  1. Recently I bought a ZWO ASI178MM for planetary/lunar/deep-sky imaging and last weekend i had clear skies so I was able to capture videos of the moon in two panels. I have already processed the videos in AutoStakkert, I used 3x drizzle because I intend to print the image so now I have two 120MB TIFF images that i would like to combine in a two panel mosaic. I tried doing it in Hugin, a free panorama stitcher but the program crashes due to the file sizes being too large. I have searched for tutorials on using DynamicAlignment in PixInsight but it seems to me that i'll need a reference image to be able to create mosaics in PixInsight. Is there any way to go about this, I feel like this should be a pretty straightforward job but I am not very experienced in PI so I would really appreciate some advice. I tried using DynamicAlignment as you can see in the attached screenshot but the result was just a cut version of the target image, aligned perfectly to the source image. It would be perfect if it didn't cut off the lower part of the target image.
  2. And i will try again.
  3. Hi guys, So on Tuesday night I spent the evening imaging the moon with my Celestron 9.25 SCT and DSLR as shown below and am happy with the images I collated (I only took images as I did intend to take capture video but I got carried away and time was getting on). I have approx 350 jpeg (and the equivalent in raw) images and have used the Microsoft image composite editor to stitch the frames together without editing them first etc but I wonder if I'm going the images an injustice? I'm not ready to pay for editing software as I know there is a lot of very good free downloads out there and I'm asking for recommendations. Should I be processing the frames before/after stitching and what software would you recommend? Please offer any advice you have. I will post the resulting image once I'm happy with the outcome Thanks in advance,
  4. 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.
  5. 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!
  6. Hi everyone! The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago. A number of firsts with this image: 1. My first mosaic - keeping it simple with two panes! 2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night 3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well! APP was used for pre-processing and stitching the mosaic together, while Pixinsight was used for image processing. A total of 10.9 hours integration time. Full details on Astrobin Thanks for looking!
  7. Hi everyone. So I'm looking to do some form of mosaic over the weekend. Is it better to stack in mosaic mode in DSS or merge in photoshop? And is there any other advice for me as this is mainly a learning evening for me so any tips would help. Also do I need just 1 set of calibration frames or a set for each part of the mosaic. Thanks, Paul.
  8. 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.
  9. Heres my version of NGC 7000 and the Pelican nebula, taken back in 2015, through my William optics zenithstar 70ED with focal reducer. To fit it all in I did a 4 pane mosaic. Think the subs where 15 x 6 mins for each pane..........hope you like.
  10. 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.
  11. 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

  13. 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!
  14. 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
  15. Hello all, I started a while ago shooting the bubble and the M52, first in Ha, then RGB and then O3 too. 25min on each RGB channel, 5-6 h on Ha and 1.5h on O3. Here is the result: Then I asked myself if I should shoot L, more RGB, more narrowband or if I should go for another target. And I decided that I should try a mosaic in this area and catch the lobster claw too. The decision being took, I went below, left and then above again for panels 2, 3 and 4. R first, some of the G after. The rest of G and the B the next night. Last night I also shot 45 minutes of O3 on each of the remaining panels - 2, 3 and 4 and planning to shoot another 45 minutes on each panel the following nights, if possible. I will then leave the country for 2 weeks and I'll be back with a full moon when I will try to shoot some Ha. There will be no much time left either for this target as it reaches the limits where I can point my telescope from my balcony. I'm aiming for 1.5-2h of O3 on each panel and 2-3h of Ha this year. Supposing the acquisition can be done, I still have to stitch/process/stitch/combine all the layers. Now, this is something I've never done before and I don't know which is the best approach. I tried yesterday the new APP, I threw at him all the R subs and asked it to combine them in a mosaic way or a normal way. In mosaic it was failing with a null pointer exception and in normal way it was failing with an index out of bounds exception. So I answered myself an older question if I should wait for the APP or buy Registar and I bought the second after the first one didn't work. I registered and stacked with DSS all the R, G, B and O3 frames for each panel with the best R frames set as reference. Then I processed with StarTools each panel as RGB with the same settings and combined the RGB panels with Registar. Now this gave me a result which is almost ok, but you can see a separation line or two between panels 1 and 2 (the one with the bubble and the one below). I processed each O3 layer with StarTools applying the same settings and I combined these too with Registar. Then I split the RGB mosaic into channels and I added the O3 over the G and B channels as lighten only in GIMP and I combined back again the layers into an RGB image. I colour balanced and enhanced this result in StarTools. The result is attached. What do you think about my workflow and what approach did you find the best and how do you do it? Also, how can I normalize the layers and still be sure that I stretched them the same? There are some variables that come into play, the worsts mostly because during multiple nights I have different transparency and seeing conditions. Many thanks and clear skies, Alex PS. and an annotated version: http://nova.astrometry.net/user_images/1668494#annotated
  16. 4 panel mosaic of M106 Data: Liverpool telescope at La Palma (Canary Islands) r (sdss-r), g (Bessel-V) and b (Bessel-B) datasets, 4 x 90 seconds per channel at f/10 (but a 2 m primary mirror) My first time making a mosaic. The data was rather flat, with a very bright inner core and only faint outer arms. Even though there is no Ha data, there is just a hint of Ha jets near the center.
