  1. From the album: Lunar Images

    Lunar Mosaic taken on 17/2/2013 from Wimbledon Backgarden around 18:00. Taken using C6SE with x3 Barlow using Canon 1100D 1/25s ISO800. Assembled in photoshop.
  2. From the album: Images

    Lunar mosaic made up of 13 ish panels. 200p f/5 with point grey firefly mono. I've spent far too long trying to get the background how I like it so I've given up whilst I'm reasonably happy with it.

  3. You could call this my first proper attempt at andromeda, thought I've imaged it quite a few times now. But this is the first time I've managed to get most of it in one picture, which required me to do a two-pane mosaic. The left side of the mosaic is stitched 27 subs of 2 minutes ISO 3200, while the right side is 28 subs, + 1 sub of 8 minutes ISO 800 (just to test what difference exposure contra ISO does to details). I am very pleased with the result of it, but I also discovered some of the pains of doing mosaics, as getting an even background was very hard. Gradient X-terminator would do a decent job, but couldn't quite nail it, so I used it in conjunction with a few other techniques. The stitching was easy and painless, as I just used Microsoft ICE. Some feedback on the processing would be lovely, as I am not sure if this is my final version. I've starred myself blind processing it.. 2-pane mosaic 56 subs (ISO 3200 and 800) 2 minute exposure (+one 8 minute) 1.96 hours Total Exposure Skywatcher 150pds Celestron Advanced VX Mount Nikon D5200 Explore Scientific HR Coma Corrector 7235x5838 pixels Stacked with DSS, stitched with Microsoft ICE, processed in Photoshop CS2
  4. 7 panel lunar mosaic from 12/10/2017 captured with skywatcher 120mm (F8.33), & Lumenera 2-1M. Best 75% of 1150 - 1350 frames were stacked for each of the 7 panels (frame rate kept dropping) then sharpened in Registax6 before stitching them together in PS6 using the photomerge option.
  5. Finally got round to starting a proper mosaic in SGP, and putting skills in PI into practice from Warren Keller's excellent book! This is not a fully processed image by any means, just a 1st attempt at the alignment workflow for the mosaic. T: Skywatcher ED80 M: EQ6-AZGT C: AtikOne G: AtikGP F: Luminance E: 4 panes, each 6 x 300s; fov for each pane is 1.19 deg x 0.95 deg; Basic Process in PI: Calibrate Cosmic Correction Star Align Image Integration Crop ABE Star Align for Mosaic ABE Histogram Curves So, pleased with the outcome - cannot see the seam at all. Yes, the data is noisy - rejection needs tweaking and needs heaps of data, but the workflow for creating the mosaic makes sense having run through a few times tonight!
  6. Moon Mosaic: Coachella Valley Astrophotography 7-17-16 This is not your typical Moon picture, but a mosaic of 11 pictures of the Moon stitched together to create a very large and detailed image. This was actually created using 11 short video clips: I pointed at one part of the Moon, took a short video at 64 frames per second, and then used stacking software which picked the best of those frames and added them together to produce a single image. I then moved the telescope to a different part of the Moon and repeated the procedure 11 times, until I had images of the entire surface of the Moon. These were then processed to sharpen the details, and finally stitched together to create the mosaic. Taken 7-17-16 in Cathedral City, CA Nexstar 6se + 6.3 focal reducer asi120mc-s camera 64fps 3000 frames per video 11 videos total Dimensions 3300x3100 http://coachella-astronomy-astrophotography.blogspot.com/2016/07/moon-mosaic-coachella-valley.html
  7. My first proper mosaic (2285 x 2246) of the waxing gibbous moon of the January 22, 2016 taken using A C11 Edge and unmodified D7200 at prime focus. Frames from 9 x 10 second AVIs were stacked using Autostakkert2, sharpened and then assembled using PS photomerge. I also did a little tweaking of brightness and contrast in PS. I'm quite please with the results but would gladly hear comments :-) R:)
  8. A few firsts on this one.. Managed to dodge the clouds & showers Sat night & grab First Light for the QSI683wsg-8 & Astrodons, my first mosaic and first time I've bothered to image these targets as I've never been able to fit them in! This was just supposed to be a couple of test targets to get an idea of the FOV & flatness but I got kinda hooked in processing & ended up putting them together. So there's a bit of cropping as it wasn't planned. This really is a nice camera.. what a difference after years with the faithful 314's. Think I'm hooked on hoovering up the sky now... this is most definitely a work in progress.. Only calibration is Bias. No Darks or Flats NGC7000 6x900 IC5067 7x900 Astrodon 5nm Ha
  9. Here's some F30 mosaics from this mornings session at.. some ridiculous hour that not many people know exists. F30 is as far as I can push my scope using my Televue 3x barlow. Its not often the seeing is good enough to make it happen using only an 8 inch aperture scope either. All shot through a red filter. Can't do much more to reduce the noise in these when working at this focal length, its a by product of the lack of aperture. First up is a 6 pane mosaic of Moretus Followed by a 13 pane mosaic of Plato and surrounding region And then a 5 pane mosaic of Copernicus and finally a quick shot of Tycho

