  1. Hello everyone! I'm new here. So my question or questions may sound kinda ignorant. The answers may be a little obvious. I love this site and have read so many comments and learned so much! Anyway, I have a Canon 60D camera with live-view. I have a Tasco reflector with D=114mm F=900mm(this maybe a little small?). I will be using a T-ring/adapter and with this I hope to capture many decent photos. But for the eclipse, do need a special filter for the scope or the camera or both? If so, could you give suggestions where to get this? Thanks to everyone for any help!
  2. I'm looking for a Vixen FL80(s) with a GP mount or even without. Like here http://scopeviews.co.uk/VixenFL80S.htm Thanks for any advice about possible clues where to get one!
  3. When the barrel of my meridian 675x4.5" reflector telescope falls below around 30 degrees it just falls down, and will only come back up above 35 degrees. This makes it impossible to observe objects towards the horizon. Any help would be much appreciated.
  4. Hi everyone, I recently got myself a GSO 6" f/4 astrograph, but seems like the secondary mirror was quite off. I then tried collimation using Astro Baby's tutorials, and others around the net. I've had a few Nets during the past 20 years, but this one seems to be a bit of a pain to get right. The secondary holder is a bit stiff. Anyone here done any mods for the scope and have reasonably good performance? I'be attached an image with Mire De Collimation circles. Image shows the reflection of primary, followed by the edge of secondary and followed by the grey card placed behind the secondary, which ends with the focuser tube. Any help will be appreciated. Edit: If I were to move the secondary towards 2'o'clock position, could it solve the problem?
  5. So I have recently just gotten the Saxon 200mm reflecting telescope, and with it I received an erecting eyepeice to view terestial objects. Problem is, people are saying to insert into threads and I've tried to do that but it doesn't fit? How do I correctly place the erecting eyepiece onto the telescope? Please help! Images of regular eyepeice for space objects (28mm) and other parts included to help.
  6. 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
  7. 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
  8. 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
  9. 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.
  11. 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
  12. Looks like my Lipo project so far may be working good, ran a trial last night with a 3200Mah 3 cell Lipo from my RC airplane, the battery is an 11.1V nominal charge (uncharged) but charges up to 12.6V (4.2V per cell fully charged). All Lipo batteries display nominal charge capacity, which can be misleading because when charged, they jump up in voltage past displayed voltage. I wanted to see how long that went for before using one of my larger 5000Mah batts, didn’t take much more than $5 for a 2.5mm connector with 6ft cable included and a Deans connector on other end for the battery. I have a small voltage meter we RC guys use to monitor battery levels per cell and combined voltage, meter just keeps displaying levels constantly then emits a buzz when it drops to pre programmed level. The loud buzz I muffled to a pitiful hum by dropping some hot glue over the little speaker holes, last thing I need is an 80 decibel buzz at 2am in my yard. I set buzz for 3.5V per cell which is lowest you want to drain a Lipo per cell, after slewing around manually more times than I can remember I still had enough juice to slew around for another hour if i wanted, I was mimicking a nights slewing around and I think after I slewed around on both axis simultaneously on and off for 40 min I pretty much covered a nights worth. the test will be in the field, if this battery doesn’t cut it I’m sure the 5000Mah will do the trick. I was watching for any shenanigans from the scope as the level dropped but nothing, no glitches or twitching of the controller display, all remained solid. UPDATE: The next morning i turned on the scope (without recharging battery) and again spent the better part of an hour until i was just bored slewing the scope around, i was afraid to burn out a motor with constant back and forth slewing with a short pause of course. i am now convinced that this 3200mah battery not much bigger than the average candy bar will last a whole night out and more! fantastic to know that when i drag the scope out for short periods locally (won't need heat strip those times) that this battery will be fine. i was dreading having to take my 50Lb deep cycle marine battery every time id like to go for a short local 2hr outreach session, on those long drive dark sky all night sessions yes i will need heat and my marine battery but those a few compared to short local sessions. I can now fit my power supply into my pocket and that is just GOLD!!
  13. 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
  14. 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!
  15. 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
  16. 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.
  17. 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
  18. 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".
  19. 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 .................

  20. 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.

  22. 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.
  23. 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!
  24. 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....
  25. 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!