  17. It took me a while to process the images taken this weekend: this beautiful weather did come with a price, too many GB to process! These are from Thursday evening: an almost full lunar disk taken with my newest ASI 1600mm. Lower resolution than my other camera, and slower, but very good to get the moon in the field without stiching. The mosaic below, instead, was taken with my ASI 178mm: smaller pixel and smaller sensor, so much higher resolution, and lots more details. Unfortunately there are some stiching artifact, that I hope to remove in a future version. All the shots were taken with my Celestron Nexstar SLT 127, using my Planetary Imager software. More details about the evening in my blog page: http://blog.gulinux.net/en/blog/jupiter-and-moon-06-04-2017
  18. While looking up using mosaic images at x5 barlow to create more detailed surface images i stumbled across this.(Enlarge to see all the magnificiant detail, This is not my image and i take no credit for it). Original article Jaw dropping mosaic So now ive seen this i want to try it myself. Ive seen the option on DSS to create mosaic's but have yet to try it, or even if it would work. Anyway i jusy wanted to share this splendid piece of photography.
  19. This four panel mosaic gives an incredible widefield view of one of the most colourful regions in the night sky. A collection of intricate dust clouds, reflection, emission and dark nebulae and background globular clusters makes this a fascinating area. All data captured previous summer (end of June) in Mt. Parnon Greece @ 1430m. We finally found some time to process and merge all of them in one picture. Luminance taken by Angelos Kechagias with an Atik 428EX on a Nikon 50mm Lens, RGB taken by Evangelos Souglakos (me) with an Atik 4000 on a Canon 50mm Lens. Both lenses were stopped at f/5.6. Filters: LRGB Baader Sub-exposures: LRGB 5mins Total time: 4h per panel Processing in Photoshop by Angelos Kechagias. Full resolution in: http://www.celestialpixels.com/Nebulae/i-XSNF9zH/A
  20. 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
  21. 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!
  22. This is about as good as I'll be able to get with this Barlow lens and the humidity/heat that we are having in the central part of Arkansas. I'll be getting ahold of a much higher quality Barlow at some point before the end of the year, probably a 3x or maybe even the 5x(not sure about the 5x on such a small refractor though, and the folks I've been asking apparently want to keep this a secret).....I digress. If you have suggestions on a 1.25" Barlow in either 3x or 5x....please let me know! This is the full sized image-should be able to click and go full screen(I think). Stuff? Easy....from the ground up! Battery pack and power source for laptop and mount. Mount is still my iOptron ZEQ25GT Optic is the Orion ED80(standard, not the triplet or carbon) Celestron 2x Barlow with the red filter Camera is the Imaging Source DMK 21AU618.AS(monochrome)-having to focus through the diagonal to get enough 'travel'(sure that doesn't help the quality) No polar alignment was done, the Moon....well, it's the Moon. I set-up really close to where the normal alignment is, and called it good. After all, the sun was still up.....and the mosquitos were already feeding on me! Shot twenty-five - 1,000 frame, uncompressed, Y800 videos. Stacked those 25 videos as a 'batch stack' in AS!2. Cropped all the 'funny stuff' off in LR2015, and then selected all 25 'photos' to be merged in PS2015. Completed mosaic was then processed using NikCollection tools and some 'tweaks' in LR2015, border added in Picsas3. Scott (got the "X" too) B
  23. 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... ?

  25. 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
