  1. Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set. Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment. Besf regards to everybody
  2. Hi Guys, I present you the second image taken with my Moravian G4-16000 camera mounted on my modified TeleVue NP101is. Images and technical information below. M13 globular cluster and its galactic area : Full Resolution image 4k x 4k here : www.poigetdigitalpics.com/G4-16000/M13.htm Full Resolution image here : http://www.poigetdigitalpics.com/Fichiers_Divers/M13new_image_Annotated.jpg Enjoy ?

  3. The Leo Triplet - a target that I needed to image again as previous efforts haven't really done it justice. This is the most successful attempt so far, largely thanks to the ZWO ASI1600MC Pro camera and by giving it plenty of exposure with not too much gain making for a smoother background and bringing out dust lanes and other details in the galaxies. 014 x 090 second exposures at 161 Gain cooled to -20°C 081 x 090 second exposures at Unity Gain (139) cooled to -20°C 010 x 120 second exposures at Unity Gain (139) cooled to -20°C 016 x 180 second exposures at Unity Gain (139) cooled to -20°C Total integration time = three hours, 30 minutes and 30 seconds 149 x dark frames 116 x flat frames 200 x bias/offset frames Captured with APT Guided with PHD2 Processed in Nebulosity, Fitsworks, and Photoshop Equipment Telescope: Sky-Watcher Explorer-150PDS Mount: Skywatcher EQ5 Guide Scope: Orion 50mm Mini Guiding Camera: ZWO ASI120MC Imaging Cameera: ZWO ASI1600MC Pro Baader Mark-III MPCC Coma Corrector Light pollution filter
  4. It's been a while since I posted anything here so here is my latest image. I'm starting the new year with a new camera (Zwo ASI 1600 MC) and I'm learning how to use it so I've been experimenting with different exposure times and gain settings (in this shot I mixed various exposures at Unity Gain with some at maximum gain to see what came out). I'm pretty pleased with the result but this was really just an experiment - in future I'll have a better idea as to what settings to use in order to reduce noise even further - but wow, what a difference from using a DSLR. Now, if the weather would only improve...
  5. Check this out ! http://www.bbc.co.uk/news/uk-england-nottinghamshire-36678394 The good professor talks about how the image was put together on the BBC video at the link. Awesome Space Ranger.
  6. Taken 30 Nov 17. 30 subs of 120s Flats/bias/darks x 10 each. Atik 4120EX OSC camera Celestron C11 with Hyperstar Mesu 200 mount. Quick process in Pixinsight. Thanks for looking.
  7. This is a shot I've wanted to try for years. It's an experiment in taking guided shots with an EQ mount and an assembly of lenses to get a focal length of 400mm which is perfect for framing this object. All in all, I'm quite pleased with the result. 53 x 2 minute exposures at 400mm f8 - 400 ISO (1 hour and 46 minutes) 22 x dark frames 23 x flat frames 20 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity and Photoshop Equipment: Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 500D DSLR Takumar 70-20mm lens with x2 TeleConverter
  8. Hi guys, This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K). The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention. For a precise collimation, i use the CATSEYE XL & XLKP kit. This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.

  9. Yet another Markarian's Chain image. I tried to ' dither' between shots (with the camera, that is, as opposed to me dithering) for the first time ever, but the tie it takes to dither meant that I lost 30 minutes of images, so this is based on around 80 mins (180 s exposures at iso 1600). The Astrometry images shows why this is an amazing sight in the sky - how many civilisations are there in those galaxies?
  10. Hello.. First of all would like to say thank you to everyone who has helped me narrow down and help me decide what scope I should get has been a long month trying to decide The scope I’ve decided to go for is the AZ Pronto and 130p as it’s the best one I can afford which suite my needs..( could’ve gone bigger but had to lower my budget ) im going to mainly be using this scope for hunting faint fuzzies ( Clusters and Galaxies). My skies are reasonably good, I don’t suffer badly from light pollution. As I have not used a proper telescope before as I have mentioned I wanted to know what is possible with this scope as I don’t want to set my expectations too high ( not expecting Hubble images). Would I be able to make out some of the ngc galaxies near Triangulum for example? Even if they appear to small and faint? Even if they don’t have any detail I just find it fascinating that we can see objects that are so far away.Would also hope you could give me some targets for me that I should look for when I get it which will hopefully be very soon I have turn left at Orion which I’ll have another read through but wanted some of you to tell me your experiences if you’ve had the 130p again thanks for all the help in the previous posts and of course in this.
