  1. Equipment Used: Scope: 20” f3.6 Lukehurst Dob with Paracorr (fl = 2089mm & f4.1). Night Vision: PVS-14 with Photonis 4g INTENS. Eyepiece: Plossl 55mm (f2 x38). Background. In spring 2019 I created a Sky Safari observing list of 214 highest brightness galaxies in the night sky above. I have observed 134 of the 214 (the others have not been well placed over my garden when I have been outside). In my first pass through these 134 galaxies, they were graded 0-3 (where 3 means "clear spiral arms" and 0 means "nothing to see here!") I have now completed a second pass through the grade 2 and grade 3 galaxies. This has resulted in some movement between bands based on my now greater experience and having a better idea of what I expect to see. My latest graded lists contain 38 grade 3 galaxies and 30 grade 2 galaxies (when combined this gives a list of the best galaxies to view when using military night vision technology combined with a low power eyepiece (using the TeleVue PVS-14 adapter). [Note that lower power eyepieces give the best spiral arm results as they “increase the effective focal ratio” of the telescope/night vision system which really helps increase the detail seen at the eyepiece.] As we are still in galaxy season 2020, now seemed a good time to re-publish my findings so others have the opportunity to observe some of these fantastic galaxies before they become “unavailable” for another 10 months… Grade 3 galaxies (the best of the best). M51 M61 M64 M65 M66 M81 M90 M91 M94 M95 M96 M99 M100 M101 M106 M109 NGC891 NGC2403 NGC2903 NGC3184 NGC3628 NGC3631 NGC3726 NGC3893 NGC3953 NGC4051 NGC4216 NGC4274 NGC4449 NGC4559 NGC4565 NGC4618 NGC4725 NGC5248 NGC5371 NGC5746 NGC5907 NGC6946 Grade 2 galaxies (good but the arms are not quite there…) M82 M88 M98 M104 NGC2537 NGC2768 NGC3294 NGC3344 NGC3373 NGC3596 NGC3646 NGC3675 NGC3718 NGC3729 NGC3813 NGC3938 NGC4013 NGC4214 NGC4293 NGC4389 NGC4490 NGC4517 NGC4535 NGC4625 NGC4762 NGC5005 NGC5364 NGC5383 NGC5775 NGC6015 Hopefully someone will find this useful information, next time they plan a galaxy observing session... Note that my dobsonian uses an Astrodevices Nexus unit which I control using Sky Safari. Here are my exported observing lists (which you can import into your Sky Safari app should you wish to do so?) Grade 3 Galaxies.skylist Grade 2 Galaxies.skylist 1. email them to your phone/ipad, 2. read the email on your mobile device and after clicking on the attachment, you should be offered the chance to “send to Sky Safari” by your email app… 3.Sky Safari will open and give a message “Observing List Created”. Clear Skies, Alan
  2. Celestron 9.25 at f6.3, SW EQ6R pro, Canon 550 D modded The galaxy group Hickson 44 in Leo. This is based on 29 x 240 s, plus bias and flats. Hickson 44 in Leo: There are some other galaxies near by, some of which are names in this overlay from Astrometry.net: Overlay from Astrometry, naming the other objects: The main ones are NGC 3190, NGC 3185, NGC 3187 and NGC 3193. NGC 3190 has a well defined dust lane. NGC 3187 is a barred spiral galaxy with two arms. NGC 3193 is an elliptical galaxy. The light captured by my camera last night left these galaxies just after the extinction event killed the dinosaurs on Earth. From APOD: Galaxies, like stars, frequently form groups. A group of galaxies is a system containing more than two galaxies but less than the tens or hundreds typically found in a cluster of galaxies. A most notable example is the Local Group of Galaxies, which houses over 30 galaxies including our Milky Way, Andromeda, and the Magellanic Clouds. Pictured above is nearby compact group Hickson 44. This group is located about 60 million light-years away toward the constellation of Leo. Also known as the NGC 3190 Group, Hickson 44 contains several bright spiral galaxies and one bright elliptical galaxy on the upper right. The bright source on the upper left is a foreground star. Many galaxies in Hickson 44 and other compact groups are either slowly merging or gravitationally pulling each other apart. Abell 1367 This image is based on 19 x 300 s , plus flats and bias. It shows a LOT of galaxies, in a grouping called Abell 1367. In this image you are looking at part of one of the biggest structures in the Universe, the Great Wall. Wikipedia: The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant (z = 0.022) in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, which is hundreds of millions light years long and is one of the largest known structures in the universe. The overlay from Astrometry gives some of the galaxies visible in the image.
  3. 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
  4. 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.

  5. 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
  6. 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...
  7. 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.
  8. 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.
  9. 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
  10. 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.

  11. 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?
  12. 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.
  13. 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?
  14. 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.
  15. 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.
  16. 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
  17. 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
  18. 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..

  19. 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
  20. Your essential Bank Holiday reading (aka the April 2018 Binocular Sky Newsletter) is ready. As well as the usual overview of DSOs, variable and double stars, this month we have: * Horizon Milky Way = culminating galaxies and globulars * A couple of Mira variables near maximum * The Moon just about co-operates with a quirky meteor shower So, if the sky is clear, grab your binocs (or small telescope) and use this guide to enjoy, and share with others, what the night sky freely offers us this month. To get your (free!) copy, or to subscribe (also free) and receive it monthly, please go to http://binocularsky.com and click on the 'Newsletter' tab.
  21. 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
  22. 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?
  23. 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
  24. 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.
  25. 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
