I live in a fairly rural location, and I usually walk my dog most evenings. Sometimes, away from the glare of the street lamps, I often see some staggeringly good night skies.

 

 

On occasion, I can just stand there looking up, and stare in awe at the number of stars, and even the cloudy spiral of our Milky Way suburb.

 

 

That is all.

 

 

I do the same when i am out walking our dog at night.

 

I have been a space geek since a young lad, never ventured down the academic road unlike my wifes cousin who is out in S.Africa working with SKA. 

 

Remember taking my lad to Dynamic Earth on one of there tours and at the end there was the celestial one of our solar system.

 

You sat back in your chair, lights went out and upon the ceiling  there started a documentary like viewing of our solar system and the work of  Hubble. Was brilliant , the graphics were great too, had a wee private tear in ones eye at viewing all that.

Great view of the Full Moon rising, in a briefly clear sky, over the M8 tonight.

 

Not, although, a night to be out sky-watching.

Gave up trying as I can't feel my fingers.

 

Tried setting it up and all seemed to be going well as it slewed automatically to a couple of stars that I can't remember the names of but couldn't see anything through the lens.

 

Doesn't help when you don't have a manual.

Is there no YouTube guides/tutorials available for your model?

Just found a manual online so will have a good read at it and try again tomorrow :thumbsup:

After a one on one discussion with the Mrs and a promise from me that i will be a good boy until my birthday she has agreed to get me a telescope for my birthday.

 

Of course i was right on the web looking for one within the budget we agreed,(well mostly her), on, found this one or something similar along its design.

 

There is one going for ?109 , second hand probably.

 

Still five months to my birthday though.. :sob:

 

The Celestron Powerseeker. :laugh4:

 

Sounds like its straight out of a Marvel comic.. :laugh4:

 

 

 

 

  • Explore the universe and the world around you with this Newtonian reflector telescope;
  • Capable of up to 269 times magnification (using Barlow Lens) to see to Jupiter and beyond; :laugh4:
  • Comes with two eyepieces (20mm and 4mm) and a 3 times Barlow lens to customise your telescope for the best view.

Better buying a pair of binoculars than that scope. Cheap scopes are awful. The tripod on that won't be very steady and will frustrate the hell out of you.

Really?   :oldsad:

 

So no chance of seeing Jupiter and beyond as was advertised on that model then..   :laugh4:

 

What scope would you recommend? :mw_confused:

Set my travel scope up for a look at the moon tonight. Tried for a couple of pictures but too much wobble from the wind.

 

Stunning view tonight though if you pick your moment between the cloud.

Wait till the moon is about a third or a quarter. That way it's not so bright on your eyes and you will see the shadows of the mountains along the terminator line.

You will see Jupiter easily with binocs. If it's the four moons you want to see then a cheap scope would do it.

A moon filter is also a relatively inexpensive piece of kit too.

 

Works very well on mine, I've found.

I've been into Astronomy for as long as I can remember. Parents bought me a wee white Argos telescope when I was about 10 or something. Crap, but got me interested.

 

I have quite a good pair of binoculars just now. Nothing fancy, but they do the trick. I had a quick look at the moon last night and it was stunning, so much detail in a full moon.

 

The missus got me a couple of tickets to go and see Professor Brian Cox live in March, can't wait because I've always been a huge fan of his work and the way he speaks about the Universe.

This link has some good advice for star gazing binoculars.

 

There was a lot to consider: magnification versus mass, field of view, prism type, optical quality ("sharpness"), light transmission, age of the user (to match "exit pupil" size, which changes as we grow older), shock resistance, waterproofing and more. To choose binoculars for yourself, check out our Buyer's Guide: How to Choose Binoculars for Stargazing.

 

Still want a telescope though.

Surely your hands would be far too shaky for binoculars?

My trick is to lie on the ground and look up with binocs sort of balanced on my eyes so there is no shake.. Works for the andromeda galaxy which is high in the sky but less good for the lower azimuth stuff.

 

Binocs can also be mounted on tripod if you have a fitting.

