  1. I Did IT! I bought my first telescope! A Celestron Nexstar 4SE I am sure that there are a million reasons why I should have bought something else but it's too late now! I am delighted! Bought on E-bay for around 1/2 price I now have the Telescope + 9mm and 25mm eyepieces, a 2x (ken) Barlow, a focal reducer(??) and a T-mount (eyepiece and camera port versions) After a 250 mile round trip to pick it up I pointed it at the moon with the 25mm. Well WOW!! I stuck my DSLR on an took a pic! WOW! (probably not very good to you lot but for me! Wow!) A couple of nights later I set it up again using the Align function and took a tour - saw Mars and Venus, Polaris and a couple of other interesting looking fuzzy things. Of course there is an unimaginable amount to learn, but I am hooked! Cheers MZ
  2. I would like to know what type of telescope should I buy to begin with. I'm not a professional astronomer, but i'd like to get into the subject further. Even started to get involved in chemistry and physics. lol.. please help. thanks
  3. William John Macdonnell was one of the leading amateur astronomers in late 19th century Australia. Since he was a child, Macdonnell was fascinated by the the stars and went on to own several good refractor telescopes, two of which have survived. In the 1880s Macdonnell was branch manager of the Bank of New South Wales at Port Macquarie and constructed an observatory in the backyard of the bank! Around 1885 he bought a 6" Grubb refractor which was imported from Dublin and cost 250 pounds. By the 1890s however Australia was in severe economic recession; Macdonnell was forced to sell his telescope and left the bank. He found new work as a financial consultant in Sydney with a salary of 50 pounds per year! The Grubb refractor changed hands several times, at one point being used by another important amateur, E H Beattie, until it was put in storage in 1921. Fast forward to 2005 when the telescope was finally bought by the National Museum of Australia and restored to its original condition. The link below shows a video of Hermann Wehner demonsrating how the telescope was set up and used: http://www.nma.gov.au/av/portmacquarie/the-southern-sky/a-night-of-observing/ It appears that Macdonnell's fortunes slowly recovered and in retirement he was able to purchase a 4.75 inch refractor made by James Parkes and Son of Birmingham in November 1907. Macdonnell died in 1910 and the telescope was subsequently bought by Sydney industrailist Ernest Wunderlich who later donated it to the New South Wales branch of the British Astronomical Association. It is now preserved by the Sydney City Skywatchers. Macdonnell with his Parkes telescope
  4. I have looked on other topics and threads to find an answer to my problem, but alas I have been unable to. My apologies if I am reposting a topic previously covered. Since I have recieved my scope (see signature) back in the summer of 2012, I haven't really given much thought to its collimation. However, recently with the cloudy nights and boredom, my mind has drifted to fine-tuning my scope and buying stuff I probably don't need . I have read Astro Babys Collimation Guide and it looks like I'm gonna need a Cheshire and a Cap, not a problem. My problem is the Primary Mirrors centre spot, mention in the guide. My wee scope, as far as I can see does not have one, and I'm pretty sure I need one. My questions are as follows: 1) Do I need to remove my primary to put one on? 2) How do I remove my primary if I need to? 3) What do I use to add a centre spot? Thanks for taking the time to read.

    In my search for Comets at the moment, I had a night outside on a clear evening last week. I cannot wait until Comet ISON makes it's way round.
  6. Hi everybody! My family want to go to Australia in the next couple of years, and I really want to take advantage of this opportunity to see the southern sky, and I want to take a scope. However, I can't possibly take my 150p, it's much too heavy, so I'll need another scope. I've been thinking about the SkyWatcher Skymax 127 goto, for several reasons: 1. It's light (approx 11kg) 2. It's compact 3. It would make a good secondary scope in the future, because it's good for planets, and nearly as large as my 150p in aperture But I've been wondering, is 11kg too heavy? I mean, it will be a 3 week holiday, so there will be a lot of clothes to take up weight. And if it is, what could I take that's lighter? Thanks for reading David
  7. Hi Guys, I wondered if it's possible to attach a mirrorless camera (that is a camera that is not able to remove it's lens) to a telescope. Is there an attachment or a camera holder? Luminous Thank you, in advance
  8. Hi, I am doing an end of degree project on variable stars due next thursday and London's weather does not allow finish it. I was wondering if someone would do me the favour of observing the pulsating variable star V0460 Andromeda http://variablestars.net/stars/460/ in the Johnson R filter, for a period of 1 hour and 50 minutes? please? Thanks so much!
