      Robert that is correct. Good sky grade binoculars will give you vivid views of Orion Nebula, the Moon, Andromeda, full constellations, you can tell the planets are blobs-not stars (about it) but with steady arms or a camera tripod you can see the four largest moons of Jupiter. Much less skill and patience required. Some telephoto cameras do quite well with planets, but you are looking at a digital video image, not direct optics. I carry binoculars whenever i take my telescope out (about three nights a week but I live on a mountain 10 miles from the middle of nowhere in a national forest)
      Cheap refractors ($50-100) are however how children should start. Keeps them from believing they are being tricked by Masons at NASA and PhotoShop into believing the planets are actually round objects millions upon millions of km/miles away.

My great uncle and aunt who build there own telescopes and buy their van based on if it can fit there biggest telescope when they travel to their club locations (awesome!) had me start out with just a good pair of binoculars. That way I could see the moon and many other planets to a certain degree and learn where everything was. If I was to of bought a big telescope that cost much more and really didn’t catch the “fever” for astronomy so to speak like I did the telescope would of gone to waste.

It was a, maybe a 3' reflector and my binocs had a much more enjoyable image. I soon saved my money and purchased a Tasco 9te2 refractor. A good little scope.

Vinyl really sucks in some ways, but it's also very easy for DJ's to manipulate, which is why it was popular for so long in the electronic music scene. Most electronic music before 2005 or so was only available on vinyl. If you've been DJing for more than 10 years, you have a vinyl collection, and not really by choice.

      I do teach historic astronomy to kids and adults, using graduations of cheap scopes that are optically equivalent to those used between 1500 and 1750AD. Cheaper refractors and AZ mount long tube reflectors (usually 114x900mm and 60x400mm) for the Newton variants.
      You'll be amazed what you can see in a very dark deep country winter night. They do a marvelous image of Orion, Venus phases, Jupiter and the kids can see Saturn is Saturn. The simple cheap scopes are also easier for the novice to control.

    Hah! LOL I have the _exact_ same $5 piece of junk telescope! I bought it exactly under the same conditions: it was a drugstore, it was MSRP $20 but discounted 50% (don't think I got to pay only $5 though), and the review is very accurate in all aspects!
    In the end, it's indeed pretty much a worthless piece of equipment, because it has lots of magnification you can't really use; and the mount is so flimsy your breath makes it oscillate, thus adjusting _anything_ throws _everything_ off. Plus, there's chromatic aberration in the image like it was made by a game developer from 2013, and (the aperture being too small) the image is too _dark_ to really see anything you can't see with the naked eye (so lots of stuff); and having relatively highly magnified dark invisible stuff isn't of much use.
    Unfortunately, getting it to sharp focus is also quite the challenge, with the gossamer web mount and flimsy telescope body, so in the end, the image can't really be brought to actual focus, although sometimes part of the image will seem focused, but not all of it (the lenses in it are nothing good, the eyepiece one is plastic). That noticeably blurry picture that was shown is pretty much a good indication of what you can get it to do, except in person it's a bit worse, because it never stops moving altogether, so on top of the blurriness and aberration, it's always wobbling-it can get frustrating.
    In the end, this telescope is a mild scam: Putting it near checkout lines, highly discounted, at ridiculously low prices, in venues in which you have no business buying optical equipment (like drugstores), and also targeting people who themselves have no business buying optical equipment, but might want to surprise a niece, or a grandson-all that is part of the con-it's a bit like the "speakers in a van" con (a scam that, incredibly, just won't die), in which the trickster drives around in a van, approaching people in traffic lights and offering supposedly high-end speakers (in reality, total crap) at impossibly low prices. Considering I bought this telescope almost ten years ago (and it was in the U.S.), and they're still making and selling it today, the 4-9 bucks-learning fee that you pay is enough to sustain the enterprise. 😂

    Actually, far from being highly dispersive, fluorite crystal is prized for its extremely low dispersion (overall), in addition to its unusual partial dispersion characteristics (different from that of glass, and higher only between certain wavelengths) that together with appropriate mating glass elements allows for much greater correction of chromatic aberration than without fluorite.
    In fact, it is possible to achieve near-apochromatic performance using only one fluorite element and one ideally-matched glass element, which makes for fairly affordable and compact "fluorite doublet" refractors. Their affordability is helped by the development of new optical glasses (e.g. O'Hara FPL-53) that have very nearly the same properties as fluorite but are only a fraction of the cost. These glasses generally have fluorite as one ingredient, but are otherwise glass rather than crystal.

    Scott, could you please make a video explaining all the numbers you just used? What do the length and diameter of a telescope actually do? What is apature? Why is there a difference in how big certain lenses are? Why does magnification not mean anything? You are the perfect person to answer these questions! I'd really love a video with some diagrams and equations!

