  1. This is an HOO two panel mosaic of Sh2-132, or the Lion nebula. I managed to grab 5 hours of each filter on both panels, unfortunately I still need more data on my SII filter. Ideally I want another few hours on the Ha and OIII too, but the weather looks very unpromising next week. This is my first mosaic, and despite making a few errors, and Pixinsight refusing to solve the images, I got there in the end by using the Star Alignment/GradientMergeMosaic method. just wish I could have got the framing a little better too. Finally managed to grab some SII data to add to the mix. The first image is a straight up SHO, the second image is an SHO/dynamic SHO mix.

  2. This is a SHO of Melotte 15. The combination was a mix of straight up SHO and dynamic SHO at a 40/60 ratio. 10 hours each of SHO filters at gain 139, offset 21 with my ZWO 1600 MM. Processed in Pixinsight, with a final tweak in Photoshop. Cropped to focus on Melotte 15 and the dark structures in the Heart nebula.

  3. After over 6 weeks without a break I finally got some clear sky. Also no moon so decided to try my very first Dark nebula. The weather did not really co-operate and between passing clouds, me forgetting what to do and some technical issues because of a new imaging PC this ended up at only 3.5 hours. I think it would need at least double that to start bringing structure to the nebula. But at least its a start and some of the nebula is showing. Not sure why the brightest stars are bloated? SW Evostar 80ED, ASI2600mc, NEQ6, Optolong L-Pro, 70 x 180s C & C appreciated.

  5. This is still WIP as I need more, better, data. the subs I have up till now have been plagued with passing high cloud and early shutdowns triggered by the weather monitor. Nevertheless, here it is, 7 hours H-alpha and 6 hours [OIII] in 900 sec subs with the ODK rig. Stacked in DSS and brutalised in AstroArt 8. The H-alpha data had full calibration, but the [OIII] only Darks since 1) I stuffed up getting sky flats for [OII] and [SII] and, 2) adding Bias stuffed up the stack. Note the file says "Third HOO" which might give an idea of the thrashing around I was doing. Still some uncorrected gradients to get rid of. Program of further work, collect more, better [OIII] to replace some of the dodgy data, collect new, correct calibration frames.

  6. I decided to create an animation of the images that I collected during the mostly good seeing of 15 Sept 2021. The animation lasts about 5 secs, but covers an elapsed time of approx 1 hour of Jupiter's rotation, with the GRS in transit. Some variation in the seeing is apparant. To create the animation I produced 36 separate RGB images from the separate R-G-B videos captured with my mono ASI290MM camera through the C14. Thanks for looking.

  7. A 9 panel mosaic of the Cocoon Nebula area. This image was begun during 3 nights in June 2021. Then the rest of the data was added during 3 nights in August 2021 from my driveway 'observatory.' Astropixel processor was used to do the stacks. After a variety of attempts, I finally had to stack the individual sessions of each scope, combine the June sessions images, combine the August sessions images, then combine those masters in the final scope master. Subsequent to that the Tak master and the Sharpstar master were combined. The final image was well over 1.5 gig file size and was 10188x10157 pixels. The crop removed stacking artifacts and the misaligned camera angles. The stacking process took a good amount of time over 4 days. This cropped image is 8216x4246 pixels. The image appeals to me because of the star colors and the impression that the nebula has carved its way through the stars and left a trail. That is probably not a scientific explanation but I guess imagination is a great thing!

  8. Afternoon All, Spent the last few clear nights on this target which I've been meaning to do for a while but hadn't gotten around to. I don't usually do RGB stars with my NB targets but I think it's something I'm going to try and do more often, 28x600s Ha 68x600s Oiii RBG stars, 16x60s per channel. Edited in PI and Photoshop.

  9. HaRGB image of IC59 and IC63, or also known as the Ghost of Cassiopeia. This is a tricky object to process and I'm not 100% happy with the result, need to work more on the blue reflection. Integration: RGB 5 hours of each filter. 2 min exposures at gain 75. Ha 10 hours at 5 min exposures. Gain 139.

