I can't believe the sheer "observational ignorance" of some people. Unless you're willing to do some WORK to LEARN what's possible, you might as well pack it in. Good thing is, someone (who hopefully knows something) will pay you almost 90% of what you spent on your scope when you sell it used! So you aren't out any real money. Then you can go pursue a hobby you can understand, like video games. -Rich Another compassionate conservative being helpful. Clear Skies, Uncle Bob |

What am I doing wrong? I look at Saturn and it is no more than 1/4"
in size, not at all what was described to me. I think I could have spent $100 on a scope and seen this much. Do I have the wrong eyepieces? What do I need to buy to see a planet fill up my field of view? And what do I need to see a constellation in its entirety in my field of view? Please help me..I have a 6 year old who is dying to see the solar system up close. I'm amazed at the negativity you're getting from some of the respondents. Anyway... The unfortunate fact is that Saturn is incredibly far away and it would take a magnification of perhaps 500x or more to bring it to a size that most beginning observers would consider comfortably large. However, a sharp image at that magnification requires an excellent 10" or larger telescope in combination with extremely stable atmospheric conditions. Even those of us with large telescopes are usually limited to 300x or less, due to the atmosphere. This is a huge variable. Two months ago I observed Saturn through my 14.5" and had a difficult time making out Cassini's Division. Then two weeks ago Saturn was the best I'd ever seen it, sharp at 398x and I'd have gone higher if I'd had tracking. With your 5" scope you'll need to deal with an image that's smaller than you'd initially like, but rest assured that there's still plenty to see there. With practice you'll adapt and begin to appreciate what you're seeing. Have patience and look for the following: Cassini's Division Shading variations in the B ring The faint C ring The Equatorial Belt The dusky polar region Shadow of the planet on the rings Several moons Cheers, Ritesh |

wrote in message oups.com... Bigger is not always better. That's right, it's not. Why buy a larger scope if it will get less use than what he has? Of all the scopes I have, from an 8" SCT to the Orion 80mm ST, the 80mm gets the most use. It's grab and go. Big scopes are a pain to setup, as I was warned in this group 10 years ago when I was shopping for the 8". As predicted I favor the smaller, lighter scopes. The 8" has its place, and it gets use, but not often. That's why I suggested that he research first before jumping into the hobby. My sense is though that he has already had the ETX too long and is now stuck with it. However, that doesn't mean he can't use it, but he will have to find material appropriate for that size of telescope. The "sketch" drawings submitted by amateurs I mentioned previously can still be of tremendous help in that regard. I do recall many such sketches being made with scopes in the 3-6" range. I think the scope he has is the right size for the aspiring amateur who's main interest is planetary views. If he add's a pair of good binoculars for sweeping the sky he'll be set. I agree, especially with the point about binoculars. EVERY amateur should start out with binoculars. I myself used a pair of Focal (that's right- Kmart!) 20x60's for at least 7 years before getting my first scope. There's no better way to learn the sky, IMO. And with the tremendous cost savings these days of the Synta binoculars, he can pick up a pair with great aperture at a great price. However, if he just gets a pair of 10x50's that would be all he would need right now. I would add a good low power EP, 32mm perhaps. It's my most used EP with my 8" SCT, but wider field views are my preference. For many DSO's, wide field is a must. He'll benefit from a low power eyepiece. John Andy |

"Sketcher" wrote in message ... Hi Johnny! That telescope you have is capable of showing you quite a bit of this universe. Many of the early astronomers would have been amazed by such a telescope! OK, so Saturn isn't as large as you were expecting it to be; but could you see the ring? With a bit of patience, practice and good seeing conditions you will see more in that tiny planetary image. At times you'll be able to see 1 or more of Saturn's moons. There's the Cassini Division -- a dark gap separating the A and B rings. There's the shadow of the planet on the rings. Even some subtle detail on the disk of the planet is within reach of your telescope. Be sure to check out the moon! The full moon can be interesting; but you'll see *far* more detail on the moon when it isn't full. From night to night as the moon goes through its phases you'll see different craters, mountains, etc. The moon is a wonderful target for backyard observing sessions. When you're at the telescope relax, take a deep breath, erase expectations from your mind, look into the eyepiece and see what you can see. Study that view. Take your time -- and you'll see more. Concentrate on what you *can* see -- not on what you once thought you should see. Books from a library or bookstore are highly recommended. Look for books geared toward the backyard observer. Such books will give you a lot of valuable information. When looking through an eyepiece I like the philosophy: "Expect nothing. Be happy with anything!" Astronomy can be a wonderful hobby -- you just have to give it a chance! P.S. The naked eye is the best instrument for constellation study. Different telescopes have different strengths and weaknesses. Your telescope is as good as any for getting your feet wet in this hobby. Feel free to comment on anything you see in this newsgroup and feel free to ask questions. Everyone here once had a first telescope, etc. Sketcher To sketch is to see.

Discard, return, or sell the scope and find another hobby. You are too
expectant to deserve a telescope. Try baseball or another sport. Who knows, your son may end up being playing pro if you start now. Good luck, Ace "Johnny Lightning" wrote in message ... Help!

I won't argue against the obvious benefits of increased aperture, but isn't it the focal length of the telescope that defines the magnification of a given EP? Ian Robelot wrote: Yes, but the image will look a lot brighter in the larger apertures. It's a tradeoff... the image will look larger and brighter in a larger aperture scope, but will be much more influenced by seeing conditions than a scope of smaller aperture. I think that's most often why people observing with the smaller apertures feel much more satisfied with the views because they are a lot more stable. The virtue of smaller aperture scopes w/turbulent overhead is sometimes true here. For my aging eyes (47 going on 70), I find that I prefer at least a 130mm of clear aperture for Jupiter and about 150mm for Saturn (more aperture is preferable). That said, I still have fun using even smaller scopes on these objects. |
