I bought myself a secondhand Tasco Telescope recently, to look at the stars etc.

I have no experience whatsoever, but something seems strange to me.

When I look through it during daytime, all objects seems to appear upside down :redface: :hmz:

I changed the lens with some others I got with the deal, but still, no improvement.??

Can anyone explain why this is, or does it have to be like that?

Thank you,

Feeling really :wall:

Astronomical telescopes don't have prisms to invert and reverse the image as do binoks and spotting scopes . Astronomers just learn/adjust their brains , to see the heavens reversed as do the star charts .

BTW your mirror also has a reversed image (but not inverted) , and you have learned to shave and brush your hair (but not read) from this image .

A basic physical science textbook on optics will explain all this .

Thank you MikeV,

That helps a lot. So there is nothing wrong with it then.

But now's the questions WHERE does one start looking for stars etc.???

Usually you look up. :roll:

I think it's called a spotter scope, DQ.
Or you can get a nice motorized computerized thingie which plugs into your laptop and will find the stars for you. I have no idea how it works and I can't afford one either.

Where are the clever okes?
Deeftes!! :yaya:

Now for some seriousness though :shock: - it might sound boring but try looking at a couple of the planets first especially with a new instrument. Most good telescopes will give you jupiters rings and some of the moons.

There is some decent software on the net that allows you to plug in your co-ords and provides you with the night sky at different times. One you find what you are looking for with the naked eye then use the spotting scope to line up, have a quick drink to get rid of the jitters :twisted: and then hopefully you'll have a star in your sights.

Any area with light pollution makes it tough, so the darker the better. I was working up north on one of the minesites and there was an OP set up about 2 kms from the mine / living quarters - what a difference when there is absolutely no light pollution.

Hello all,

VERY much a n00b to astronomy. I have my first telescope and now I want to get it set up and start star gazing.

I have search the web for "how to align an equatorial mounted telescope" only problem is that all the articles are written by people in the Northern Hemisphere, :hmz: so when it comes to setting the Polar alignment, they just say point it at the north star, that particular bit of advice does not really help me at all. :huh:

So I would like to know how do I set the polar alignment in the southern hemisphere?

Regards

It is tricky in the Southern Hemisphere...

You have to start by pointing it at the "Celestial South Pole"

You can find this by extending the the Long side of the Southern Cross 4 times.

Then take a 90degree line from the two pointer stars and where it intersects the Southern Cross line is the Celestial South...

This is all Eyball method and not very accurate. With my equatorial mount I start this way, then when I use the "Goto" handset with the first star, I reset the mount exactly on that star and then start all over from landing position...

Hi guys, just received an early Christmas present, always wanted one, but have no clue on how to start :wall: . It included an amazing program called"the skyX first Light edition", that looks amazing. I put the telescope together as per the instruction manual, but it has a little focus gadget stuck to the side on top, that I don't know what to do with? :redface: I took it outside the other night and saw zero!! Am I supposed to focus :hmz: with it? I AM COMLPLETELY CLUELESS AS TO HOW TO START WITH THIS THING, PUT IT WHERE? POINT IT WHERE? HOW TO FOCUS?? HEEEELLLPPP PLEASE???

Howzit Fatcat!

My SO bought one about 8 months ago and had no probs with the setup. I will get him to give you some advice tonight if someone else does not beat us to it.

Chat Later!

OK, here goes - just checking - you should have also received a little box containing lenses.
Mark says to attach the 20 mm lens first (to see if you can make out anything)
Also use the sighting scope (mounted on top of the 'barrel' AND VERY SENSITIVE) - the purpose of the sighting scope is to give you a rough indication where in the universe you are aiming at.

Please feel free to contact us if you battle. I will get him to phone you and talk you through if needed.

Good Luck!!!

lee

Thanks again Lee, I was wondering what the side "jobby" was for :redface: on the side / top. Yes I did get the lenses as well. Will try it soon, I have a lot of tall trees around my property and tall roofs as well, now of course we've had clouds for a few days, but I'm not complaining - we need the rain. Thanks for your kind offer :D , if I get stuck I will contact you

I suppose it depends on how seriously you take it and what you want to look at. For example, I'm still learning about basic constellations and astronomy, so even if I had a telescope I wouldn't how to use it or what to look at.

I imagine you can go quite far with just binoculars.

I think a long lens (400 mm or more) would be more usefull?
You can take photos with you then, to peruse later, and you will need that lens for birds and animals further away anyway.
A canon 100-400 only weighs 1.6 kilo, so that should not stop you.

I have long and short lenses, plus zoom for Pentax camera, do not like digital cameras.
This is the Celestron scope for star gazing tracking, that weighs so much, but is not tool set up on the tripod its great, but heavy (D... baggage allowances)
