From the album: Deep Sky Imaging
A widefield three plate mosaic image of the constellation Orion. Imaged in natural color with added Hα and OIII narrowband to the LRGB data. Orion is easily identifiable in the sky between November and February, but long exposure photography reveals the immense amount of nebulosity within that is hidden from view. Exposed between 23 November and 28 December 2022 using a stock Canon 40D DSLR for the color data and a QHY 268M mono camera for the HAlpha, OIII and luminance signal through a 80-400mm f4 lens set at 80mm. Exposures Plate 1: DSLR RGB:17x60s, 17x120s, 17x180s @ ISO1600, Ha:18x300s & 15x180s @ HCG:62/OFS:25 (3h57m) Exposures Plate 2: DSLR RGB:18x60s, 18x120s, 17x180s @ ISO1600, Ha:18x300s & 12x180s @ HCG:62/OFS:25 (3h51m) Exposures Plate 3: DSLR RGB:17x60s, 17x120s, 17x180s @ ISO1600, OIII:6x180s, Ha:14x300s & 9x180s @ HCG:62/OFS:25 (3h37m) Exposure Time was 11 hours and 25 minutes.© Mariusz Goralski

Some time ago, I comment in the Samyang 135 Mega-Thread that I had resolved most of my issues with this lens, specially those regarding backfocus. Not perfect but well enough to deserve some fun imaging. So... I planned a large mosaic of the Cygnus region: As this is a large-term project, I've planned to open this thread to comment on my progress so I can ask for advice and critiques (and you can gossip if interested 😉). So... there we go! This is a proof of concept shoot to test if the whole idea is feasible and make sure I can fix anything prior to the actual shooting. Some details: Main equipment: EQ6-R Pro + ZWO ASI183MM Pro + Samyang 135mm f2 (@ f2.8) + Baader SHO 6.5nm Narrowband Filters Other equipment: ZWO EFWmini filter wheel + ZWO EAF focuser + ZWO ASI120MM Mini + William Optics UniGuide 32mm + Astrodymium Ring System Imaging: 4x3 mosaic with 1x300s Ha + NINA for planning and data acquisition. Conditions: Bortle 4 backyard according to LightPollutionMap (probably Bortle 5 now) with some streetlights pointing towards my telescope placement. Processing: data calibrated with darks using WBPP and merged with GradientMergeMosaic with Pixinsight. Simple STF applied, no further processing. My OTA doesn't have a rotator so adjusting orientation is a bit of a pain due to the belt-system focuser I use. So I had to carefully select the orientation and panel disposition so I can get individual panels as 'interesting individual pictures' while adding more integration to the mosaic. My initial plan is to build a 'base' mosaic with 12x300s per filter (SHO) per panel: (4x3) x (3x1h)=36h total. Then, I can add more integration up to 3h/filter: 3x36h=108h. I know this is quite ambitious for my sky conditions -clouds and rain most of the year- and my skill but, well, it will be fun and I won't have to rack my brain choosing targets for a while 😅 Feel free to ask, critique, correct or whatever, any comment will be welcome!

Hopefully I can submit to the SGL galaxy challenge June 2023, it was ready on Wed, uploaded Thu... This challenge always attracts many excellent submissions and this year follows on with the trend. Some truly excellent pieces of work there. I decided to divert from the general consensus, something I’ve wanted to do for a number of seasons but it’s always difficult with short nights and non astronomical darkness, but I never like to leave a clear night un-imaged so even whilst imaging right next to the moon I wanted to do this… try and image the most amount of galaxies in one wide FOV image. This is my first mosaic. Originally when planning this mosaic I went nuts and wanted to include the whole Coma Berenices region downward, but it was a 75 panel mosaic, impossible for one season (and truly will take years) and I can’t image the whole thing as maybe half is below the horizon, checking the framing would also be a nightmare so I decided to simplify and start with that often imaged target Markarian’s Chain, a wonderful target in itself but also an ideal datum point to start from and work outward. The original plan was to image luminence with one scope, and r, g, b with another, I nearly managed a 20 minute per panel pass of the colour but stopped short on the blue due to time (lower panels set too quickly after dark and they really need longer imaging time overall per filter). The weather’s been decent of late during the day but come night the clouds like to roll in, and if not that the wind decides to turn up and the usual suspect the moon is where I want to image like it reads my mind. The last session I got fed up and imaged next to the moon, data wasn’t bad, wasn’t the best either but I decided not to use it. So every time I’ve imaged wide with my excellent Z61, my second setup has also been imaging but I decided not to use that data, mainly because it was a smaller field of view and trying to match everything will have been a massive undertaking. Even this simple end result rough as it is with many defects (and I may have destroyed a few trillions of innocent distant civilisations in the process when cleaning up the image) took probably longer than the image acquisition as it was stacked and pre processed in Siril and aligned and colour matched and cleaned up manually in PS. No auto stitching software worked because when cross referencing the auto stitched images with object positions on my manually aligned image and referencing Stellarium, the auto software scaled and rotated panels in odd ways causing distortion so I don't believe they stitch accurately. So in the end I only managed a 3 x 3, 9 panel mosaic approximately 8 x 6 degrees FOV at 1 hour per panel (dropped to 54 minutes with final stack rejection). The image won’t win any awards but I’m submitting it, it’s my first attempt at a mosaic, and my first attempt doing a wider than normal field of view, hopefully some viewing it will like it, even better if it inspires others to attempt similar. Think I may add to it per season…… Best viewed at 100 percent, I’d recommend you try to count as many smudges you can see on the plain image first. Once you’ve done that come back to the below. For reference this is the astrometry plate solve on a lower res version, around 317 objects annotated: And by my rough observation this many are visible (160 odd), think this is quite the result for such a short imaging time. It’s amazing what’s possible nowadays.

Just a quickie, I took a shed load of images last night of the moon using my DSLR on my scope with the intention to stitch using Microsoft ICE but its been pulled! Any free software suggestions for image stitching (not stacking)?

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.

processing 99% Moon Mosaic
Adaaam75 posted a topic in Imaging - Image Processing, Help and Techniques
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, -
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.

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.