  9. Hi all, I saw recently this telescope on amazon : here It's cheap .. cheaper than the binoculars in fact! Would it be a good telescope? what can possibly go wrong ? https://www.amazon.de/700-76-Teleskop-Pack-Smartphone-Adapter/dp/B01I3BWICA/ref=sr_1_1?s=ce-de&ie=UTF8&qid=1527263025&sr=1-1&keywords=700-76+Teleskop+Big+Pack Link edited
  10. Decided to put cooling fans on my newtonians a 200pds and a 130pds ,used a 120mm on the 200 and a 80mm on the 130pds ,i used, Be Quite silent Wings2 fans they use rifle bearings and are so quite German made, i did the 200 first and was impressed with this make so ordered the same make for the 130 pds it comes with a lead with four wires but only needed neg ang pos so snipped other two out , made a disc from plastic and cut out around collimation screws on primary then used velcro to attach to OTA fitted a 2.1mm dc socket on to the disc then bought a usb lead to 2.1mm barrel though i may fit another 2.1mm socket on my power box and use 12v either way it works ,i used a dimmer on the 200pds but it doesnt need it and wouldn't use it again but its fitted now so will leave in place.
  11. Hi I am very new to this and looking to buy my first telescope I dint have a very big budget and looking at a secondhand scope at first. I have come across this on eBay and was wondering what people think of it A Saxon 130 reflector telescope on an EQ2 mount and has motor drive it comes with 1.5x erecting eyepiece and a Super 10mm eyepiece Thanks in advance Ste
  12. Its about time!! i made the 3hr round trip to my scope shop (after a tough days work) but all well worth it, i could not wait till the weekend when i'd have plenty of time to go early and avoid rush hour traffic, be well rested and awake, that makes no sense at all lol. I was far too giddy to wait for the weekend, anyway she's here and she's beautiful!, i will no doubt be tossing that horrible 28mm eyepiece it comes with and replacing the finder scope with a spare telrad i have. Now i just need a clear night and a couple of hours for equilibrium and we'll see what this little gem can do! it sure feels and looks like a quality piece of gear i must say, that beautiful corrector just screams "i mean business".
  13. The Great Barred Spiral Galaxy ( NGC 1365 ) in the constellation Fornax edit: new version with new long exposure data ( 52 x 240sec ) and better dark subtraction / dithering to remove streaks in the noise and amp glow. This also allowed for a greater stretch revealing more faint data in the galaxy and small faint fuzzies in the image .. The Great Barred Spiral Galaxy ( NGC 1365 ) in Fornax ( please click / tap to see larger ) and below I have added a 100% crop of new version: ........ original image: NGC 1365 ( please click / tap on image to see larger ) ............... The Great Barred Spiral Galaxy ( NGC 1365 ) in the Constellation Fornax Below the equator, not seen from much of the Northern hemisphere, NGC 1365 passes very nearly directly overhead an observer situated near Cape Town, as Sir John Herschel was in November of 1837, or near Sydney, as I was, almost exactly 180 years later, when I photographed this “remarkable nebula” that is numbered 2552 in his book of observations from the Cape. Not called a “nebula” now, of course, this striking object is one of the nearest and most studied examples of a barred spiral ( SB ) galaxy that also has an active galactic nuclei resulting in its designation as a Seyfert galaxy. At around 60 M light years from Earth, NGC 1365 is still seen to occupy a relatively large area ( 12 by 6 arc minutes ) due to its great size; at some 200,000 light years or so across, NGC 1365 is nearly twice as wide as the Milky Way and considerably wider than both the Sculptor and Andromeda galaxies. This High Dynamic Range ( HDR ) image is built up from multiple exposures ranging from 4 to 120 seconds with the aim of capturing the faint detail in the spiral arms of the galaxy whilst also retaining colour in the brightest star ( the orange-red 7th magnitude giant, HD 22425 ). Also, scattered throughout the image, and somewhat more difficult to see, are numerous and far more distant galaxies with apparent magnitudes of 16 to 18 or greater. Mike O'Day .................

  14. The Rosette Nebula and Cluster ( NGC 2237 and 2244 ) in the constellation Monoceros edit: updated 30th Dec with improved colour balance and slightly increased brightness ... ...... original: ( please click / tap on image to see larger and sharper ) Still a work-in-progress really... with only 10 x 4min exposures for the main 'lights' before the clouds came over. I will try to add some more data when the moon has gone I am still experimenting with how to get the best out of the D7500. With the very warm nights ( low to mid 20s all night ) the 'warm pixels' are very noticeable so I reverted to my old practice of in-camera dark subtraction.

  16. Hi, I am a beginner I am wondering what telescope should I buy. It will be my second one, my first one was about £50 and I could see the moon very well with it. Things I am looking for in my next telescope. 1) Not more than £240 2) Gives clear view of Jupiter, Mars, Moon, Saturn Thank you.
