Skywatcher AZ-GTi WiFi head for mount #20315

Weighing just 1.3kg, the Sky-watcher AZ-GTi is now available as a mount head only, and can be connected to a tripod via its standard 3/8″ tripod bush. This will help cut down costs if you already have a sturdy mount with standard camera thread.

With so many gadgets and electronics nowadays being controlled by many smartphones and tablets, the new Skywatcher head is future proof.

The excellent value for money and highly portable Sky-Watcher AZ-GTi Alt-Azimuth Mount, with it’s built-in WiFi module, has been designed to be controlled wirelessly with your Smartphone or Tablet, using the free SynScan App for iOS or Android.
The AZ-GTi creates it’s very own Wi-Fi network, so the mount can be used anywhere, without any reliance on other WiFi networks. After entering your coordinates into the App and following a simple alignment procedure, you are ready to explore the universe using the App’s intuitive touchscreen menu.     The AZ-GTi and SynScan App provides full computerised GO-TO control, allowing your telescope to be automatically slewed to any one of the objects in the App’s extensive database of 10,000+ celestial objects.

Incorporates Sky-Watcher’s Freedom-Find™ patented Dual-Encoder Technology, which allows the telescope to be moved manually in either axis without the mount losing its positional information. This gives the user enormous freedom, convenience and flexibility during observational sessions.                             The mount is quiet in operation, has a payload capacity of up to 5kg and accepts telescopes with standard 45mm Dovetail Bars.

Skywatcher Solarquest GOTO tracking mount with tripod #20320

Finding the Sun for solar observing can be tricky, even using a finderscope with a solar filter. But no such issues with the new Sky-watcher Solarquest GOTO tracking mount + tripod. All you need to do is level the tripod and point the scope anywhere to the left of the Sun. The Sky-Watcher’s revolutionary HelioFind™ Solar Alignment Technology automatically will do the rest!!

At the single push of a button, the telescope will be auto-levelled and the mount via GPS data fixing will calculate the altitude and azimuth of the sun based on the time and location. The telescope will then be pointed to the correct altitude and the mount will slew clockwise hunting for the sun. The Solar Sensor will detect the sun and lock onto it, and will silently track and keep it within the eyepiece’s field of view indefinitely.

The SolarQuest™ mount can be used by educational establishments, beginners and experienced observers alike. When mated with your solar telescope it is a great companion when observing sunspots, solar eclipses, solar surface details & the transit of inner planets across the sun.

The SolarQuest™ mount is lightweight and portable, quiet in operation, has a payload capacity of up to 4kg and accepts telescopes with standard 45mm Dovetail Bars.

IMPORTANT NOTICE: The SolarQuest™ mount is designed to be used with solar telescopes only. Do not point any other type of optical device at the Sun. Looking directly at the Sun without verified-safe, professionally made solar filtering will cause immediate and irreversible damage to the eyes (blindness), damage to the telescope, and will be a fire risk. 


  • HelioFind™ Solar Alignment Technology: Solar Sensor with 4 x Photodiodes & built-in GPS data fixing to obtain time & location to calculate the sun’s azimuth and alltitude
  • Telescope Auto-levelling feature with the help of the built-in tilt sensor (3 x axis accelerometer in the sensor block).
  • Auto drift correction through feedback from Solar Sensor

Skywatcher EQM-35 pro synscan GOTO mount #20980

The new modular design of the Sky-Watcher EQM-35 computerised mount is suitable for use at home or on the move. Leave fully set up for use at your address, or when on travels you can remove the DEC Axis together with the heavy counterweight shaft and counterweights, reducing the instrument’s weight considerably.

Easy to use and set up with the Skywatcher SynScan GOTO system giving you a massive database of 42,900 objects.

This amazing design means you do not need to purchase two different mounts for home and away.

In this configuration you can use a simple 45mm dovetail plate with tripod screw (not supplied) and fit your camera directly using a ball head (not supplied). Alternatively a DSLR can be mounted to a Sky-Watcher Star Adventurer L-Bracket (not supplied). With the DEC axis removed the mount only tracks in RA and you can easily take photos. Now the mount works in a similar way to the Star Adventurer mount, but heavier duty.

The mount head bears some cosmetic similarity to the EQ3 PRO but it has much improved features and performance. For example the mount is equipped with a large 92.5 mm diameter RA worm wheel with 180 teeth for high precision tracking (compared to 130 teeth for the EQ3). Also the strength of the rotary base has been increased. This results in much greater stability, higher payload capacity and less vibration. Through this the periodic error is also greatly improved.

The EQM-35 PRO SynScan is a conveniently sized mount with impressive features suitable for both novice & experienced astronomers alike, for both visual and imaging use.

  • Positioning Accuracy up to 1 arc minute. Accuracy enhanced by software collimation error (mount mechanical error) compensation.
  • High Precision Stepper Motors with 1.8° step angle and 64 micro steps driven.
  • Resolution 0.28125 Arc Second
  • Slewing speed up to 3.4°/sec (800X).
  • ST-4 type Autoguider Interface: Supports 0.25x, 0.5x, 0.75x 1x guiding rate
  • Dual or Single Axis Tracking
  • Tracking Rate: Lunar, Solar or Sidereal
  • Synscan™ Hand Controller with 42,900+ Object database containing complete Messier, NGC, and IC catalogues.
  • Periodic Error Correction.
  • PC compatibility.
  • Synscan Handset Firmware Upgradeable  via internet download.
  • Supplied with Polarscope
  • Latitude Adjustment 15° to 65°

StarGazingLincs blog 2018

Was very kind of Paul Cotton from the East Lincs astronomy society to invite Northern Optics to attend StaGazingLincs 2018 as the optics trader for the event.

It was a very well attended event with lots to do to keep both adults and children occupied. Bargains which attendees snapped up from the Northern Optics display were Ostara 2″ SWA-70 eyeieces. These ever popular wide field eyepieces give excellent views for under £100.

Another customer grabbed the chance to purchase a Skywatcher Nirvanna 28mm 2″ eyepiece. This beast of an eyepiece (pictured) gives an amazing picture window field of view. Other bargains customers purchased were illiusion 7×50 binoculars and T2 dust caps

Helios Nitrosport 8×26 binoculars. Northern Optics blog 10.2.2018

We often find at the Northern Optics weekend display , given the choice of 8x and 10x with the same make and model of binocular, most people go for the 8x. This this exactly what one of our customers did at the Waters` edge visitor centre at Barton Upon Humber.

After looking through some 10x, the 8x version gave a wider, brighter view with closer focus. But do not let this put you off. When looking at more distant targets, or planes and ships at sea, the extra 2x gives you the close up detail you require.

Another advantage of lower magnification is they are easier to hold steady and give a slightly larger depth of field.

Everyone is different, and has different subjects to look at. So if possible always go to an outlet where you can try different binoculars.

Celestron Cypress 10×25 binoculars. Northern Optics blog 15.2.2018

The Celestron Cypress binoculars were the Optics of choice when a customer came to the Waters` Edge visitor centre Northern Optics weekend display at Barton Upon Humber.

Other sets tried in the similar price range were compact 8×25 , 8×26 and 10×26 roof prism designs. But the porro prism 10×25 Celestron Cypress binoculars, from the customers point of view gave an instantly brighter image.

I find compared to the usual roof prism compacts, the porro prisms like for like in optical quality give you the edge with the slightly larger prisms. Not everyone likes the feel of compact porro prisms. Seems to be a love , hate reaction. But if you can get to grips (excuse the pun) with the shorter, wider body, there are some excellent choices out there.
