Hi all, im new to astronomy
![]() store telescopes before... long time ago- and enjoyed looking mainly at the moon. I had a few questions to ask well- anyone that will answer them. first off- with all UNDER 10,000 dollar telescopes just see stars as dots of light? I guess this might be a stupid question- but personally I was underwehlmed looking through telescopes at our local photography stores Mars Night last week. Maybe the telescopes didnt have much power- but stars were just dots of light. Dont get me wrong- i find it amazing thinking about how long ago the light reaching my eye was sent out- but im curious if thats all of stars you see with non- observatory power scopes. 2. I love looking at the moon. Its just my favorite object Ive seen thus far through a scope- the detail amazes me. Ive seen it through expensive scopes ( went to an observatory in hawaii when i was there for vacation- up in the mountains- saw all sorts of objects through all of these telescopes- simply amazing detail) My goal is to get a scope that gives me the best detail of the moon for the price- and have it be able to take photos ![]() got the camera aspect covered- but scope wise i dont know what id need. I enjoyed looking at mars too- and still do- but we've had bad weather lately. With the above in mind- can anyone recommend a good telescope- and does anyone have any pictures that might show me the detail i would see in stars- mars- and of the moon through that recommended scope? i look online and see all sorts of pictures - great detail- beautiful colors- etc of stars and of the moon and such but I have no idea if it was a huge obsevetory that took them- or just a backyard astronomer- so id like to get a feel for the detail im getting. Yes I know the number one rule is try before you buy- and im trying to contact some astronomy clubs in my area to do just that ![]() second opinion never hurts-- right? thanks in advance |

In fact there have only been a couple of observations made of the very closest stars, with the very largest scopes, that have any measurable angle at all. Even the Here's a link to an image by the Hubble Space Telescope of the massive Red Giant star Betelgeuse, which is relatively close, and one of the very few stars that can be resolved to more than a pinpoint. http://hubblesite.org/newscenter/archive/1996/04/ As you can see, only with the most powerful telescopes and the closest, most massive stars, direct imaging of stellar disks becomes a possibility.

Dont get me wrong- i find it amazing thinking about how long ago the light reaching my eye was sent out- but im curious if thats all of stars you see with non- observatory power scopes. Stars are at vast distances. As the other poster said some of the near by giant stars like Betelguese can and have been resolved as a disk, by large Telescopes. Ground based ones have to use special techniques to overcome air turbulence to obtain the necessary resolution, whereas the Hubble Space Telescope can do it directly. The theoretical resolution of a telescope is related only to the diameter of the aperture. See: http://www.licha.de/AstroWeb/article...php3?iHowTo=16 2. I love looking at the moon.

With the above in mind- can anyone recommend a good telescope- and does anyone have any pictures that might show me the detail i would see in stars- mars- and of the moon through that recommended scope? I personally drool over these: http://www.globaldialog.com/~obsessiontscp/OBHP.html and http://www.starmastertelescopes.com/ They can been adapted to photography by throwing them on an equatorial platform. Another option would be a Meade or Celestron Schmidt Cassegrain with all the electronic gee gaws and a wedge to change them to equatorial mode i look online and see all sorts of pictures - great detail- beautiful colors- etc of stars and of the moon and such but I have no idea if it was a huge obsevetory that took them- or just a backyard astronomer- so id like to get a feel for the detail im getting. Photography can and does show much more than you can see visually through a Telescope. Amateurs often take astrophoto's that rival what you see from professionals. If you get a copy of "Sky & Telescope" you will see that each month they have a section where they publish amateur astrophoto's. They also give details of the scope and camera used etc. For wide field photography, the apochromatic refractors are hard to beat but they are a lot of buck for the bang so to speak. Rgds Llanzlan.

Hmm is it normal to have to disassemble a scope to get it outside iwth these
bigger scopes? If so maybe ill try the recommended one :P "Michael Keating" wrote in message .. .
