Fantastic telescope, if you are prepared to have patience in learning how to use it. Using such a high-power telescope isn't easy and it can be hard to get good, clear viewing.

The GoTo calibration isn't always accurate and it might take 2 or 3 attempts to get the telescope aligned before you can start using it. It's important to set the time correctly and to make sure the tripod is absolutely level before you begin. There's a spirit level for this purpose, but you have to be spot-on. Once aligned, the GoTo functionality is easy to use.

I almost regret getting a GoTo telescope because I haven't actually learnt all that much about astronomy (although I have had fun). With a manual telescope I would probably have learnt more, but used it less - swings and roundabouts!

The telescope takes 8 AA batteries and runs them flat in a couple of hours, especially if it's cold. Rechargeable AA batteries don't work well because of the lower voltage, so you do need to invest in good alkaline batteries. Alternatively, the telescope has a DC power socket so you can use an external power source. You could hook it up to a 12V lead-acid leisure battery which will keep it running for many observation sessions, or if you plan to use it in your garden, you can use a 12V DC transformer and an extension lead. Make sure to check the maximum current rating because the telescope is quite demanding.

Optically, this Cassegrain-Maksutov telescope is better suited to planetary viewing. If you want to look at galaxies, nebulae and other DSOs, you would be better off choosing a Newtonian formula telescope such as the SLT 130. Newtonians have lower magnification but better light-collecting ability.

I think this is a great little telescope. I recently sold my C6-SGT as there's not much room in my house and I was tired of stubbing my toe on it, so I thought something less-heavy and occupying less floor space would be just the ticket. So I bought a Celestron 127 SLT.

Coming down from a C6, I thought there would be a significant trade-off in optical quality, both in terms of power, resolution and light grab, but it isn't immediately apparent, with bright, clear viewing. All my long eye relief eyepieces work well with it, and I don't need to use the 9mm and 25mm plossls that come with it, though there is nothing wrong with them. Through a Celestron 5mm X-cel, the banding and red spot on Jupiter are both easily discernible I'm happy to say that the little 127mm Maksutov copes very well, with excellent resolution and contrast. If the optical tube has been built down to a price then it isn't immediately noticeable and can easily cope with 300x. I really can't find fault with it optically; this is one powerful little telescope.

Celestron goto system is great and easy to use. Takes about 2 minutes to set the telescope up ready for viewing

The tripod, however, is a different matter. This telescope deserves something a little more sturdy, even if it added £50 to the price. Only other bugbear is the rear thread on which the eyepiece assemble is mounted. The thread is too small to accommodate my focal reducers and I can't seem to find any that fit on the internet. Hence, the 127 SLT is best used for planetary work. If galaxies and star clusters are your thing, then something with a shorter focal length might suit you better.

The Celestron Nexstar 127 SLT is an excellent and affordable Goto telescope. Perfect if you are looking to upgrade from smaller aperture models or if you are looking to purchase your first Goto. It is quick and easy to set up and the Sky Align software generally works very well, although for optimum performance the scope needs to be dead level (the built in bubble level will help you achieve this) and you need to choose three bright objects that are well separated in the night sky-otherwise you will probably get an "alignment fail" message and need to start over.

Some scopes suffer from a software bug that manifests itself as a "bootloader error" message. If this occurs, the scope will be unusable until the problem is resolved. This happened to me once and it was necessary to re-flash the handset through a free software upgrade via the Celestron website. No big deal - thankfully the problem has not reoccurred and the scope continues to give me hours of viewing pleasure.

The 127 SLT is best suited for observing bright solar system objects. The Lunar surface is breathtaking and Jupiter's cloud belts and Saturn's rings appear clear and well resolved. However, I did upgrade the supplied eyepieces with Revelation plossls. Due to the long focal length the scope copes less well with nebulous deep-sky objects and galaxies which generally appear as smudges of light through the eyepiece. Consider something with a wider aperture / shorter focal length if these are your thing.

Not suitable for "serious" astrophotography due to the Alt-Az mount; respectable images can still be obtained through short exposures with a DSLR camera or webcam.

I agree with other reviewers who have commented about the tripod.
