that's it exactly ! thank you So Elon space junk then

So this was in southern Spain, 17th July 2023, at 21:41 local time, just north of Malaga. It was a bright streak, about as bright as a fireball meteor but moving much more slowly. There was a streak of about 20 brightly lit objects all in the exact same line of travel, falling to earth, but much much slower than any meteor I've ever seen - every object was visibly moving at about satellite speed, and they must all have come from the break-up of a larger object since they were all in the same line. Altogether it must have been in the sky for at least 15 seconds - enough time for me to grab my phone, find the right app, night-time setting and take this (awful) photo. This photo was quite a bit after its maximum brightness. It didn't have the bright 'head' that fireball meteors often do, each object was about equal brightness I'm aware 17th July was the start of the Perseids, but I've never seen a meteor like this. Any ideas ? Is Elon missing a satellite ? Aliens landed in Malaga ?

HOO: HSO: And then I did two with dramatic hue shifts from HSO, trying to get maximum differentiation between the three narrowband channels - quite please with the results Ha->orange/yellow, SII->green/cyan, OIII->violet: Ha->violet, SII->orange, OIII->green: 13 each of 900s Ha, Oiii and Sii, darks, flats and bias. Skywatcher 200PDS newt (200mm ap, 1000mm fl, f/5), Moravian G2-8300 mono CCD +CC, AZ-EQ6GT, QHY5L11C OAG guiding. Pixinsight. Hope you enjoy !

thank you all ☺️

Just a feeble two for me this year, the pandemic has still been eating into my scope time. Hoping for much better this year... heart of the Heart Nebula in SHO Lobster nebula in SHO - needs more data, but I can literally only get 4 frames per night !

A multi-year project for me, and adding on to my very meagre output since the pandemic hit: I've added on 18x900s each of Oiii and Sii to a monochrome Ha image I took 3 years back. 27x600s Ha, darks flats and bias, equipment as per sig, Pixinsight. Hi res image here and original B&W image here Hope you enjoy !

thank you 🙂

Covid put a serious dent in my astrophotography, wow. My equipment is in Spain so this set, taken in the summer, was the first chance I had in about 18 months. Hi-res version here 11x Ha and 8x Oiii and Sii 900s. Darks, flats and bias, equipment as per sig, Pixinsight. This was taken in southern Spain - it's definitely low for me, a bit of a tree skimmer and shooting through the light pollution dome over Malaga (one 'advantage' of Covid was that the normal Feria lights for that time of year weren't on), but I have a bit of time as it passes over the end of the valley. From being dark enough to set up, to losing it in the trees, I was able to get 4 shots per night. Needs more data really, maybe a multi-year effort. NGC 6357 is a diffuse nebula in the constellation Scorpius. It is known as the Lobster Nebula (view this upside down, maybe the two blobs look like eye-stalks ?), the Madokami Nebula (after the Japanese anime Madoka Magica due to its resemblance to the main character, there was a fan petition to rename it), and as the War and Peace Nebula (in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull). The nebula contains many young stars and proto-stars shielded by dark balls of gas. This nebula includes the open cluster Pismis 24 (the small group of stars immediately below the blue in this image), which is home to several massive stars. One of the brightest stars in the cluster, Pismis 24-1, was thought possibly to be the most massive on record, approaching 300 solar masses, until it was discovered to be a multiple system of at least three stars; component stars would still remain near 100 solar masses each, making them among the more massive stars on record. It is located about 5,500 light years away from Earth. Hope you enjoy !

This is SH2-86, which is a faint emission nebula in the constellation Vulpecula, close to the Dumbell Nebula. I took these subs while back, but just got round to finally processing it. I have a full set of Oiii and Sii too, but got hardly any signal from either, so in the end I decided to go moody black & white Ha 17x900s Ha, darks, flats and bias, equipment as per sig, Pixinsight processing I don't normally do starless, except for fun, but thought this one was rather striking: SH2-86 contains open star cluster NGC 6823 which is about 50 light-years across and lies about 6,000 light-years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. Hope you enjoy ! Stuart

yay, I just got another Astrobin top pick !

thanks all ! I've got over 2100 likes on Reddit for it ! Perhaps I should sell shares in it 😉

Seems to have turned into a bit of a multi-year project, this one - the original Ha was taken in 2017, though not nearly enough of it, and the Oiii and Sii in 2018, then I managed, pandemic notwithstanding, to add a lot more Ha to it: Has BBCode broken by the way ? SHO: Click for hi-res and a monochrome 2x drizzled Ha detail: Click for hi-res 9x 600s plus another 13x 900s Ha, 10x each 900s OIII and SII, darks flats and bias, equipment as per sig, taken in southern Spain, PI processing. This thread was my previous attempt,but I'm a lot happier with the colours this time. Hope you enjoy !

For a while I thought I wasn't going to get any at all this year, because my kit is in Spain, but I did manage two weeks in the summer.

decided to give this another go - having got my new monitor, I think the previous version was definitely looking a bit too saturated, so I've tried to bring that down. Also trying to get a bit more of a natural blue shell going round it, and I managed to integrate my RGB star colours better. What do you all think - better now ?

thank you 🙂
