Buying your second telescope: a guide to astronomy upgrades

On the hunt for a telescope upgrade? We've selected some of the best pieces of kit that would make an excellent second scope.

Deciding what to buy when choosing your first telescope is a tricky task, but perhaps even more difficult is deciding what ‘scope would make a decent upgrade. Once you’ve decided that practical astronomy is definitely for you, it may be worth investing in a more powerful piece of kit.

Sky-Watcher EVOSTAR-72ED DS-PRO (£269)

Sky-Watcher Evostar 72ED DS-Pro refractor telescope

Small apo class refractors used to be quite heavy for their size but small scopes from Sky-Watcher and other manufacturers have brought the weight down. This scope’s tube weighs just 1,955g.

It’s only 42cm long, so it’s a very short tube system, and the dew shield is removable, adding up to a great get-up-and-go telescope, perfect for taking on holiday for viewing and imaging. The whole system is quick and easy to set up: a great incentive to invest.

Omegon Pro ProDob N 203/1200 8-inch Dobsonian (£350)

Omegon ProDob N 203/1200 telescope

Assembly is intuitive and straightforward, and once collimated this scope holds alignment quite well. A 32mm super wide angle eyepiece, mirror-cooling fan, battery box and red dot finder complete the system. Remove the tube’s front cover, switch on the finder, drop in an eyepiece and you’re ready to observe.

We were impressed with great optics and friction control on the altitude and azimuth axes. This would be great for experienced astronomers who want a simple scope to reconnect with the skies.

Bresser Messier 8-inch Dobsonian (£399)

Bresser Messier 8-inch Dobsonian

This scope comes with a red dot finder, 25mm Plössl eyepiece, extension tube for the focuser and an eyepiece rack. Bresser have used furniture style fittings, allowing you to build the base quickly. The rocker is lightweight and convenient for taking to a remote site.

Tube rings hold the telescope, to which altitude wheels can be attached for Dobsonian usage. Or the wheels can be removed and a Vixen dovetail bar attached in place of one or both. This enables you to mount it onto an equatorial mount, allowing you to track the night sky and use the scope for long-exposure astrophotography.

Bresser Messier NT-150S/750 reflector (£446)

Bresser Messier NT-150S reflector

This scope comes with a 6×30 finderscope, focuser extension tube, piggyback camera attachment, 2- to 1.25-inch adaptor for the focuser and a 26mm Super Plössl eyepiece. Collimation was relatively easy as the rear of the telescope has good-sized collimation knobs and easy to access adjustment screws.

Deep-sky targets looked great, with a good deal of nebulosity when we viewed the Orion Nebula through the supplied 26mm eyepiece. The Messier NT-150S and its accessories weigh in at just 5.5kg, so it is lightweight and easy for most people to handle.

Starwave Travel 70 EDT-R apo refractor (£599)

Starwave Travel 70 EDT-R apo refractor

This refractor is a cost-effective travel option, as it is supplied in a soft, well-padded case with compartments for accessories. A doublet design helps correct any colour fringing around bright stars.

The dew shield performs its job, while the back section of the scope can be rotated 360º, which gives you more flexibility when framing targets for imaging. It is also light at just 2kg, and its case will likely fit within most airline luggage restrictions.

Orion Optics VX8 Newtonian reflector (£600)

Orion Optics VX8Newtonian reflector

The VX8 is a lightweight system, and without accessories weighs just 7kg. It comes with a straight-through 8×50 finderscope, ACU-2S 2-inch Crayford focuser with a 1.25- to 2-inch adaptor.

The primary mirror is supported by a nine-point cell with easy collimation and, after a few simple adjustments, we quickly had Altair pin sharp across 80% of the view. At the edges there was a little coma, but this is to be expected in ‘fast’ systems with shorter focal lengths.

William Optics Star 71 five-element apo refractor (£1,199)

William Optics Star 71 five-element apo refractor

William Optics’ Star 71 comes in a package comprising an optical tube, tube rings with a Vixen dovetail bar, 2.5-inch dual-speed rack and pinion focuser with built-in thermometer, front and rear metal covers and an M48-Canon EOS adaptor ring. It is first and foremost an imaging instrument.

We attached our Canon EOS 50D DSLR and set on an NEQ6 Go-To mount, giving us the ability to capture exposures of up to 4 minutes without guiding. This is a compact imaging telescope that gives sharp stars out to the field edges and good colour correction. We’d recommend it to anyone interested in wide-field imaging.

Celestron NexStar Evolution 8 (£1,980)

Celestron NexStar Evolution 8

Evolution 8 is an 8-inch Schmidt-Cassegrain telescope on a computerised single 
fork arm. The altaz mount is on a stainless 
steel tripod and comes with a star diagonal, red-dot finderscope, 40mm and 13mm eyepieces and a mains power cable. The mount’s single arm includes an integrated lithium-ion phosphate battery. When charged up you don’t need an external powerpack.

The mount also works with the power cable connected. It comes with a built-in Wi-Fi network so you can control it with your smartphone or tablet. Optics are Fastar compatible, so the secondary mirror can be replaced with a Fastar/HyperStar unit onto which a CCD camera can be mounted. This speeds up the scope’s focal ratio by a factor of five 
to f/2 – especially useful for deep-sky imaging.

Meade LX65 8-inch ACF telescope and mount (£1,285)

This scope comes with stainless steel tripod, 26mm eyepiece, red dot finder, star diagonal, bubble level with compass and planetarium software. The tube is a Meade ACF catadioptric with a diameter of 8 inches and a focal length of 2,032mm giving a focal ratio of f/10.

It is ideal for high-resolution planetary and lunar viewing or imaging yet still gives good views of a wide range of deep-sky targets, especially double stars.
