  1. Hi, I have a skywatcher 200p dob and was hoping someone would be able to recommend an eyepiece with a wide field of view that would help finding objects and observing larger objects like the Pleiades. I have had a look at an explore scientific 30mm with 82° FOV, but was unsure if it would be good with my scope. Thanks Katie

  3. Hi, I want to place a CCD camera where the secondary mirror is, remove the sec. mirror completely. It,s a home made F5 14 inch. Do I have to use a coma corrector or/and a field flattener? Can I use a Barlow with a field flattener or coma corrector, can I use eye piece projection with a field flattener or coma corrector? Many thanks, Markus
  4. hello... ^_=)/ I have a vintage telescope polarex Do telescope 100% by hand .... my question is can i do stars shooting ... with vintage camera OR digital camera have old camera leica R3 like to use it ????? thanks this is my blue star STAR KIT 1.tif
  5. Hello, I am trying to control my Heq5 pro via SynScan (ver 3.10) with Stellarium (on MS Win10, 64 bit). I got the proper cable and adapter to connect to the usb port (via an adaptor for the RS-232). In Stellarium I follow the instructions to add a telescope / configure / add new telescope but when I get at the level of the device settings (see image), the field to select the port is blank and cannot be edited. I know I am using port : Port_#0001.Hub_#0004 (from checking the device manager) on my laptop. I tried installing Ascom but I still can't find the port there neither. I tried using a different port #3 but same issue. Anyone knows a work around the issue? Thank you \\
  6. Hi to all you members on SGL. I am a novice with 3 months experience with a SW200P dob, having started initially with a pair of Oregon 15 x 70 Bins on a tripod mount. I have referenced some good books and spent some time with Stellarium and I am encouraged by my new learnt ability to navigate the night sky with the 200p. I have connected my Nikon D600 (24mp full frame) DSLR to the scope and produced some satisfying photos of the moon, however I am interested in imaging some DSO's. ( I have caught the bug with no cure in sight!) I intend to get a tracking mount such as a SW HEQ5 Pro Synscan, but for now would like to purchase a wide field refractor and produce some wide field imaging with a basic mount, I understand that subs of around 30 sec can be produced with mediocre results initially until I get a better mount. Also it would be nice to have a grab and go scope which is more convenient than the big DOB. Also this would give me some images to experiment with the software such as DSS and Registax 6. So, I have been researching three achromatic telescopes, The Skywatcher ST80 and ST102 (both come with kit mounts ranging from AZ3 to EQ1 and the Bresser Messier AR-102/600 (which looks stylish and has the Hex focus) However, despite spending somewhere in the region of 4-5 hours so far researching for reviews on the BM102, nothing has been forthcoming>? I am aware of the issues of CA with these small tube Achromats, however the plan is to Purchase one of the three now, save for the HEQ5 mount, then at a later stage use the scope purchased now as a guide scope and but a better APO doublet or triplet scope for the main tube. So, having laid the table so to speak, which of the three would you advice and why please, I have been told by two companies stocking the BM102/600 that mechanically it is far superior to the two Skywatchers, but I am concerned that I cannot find ANY reviews on this OTA for its optical quality ?. I am aware that Synta make a few of these 80 and 100mm scopes for different suppliers but I am let to believe that the BM is a separate manufacturer. Any advice or better still hearing from someone who owns the Bresser Messier AR-102/600 would be amazing, so thank you for reading this long post and thank you in advance of your reply. Regards Graham Side note:- I have a VERY heavy duty pan tilt Manfrotto tripod which I previously used to support my Sinar 5x4 Large format bellows camera so its very steady and has a pan tilt head already fitted, I intend to mount the new scope on this as an AZ to begin with.
