  1. hello this is my polarex 132F (((( https://youtu.be/7gPlOR__86w )))) POLAREX 132F video like New, this telescope pier has no scratches on it \(=,^)/ thank you, telescope from the 1950s
  2. To save time getting right to the point-Ive owned a celestron skyprodigy 90 and that scope alone made me feel more powerful than ever.Im planning on spending close to 2,000 on a new setup with a far larger aperture and although I love the cassegrain goto scopes from celestron and Meade,I’ve been wondering if my budget should go toward a custom dobsonian. My dream begins with landing a setup within that budget and choosing the right attachments to be able to study the moon up close and personal.If you can imagine it I’d like to be able to at least recognize a footprint if there is one.Im assuming this is possible while so many scopes can see so much further away like other planets and such. I’m more than grateful for any input that you’ve learned the hard way or any financial corners I can cut while still being true to the game. Thanks in advance.
  3. I’m a beginner, I started of with a 70mm focal length telescope with a 4mm lense. With this I am able to see the moon in fine detail however all other planets appear very small. Mars for example, I can see with me eyes and when I look through the telescope it is barely magnified. My question is; What telescope could I buy at a £300-400 budget to see all the planets in the solar system and perhaps even nebula from Andromeda.
  4. Hi all, I've just joined SGL and have a few queries about buying some equipment. I've had a look through quite a few posts but not found completely relevant information, but do point me in the right direction, as I'm sure these are very common queries! So I'm getting into astronomy, although I did own a Celestron First Scope a few years back. Although this was ok, I'm not keen on a table top scope anymore. To put things in context, I live on the outskirts of London, so still a fair amount of light pollution, but not terrible. I have a garden but pretty small (appprox 7x8 metres), with houses on two sides. However, I can get good views of Orion Nebula etc Having read around, I thought it best to get some binoculars i) because they are relatively lightweight (so I can take them to other parts of the country with better visibility) ii) as starting out, seems to make sense rather than having a large telescope I may use less Having tried a few binoculars I'm having slight difficulty telling much difference between them and wondering if this is a common problem?! I've tried the following: Olympus DPS I (10x50 & 8x40); Nikon Actions Ex (10x50 & 12x50); Nikon Aculon 7x50; Pentax SP WP 10x50; Celestron Skymaster 9x63. I really wanted to like the Action EX, Pentax and Skymaster, as prefer waterproof elements. Apart from magnification I've struggled to see much difference at night between all of these. I had big hopes for the Skymaster as it had noticeably richer colours during the day with large aperture, but comparing to others by picking out faint stars at night, they all seemed equally good/bad. In addition, I tried to see a difference in the contrast, but not much difference here either (maybe there would be no difference with light pollution). Unfortunately I sent the lower magnification back before testing some of the other and they did seem brighter from what I recall, but at the expense of detail. As you probably know, the variety in cost for these is large (£50-£200). I'm now wondering if my best bet is to just get a cheaper and lower magnification binocluar (Olympus 8x40) which I can hold by hand and a cheapish telescope (Celestron 130EQ) for the amount I could spend on the most expensive bins on the list? I've been a bit resistant to getting large bins, as was trying to avoid a tripod, but maybe I need to take the plunge, so any suggestions on these appreciated. Ideally I'd still have a slightly better binoculars if there are any recommendations out there, however I feel like I've pretty much exhausted the main options. I may still try the Skymaster 8x56. Any advice or suggestions appreciated on bins, telescopes, and also if there's a better way to test difference between products. Thanks and apologies for the long essay!
