  1. From the album: Solar Images

    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

    Moon

    From the album: Jammy Astro

    4 part mosaic from C9.25 and dslr
  4. 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.
  5. 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.
  6. 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.

  7. 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
  8. 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.

    Lunar Mosaic from 5/3/2014...before the clouds rolled in
  10. 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
  11. 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!
  12. I finally got around to finishing my lunar mosaic from April 20th... http://zoom.it/CkFj#full

    Moon Mosaic

    From the album: Lunar Images

    Mosaic composition of the near full moon taken 26th December 2012 from Wimbledon backgarden. The composite is composed of 21 single images taken using C6SE with the Baader 2.35 x Barlow attached to Canon 1100D (ISO200, 1/25s). The image was composed in photoshop, with sharpening applied.No adjustment to curves or levels, just the neutral response of the camera is given here.

  15. 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
  16. 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.

  17. 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
  18. 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/
  19. 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
  20. 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