  7. Hi, I am completely new to this but am wanting to do some stargazing and astrophotography. i have a great interest particularly in the deep sky and am wondering what kind of telescope i should get in order to mainly view the deep sky but also one that if i wanted to i could view planets etc. there are low levels of light pollution in my area and i have a pretty good budget (around 1k) wanting a quality telescope that i will still own in years to come as i am wanting to go on to study this. i am currently looking at reflectors but was wondering if anyone thought that i was looking at the wrong type of telescope based on my preferences. if anyone has any recommendations i would love to hear them as i am not yet sure about well trusted brands etc. also for the astrophotographers out there what do you believe is an essentials kit for a beginner. Thanks
  8. Hi all, Whenever i took pictures attached to my telescope i get a big white flare in the middle..am using celestron astromaster 130eq with nikon d3200...i hv attached a sample image..please tell me y this happens?
  9. Hello guys, I may have found exactly the forum I need here I would be really glad if you could help me a bit please : I love stargazing on the mountain next to home (low light pollution), but now I want to level up. I mean, I'd like to use a device that is better than my eye to see the night sky. The problem is I am quite lost between telescopes, lenses, reflectors, refractors, and hybrids devices etc. So here I am, coming for your advice that will be, I am sure, of great help. Here's my question : what device is best suited for my use ? I'd like to see constellations and close deep sky like big galaxies (andromeda M31 for example). I am aware that refractor lenses are less bright than reflexion telescopes but I'm not certain which one to buy. > The main purpose would be a looking through device, but ideally if I can plug my Canon DSLR it would be fantastic. What are best brands for an amateur ? I prefer to pay more but once than cheap but twice and have a budget of around 250-300 € (if one is a bit above but really effective I can go a higher). Thank you a lot in advance for your time and advice ! Golfox2
  10. Hey everyone ! I am new to this site , don't know how to properly use it , but hope someone will help me As the topic says , I am trying to buy my first telescope , and am quite excited for it. I have been reading wuite a lot about astronomy , so I know most of the basics , but have many many unanswered questions ... xD I was originally looking for a scope for viewing the planets , but well , after learning more , I thought that maybe a scope that can show only planets will eventually get a BIT boring , and will not be used much (although I still admire the planets and still will want to observe them). Just a quick info on me : I live in a city , have no place to go / or car to transport my scope to a darker place , live in a building , hope to observe from the rooftop. My ONLY CONCERN about this is that from my balcony I can see Vega at night , and as depressing as it may sound , nothing more .It may be because there are buildings covering my view (I at least hope so that's the case) or light pollution , although the place I live is in the orange to red zone in many light pollution maps. So originally I stumbled upon the Orion Starseeker IV 80mm GoTo refractor. http://www.telescope.com/Telescopes/GoTo-Computerized-Telescopes/Orion-StarSeeker-IV-80mm-GoTo-Refractor-Telescope/c/1/sc/15/p/113919.uts Thought it was good for the GoTo and stuff , but after doing some research , got concerned about the sturdyness of the mount.Some said it was too shaky (I have almost constant winds of about 10mph at night here) . Plus after some while I discovered DeepSpace and got even more interested in it than the planets . So I started to seek for reflectors. After a while I discarded Dobsonians as an option , cause I do want to do astrophotography ( just amateur , not gonna spend money on expensive DSLR s or sth) . And maybe in the future I will want to do some more serious astrophotography , so it will be very sad , if I have to change the scope later , if I want to... So after doing some research I am currently watching these scopes . 1. Orion 9827 AstroView 6 Equatorial Reflector Telescope . https://www.amazon.com/dp/B0000XMSR0/ref=psdc_499154_t1_B01N2HJBQC 2. SkyWatcher Explorer-150P EQ3-2 Reflector. https://www.firstlightoptics.com/reflectors/skywatcher-explorer-150p-eq3-2.html The only downside of these is that they're not GoTo (The second one has an option , but it's out of my price range) , but I think an additional RA motor drive will do the thing. At lease if I will be able to find anything in my sky ... That's it ! If you own/have used any of these scopes tell me more about them ! What you like/dont like etc. ANY GENERAL ADVICE IS APPERCIATED . Thanks !