  5. Funny, the physical laws of reflection, refraction, scattering, diffraction, etc, are similar for sound waves and light waves, but the resemblance does not stop there. Listening to various car loudspeakers, I found the minimal diameter for an acceptable sound is 70mm, and that's also the smallest diameter for a satisfactory telescope in my view. 80mm grant a little more resolution in both, and 80mm is a very popular diameter in compact scopes or compact radios, at least the older ones. They make 90mm scopes to get some extra oomph, and the 90mm loudspeaker begins to issue more discernible bass, so much so I keep one from an old radio my father bought in the 70's, not knowing what I'll do with it but the bass, checked that when plugged to a guitar amp, is noticeable enough despite the size. Then the standard louspeaker size in non-toy stereos is 100mm, and the standard refractor size to get good resolution and power is also 100mm. There must be a reason if so many observers buy that many expensive 4-inch apos, but not nearly as many buy tighter apertures for comparable sums. Following the same progression, monitors in studios have 125mm to 130mm loudspeakers (that need to be complemented by a tweeter because the similarity cannot be total between light and sound), and these diameters are also the ones that provide deeper resolution on planets. 150mm approaches real power in telescopes, and 150mm is also the entry-level size for a guitar amp, like my 15 watt Fender Frontman, which does not lack bass despite its handbag format (WonderWoman's kinda big and heavy handbag). 200mm is quite enough for most observers, resolution-wise and power-wise, which happens to match the size of more serious amps. I have a modded Stagg 20w 200mm guitar amp and an Ampeg 20w 200mm bass amp, both are plenty large enough to deliver a full sound in their range. There is a reason if so many 8-inch Schmidt-Cassegrains and newtonians are in use everywhere! Then the 10-inch scopes are heavier, but not unbearably so, and the 10-inch loudspeakers also deliver the near-maximal power and resolution for an amp that remains not hard to carry around. 12-inch scopes deliver enough light and detail to satisfy most everyone; again, the equivalent 12-inch size amps give out enough frequency range and raw power to please the vast majority of players. Size and weight become an issue in both cases, but not enormously so. And lastly, the ultra-large 15" amps or 15" to 16" scopes start another league in power and resolution but they both become equally difficult to transport. Not quite apples and oranges in my opinion, does it seem like a coincidence to you?
  6. Hi everyone, I’m putting a shopping list together for an astrophotography setup and I could really do with a bit of advice on my options thus far. My aim is to photograph DSO’s (I’m really keen on imaging galaxies) I need a rig that is easy to set up and also portable as I plan to transport it to the darkest skies I have available to me. I’ve been shooting wide field astrophotography with a DSLR and a tripod for about 5 years now so I already own a modified Sony A7S and an unmodified Canon 5D Mk3, so I will start by shooting with these bodies. I'm still undecided on scope and mount, hence the list has options. My list so far: Telescope: Orion ED80 WIlliam Optics GT81 Explore Scientific 80 Essentials Mount: EQ6 HEQ5 Finder Scope and CCD for Guiding: Orion Mini 50mm Guidescope Meade DSI Colour I intend on using PHD for guiding. I also need other accessories such as field flatteners etc, so any advice on 'the extras' would also be greatly appreciated. I don't expect to get hubble-esque images from this rig! I would like to go down the refractor route, but other than M31 which is, of course, rather large, are these telescopes going to be any good for galaxies? It is one of the reasons I am leaning towards the Orion ED80 as the scope for that extra 120mm of focal length as all the scopes listed are f/6. I'm also leaning towards the EQ6 for the mount but any other suggestions are more than welcome. Thanks is advance!

I would love for someone to buy job lot at a price of £3500.00 , which would include many items I have not listed , power supply , many adapters, leads ect ect If you have any questions please feel free to ask Thanks for looking
  8. James Berry was my ancestor and he was, amongst other things, ia clockmaker and optical instrument maker including telescopes. I would be interested to find out if anybody out there has or knows about any euipment he made. Please PM me with information, thanks
  9. of all the kinds of telescopes, is there any one kind that just flat out is better or do all different kinds do different things better? I'm on the market now to buy my third scope, so i want to see if there is a "best" design, and if not, what kind of scope suits my needs. i don't do astrophotography yet, but i want to at some point. i have a honking big minivan so portability isn't big deal, and anyway my mak is very portable. i have a pretty good budget, i can spend up to $700 on this although i would like to keep it under $600 if i can. i would love specific recommendations, but i also would love just general ideas.