 

Scopes are of course better but need to be continually slewed to follow the target. If I had cash I'd buy a scope with the computerised identification thing. That slews automatically and you just hit a button and it goes to wherever you choose. Pain in the ass to calibrate though.

In Fife at present and the sky is very clear. Looking in a southerly (ish) direction, what is the very bright and prominent 'star'? It's impressive.

Venus i think.

 

In order from their outward order from our  sun , the five bright planets are Mercury,Venus, Mars, Jupiter and Saturn. They tend to be brighter than the brightest stars.

Can one see Mercury at night time?  Genuine question.

 

I always thought that you could only see it in the daytime, with special filters on the telescope, as it's so close to the sun.

It's Venus. A bit north-west of Venus and much fainter is Mars

Found the answer to my own question:

 

Stargazers have the best chance of the year to spot Mercury in the evening sky over the next week, but only if you know how to find the elusive planet.

Like most of the planets, Mercury is quite bright, among the brightest objects in the night sky. Despite this, it is probably the least often seen of all the planets.

The problem with Mercury is that it never strays very far from the sun. It can be seen occasionally as a tiny speck just after sunset or just before sunrise, but most people, even serious skywatchers, have never seen it. In fact, it is said that famed Johannes Kepler, who figured out the laws of planetary motion, never saw Mercury in his entire life in the late 16th and early 17th centuries

Just set up my telescope the Mrs got for my xmas the year before last (took me long enough) due to this thread [emoji1303]. Adjusting it seems tricky though so will go back to it in a bit. That moon earlier as it was rising was stunning, was bright orange from where I was looking, stunning and biggest I can recall seeing it before.

You would be better off googling it.

The measure of light years is fascinating. If a huge detonation on the moon was initiated, how long (in seconds or minutes) would it take for this to be visible from Earth? Likewise, what would be the timescale if the same was to happen with other planets that are visible from Earth?

For the moon it's 1.3 seconds.

The sun is 8 minutes.

 

Jupiter is about 30 I think.

Light years is typically the measurement used between stars.  The closest star is 4 light years away.

 

For measurements within our solar system, Astronomical Units is the standard.  By definition, the earth is one AU from the sun.

 

Going outwards, Jupiter is 5 AUs out, Saturn 9, Uranus 19, and Neptune 30 AUs.  Vast distances.

There she is Mars , my favourite planet.

 

Mars.jpg

 

 

 

Would love to be able to see a clear picture of her from a telescope.

 

Hopefully one day man will land on her and maybe even colonise her, NASA are working on the maths and science needed as we speak.

 

 

Here, a landscape image captured by NASAs Mars Curiosity rover ;

If you have a scope or binocs Mars is clearly visible tonight if the clouds clear. Find Venus, go left a bit and up a bit and Mars is clearly visible to naked eye.

Thats just it, i have neither just now, :ermm: only a naked eye.  :smart: Its going to be a long six months until my birthday when i get some kind of viewing paraphernalia. :sweat:  

 

Cheers for the info.

The post about the SKA in South Africa is interesting.  Why will it take better images than Hubble?  We all know that Hubble gets good images because it doesn't have to contend with the distortions created by the earth's atmosphere.  To say that earthbound SKA images will be 10,000 times better than Hubble is quite a claim.  Not a hundred times, or a thousand times ... but 10,000 times better?   Hmm.

 

And why is the SKA so superior to the existing VLA in south western United States? My interest is tweeked.

 

The James Webb telescope's images will easily outshine all that's gone before ? including Hubble.

Actual footage shows what it was like to land on Saturn's moon Titan

Few of us will ever get the chance to travel to space or discover another planet.


But now you can follow the journey of a probe landing on Titan, the planet Saturn?s moon, thanks to this footage from the NASA Jet Propulsion Laboratory and the California Institute of Technology.

The last image is called the "pillars of creation" were young stars,(suns), are formed.

 

 

This image below is called "the mystic mountain". Again a star,(sun), forming region inside the Carina Nebula.

 

 

Mystic-Mountain.jpg

 

 

 

Its mind-blowing to even comprehend the amount of energy and force generated and needed to form young stars or suns.