  11. Hi there, I'd like to get my husband a telescope for his birthday. We're beginners and have a young daughter. We live in Nairobi and go camping a lot and would like something portable that we can take into the bush with us (so fairly robust). I've looked at ratings online and many recommended the Celestron 21035 70mm travel scope, but it got quite mixed reviews. Am less concerned about astrophotography than just looking at the sky. Was also looking at Celestron NexStar 130 but also has a lot of mixed reviews including bad electronics. I'm willing to spend up to $400. Since we live in Kenya, its hard to ship faulty scopes back and forth for repair. Does anyone have any particular recommendations? Want large aperture, robust, portable. Probably refractor. Any recommendations most welcome, thanks.
  12. Hello. So i am very new to the world of astronomy and i just want to stargaze. I would like a telescope to look at the Moon in decent detail and maybe some other planets too and some stars too. I type this to get some help. Below i have multiple options for telescopes. I am on a strict budget, under $50 and i want a telescope that just does the job. i do not need any extreme scope just one that'll do the things mentioned above. Here are the options: http://www.ebay.co.uk/itm/360-x-50mm-Reflective-Monocular-Astronomical-Telescope-Space-Spot-Scope-Tripod/132194688993?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D2%26asc%3D43781%26meid%3D9616727f6af84b67ad88a06df4fed9bb%26pid%3D100005%26rk%3D2%26rkt%3D6%26sd%3D152515267398 http://www.ebay.co.uk/itm/Performance-700-76-Reflector-Astronomical-Telescope-NEW-UK-FAST-DELIVERY-/191464648175?hash=item2c942eadef:g:6gEAAOSwBahVaDII http://www.ebay.co.uk/itm/900-60-Reflector-Astronomical-Newtonian-Performance-Telescope-60x900mm-Silver-/262966529588?hash=item3d3a06ce34:g:QRMAAOSwurZZNgwR Which one of those will be the most suitable for me and which one would you recommend. BTW, i live in Birmingham, UK.
  13. I could use some expert advice on purchasing my first telescope for astrophotography. I have been using my Canon 5DMIII and an Astrotrac and have decided to upgrade to a tracking EQ mount and telescope. At first to image with my Canon and later CCD. Currently I am considering three scopes: Sky-Watcher ProED (100mm doublet ED APO 900mm FL (f/9)), Meade Series 6000 (80mm Triplet ED APO 480mm FL (f/6)), Explore Scientific (102mm Triplet ED APO 714mm FL (f/7). Any opinions on which would be best for astrophotography of galaxies and nebula? Are there others that are better that I should consider? I have not selected a mount yet but something like the NEQ6. Thanks, Lloyd Linnell
  14. Good morning everyone, Just to start out, a little about me: I'm US Navy stationed in Sicily, Italy, originally from lower Alabama. I've always been an Astronomy geek, pointing out the stars and planets to friends at night....nothing beats a calm, windless, clean night out in the middle of the ocean. Other than what I've picked up over the years sky watching and reading, I've recently finished up my second semester of Astronomy so I have a decent understanding of the sky....but I know bare minimum about telescopes. I never owned my own telescope and it's been a while since I've looked through one. I did some research and almost bought an entry model celestron a few years bac, but didn't. I like to consider myself beyond beginner, so I'm looking for an intermediate level scope. I've done several telescope finders and seen several reviews. On a budget of under $1,000, but would rather stay closer to $500. I want to see the moon yes, but more interested in the planets and deep sky objects. I will be traveling with it...by traveling, I mean driving about an hour or more to get to a nice dark field. With that I've eliminated a dob, as an option. I'm looking for something that will fit in my car, and a grab n' go/no hassle. My main question is does a newtonion/reflector type require much maintenance? like if I pack it up and drive to spot am I going to be fumbling with it in the dark, trying to get a clear picture? I really want something no-hassle and spend more time viewing than aligning. The reflectors get more aperture for the money over refraction type. Astrophotography is possible, once I get more comfortable and can afford it, ill get a mount, but other than that a simple iPhone snap will suffice. That brings me to my next point, I'd like to explore and would rather spend the money for a good view, than the motorized mounts. Are the motorized mounts really worth it? I also planned on getting a eye-piece/filter kit. So, I've narrowed it down to the Celestron Omni XLT 120mm- the entire Omni line keeps popping up best reviewed/high rated lists; The Orion SkyView Pro 8". Like I said I also plan on getting a filter/eyepiece kit. Any other options or are these good?: no-hassle, decent deep sky/good planet view, $500-$1000 budget (including eye-piece kit), fit in a car. It's my first telescope, so I want the best bang for the buck, not a beginner scope. I'm an adept learner so I'm not scared off by non-computerized mounts (and I want to learn to use without it). Thank you for the help!