  10. I managed 7 hours last night but my iffy framing and clear but blustery conditions meant IC1848 has been tricky. I need some more frames (2x) to get the noise down. For some reason the ASIAIR pro forgot my guide camera settings and set captures to 0.5 seconds -that was a bit chuggy on the graph😀. To mix it up a bit I used a gain of 139 with subs of 300s, 2hrs for Ha and Oiii and three hours for Sii. It has certainly reduced the integration time. Paul

  11. Evening, had a run of clear nights over past week or so which has allowed me to have captured a reasonably deep narrowband image of the core of the Heart Nebula, IC1805, the star cluster that creates the radiation to excite the gasses in the Heart nebula is called Melotte 15 and its a very interesting target. This is a departure from my usual wide and ultra wide field images - I am using my AT106EDT without any focal reducer so its at native 690mm focal length when put together with my ASI1600MM - Pro gives a pixel scale 1.117 arcsec/pixel , which is challenging as I am usually guiding at about 0.7 - 0.9rms - but stars are reasonably round (corners are however a bit egg'y) Colour palette is a a 40/60 combination of SHO, Hubble and coldest nights HOO mix. Processed mostly with Pixinsight and finishing in PS. (i cant ever get the background level right in PI, always have to go into PS to do final curve adjust... Anyway if you have dipped int the Anyone Imaging tonght you will see I have had issues with RPi crashes, voltage drops on mount due to new dew straps and controller and I managed to push my Skyshed dome off its rails trying to keep target in view as it appraoched zenith.....seems to be a habit this past month - perhaps time to build something like a zenith table, but smaller ... Anyway here are the main details for this iamge AT106EDT ASI1600MM-Pro Antlia Ha 3nm Pro 1.25": 76x300" (6h 20') (gain: 200.00) Antlia OIII 3nm Pro 1.25": 60x300" (5h) (gain: 200.00) Antlia SII 3nm Pro 1.25": 60x300" (5h) (gain: 200.00) Integration: 16h 20' Avg.

  12. Stephan's Quintet and the Deer Lick group, NGC 7331 plus "fleas". This is the fourth LRGB iteration that I thought good enough to save, I've thrashed around many more that were total rubbish. 15 subs RGB in G2v calibration (R&G 600 sec, B 1050 sec) and 36 600 secc Luminance subs from the ODK rig. Best 90% stacked in DSS with full calibration, then tortured in AstroArt 8. Saved as a JPEG. If anyone has any ideas as how to proceed from here I'd be happy to know.

  13. Hi all, I managed to get an additional two nights on the crescent nebula though with ducking and diving clouds it's still only 5.5 hours. There's definitely some more Oiii than my first post so overall quite pleased. Stacked in APP and processed entirely in pixinsight. I used the game script ( multi point mask) to draw a really accurate mask around the nebula then inverted for background and re inverted for the nebula which seems a really good tool and then did all the usual workflow. Anyway probably calling this one finished but keeping the subs to maybe add to it next year. Cheers Paul

  14. IC1396 contains the Elephant Trunk and SH2-129 is called The Flying Bat. The latter also contains the Giant Squid (Ou4) but that needs more data to show here. Captured with my triple imaging turret rig with Astrodon 3nm NB filters and Asahi Pentax Super Takumar 105mm f2.8 lenses. Ha - ASI 294MM Pro camera with gain setting of 125. 33 x 300s exposures. OIII - ASI 1600MM-C camera with gain of 60. Lens aperture reduced to f4 to improve stars. 31 x 300s exposures. SII - ASI 1600MM-C camera with gain of 139 (unity gain). 36 x 300s exposures. Capture system used Raspberry Pi Single Board Computers, one on each camera. RPi 4B on the ASI 294 with Astroberry Server and RPi 3B on the others. Capture software was Kstars/Ekos on Linux Mint tower computer indoors and INDI drivers and server in the RPi boards. Image processed in PixInsight, with calibration, star alignment and stacking (Image Integration) followed by Dynamic Crop, Automatic Background Extraction (removes background slope), Histogram Transformation (stretching) and finally Colour Combination of HSO > RGB. Further tweaked with Histogram Transformation.

