I'm in Hemel Hempstead and it's cloudy but I did set up my camera up on my garden table with the tripod fully extended and tied to the parasol so it doesn't fall. I might not get anything but it's wirth a try. The SE coast looks clear around that time. Emil

C/2022 E3 (ZTF) (Take II) This time I captured a few galaxies in the foreground too. Antlia V-Pro Blue 36 mm: 15×120″(30′) Antlia V-Pro Green 36 mm: 15×120″(30′ Antlia V-Pro Luminance 36 mm: 40×120″(1h 20′) Antlia V-Pro Red 36 mm: 14×120″(28′) Total Integration: 2h 48′ Stacked in AstroPixel Processor and processed in Pixinsight, with the help of Noise and Star Xterminator, and Photoshop CC 2023 I used a method somebody shared on facebook and I'm really pleased with it. First in APP I registered all the subs on the comet and saved tham all, after that I registered all the subs on the stars and saved them all. I took the comet registered subs into pixinsight and with the Process batch in StarXterminator, I removed the stars from all of them. This took quite a while but the result was great. When the star removal was finished, I integrated each channel of the starless comet and the each channel of the stars. I did a LRGB combination for the starless comet and a LRGB for the stars and galaxies but because the stars were quite bright in the LRGB, I also did a RGB combination for the stars only. I aligned the LRGB for the stars and galaxies and the RGB for the stars with one of the subs registered on the comet to make sure I have everything in the right position, removed the stars from the LRGB for stars and galaxies to be able to add the galaxies to the starless comet and made a star mask from the RGB stars so I can add it to the LRGB starless comet + galaxies. I tried StarXterminatoon but for some reason the extracted stars looked awful. Starnet did a much better job. Obviously, I had to clone stamp the trailed comet from the starless LRGB for galaxies. At the end I had a LRGB starless comet image, a LRGB starless galaxies image and a RGB image with the stars all aligned and ready to be moved into photoshop. I added the galaxies to the starless comet as a layer in lighten mode and the stars in screen mode. I hope this helps other people too. Emil

Thank you Lee. I do have a version with more stars and no halos too but I prefer this version because it make the nebulosity muck more visible 😊 Emil

Thank you very much, I love it too, made it my desktop and phone wallpaper and I think I will make a large print out of it. I'm so glad I went back to it and re-edited it 😊 Emil

In my case, I was lucky to have the stack in linear state, I tried it on the finished image and because of those huge halos, it looked horrible. I usualy move the stacks, masters and finished image into the folder where I have all the data for that particular target. Emil

Here's a screenshot of the data if you don't believe me

It 21 hours over the course of 2 years but I shot all sort of exposures including 300 and 600sec. You can see the details on astrobin. Emil

Thank you Rodd. I was living in Bushey Hertfordshire when I shot, bortle 6-7. Emil

Since I started my astrophotography journey, I upgraded my equipment quite a few times but the small TS65 quadruplet apo refractor has been a favourite telescope which always amazed me so it always survived the upgrades. 3 years ago, in January 2020, I put together all the data I had on M45, The Pleiades to see what I get out of it. The data was captured using the same TS65Q telescope but 3 different cameras that I had during that period, a modified DSLR, Canon 700D, a QHY10 OSC CCD camera and a ZWO ASI294MC pro CMOS camera. Together with the equipment upgrades, I would like to think that I am also upgrading my knowledge and processing skills and a few days ago I went back over the data to see if I can bring any improvements. The famous BlurX, StarX and NoiseX have been used in the process. In my opinion I did bring an improvement, especially on the stars, what do you think? First photo is the new edit and the second is the one edited in 2020. Technical details on astrobin:https://www.astrobin.com/gakuj5/E/ Emil

Thank you Martin. To be honest, I had it with no glow at the beginning but I thought it looks a bit weird so I went back and left some of it to make it a bit more realistic but at the same time still show the trapezium cluster. As for the saturation, I do indeed tend to add a bit too much in my photos 😁 Emil

For the last clear night of 2022 I thought I should do a target I haven't visited for a very long time, the Orion nebula. I was very curious what I could achieve from a single imaging session. I can do 6 hours start to finish on Orion but the East is not great at low altitudes so I started when the target got to around 25 degrees in altitude and finished when it was at 15 degrees altitude in the West. The west is much better for light pollution so I can go lower with the narrowband filters. Trapezium was processed separately. I never thought the platesolver can solve 4 stars in the trapezium when using the small, modest TS65Q.

Congratulations to the winners! 👏👏🙂 Emil

Thank you very much! Emil

I've seen many versions of this faint target and I really wanted to have a go at it myself. Thank God for Star and Noise Xterminators because without them, I don't think I would've been able to stretch the balloon until it popped 🎈😂 Technical details and full resolution on astrobin https://www.astrobin.com/8ffdu6/C/ Emil

I haven't done a mosaic in quite a while, this is only a 2 pane one to warm up a bit This is my version of SH2-126 and LBN 437 (The Gecko Nebula) in HaLRGB - 2 Pane mosaic SH2-126 is a large emission nebula in the Lacerta (The Lizard) constellation and it apears in this image as the red nebula. The source of its ionisation is the intense ultraviolet radiation from the star 10 Lacertae, a blue main sequence star. The yellow-brownish nebula, which forms a "stellar funnel" in the centre-top of the image and snakes away to the right, is designated LBN 437 also known as The Gecko Nebula. It is a molecular cloud whose densest part is associated with some bright young stars. Its most striking feature is a symmetrical reflection nebula associated with the Herbig Ae/Be star V375 Lacertae. This star is also responsible for the bipolar Herbig-Haro objects within the nebula. Herbig-Haro objects are small nebulae around young stars. They form when gas ejected by the star hits dust clouds. This region, with its faint nebular filaments, is part of Lacerta OB1, a giant star-forming region about 1200 light-years from Earth. The nebula emits its light in broadband and in isolated emission lines.

I did, yes but I didn't want to reduce the number of stars. I do it on the narrowband images but not too much on the broadband ones. And on top of that, cleaning the artefacts left over after the removal is something that I don't find pleasing. Emil

I know some people do hate them, my love for them is probably coming from the HST images that I was crazy about when I was younger. Emil

Thanks Alan, I'm a bit of a sucker for spikes and I tend to add them to some photos that I think would benefit from them. I've never been able to get the results I wanted from any of the newtonians that I had in the past so I am now only using refractors but my love for spikes didn't die. I was actually thinking of fixing some wires in front of the lenses 😂 Emil

Thank you very much Olly, much appreciated, I'm glad you like it 😊 Emil

My first finished target from my new back garden. Happy to be back to DSO imaging after a 6 months break. With the sky being much better than my previous location in Bushey, I went for a broadband target but having the Dengel-Hartl 5 planetary nebula in the frame too, I also shot some Ha and Oiii to make it pop.

Can I still enter if I started the target on the 25th August? It's quite hard to get many hours to finish a target during the 3 months period. Was lucky to get some clear skies at the end of August but a lot of the subs have been shot in September. Emil

Wow, thank you very much, great entries, wasn't expecting it 😀 Congrats to Russ, Pete and everyone else that took part 👏👏 Emil

Cygnus at 135mm Test of my iOptron Skyguider Pro with results that didn't disappoint. I used my astromodified canon 6d and my Samyang 135mm f2 lens and I chose Cygnus as the target. Only 22 x 60sec exposures, ISO1600 @f2.8 Emil