  15. Hi I have a Sky-Watcher telescope, model AC 120/600 Startravel BD AZ-3 that I want to use to take photographies. This one: http://www.astroshop.eu/skywatcher-telescope-ac-120-600-startravel-bd-az-3/p,16710 I have an "old"(2009 model) Nikon D3100 camera and a t-ring, but the thing is that my camera won't read the t-ring. I read online that it's too old to be compatible with a t-ring. So I wondered if anyone knows about any camera models I can use? I'm thinking about getting a new camera because of this and I would like some recommendations. Which cameras do you know are able to "read" a t-ring? I would prefer the cheapest models Thank you for your time
  16. I have acquired an old 1960s Newtonian telescope which I am reconditioning as part of my STEM Ambassador volunteer work with a school in Bury St Edmunds. It's currently I my garden but when it's in a fit enough state it will move to the school grounds and hopefully be the seed of a new Astronomy Club in the area. I've already started doing after-school solar system and rocket making/launching sessions, so hopefully the scope will grow the club into something accessible to many children in the area. The reason for the post is I'd like to discover more about the provenance of the scope, so I wondered if any SGL members would be able to help? The primary mirror is 300mm diameter, the secondary elliptical mirror is 63mm (minor dia) by 90mm (major dia). Estimated focal length 1560mm, so f/5.2-ish. The tube is 1.6metres from the back of the primary box to the front of the tube; the front tube is 390mm diameter. It stands on a massive concrete block, angled at 52 degrees, which takes 4 men to lift... So far I have stripped it down, cleaned the bearings and regreased them so it is useable. I successfully collimated it with a Cheshire - first light showed not much coma, so happy with that for now. The focuser is rather tired and it needs at least a RA drive to make it easy to use, and the primary needs recoating. I believe it originally came from Norwich Uni, but I have no details. If anyone recognises this magnificent instrument or knows anything about it, please let me know - it'd be great to share this with the school as excitement mounts! Current state, in need of a lick of paint Original state (old photo)

  18. Hey I am new to this forum, For now I am going to be heading towards (amateur astronomy hobbyist) till I finish my education and hopefully become an astronomer! I am really interested in astronomy,but sadly I miss the equipment ,My equipment for now is : Strong binoculars My eyes A kids toy telescope well, I really am most fascinated by galaxies and nebulae, so i am waiting (since 8 months) that my mum gets money and buys me a real telescope! So does anyone know any good cheap (100$-300$) telescopes which can see galaxies? If anyone would give me a link to buy it I would really appreciate it!
