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.

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!

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! -
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.

This is a 8 panel mosaic shot the other night during a clear spell. Its great to see the Galactic centre rising above the trees again! This image spans from the constellation of Cassiopeia on the left all the way to the red supergiant star Antares in the constellation of Scorpius. Although the skies are quite dark here, the small village over the hill towards the South does give off some light pollution most nights. In this image it has worked quite well in combination with the clouds. Eposure Details: 8* 20 seconds, f3.5, ISO 3200 Taken with a Canon 1100D at 18mm.

After the break to the mountain which I have dedicated to elaborate a bit of the material filed in time, I can finally go back to photograph. 22th morning, the sky would be especially transparent and clean, thanks to the storm of the night and although the meteo told about terrible seeing I wanted to try anyway due to the presence of some beautiful formations on the Sun. To my surprise the turbulence was almost absent at the begining, and I could capture sequence of images tho assemble the mosaics, but these are enough to exhaust the lucky seeing, and when I was setting the camera for the timelapse I already saw the first signs of deterioration which are then fulfilled during the shooting sequence. I tried to continue anyway stopping after just over an hour, even after a couple of hours I didn't see any improvements so I decided to dismantle everything and see what I could pull out of the collected material. In fact, this time, since next to one of the brightest prominences were visible a few spots and filaments, I wanted to try a totally different settings that allowed me to capture both the prominence that the details on the disk, which is always tricky with narrow filters. If it will happen again I'll have to keep exposure times longer to have more data on the weak details; in post processing then I had to study a totally different approach and I have had to duplicate each frame in order to be treated differently the disk and prominence starting from the same shoot. A faster method would be to work on shadows and light but noticing a loss of some points on the histogram I have taken the long way and hardworking. Since then the highly variable seeing I had to change the stacking and the final processing to try to normalize the level of detail as much as possible, I must admit that it was a work particularly long, because I has precluded the use of certain macros that usually use. Although at the end of the capture there weren't any cataclysmic events the level of detail at full resolution is good and if you focus on portions of the video and not only to the overview, you can see micro movements and evolutions. In particular I'm curious about the migration of certain points of greatest intensity next the main spot group NOAA 1820 more visible in the negative version, I usually think about Ellerman bombs but this ones were moving from the umbra and follow the filament/spicules and makes me wonder if by chance it is not a case of those phenomena recently discovered by UCLan university and still under study, in which they occur condensations of energy along the magnetic field of the spicule / filaments which radiate from sunspots by traveling in their length. Unfortunately the compression of Youtube has mixed some of the details but I hope you will enjoy it anyway. Youtube Channel- 6 replies

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

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

Here's my latest lunar mosaic from the morning of 6th September. 67 panes shot through a red filter between 12.50 and 2.30am. Followed by several hours of processing and manually stitching together using photoshop. I'm still knackered two days later. If the picture takes ages to load or you feel brave enough to view it full size (be warned, its massive) click here: http://www.flickr.co...in/photostream/

Evening SGL, though i would share my first astro mosaic. Taking on this little project was a spur of the moment decision, i made no plans for it until i imaged M8+M20 and thought "hmmmm, a galactic centre mosaic would look pretty tasty!". I then planned to create a 3x5 mosaic of the area totaling in 15 panels. But like i said, without planning it out properly i was left with the Milky Way dropping too low in my sky for me to get anywhere near what i wanted. So i only managed 4 panels... Each panel was around 70-80 minutes exposure time except one which i lost a lot of frames on because of cloud, leaving me with one panel of which the exposure time totaled 45 minutes. The processing and creating a seamless image was hard but this 'dud' panel caused more problems. I had to stretch it first and then bring the rest up to the same levels, if i had managed 70 minutes on this panel, i could of stretched the whole image a bit more without any problems. Each panel was made up of 120 second exposures at f3.2, ISO 800. And here is a couple of the single images... M8+M20, the Lagoon and Trifid And a part of the Pipe nebula, i call this area Barnard City I will be better prepared next year and will hopefully get to finish what i've started! All images were taken with a Canon 1100D and a EF200L on a Astrotrac TT320X-AG Clear skies!

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. -

Composite image of the sun using PS Elements, using images I took on 15.07.15 using Coronado PST and Imaging Source DMK21 Monochrome CCD. I didn't have enough images to cover the full disc, however I am pretty thrilled with the results -
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.

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.

Hello, It was almost a full moon and I hadn't attempted one of those yet so it had to be done! The frames are all good, this is just the first process of it all with some dodgy photo editing afterwards with GIMP I think I may have overdone the wavelets a tad, and perhaps the contrast is a little much for my liking, however I am extremely happy. This is a mosaic of around 30 panes. Each pane is a stack of 1500 frames. All taken with my skywatcher 200p f/5 with a point grey firefly mono at prime focus. I've also attached a single pane of the Copernicus area (as it came out of registax) to show the field of view I had. All comments/criticism/ suggestions for improvement greatly appreciated! Thanks, Dan

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

A very quick attempt at doing a mosaic from Afocal lunar shots. viewing was not the best, lots of intermittent fine cloud, but thought I would give it a go. Taken through a 25MM TAL Plossl, x2 Barlow (I think) wiha small handheld Sony Cybershot, then stitched together in MS ICE. will post up the other none mosaic shots as well in a minute. Thanks for looking.

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
