Celestron Nexstar130SLT - Alternative mount?

Hi, I have a Celestron NexStar 130SLT Reflector on a GOTO pro mount but I have several problems with this mount - one is that I can never get it to do a 3 star alignment - it constantly says alignment failed) and secondly I hate the automatic mount - I would rather point my telescope at a space in the sky and look through - is there an alternative mount I can get that ...

Evan's mum needs telescope advice!!

Hi there. I hope I'm writing this in the right part of the forum but I'm looking for some help and guidance. My 5 year old has a obsession with planets and for Christmas this year has asked for a telescope to go with his planetarium. I'm willing to pay up to £200 but after reading review after review I'm struggling with which is the best. My boy has slight autism and is highly dedicated ...

Please help, what is the difference between these

Hello, I'm looking to purchase a telescope, am brand new to all of this. I have seen this one but found it for two very different prices. Please could someone advise if there is a lot of difference between the two kits and if the one is worth the more premium price tag?

Hyperstar

Hello.
Has anyone had any experience using a hyperstar lens on a Schmidt Cassegrain telescope? Are they difficult to use, are the results good? Any information would be gratefully received.
Thanks

The Sun: Why Doesn't It Shrink?

The Sun is supposed to be a giant ball of compressed hydrogen gas. The compression makes it operate as a kind of thermonuclear reactor, continually using up the hydrogen as fuel.

If this is true, the hydrogen in the Sun must be getting "used up" all the time. So shouldn't we see some sign of this, for instance by observing a shrinkage of the Sun? Yet we don't see this. The Sun seems to stay ...

Universe too big or too young?

Hi, would be interested to know what explanations astrologers have for the following anomaly- If our universe is estimated to be around 13.8 billion years old (time from big bang to present day), and the size of the observable universe is estimated at 92 billion light years (so its 46 billion light years from the center to the edge) ... and if both those things are true then the average speed of the matter now ...

Dark Matter Black Holes?

On the basis that Dark Matter exhibits the property of mass is there a theoretical possibility that dark matter could therefore ultimately form a Singularity and if so how might this present itself?

Thanks

Expansion speeding up

Could the increasing rate of expansion of the universe be explained by either the universe slowing down at an increasing rate from the outside in or similarly could it actually be imploding at increasing rate from the outside in. Has it actually been proven that everything is moving away from each other?