  16. This is the result of about 13hrs integration, subs were 120s @ gain 200. I feel there is more detail to extract but not sure how best to do it without adding too much noise. In the end I settled for HDR and mild deconvolution in the final stages. NGC7000 was one of the first wide field targets I ever attempted to image way back in 2005 with a modded Toucam + SLR lens, my gear has improved just a bit:

  17. Hi all, first clear night in around a month so nice to be out again. I was going to finish the east veil nebula but didn't fancy my chances of getting much OIII with the moonlight. So opted to have a go at the crescent nebula and at least make a start. This is just 2.5 hours of 5 min subs ( with a stock dslr) so a bit noisy still but I think with another couple of nights on it might turn out okay. Stacked in APP and processed entirely in pixinsight which I'm loving . Definitely will finish the east veil and this before I move onto something else so that's the next two or three clear nights sorted ! CS Paul

  23. Friday was clear, but the moon was bright. So I stripped down the rig and setup to try planets. I used sharpcap and made a few colour depth mistakes - all the first runs were 8 bit. Fixed that and gradually messed with settings to get some detail showing. Gradually increased magnification so in the end I was using a 3xBarlow giving a focal length of around 2700mm. Processing was a bit stab in the dark... never been quite sure how wavelets work! Final result is a bit meh... but there's some detail. I wanted to do Saturn afterwards, but clouds happened.

  24. Clouds took away a few subs last night, so this is the integration of just under 6 hours. The result is not bad considering. (Subs were 120s @ Gain 200). When it comes to processing I'm adjusting the channels by eye rather than just hitting SCNR - it gets me richer colours but less consistent image to image. If the moon is up the next clear night I'll may go back and grab some more to reduce the noise. (I'm waiting for the moon to get out of the way for some broadband targets). Cheers, Paul

  25. First time capturing (part of) the Cygnus Wall...amazing to see the vast fields of gas and dust. Stunningly...and scarily beautiful. Despite bits of cloud drifting over I managed 72 minutes (120sec subs) and used an L-Enhance filter which cut down the moon's brightness. Definitely on my list for acquiring more data.

  29. I never had much luck with M31 before but now I have learnt a bit more patience I'm starting to get results I like. This is the result of 3hrs and 50 minutes of 5min subs @ ISO800 using my resurrected Canon 550d, Optolong L-pro, Altair 70mm EDT-F on my HEQ5pro. I'm pretty happy with picking up the star bridge between M31 and M110, I noticed that disturbance even carries on past M110 if I over-stretch it. More integration time would smooth out the outer regions but I may leave it there to focus on M33 which I have never imaged before. (I really need to get a monitor calibrator - it looks a lot darker in this rendering than on my main screen) Its been a few months since I processed an RGB image here is how it went with one-too-many applications of DBE:🤢

  30. An unexpected clear night yielded some data on the Elephant's trunk. It was a bit of an odd night. Gear all worked brilliantly, but by 10:30 I was so tired I could barely see. So I called it a day a 30 x 300 second exposures. I think 10 or so more might have been useful. I'm going to say this is probably going to be reprosessed. I don't think I did a good enough clean up after starnet++. I am really keen to try the RC Astro pluggin as it seems to go a good job and means I can keep all the post stack processing in Photoshop. This was the first time I've imaged this one.

  32. Monday night was quite misty but I couldn't resist the opportunity to image IC 1396. Through a series of mistakes the outcome wasn't the Elephant's Trunk Nebula, but a nearby region further to the NE, still in the same region of nebulosity but closer to LBN456. Anyway here's the result of 60*180 sec subs with an ASI 1600MC (osc) fitted with a quad-band filter. Not what I intended but quite interesting. Thanks for looking, Roy

  33. Although conditions were very very windy last night, I managed to grab another 3 hours worth of lights. Only lost 4 frames from the whole session so not too bad on the whole. Added to the night before's session gives us just shy of 5 hours of data on this, which is the most I have ever had on any target. Tried to process the same as last time, light pollution cleanup and basic stretch through through APP, fine tuning, colour, star control and noise reduction through Photoshop.