  11. Hi all, Sorry if this has been asked before but every time i do research in to this i get different answers from different sauces. Not sure if im looking at out dated information or not so im hoping if i ask my questions here i can get the most up to date answer. So my questions are; 1. How many Stars are their in our Galaxy? 2. How many Galaxies are their in our Local Group? 3. How many Galaxy Clusters are their in our Local Supercluster? 4. How many Superclusters have we found so far? 5. How many starts in total are their in all of the Superclusters?
  12. Had a productive observing session couple of nights back. It was clear with low humidity which always helps with transparency. Unfortunately the light pollution is pretty heavy here (white/red zone) hence it is hard to get a dark background or a smooth image as a high contrast stretch is usually required (I don't use LP filters). First up is the Coma (Abell 1656) and Leo (Abell 1367) clusters of galaxies which are part of the Coma supercluster and are ~300-330Mly from Earth. The Coma supercluster is the nearest supercluster outside the Virgo supercluster (which we are part of). Wrt the large scale structure of the universe this cluster is part of the Great Wall which is one of the largest structure known to us. The Great Wall also includes the Hercules superclusters. The Coma Cluster has 2 supergiant elliptical galaxies at it's center. NGC4884 (4889) and NGC4874. Some more galaxies from the night. M61, M88, M99 and M100 all yielded some excellent detail in the spiral arms. M61 is classified as a barred spiral but what is unique is the elbow shape in the main spiral arm.
  13. Had a good 2 hours observations tonight with my Skywatcher Startravel 120 refractor. First off looking at Jupiter, which was nice and clear to look at tonight. Seeing was again 3.5 to 4, and saw nice details on Jupiter's surface. GRS was observed very easily later on at around 11:15pm when near to the centre of Jupiter. Used my blue filter and got good detail showing, however when seeing allowed you could see OK without the filter on too. I also tried to find the Leo triplet of galaxies which I'd never seen before. After a little hunting around, and finding the righ location, I honed in on M65 & M66 OK. These two little fuzzies where quite easy to see, and could see also without having to avert the eyes also. Best seen with my 17mm Skywatcher plossl EP at x35. Was very pleased to see these and before I knew it time was flying past. Tried looking for the third member of the group (NGC3628), but never saw it alas. If I had some darker skies I may have nabbed that too. Very pleased to have seen the othe two Messier's from my light polluted back garden anyway, so at least now I know where they are I can try again another time to see all three.
  14. M81 or Bode's Galaxy on the left and M82 or Cigar Galaxy on the right. Two favourite targets that are fun to image. Every year I try to get more detail out of these galaxies and this is the most detail I've managed to squeeze out so far with more of the disk of M81 showing and hint of dust bands. There are 40 minutes of exposure here (I wanted more but cloud and guiding issues curtailed the number if images taken - still, I can always add to it. These two galaxies are both about 12 million light years away from Earth and can be found in the constellation of Ursa Major. 5 x 8 minute exposures at 400 ISO 10 x dark frames 21 x bias/offset frames Guided with PHD Processed in Nebulosity and Photoshop Equipment: Celestron NexStar 127 SLT GoTo AltAz mount with homemade wedge Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  15. Despite all my weather apps predicting cloud the night was unexpectedly clear (ish) with just the glare of the Moon and some some patches of thin high cloud to contend with. I wasn't sure how much of the three galaxies would come out as very little was visible on the subs but I was pleasantly surprised. M65 (bottom right), M66 (bottom left), and NGC 3628 (top). 1 hour and 25 minutes total integration time 68 x 75 second exposures at 400 ISO 29 x dark frames 52 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity, Maxim DL, and Photoshop Equipment: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  16. This one didnt quite go as planned, i think i might have tried to overcorrect for alot of things during post processing, but i might as well share it with you guys anyways. Then again, perhaps i've just stared too much at it during processing.. Anyways, i hope you like it m81 & m82 LRGB L 74 frames of 180s = 222 min R 41 frames of 180s = 123 min G 40 frames of 180s = 120 min B 38 frames of 180s = 114 min Total int. 9,6 hours 8" Reflecltor telescope ZWO ASI 1600mm camera Eq6-R Pro mount L 74 frames of 180s = 222 min R 41 frames of 180s = 123 min G 40 frames of 180s = 120 min B 38 frames of 180s = 114 min Total int. 9,6 hours