  11. Second time I undertake this kind of endeavour. Many many movies were shot. Over 300Gb of data. Stitching was done by hand. in adobe Photoshop. Equipment used: CFF 300f//20 cassegrain ASI174MM with Astronomik proplanet807 processing using Autostakkert, lynkeos and adobe photoshop. Image is a wee bit too large to add to post direclty. hence just the link. https://astrob.in/400728/0/ Make sure to check out at full res. enjoy. Wouter.
  12. Hi everyone, A bit of an odd one aspect ratio wise, but fun to put together - first light for my new ASI294MC OSC and technically my first experimental attempt at a mosaic! My first stab at using the camera meant I went for 30 second subs, I need to experiment more to settle on my ideal sub length...still, the results are decent for a low integration time of 1.7 hours. I love the Orion constellation and if I had the skies and time, I would mosaic the whole thing, but failing that, I can do bits and pieces! Orion's Belt is amazing to me, the three stars, Alnitak, Alnilam and Mintaka, very distinctive in the night sky. Full details on Astrobin. Thanks for looking!
  13. Hi all, Not posting much in SGL of late but I am still imaging as much as I ever did. Here's a 166-pane hand stitched mosaic from August 10th when the Moon was at last quarter phase. The separate panes were caught between 04:06 and 04:49 BST using a C-14 at prime focus and a PGR Flea-3 camera. The image is too large to show in one hit so I'm presenting it in a zoomable format - just follow the link... http://www.zoom.it/ephS#full Best regards, Pete
  14. Hi all, Here's a full disc mosaic taken this afternoon. A fairly quiet Sun at the moment although there was a bright northwestern prom visible and a lovely southeastern filament, rotating into view. Mosaic is made up of 20 panes, hand stitched together. Best regards, Pete
  15. Hi, although Ive been doing lots of deep sky imaging Ive not really done any serious lunar imaging at all. Here is my first try with ASI1600MM-C and 12" f/10 Meade SCT on EQ8. I took 4 panels with 850nm IR pass filter, 20 frames stacked in each panel out of 500. Image is quite large, at 1:2 scale out of the original. There is plenty of intresting details around Mare Crisium. Unfortunately seeing wasnt stable enough the top panel would be as sharp as the rest is. Still Im quite happy with the results. C&C welcome.
  16. I took this image on the 4th Nov over the space of about half an hour from 2215UT. This mosaic is made from 18 frames, each of them is 3000 frames, with the best 12% stacked within Autostakkert2. Total data size was 52.6GB - all using an ASI120MM through a 350mm newt at f4.52 with a 742nm nr-IR filter. Each of the frames was processed identically in Registax6 with Wavelets, etc. and then saved as a fits file. At this point, I took the images into ICE and combined them into one large mosaic, and then post processed in PS (levels, slight smart sharpening, curves and background levels). I did also try using photomerge in PS CS4, but interestingly, ICE did a better job (marginal, but there were a couple of edge artifacts with photomerge). Beware for those on slow connections: the full size file is quite big at 7.3MB, even as a jpg...thanks for looking!
  17. It seems that none of my glass optics doesn't want to play nice anymore. I started this 2 panel mosaic while shooting for the bubble area, on Ha, with the Canon 300 F4 L lens. In the beginning it went better, but at some point the IS elements decolimated and I just couldn't luckily align it ok again (by attaching back to the camera and focusing with the IS on and then detaching it). I tried one round with the O3, but then I switched to the Tair 3s. The total on this target is like this: 6 h of Ha on each panel, 1:x h of Canon O3 + 1:15 of Tair O3 on each panel. That means ~17h in total. I might want to try to add more O3, but it's only a hope. The moon comes again and the forecast doesn't seem nice the next days. I need a proper scope. I think now that the Soul is stretched more than the Heart, it didn't seem last night. Full res here: https://drive.google.com/open?id=0ByhJ_xuQxcnjZlQ2Rkw3NUR2S0U Thoughts welcomed. Clear skies, Alex