    • @kilovian353

      Aperture is the diameter of the primary lens of the telescope. Logically, the larger that diameter is, the more light enters the telescope at once, giving better details and brighter images. Therefore, aperture matters much more than simply the magnification you are viewing an object at. The focal length of a telescope is the distance between the primary lens and its focal point (the light is refracted in a conical shape, eventually intersecting at the focal point), and the magnification is calculated by dividing the focal length of the eyepiece you are using into the focal length of the telescope.

      @oldfrend 6 ปีที่แล้ว +2

      magnification only matters if your telescope is high quality enough to actually see details, otherwise you'll just get a blurry mess no matter how good you are at focusing. there's a rule for effective magnification vs aperture but i forgot what it is, but generally the wider the aperture the greater its angular resolution and the finer details it can make out. i have a 130mm reflector and at best i can make out a few bands on jupiter. can kinda see the red spot even with the image magnified to fill up the lens.

    • @fred_derf
      @fred_derf 6 ปีที่แล้ว +1

      Apature is the diameter of the objective lens (the big one at the front) or the primary mirror (depending on the design of the telescope) and directly determines how much light the telescope can gather -- the bigger the better, the more light that is gathered the more detail you can see.
      The focal length is the distance between the objective lens (or primary mirror) and the focal plane (the point where the image is focused at). The focal length determines the "zoom" level of the telescope (or more precisely the angular size of the resulting image). Camera lenses are sold based on their focal length, I have for example a 100 mm - 300 mm zoom lens and that determines the angular size of the resulting image.
      Imagine taking a camera and setting it up to take a picture of a wall, with one lens it will image a 10' by 10' area of the wall, then you change to a lens with a longer focal length and now you can only image a 4' by 4' area of wall. Magnification is a product of the focal length.
      The moon, for example, has an angular resolution of about 31 arc-minutes. If you look at it with a telescope that has a 2 degree field of view the moon will only take up a quarter of the width of the image (or 1/16th of the whole image). If you use a telescope with a longer focal length that has a 1/2 degree field of view the moon would take up the whole image.
      With a telescope, you can use different eye pieces to change the magnification, but all they do is limit the amount of the image gathered by the telescope that you can see -- it's analogous to using digital zoom in a camera. It doesn't show you any more detail, it just makes the detail bigger.
      So to go back to the earlier example of a telescope with a 2 degree field of view, rather than changing to a telescope with a longer focal length you can just change the eyepiece so that the moon fills the whole frame, but it would so by only showing 1/16th of the image gathered by the telescope.
      BTW: When I changed from using 35 mm film to a digital camera body the image sensor in my digital camera is smaller than 35 mm film which has effectively increased the magnification of my lenses, but it's done so in the same manner as changing the eye piece in a telescope. For my camera the effect is minimal and the benefits of it being a digital camera far outweighs the minor loss of image quality.
      So, if you want to be able to see more detail (i.e. have a better image, not just a bigger one) you need to get a telescope with a bigger objective lens (primary mirror) so that it gathers more light and if you want to focus on a smaller piece of space you need a telescope with a longer focal length. See, magnification isn't a factor.

    • @buggsy5
      @buggsy5 6 ปีที่แล้ว +1

      You should be able to do far better than that. That is a 5" aperature and you should be able to see Cassini's Division under good seeing conditions and a good ring tilt.
      The basic rule is that more than 20x/inch aperture is seldom useful and 20x only when the atmosphere is quite steady. Average seeing is more like 5x to 12x. So, with your scope, look for magnifications in the range of 25x to 60x. Go higher if the conditions are steady.
      You didn't mention the focal length, but many reflectors of such small diameter are f/8 or f/10. That would put your focal length somewhere in the 1000 to 1300 mm range.
      That means a 25 mm eyepiece will give you somewhere around 40x to 52x. You might be able to use a 15 mm eyepiece occasionally.
      There is an exception to the rule when you are just trying to split double stars. There you are not looking for detail, so a lot of blur is acceptable. I have used as much as 50x on such occasions, but the stars are pretty dim.

It even had a mount that you clipped onto the edge of your car window so you could use your car as a tripod of sorts. Plus the image went through a prism and was non-reversed.

