Welcome to singastro, innerpeace
I do hope you meant astronomy and not astrology because this is an astronomy forum, not the latter. Do check out our faqs on general knowledge as well as places to stargaze. [smilie=cool.gif]

Welcome InnerPeace!

Im a beginner too! Learning as I go along! This forum is helpful and lots of good advice you can take with you as you read both new and old post and questions. Surf around and even though it may not be related to what your looking for, it will surely give you more knowledge as you go deeper into stargazing! This and the world wide web....lots to learn and see. Especially with the very often cloudy singapore skies!...[smilie=hate.gif]
But even when it's mildly cloudy, I still set up my scope and experiment to understand my toys more. Mostly to just have fun trying!

With fun nothing is dull!
Stay in touch and take care!

hi am a newbie too!


can we observe the orion nebulae and andromeda galaxy with a 4 inch tele?


like see the gas clouds of the orion nebulae and the spiral shape of andromeda?


btw how does light pollution occur?


isit the light from the stars are diffused by the light from street lamps?


so even with a large telescope we wont be able to see the milky way in sg due to light pollution?

A. Yes

Q.btw how does light pollution occur?

A. We all din off our lights when not using. The streets light..

Q. isit the light from the stars are diffused by the light from street lamps?

A. Its so bad that we can "light up" a new moon

Q. so even with a large telescope we wont be able to see the milky way in sg due to light pollution?

A. Thats why we org trips overseas just to see that!

Orion Nebula is the easiest nebula you can observe in Singapore. You can see it as a hazy patch of light using naked eye and can see the shape with basically telescope of any size.

Andromeda galaxy can be seen as a hazy patch using naked eye if the sky is very clear and you are at a dark site in Singapore. Using a 4" telescope, you won't be able to see spiral arms in Singapore... you usually only see the core of the galaxy.
astronoob wrote:btw how does light pollution occur?
Light pollution is caused by air particles reflecting the light from those unshielded lighting... such as building lighting and IMHO, the road lighting is basically the main source of light pollution in Singapore... that's why the light pollution and low cloud at night look reddish/orangish due to the low clouds and air particles reflecting the orangish road light.

Milky way is very big, so you can't use a telescope to see it... bino and naked eye is the best way to see it. Anyway, you can see the brightest part of the summer milky way in certain area in Singapore (when the sky is very clear) as a small hazy patch using your naked eye or a bino.

By the way, welcome to SingAstro!!

Have a nice day.

tyty!! [smilie=cute.gif] [smilie=cute.gif]



i think i have a bad eyesight when i look at the orion constellation all i see

is 3 stars in a line no nebulae [smilie=beaten.gif]


so with a bino i can trace out the milky way in sg during clear weather

conditions even with bad light pollution?


whats the summer thing? theres no summer is sg i dont know when lol

The surface brightness of M31 spiral arms is low, so basically washed out by the light pollution in Singapore.

Anyway, although you can image the spiral arms of M51 in Singapore, you also can't see the spiral arms using modest size telescope. Basically, you can only see the core of the 2 galaxy of M51 as two very small patch of light.

Have a nice day.