  18. Finally got round to using ICE for the first time on this 2 pane mosaic of the full moon from several weeks ago with my Mak and Canon 1100D. Was pretty easy to do and I'm really impressed how ICE does it all automatically. A little blurred but hey, user error... ?
  19. First lunar mosaic attempt here. 8 images from 12 videos of 1800 800x800 33fps on ASi120 mono through a NA140SF Vixen. Processed in AS2 for stacking, registax for wavelets and Maxim for stitching. Quite happy with this - gonna get it printed. Cheers Mike
  20. Woke up for a 2AM moon mosaic. It was cloudy with a few drops of rain when I first looked out, but I gave it 30 minutes as all the weather apps were showing a clear break and low and behold, the clouds parted for an hour for me to do my stuff. First mosaic with the 130P-DS and it was lots quicker than doing it with my 200p due to the decrease in magnification. Taken with a 130P-DS, HEQ5, QHY5l-iiC. Approx 11 panes in this image of varying qualities.
  21. Hi guys!I finally managed to decide I'm done processing my insane photoproject of digging deep inside M31.Long story short: One picture of M31, 27megapixel 2x2 mosaic, +3 months of imaging in crappy weather, 18 separate nights, 534 separate exposures, +150 hours of processing, 1233 manually annotated objects inside M31.(images in the end of this post, lots of "bla bla" first)I had a great start last autumn with loads of clear nights, which made me think it be a quick stab to make a 2x2 mosaic (my first mosaic btw) of M 31 since my f.o.v is to narrow to capture M31 in one frame...But pretty much as soon as I started, the swedish weather turned into a mess which made me shoot M31 during 18(!) separate nights, during more than 3 months(!).I also spent countless of hours studying the M31 Atlas available online at: http://ned.ipac.caltech.edu/level5/ANDROMEDA_Atlas/frames.htmlIt contains +40 annotated plates of M31 captured with Kitts Peak 4m telescope and contains +1000 globular clusters, open clusters, stellar ascossiations and dust-clouds inside M31.By looking at those charts, I manually annotated 1233 objects in my image, along with names & outlines (except for dustcloud-names, since it cluttered the image too much)Here's what I found within my image:232 Globular Clusters235 Open Clusters140 Stellar Assosciations626 Dust CloudsData captured using ACP + SchedulerCalibration was done in Maxim, registration & stacking + mosaic-merging done in PI, the rest in photoshop.Gear:Telescope: Orion Optics AG12Camera: QSI 583 wsg-8Mount: 10Micron GM 2000 HPSGuiding: UnguidedSummary of exposures:Lum: 364 x 180s / 1092 minutesRed: 39 x 300s / 195 minutesGreen : 36 x 300s / 180 minutesBlue : 43 x 300s / 215 minutesHa : 52 x 900s / 780 minutesTotal time: 2462 minutes / 41 hoursHere are a few 100% crops so you can appreciate the level of resolution and the hard work behind it.(note Hubbles famous Cepheid, marked as "Var 1")Also, here's one of the charts used for annotation along with a matching crop from my image:If you're not using a mobile device, I highly recommend following the links to my homepage where the image is presented in full resolution along with selectable annotation-layers containing the following:Globular ClustersOpen ClustersDark NebulaeStellar AssociationsGrid + DSO'sIt was really mind-boggling processing a image of this scale, realizing that all those fuzzy spots visible inside the galaxy are actually open clusters and globular clusters, along with Ha-regions and much more!Unfortunately mobile devices usually downscale the huge 27MP resolution images and have trouble with the annotation-layers, so if you're using a computer(highly recommended), click the following images to be taken to my homepage where you can select which layers of annotation to be displayed, as well as the choice of 3 different resolutions.

  22. Here is a mosaic my 14 year old and I did last night. We are sorry it is not complete :-( The missing panels went hiding and we can't find them! It was great fun doing it: He would drive the CPC800 in a zig-zag pattern very carefully using the hand-control and I would wait until the image settled before taking 100 frames for each panel using EZPlanetary and the QNH5L-II. We then processed the individual AVIs in AS!2 and used PS5 Photomerge. The original is over here: https://www.flickr.com/photos/rlsuk/13835061133/sizes/l