  17. Hello all! My father lives in Istanbul and he has the Gskyer AZ70700 Refractor Telescope. He has been really enjoying it as you can see from the photos I've uploaded in the Amazon review I've left for this item (Btw, I've just realized that this review is now the most helpful/liked review on this item which is cool): https://www.amazon.com/gp/customer-reviews/R35LBDSUABUUAU/ My father is OBSESSED with looking at the moon's craters and he had this telescope for almost a year now and he probably never skipped a day at looking at the moon as long as the moon was visible. I've made the post below on this forum before asking for suggestions on what upgraded equipments I should buy for his telescope: And after the suggestions and more research, I've bought these items: 1) Celestron 8-24mm Zoom Eyepiece (1.25") 2) Celestron 90° Star Diagonal (1.25") 3) SVBONY 1.25" Barlow Lens 2x Multi Coated T Adapter 4) Orion 05598 1.25-Inch 25 Percent Transmission Moon Filter (Black) Now basically, my father's only wish in this life is to be able to zoom at the moon more and see the craters of the moon more clearly while being zoomed more. Right now, when he uses the 2x Adapter with 8mm eyepiece, things get blurry but he keeps trying to zoom more some nights and tells me that he is hoping one day it won't look as blurry on that amount of zoom I showed him a youtube video of the moon's craters zoomed in with a better telescope once and he was basically shocked and almost didn't believe me that that was possible with better telescopes though I am not sure how bigger/better/expensive those telescopes would be. Now my father had an open heart surgery recently but he is OK now and I really want him to experience using a better telescope while he can and me being a good son, I want to buy him a better telescope now as I have a bit extra money to spend. I bought the telescope he is using now for 130$ (btw, this telescope had 5 star average reviews on Amazon at the time of my purchase which is why I bought it but I wish I knew about this forum before and asked you guys before buying that one although my father still loved the telescope a lot so I don't have many regrets about it). I was wondering if there are better budget telescopes that are around 180-300$ that can be at least a bit better than his current telescope when looking at the moon's craters while being zoomed more with better/clearer visuals. Btw, because of the light pollution in Istanbul Turkey, only the Moon, Saturn and some big stars are visible in the sky but my father only cares about the Moon craters anyway. It's also important for me that the telescope I'll buy will support 1.25" eyepiece that my father has. After I've read many Top 10 articles online, the Celestron PowerSeeker 127EQ seems like a good budget option for me and I hear that because it has 1000 mm Focal Length, it's a good option for looking at the moon? I wouldn't know much about that thought which is why I wanted to get you guy's opinion on this. I've also seen that this telescope is being sold in Turkish websites (such as n11, hepsiburada, gittigidiyor etc.) which would mean I wouldn't pay anything for shipment to Istanbul and that he would have the option to return it in 14 days with a full refund if he doesn't like it. However, if you guys think that this telescope wouldn't really differ much from the telescope he has now when it comes to looking at moon's craters zoomed in, or that there are better telescopes than this 127EQ that is not too much more expensive than 127EQ but better at looking at moon's craters zoomed in and still beginner/mid-level friendly when it comes to looking at the moon, then please let me know! I'd really appreciate any input on this before I make my purchase. Thank you in advance!
  18. Hi all, For the first time in my life i have bought a telescope(celestron astromaster 130eq)..So iam very intrested in seeing my favourite orion nebulae , How can i get a closer image of it like shown in many pictures..Is it possible to see very closer from this telescope and how the color comes? is the color of nebulae is fake or real? What eyepiece can i use to see the distant deepsky objects very close and clearly... Thank u....
  19. Hi everyone, Nice to meet you all this is my first time posting here, im currently looking into buying my first telescope but i am having a lot of trouble choosing which one to buy. Ive veiwed many makes and models such as Celestrons,Orions etc but just cannot choose, as i am a complete beginner i dont really know what to look for and everytime i think i have found a good telescope i delve into reviews from around the web to find they may not be so good. I was wondering if anyone on here could help me out with this please maybe some suggestions? I'm hoping to find a good quality telescope for planetary veiwing and veiwing celestial bodies and also maybe some astrophotography, my budget is around the £400 mark any help will be most appreciated thank you!
