If you want some help finding your way around the night sky then consider the Celestron StarSense Explorer DX 102AZ, which comes with a smartphone holder and an app to create a night sky sat-nav. If the Celestron Inspire 100AZ telescope isn't for you If you want to avoid the bottom of the market but don't want to spend big, the 100AZ is an appealing solution. The icing on the cake is its clever lens cap, which turns into a smartphone holder for astrophotography, which instantly gives it another dimension. The build quality - particularly its tripod - is a step up while its aperture is just enough to allow beginners to explore objects beyond the solar system. It's not perfect and it excels and like most refractors, it does its best work with the moon and planets, but the Celestron Inspire 100AZ has more to get excited about than many of its cut-price rivals. Should you buy the Celestron Inspire 100AZ telescope? It's worth noting that because of its rather unusual hood design the Celestron Inspire 100AZ can't take solar filters, so should never be used to observe the Sun.

It works well, though it pays to be quick about setting it up because once you've lashed your smartphone and secured the eyepiece your target will have drifted out of view. The giant planet Jupiter is one of the easiest planets to find and observe in the solar system.

With everything snugly in place, the eyepiece can then be inserted into the diagonal with a smartphone perfectly positioned to begin taking a focal photographs. The rack and pinion focuser is easy to grip when wearing gloves, but poor quality.
