Question 1

I am planning to buy my first telescope - how good is this for an amateur? Also, do I need to buy anything separately to get started with this one?

Accepted Answer

This is great for an amateur. You'll get great views of the moon and the brighter Messier objects (nebulae and so on). With a high magnification eyepiece you'll be able see the planets too. You don't need anything else up front but if you want to observe for a long time, you'll find that the go-to motor chews through batteries. You can buy a mains adapter to run it from a household electricity in your garden, or an external battery pack, or an adapter to run it from your car cigarette lighter if you're further from home.The kit comes with two eyepieces which are OK. In future you may wish to upgrade them to nicer ones, but wait until you've reached the limitation of the bundled ones before you take the next step. Then you'll know better what your needs are.Finally, these telescopes don't come with any carry case but they are delicate items. You can buy dedicated custom cases which are expensive, but I cheaped out and took the telescope to B&Q and found a sturdy toolbox that was the right size. I lined it with custom-cut foam from a fabric shop and cut out a shape for the telescope and the eyepieces to go into.

Question 2

I am a little confused about eyepiece size. The description seems to indicate that it is 2", where-as 1.25" appears to be the norm. What is it?

Accepted Answer

1.25 is the norm. The 130SLT has a 2" tube for eyepieces which is fitted with an adapter to take 1.25" eyepieces - the two eyepieces that come with the kit are 1.25". If, in the future, you want to use a 2" eyepiece you just need to unscrew the adapter.

Question 3

Hello all..new to this..would I a novis be getting the right one ?...... I am so looking forward to learning as have the time now..60yr old bricky..worn out ha ha...any advice would be greatfully received, many thanks
David..would love to see Jupiter's moons etc

Accepted Answer

It's never too late to start! The 130 SLT is a lovely telescope and you can see Jupiter's moons with it and just about make out the stripes on the planet. It tracks well with the computer aligned correctly but it absolutely scoffs batteries so I would recommend a battery pack or dc transformer (this would require an extension lead so the battery pack may be better but is more expensive).So far I have been really pleased with it as a beginner astronomer!Good luck with your choice!!

Question 4

Is it possible to control the movement of the mount via a laptop?

Accepted Answer

Yes, using a serial connector to the lap top (or usb to serial adapter if the lap top does not have a serial port) and a cable that plugs into the bottom of the handset.  The Celestron web site has further details.