  20. Cross post from other forums, so sorry if somebody already it) Good day, dear astronomers. Read the forums for some time, but now i'm in need of some advices. My only experience in AP is from reading many forums and specification of different hardware, so i can count me as noob) And only year and a half observing stars, moon and sun with my 130mm newton). First of all, wanted to say that I live in Ukraine (Odessa to be precise) and one of my friends will be returning here for holidays from NY. So I decided to ask him to buy me some equipment there because its near to impossible to get something decent hardware here in Ukraine (we only have some celestrons, arsenals (gso) and entry-level sky-watchers and other entry level observing equipment (mostly dobsonians and newtons). So the point is that I need to be very precise with my decision on what parts exactly to buy, cause I wont be able to return them (in near future) if something wrong with them, or if I miss some crucial small details. Also wanted to mention that besides AP, I want to use it sometimes for observing moon, sun and large DSOs... 1) On telescope I think I decided already - it will be either this or this - highpointscientific.com GTF81 or this highpointscientific.com GT81. First one comes with built-in flattener (but I don't undertstand one thing - description says its f\5.9, but in specification it states f\6.6). The second one comes with separate field flattener\reducer which takes it to f\4.7). I don't really know what should I buy between those two. Both those comes with mounting Rings and carry handle. First I wanted to take orion Newton astrograph, but i decided against it, because some people said that its bad idea to take reflector as first AP setup, so big thanks to those people!). 2) Mount - here where I really need an advice cause there are plenty of them... I read countless forums, and amount of information confuses me very much. Its also very hard to decide cause nowhere here i can see them and i can only rely on forums or youtube videos. SO after several weeks of lurking i found several mounts. a) Vixen Sphinx SX2 - there are a lot of vixen mounts out there, so its hard for me to choose. iOptron iEQ45 Pro - same here, many iOptron mounts, very different opinions on them as i read on the forums. c) Orion Atlas Pro - another suggestion i found on the forums. d) and the last one which i find the most appealing(!) and also many good reviews about this mount - Losmandy GM-8 - many good reviews and also i found some pretty photos out there in astrobin with this mount. But i want to be sure here.. i assume that WO-FTG will fit onto gm8, right? or i will need something in between(sorry for dumb question) and about the mount itself - in optcorp link it shows that it comes with a tripod, which is around 200$ (so obviously mount alone is about 200 less). Do i need to order mount separately and order better tripod for it? Another thing that concerns me - should i get GeminiGOTO system for this mount? it adds a lot of money, tho i don't sure if i need it... And how does that digital drive on the mount operates? Can anybody give me a link or tutorial for losmandy mounts setup for AP without GOTO system and how does it work with PC? 3) Guide scope - WO Guide scope, tho it comes with rings, which are already exist in WO GTF or GT models of scopes. Maybe there are better ones there, so i can be open for suggestions. 4) Camera - here I'm confused also, but found some good reviews on new ZWO 1600 camers (with cooling). Color and monochrome ones. I cant decide which one to take, but thinking about monochrome one, cause there is a good chance that i can find filters here. If you had some experience with other cameras in same price range, i will be glad to hear which ones)). Also it would be cool if you can advice me what company should i take filter from? I know about astronomic, baader and thousand oaks. And how exactly do they connect to telescope? I know that's between camera and telescope itself, but how they differ in connection types? I can just plug them? (sorry again for dumb question) 5) Diagonal for observing - found some models (also read that mirror is better then prism, but also price changes too). From Vixen there is Vixen 2" Dieletric Coated Diagonal 50.8mm and more pricy one is from AP - mirror (i assume later one is mirror, so that's why its so expensive). 6) + some more eyepieces for observing, but i think i can find some for moon and maybe sun. 7) And solar filter.. I'm not familiar with filters for refractors(. I have one filter for my Newton right now, but it works like a cap. Is it the the same for refractors? or they can be like special filter for eyepiece? I think that's the only questions i wanted to ask for now, but i'm sure there will be a lot more stuff to ask) Sorry for the wall of text, i hope i could express my thoughts correctly, my English as you can see still sucks). Thanks a lot in advance and for your answers) PS also important thing that i don't wanna miss some cruicial things, that i couldn't order later here. I'm afraid that i might miss some cable, or plate, or something while ordering)
  21. Hi guys, i own an 8 inch newtonian telescope with a focal length of 1200mm and a focalratio of f/6. My big concern is the focal length though. can this newtonian be used for astrophotography or do i need to buy an astrograph so i can start with imaging. Or is there anything else i can do to reduce the focal length or of my current newtonian so i can start with imaging...???
  22. Hey folks, I know this might seem like a stupid question but I am about to buy myself my first telescope and I am confused by the telescope itself being much shorter then the stated focal length (The focal length is supposedly 1000mm, but the telescope itself is like 40cm). I've spent hours on the internet trying to find out as much about telescopes as I could but I didn't find any page that would answer this question. Thanks in advance
  23. Hey guys I'm an aspiring beginner astronomer and observer, and I recently inherited my grandfather's old telescope. It is a Meade Quartz with the LX Pulse drive. Only one problem, he left me with no instructions. I learned about the Barlow lens, and how it magnifies the normal eyepiece, the only problem is I have no idea how to attach it. The hole where I normally fit an eyepiece is far too large for it to fit. The size of the hole can fit a 26mm lens. Is it because I have brands mixing and it can only fit a Meade Barlow? I appreciate the help.

  25. Hi all, As the title says, is it possible to make my own triplet apochromatic refractor? I've made my own Newtonian reflector before, and I've heard of people making their achromatic refractor, but what are the difficulties of making a triplet apochromatic refractor? Thanks! Fishie
