filters into an RGB image, so I decided to just process the monochrome image through my red filter. Using a red filter helps sharpen the view, as red light is scattered by the atmosphere less than green or blue light. Captured at 6:30pm on February 17th, 2021.

It was very cold (11 Degrees F) This is the first real chance I've had to use the Ha modified Nikon 610. It went fairly well. I had issues with tracking towards the end of the session. I assume that was related to the cold. Everything frosted over during the session, but dew heaters kept it off of the lenses.