  17. So,after observing in my backyard for a month + (visible targets only in orion taurus auriga and monocerus) , i ve decided to start observing from my front yard.Now ,i see a whole new sky Ursa Major Leo, Virgo and more.A week ago , was the first time i saw a galaxy.To be exact,m81,m82 and m64.I cannot describe what i felt when i took a look throught the eyepiece,i was amazed.Even though they were just faint fuzzies with no detail whatsoever,it was magestic. Then, i tried to observe m51 and m101,with no results.I ve read reports that m51 is a quite bright and obvious galaxy .If so,why cant i see it? Also,can anybody give me advice as to what to observe in and near ursa major?I ve made my own star charts for M81 M82 and M64 and now need more to further advance my Views of the messier objects.Thanks Kronos

  19. Work in progress Started this Saturday night. I love these galaxies and been wanting to image them a long time. So far, only 30 x 60s L and 10 x 60s RGB. C11 with focal reducer (1760mm), ASI183mm Pro. Astrodon filters. Mesu 200. Pixinsight. Thanks for looking Dave
  20. Having had such a great experience with the Orion Nebula, my next target will be the Andromeda Galaxy! My Sky Safari app tells me it should be to the west northwest near the zenith. I assumed it would be visible to the naked eye but I can’t find it. Am I just not looking hard enough?
  21. Took this photo of the Markarian's Chain during my visit to Namibia in April 2017. Photo Details: 8 x 10Min Lum channel. 15 Min for each RGB channel Telescope: ASA 12'' F3.6 Mount: ASA DDM85 Camera: FLI8300 Mono with Astrodon filters Thanks for watching, Haim Huli
  22. An annotated an unannotated segment of Markarian's Chain which I'm targetting for the first time. I'm planning to get some more shots of the chain and stitch them together in order to show all of it, so this is just a first panel and a test of exposure and processing settings. This image is made from 29 x 30 second exposures at 3200 ISO and 18 x 30 second exposures at 6400 ISO plus 19 dark frames, 16 flat frames and 48 bias/offset frames (applied to flat frames only). Total exposure time 23 and a half minutes. Images taken on April 30th 2015. Processing was done in Nebulosity and Photoshop.
  23. M81 and M82 are two targets I love coming back to every year as each attempt yields more detail. This time, using the f/5 150mm Newtonian with its shorter focal length, the galaxies came out better than ever. It was a lovely clear night for imaging with good seeing and low humidity so a perfect time to see what this scope can really do. 77 x 75 second exposures at 400 ISO (1 hour and 36 minutes total integration time) 29 x dark frames 79 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity, Maxim DL, and Photoshop Equipment: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  24. Stunning transparency from 3-5.30 am. The seeing wasn't up to much , enough to spot a small dark barge on the northern belt of Jupiter . Some good colour and fine belts , just set the focus and watch them drift in and out. 150 magnification produced the best results. The sky must have been severely washed of muck. Just stepping out of the back door , it looked stunning. Just set up the Newt (yikes !) and got the focuser nearly opposite the weights. This gave good comfort to the north , east and swinging around to the south . M51 looked spectacular with clear structure to NGC 5195, the zenith being very dark. Canes Venatici ,Coma Berenice's , and Ursa Major providing the best views. Both Virgo and Leo were high above town lights with little contrast. A lovely galaxy session catching, NGC 4631 (C32), the elongate "whale" right up to x120 where it streaked across the fov. NGC 4656/57 averted view of the "hockey stick". NGC 4214 an irregular bright +9.7 galaxy. NGC 4490 a bright "cocoon". NGC 4449 (C21) delightfully granulated , resolves into stars. NGC 4565, the bright "needle". NGC 5005 (C29) lovely and bright. M63, the "Sunflower", M64 and the very bright M94. Very very pleased to see the galaxies again, especially the leaping whale,not a scene to be missed in the early hours. Air is still, lights are off and it's magic. Had a look at M3 , resolves into a sparkling globular with bright surrounding field stars. Quite bizarre to see from Vega,the whole of Cygnus up with Hercules very high. Enjoyed M13 and M92. The most stunning view was "Bode's" ,where the fov was filled with stars. This compared very favourably with the view from Skye with stars close in to M81.Yet again no sign of Comet V2 Johnson in Bootes. I scanned the area several times , but nothing not stellar even at x120. It got quite chill , had to reset the collimation. I do like this scope, it's almost as good as a frac, but opens up some deep sky. Clear skies and early mornings ! Old Nick.