    • @k.h.1587
      @k.h.1587 4 ปีที่แล้ว

      It looks like an Orion skyview pro 100. Not sure if they still sell those. 100mm f6 achromat, will have considerable chromatic abberation on bright objects, and there are filters that help with that at the expense of varying degrees of yellow tint to the image, the most expensive option, the baader semi apo having a slight yellow green tint but not as strong as basic minis violet fringe killers. A basic light yellow filter also helps a bit as well. The best being a Stack of fringe killer and neodymium filter, which the semi apo combines in one filter.
      The SVP mount is big enough for visual use with an 8" Newtonian, and I actually used mine to image with an 8" f4 and 80mm f11 refractor as guide scope back in the day. I had purchased the SVP127 which is also no longer sold as a package, which was a 5" maksutov Cassegrain f12. I got the 80mm f11 as a celestron nexstar 80gtl 2004 $149 Costco special , and purchased a baader bracket dovetail adapter, surplus tasco starguide 4 tripod (same as nexstar 4/5 tripod), and made me a decent etx125 substitute with the 127 on the nexstar mount.
      Then I bought the 8"f4 optical tube from Hardin (no longer selling consumer scopes, these were made by GSO in Taiwan), a guide scope rings set from Orion to use the 80mm as a guide scope, and a 12mm plossl XY adjustable reticle eye piece (so you can move the reticle around to line up with the best guide star) and I used that set up for film astrophotography for a while. This was 2004/2005. It was the maximum for the mount, but I had no problems, and also later on bought a 2" cg5 tripod used which improved stability, and adapted my smaller (astroview/omni cg4) class Hardin star hoc mount to work with the SVP tripod (1.75"), which made it the equivalent to the omni cg4 (which was not out yet).
      Having friends in an observing group where the smallest big scope was 12" and we had an 18" and sometimes a 28" out there, I quickly realized that hearing all the oohs and ahhs and calling out if they would still be on it in 3-4 minutes when my exposure was done, made me realize that autoguiding and your own dob as a visual scope was really the way to go.
      Also because when I finally got my DSLR (Nikon d50 2006) I discovered that digital is less forgiving of guide errors than film.
      This was back in the days of the Orion catalog, and before Orion sold any goto scopes other than the intelliscope push to system, which was also available as an add on to the skyview pro.
      The 100f6 was also available on the smaller astroview mount which is adequate for it, and the 127 mak is still sold that way
      From my greater experience learned since then, and 5 years (part of it as top dog) sales at opt 2006-2011 I would personally suggest the celestron omni 102 f9.8 scope if one was to get a 4" refractor as their main scope. F9.8 has much less false color, while f6 excells for wide field (extreme wide field in the realm of 15-25x binoculars or wider with the widest 2" eps), there is the color I talked about earlier, which is far reduced at f9.8 (f10 basically)
      Orion (these at least) and celestron scopes are both made by synta, the omni mount is the same as the astroview BUT it comes with a 1.75" steel tube tripod that the bigger SVP mount comes with, so it is very stable. The series also includes a 120 mm f8.3 refractor which is at the limit for that mount but still useable, a 150mm f5 reflector which a buddy of mine did some decent astrophotography with when he hacked the dual axis drive controller for autoguider capability. Also a fine visual scope (I had bicoastal pair of Hardin 6-5 equivalents for a while) .
      There was, maybe still is, a 6" 150mm f5 short tube refractor in the series as well, but I would only suggest that be used as a low power wide field deep space scope due to excessive false color and mount loading making it not a good high power instrument. Refractors are heavier than reflectors when they get that big.
      The omni 102 long tube refractor is excellent for all uses in its class, excelling in planetary and lunar, and with 2" eyepieces can still show some wide field views, and in fact, refractors offer the best contrast on open star clusters even in the city they can be seen better than other designs that have central obstructions. And I. Dark skies the clusters are amazing.
      And one of the best views of m101 (a large faint spiral galaxy) was in a 4" refractor in dark skies. The extra contrast helped bring the spirals out
      The scope is also in the under $500 range.
      I did use my star hoc on 1.75 tripod a couple times with the 8"f4 visually and it worked well, and recently put a c8 on my current astroview on a 2" tripod and it was rock solid, so I know that omni mount is no slouch. c8 is lighter than 8" newtonians and much shorter, so I wouldn't suggest putting a longer than f4 8" on one, for that size (f5 f6) you want to go with a CG5/SVP.

    Flourite (CaF2) lens elements are *not dispersive* (13:25) - rather the opposite - they exhibit low dispersion (variation in refractive index versus frequency) and are therefore used for certain elements in the optical path in order to improve overall chromatic abberation. As they are more expensive they are only used judiciously.
    Coating improves contrast - but is not as necessary for single element designs.
    Baffling also improves contrast by reducing veiling glare.

It has a sturdy tripod, it comes with an equatorial mount, it is a reflector so it has a large aperture allowing it to collect a lot of light which gives you nice detail, and it has a nice focal length of around 660 mm so you can get good magnification. You can get great views of the moon, Jupiter and it’s moons, and Saturns rings and even a few of its moons on a clear night. This telescope is wonderful out of the box, but I found it works especially well with an Orion moon filter and a 3.6 mm eyepiece on Amazon (total cost about $30). I have had incredible closeups of the moon with extraordinary detail with that combination, and I was able to make out the bands and spot on Jupiter. I have to say this is a great telescope for beginners, and for a good price too. I definitely recommend this telescope! Hope this helps!

      HashtagCatsInSpace never bought a filter for anything don’t know why. Otherwise not many complaints great for beginners may want to consider upgrading the mount and lenses.

    I had that exact same telescope when I was a child, in the 1985... Some things never change ! I barely was able to see saturn's rings with it, and it was super blurry.

    Just reassembled the achromatic doublet in my ancient telestar. I took it apart when I was a kid and didn't put it back together cleanly or correctly. I also had it stored outside and dirt-daubers had built nests in the tube. It's gunna be stored inside from now on.