  39. I tried a LUM mask but must have mucked up the steps as the outcome was not good. I'm still hoping to get this right but in the meantime here is a V2. I changed the sequence of processing, basically did a custom deconv on each channel before combining, combined and then noise reduction. This reduced the impact of the stars dramatically (the golden halo around each has gone and they stay sharp) and increased the overall sharpness. After that my same steps. I still hope to get more sharpness and contrast so I will keep at the LUM mask.

  40. After cleaning and correctly(!) fitting my LRGB filters I decided to go a for a bright broadband target. Clouds, moon and poor seeing did not help but I managed about 45 mins each for RGB and Ha - shot with the ASI1600mm. This is tight cropped as I combined Ha from two sessions and the framing wasn't very well repeated. (I really must work out a way to index my camera rotation.)

  41. I got a couple of hours on the Heart Nebula before a huge fog bank rolled in off the sea. It's not great... but I used RC Astro StarXterminator. So far really impressed. It deals with big stars with halos very well. I a few to clean up, but nothing like the quantity I'm used to from Starnet++. Threre was a fair bit of "Snow" (the fuzzy faint stars that are sort of half there, half not) after I pused the curves (probably too hard). It does do a really good job - zooming in I couldn't see any checkerboarding I've seen on Starnet. It's also a lot quicker - I'll time it next time it felt twice as fast. Seems good and I'll probably buy a full license

  47. All, so following my 'reset' with my RPi / Astroberry / KStars/EKOS and I am temporarily using a separate power tank to power the dew straps until I source a separate power supply. I had 5 hours of relatively clear skies last Wednesday night and no RPi crashes - it all worked as it should. I decided to image NGC7000. Although it is near the zenith, which is good astro imaging wise, not so good when I have a SkyShed POD and no zenith table, I did my usual push off the dome and balance on my shed roof, but this time the shed moved and the dome fell off or rather dropped down between the shed and POD wall 😮 - Ooops - no harm done to dome or shed and I now had a full 180deg of sky to work with during the imaging session, but I had to climb in and out of the dome over the skyshed wall as the dome had blocked the door.. all sounds a bit mad writing this up , but I got my image and thats what counts 👍 A bit of leverage and some bits of wood and dome was all back in place and functional the following afternoon.. Anyway on to the image. So this image is 4 hrs of 120s subs taken with ASI2600MC-Pro using an Optolong L-Extreme filter and 1 hr of RGB subs taken though a IDAS-D2 filter. The raw L-Extreme image had loads of detail, but as I am now finding out very flat and mostly red. I used the tutorial https://www.stastrophotography.com/creating-a-hubble-palette-image-from-osc-dual-band-data/ This is a Pixinsight based process, and works exceptionally well although it does take most of the green out of the backgound which makes black look odd - so I used a processed view of L-Extreme as a luminance and added it to the Synthetic SHO with a mask layer and that corrected the backgound reasonably well. I also recently recently managed to buy a Nvidia graphics card (RTX 3060 ) and have used the Starnet 'Hack' to use CUDA/Tensorflow GPGPU processing to remove stars - it works amazingly well, Starnet now removes stars at stride 32 on this 26Mpixel image in about 10mins !! So using this improved Starnet process I removed the stars and replaced them with the stars from the RGB image, in hindsight I think 120s on RGB was too long an exposure and I should have halved the exposure to get better star colour as 120s has rather overexposed the stars and lack the colour depth I wanted to acheive. I am very pleased to get such a close rendition to SHO from dual band filter on a OSC camera Bryan UPDATED : I have watched the youtube video referenced by many by lukomatico - How to get Hubble style prictures from OSC data - Easy Pixinsight Guide This is the result, hard to believe both images came from same base dataset

  49. I captured this early 2020 with my ZWO ASI183MC OSC. Pixinsight have just released WBPP 2.2.0 and I thought I would run some old data through the new script to see what it could do. One of the features is to split the RGB image into separate greyscale frames and align all 3 channels to avoid the colour fringing you sometimes see at the edge of field - especially on scope like SCTs which sometimes show red fringe on one side of a star and green on the other side. So I ran the Owl and Surfboard (I think it is also called The Hockey Stick Galaxy too) and was pleased with the results.
