I was thinking about getting a telescope myself, what would you guys consider a good buy? I am not looking for anything too fancy, at least to start with, but I do not want some wimpy little scope either.

My purchase range is ~$200, of course anything less is great.

Here is a couple I have seen, but I do not know what to look for exactly:

http://www.opticsplanet.net/barska-675x900mm-starwatcher-reflector-telescope-ae10758.html

http://www.opticsplanet.net/meade-114-eq-a-model-45-f-8-equatorial-telescope-04055.html

http://www.opticsplanet.net/sky-watcher-sw-80ars-mm-telescope.html



I am currently just interested in looking at the planets/moons
It is 2 Cents or .02 Dollars...NOT .02 Cents!

For $200 you can get some pretty decent scopes for novice/beginers.
I'd either go with the Meade or the Barksa. It may just be my opinion, but I'd say the Meade. The Meade scope you have chosen also has a few reviews when the Barska doesn't. Always read some of the reviews before you buy anything.

The specs say the meade is a 4.5 inch. The scope I had before(http://www.opticsplanet.net/meade-ds-2130ats-lnt-goto-autostar-reflector-telescope-20135.html) (It's also on sale now!) the one I do now is just .5 inches larger and has a go-to mount, was perfect for looking at the moon and planets. Though a low powered eyepiece you can easily see the moons of Jupiter and some of the cloud belts. It's also really good at looking at looking at brighter deep sky objects like the Orion Nebula or Andromeda Galaxy. These would do just as well.

Do some more research on these scopes and read the customer reviews. You may find a better one in your price range.

Nice Pics Jack, thanks for posting. :aok

Ive been looking into getting one myself, I know this is going to sound newbish, but if i get a decent telescope, will i be able to literally see the planet? Not just a bright dot in the sky, but the full planet itself? For example, if i get a decent ( 200 to $400 scope) could i see say.....the rings on Saturn etc?

Honestly, save a bit and get a schmidt-casselgrein type scope. Its good for everything, very compact (easy to store/move), light and best of all... needs no fieldwork besides wiping the lens (like a refractor).

Yes. You should be able to see the rings of Saturn with a really small scope and the right eyepiece, but it would be hard to see because of the size and glare. $400 dollar range is good.

By size and range you mean that Id be able to see the planet, and that the glare of the planet would make the rings hard to see? So seeing say...Jupiter, i might be able to see the storms and such on the surface?

Yes, you will be able to see it. I mean the size of the planet in a small scope will be small.  That plus the glare might make it a little difficult. Larger scopes not only make the view larger, but also it has the ability to gather more light, so you'll be able to see more detail. The bigger the scope, the larger the view/the more detail that is shown.

The scope won't be powerful enough to see the actual storms on Jupiter(Mine isn't even able to see that). The reason is that the sun's glare off it would be to bright, but with the right eyepiece you'd be able to make out the cloud bands. Unless you had a filter which cuts down on light glare. That might bring out some more detail.

When looking though a telescope, you don't see color. For example, if you were to look at the Orion Nebula, which is one of the brightest deep space objects in the night sky, you wouldn't see the colors you do in photographs. Instead, you'd see a greyish blob. The reason for this is because the light from that object takes awhile to actually get to earth and our eyes aren't sensitive enough to pick up the color. The Sun's light takes about 8 minutes to reach earth. If you were to see a star randomly erupt into a supernova while looking up at the sky, that would have taken place maybe thousands of years ago, but the light from that explosion is just reaching earth/our eyes. Most deep space objects aren't really even visible to the naked eye, because their light doesn't reach earth fast enough and our eyes aren't sensitive enough to see them. This is where a camera comes into play. The reason a camera captures what it does is because it's film/ccd chip is more sensitive to the light and is able to gather it together much better than a human eye can.

So, the planets would basically look greyish in color, too, but because they are close enough to earth, you might be able to see some color. If you looked at Mars (would just appear as a red dot in a small scope) then you could see the reddish hue of it, but not a lot of detail because of the glare.

a good rule is the bigger the mirror the better the scope, I had a 4" mirror I could see saturns rings, but they looked like one solid ring.

Yes, because the bigger mirror is able to absorb more of the light, which brings out more detail in the object which you are viewing.

Don't know what I did, but the I got it to work. The Go-To is still a little off, but tracking is working 100% better!

Glad to here you're "on track"!

Nice job on the images.  I hope you don't mind, but its a compulsion I have to try and enhance peoples images.  Its just how I practice when I don't have images of my own to work on. ;)

This is what I was working toward:



It looks to me there might have been lots of good data in there that could be enhanced but the image you posted looks like it was bit-clipped or heavily compressed.


Jpg mangles image data.  Its a lossy compression.  I always prefer png myself.  That wasn't captured in jpg or 8bit was it?  If you still had the original 16bit data I'd like to try on that if your interested.  What are you imaging with btw?

Any way,  keep up the good work.  You're shaming me into getting out the cameras again.  I think I might fiddle with some solar stuff.

Clear Skies,
Wab

Look's pretty good.

I'm using a Canon Digital Rebel XSI. The images it gives me are in .jpg format, but I have it set so it gives me both the .jpg format and the original RAW(.CR2) file.
Is there a way to attach a file in a PM?

You might try putting it up on DRopbox.

You mean it " Gathers " light.

One more thing that hasn't been mentioned on this thread:

Light pollution......check your area on a dark sky chart to see if your in a dark area.