  25. M5 globular cluster I've been using my binoculars to look for objects that are obstructed from where I usually place my telescope in the back garden, and to plan star hops to objects I haven't otherwise had the chance to look at. I went out on the night of the 17th to look for the globular cluster M5, which will be determinedly behind a tree for my telescope for quite a while, and I found it quite easily by wiggling my way down, via a number of steps and a dog leg, from Arcturus. I found that it was relatively large and bright and still fairly obvious despite it having a low elevation, at the time, and somewhat in the murk. M3 globular cluster I'd looked for this with my binoculars during a clear spell on the previous night after an abandoned session with the telescope (had it all set up and aligned when the sky clouded over just as I got my eyepieces organised). It was clearer on the 17th and it looked really marvelous. M13 globular cluster I noticed that Vega had cleared the neighbour's trees and it was an easy hop to the keystone and then on to M13 itself. I find it easy to locate now and, as it forms a tight little triangle with an "equally" bright pair of stars, it's quite unmistakable. It's really spectacular and a real favourite of mine. M92 globular cluster I always find the hope to M92 tricky as it does involve a little bit of a leap of faith from the keystone to find it - which I've found awkward through the telescope finder. It's a bit easier with the bins, though M92 is more compact and fainter than the previous globular clusters and I find that I need to have my eye in so that I don't sweep past it. M53 globular cluster This was the last globular cluster that I visited and it was the faintest so far - though unmistakeable once I'd really fixed on it. M81 & M82 galaxies (Bode's nebula & the cigar galaxy) I always visit these when I have my bincoculars on me. They are easy to locate, reasonably large and fairly bright (for galaxies). I find that it's just about possible to make out the shape of each galaxy. Even with the moon on that evening both objects were very distinctive. I then went on to have a look out for other galaxies in the region of The Plough to see if any of them could be seen, despite the moon. M51 The Whirlpool galaxy I find this quite easy to locate, after having it viewed it numerous times, and it appears as a small fuzzy patch which isn't too difficult to pick out - though, as with the other galaxies, you really need to know where to look. M63 Sunflower galaxy Heading in the same direction away from Alkaid is M63 and I locate it by looking for a reversed 7 group of stars which points like an arrow at the galaxy. Despite it being realtively easy to locate it's actually quite tricky to observe. I could just discern it as a very faint patch with averted vision. M94 galaxy Continuing along to cor carole and then up to a very faint group of stars that look a bit like a mini version of the plough. M94 is very roughly 3/4s of the way between cor carole and this little group. I wasn't expecting to see the galaxy but it was just about visible with averted vision and moving my eyes from direct to averted vision. M106 galaxy I get to this object via a hop from phad. It's nestled in a group of faint stars which pinpoints in quite tightly. This was, again, just about visible with averted vision. M101 Pinwheel galaxy This is not too difficult to find via a star hop from mizar and alcor. I had to do a lot of checking in Stellarium to make sure I was in the right location via the faint surrounding stars. It was just about visible despite its low surface brightness. I certainly had the impression that it was larger and more diffuse than the previous galaxies - though this could just have been wishful thinking. I wound my session up after this last object but I had quite a good haul for the evening and I had a new Messier (M5) to add to my list.