  19. I am new to using telescopes, and this is my first. I have assembled the telescope and can view an image on a nearby island (in the day) and the moon (at night). I can attach the camera however I just see a black image. I would love to be able to attach my camera to the telescope and capture what I am seeing! Not sure if I need to attach an adapter or fit a specific lens? Any help would be much appreciated! Many Thanks Alice
  20. Hi there! (Before reading, my English may not be the best, but I hope you'll understand what I mean and say) I'm currently looking for a telescope that will blow my mind (in a weird way). I've been a "fan" of the night sky since I was a little kid, now I'm 21 years old and I want to give the skies a try. So, the telescop I've been thinking about buying is the Sky-Watcher Explorer-150P(EQ3-2) F/750. To me it seems like a decent telescope for a beginner, but I have my questions to those who are experienced with telescopes and those of you who maybe own their own Sky Watcher Expl. 150P. Questions: 1. Is this a good beginners telescope? Please explain why it is, and why it might not be. 2. What will I be able to view with it? 3. Is this a telescope I can use to take pictures? If so, how can this be done? (Using a laptop or a digital camera?...or both?) 4. Is it difficult to take it with you and to operate it? 5. If you could please rate it from 1-5 (for beginners), where would you put it? Those are the questions I have right now, I might come back with more later. I'm hoping for friendly and informative replies that can help me decide. It's already pretty late here in Norway, so I'll be going to bed now, but I hope some of you can answer me within the next few days. Here's a link to a website I might be buying from: http://www.stjarnhusetonline.se/prod/telescopes/sky-watcher/newtonianreflectors/explorer150.html Have a great night. Much love from Norway.
  21. Hi, Bought celestron astromaster 13eq b4 2 days this is my first ever telescope..today for nearly 2 hrs i tried to point to the mars..but i couldn't point..i can see with naked eyes but could not find in telescope..it was very frustrating with eye pain,head pain...can u tell how to locate a star or anything with the s/w..what the numbers are in the eq mount??how to use the s/w and point to that particular object with those numbers??? please help..i saw only moon clearly... Thanks...
  22. Hi All, So we were down at my parent's at the weekend and I've been working on my ongoing project to refurbish my old telescope so my Dad can use it - a Tal M from 1994 (!). Here's a picture of this vintage 'scope: As you can see everything is fine except for the fact that one of the tube rings has shattered in a fall. I need to replace the second tube ring but have no idea how to go about it. The rings are cast iron, and here is a picture of the broken ring for reference: What I want to do is either: Mend the broken tube ring Replace the broken tube ring Find some other way of attaching the telescope to the mount. It's an 88mm / 3.5'' reflector. Really nice 'scope - we gave it a whirl to check the optics and got it pointed at Saturn and it still shows a lovely clear picture. My Dad was careful to keep the tube somewhere the dust wouldn't get to it. Which of the above options would be the best solution to fixing this fine telescope for my old Dad?! DD
  23. Hi. I am looking at buying a new scope. I am VERY limited for time. With a 60hour a week job and three kids, I do not have time for a full time hobby but i really want to do some of my own viewing but with as limited input and as much output as possible. I go to my local astro club but I want my own scope that will go in the boot of the car that I can take out and set up easily and see whats out there without too much trouble or having to spend lots of time learning. I know this sounds like lazyness but it really is time that limits me. I have recently found the Celestron Skyprodigy 6inch which initially sounded like the absolute perfect option for me. I have since read a few negative comments on here about the auto align being a 'gimmick' and a waste of money but it seems it would allow me to drive out somewhere and get going straight away and have it find objects for me with its auto tour funtions, after it has auto aligned. The other option would be the nexstar8 but I have had no experience with a goto before and do not know how to manually align and how long it takes and then how to find the objects. Any advice would be greatly appreciated. Are the sky prodigy really no good? Or do you think they might actually have a use for people such as myself? Thank you Richard
  24. Hi folks, for all of you interested in Radio Astronomy, you might be interested on this. In the Island of Sardinia is being built a pretty nice Radio Telescope, 64 metres of diameter supporting frequencies between 0,3 to 100 GHZ. The project is financed by the Autonomous Region of Sardinia and the Italian Space Agency. It will be employed for Radioastronomy, Geodynamics and other space-related matters. Its management is shared between Cagliari Observatory, the Institute of Radioastronomy of Bologna, the ASI and others. I think the whole thing is stil not fully operative (the image below is a Live Feed updated every 10 minutes, look at the sky ), but should you spend any of your holidays in Sardinia, you are allowed to visit the site.
