August promotion: iOptron CEM40 now at reduced prices

August 2 2023, Jan Ströher

CEM stands for centre-balanced equatorial mount, that is a mount supported at its centre of gravity, thanks to its design. This means that a lighter counterweight can be used, and it offers an excellent ratio of mount weight to carrying capacity: a CEM with a relatively low own weight can carry a comparatively heavy optic.

We are now offering the CEM40 series of mounts from iOptron at reduced prices for a limited time until 31 August!

The CEM40 mount weighs just 8.2 kilogrammes, but can carry optical instruments and accessories weighing up to 18 kilogrammes. This excellent payload/weight ratio of 2.5 is the reason why the CEM40 is so versatile. You can transport them to the best dark sky observation sites, or mount them on a small column in your garden observatory.

The following models in this series are available in August at a discount:

CEM40 GoTo with LiteRoc tripod and carrying case – 63903

CEM40 GoTo LiteRoc – 62121

CEM40 GoTo with tripod – 61904

CEM40-EC GoTo high precision encoder with LiteRoc tripod – 62122

CEM40-EC GoTo high precision encoder with tripod – 61906

As always, this promotion is on a “first come, first served” basis and only as long as stocks last!

Promotion period: 01 to 31 August 2023.

New version: the Polarie U star tracker mount from Vixen

October 28 2021, Stefan Taube

A few years ago, the Japanese manufacturer Vixen launched the Polarie, the first tracking unit for cameras that can fit in every photographer’s bag. The tracking device, also called a star tracker, compensates for the celestial rotation. With it, a camera remains aligned with a section of the night sky for many minutes, and can gather light from faint stars, the Milky Way and cosmic nebulae.

Vixen now offers a new version of its successful star tracker mount, the Polarie U Star Tracker.

Polarie U star tracker mount with camera and optional ball head

Compared to the classic Polarie, the new Polarie U is significantly lighter whilst at the same time having a higher load-bearing capacity. The distance between the two bearings supporting the rotating shaft is approximately four times that of its predecessor. This has led to a higher load-bearing capacity despite a 20% weight reduction. It can carry 2.5kg for wide-field astrophotography using lenses with a short focal length. The optional mounting accessories comprising a prism rail and counterweight can be used to increase the load capacity to 6.5kg, so that the star tracker mount can also carry cameras with large lenses.

In addition, the  Polarie U creates its own WLAN. You can connect your smartphone to the mount and control it using a free app. With a suitable cable release from the Polarie U accessory selection, you can also control the camera itself via the app, for example to set a series of exposures. This is not only convenient, but also very useful thanks to the hands-free operation.

The Polarie U can of course also be converted for use in the southern hemisphere. The lightweight mount is therefore ideal for your next expedition south of the equator.

New: Deluxe equatorial wedge for Omegon MiniTrack

August 27 2021, Marcus Schenk

Using the latest deluxe equatorial wedge, aligning the MiniTrack with the north celestial pole is easier than ever. The advantages? Spherical stars all night long.

How do you align your MiniTrack and other astrotrackers without an equatorial wedge? In theory, this is possible using a tripod head but the alignment and the fixed support sometimes resemble weather forecasting, in a word: uncertain. And yet, the photography session is meant to be a success.

The right tools for success

Thanks to the deluxe equatorial wedge, you can simply and precisely align your MiniTrack with the north celestial pole. It’s easy peasy lemon squeezy!
A robust locking mechanism provides permanent polar alignment, even when you are continuously focusing your camera on new targets.

In our set-up, we use an Omegon 32mm carbon tripod, the deluxe equatorial wedge and a MiniTrack 3 with pole finder.

Simple installation on any tripod

Using the 3/8 inch thread, you can attach the polar wedge to any camera tripod. To do so, you simply need a mini Vixen-style rail, such as the Omegon 55mm prism rail, which can be used with the MiniTrack. You can then connect and align your astrotracker easily.

Quality made in Portugal

The equatorial wedge is manufactured to the highest quality and consists of CNC components and stainless-steel screws. It is produced in small batches in Portugal and checked for quality.

The ideal addition to your MiniTrack: view the Omegon Deluxe equatorial wedge in the shop now.

Explore Scientific: Guidescope and finderscope in one

February 9 2021, Stefan Taube

Small telescopes which are mounted parallel to the telescope fulfil two purposes: as a finderscope, they help the observer to navigate the night sky, whilst as a guidescope, they help with the astronomical mount’s precise tracking.

Explore Scientific Guidescope 8x50 Helikal

Explore Scientific 8×50 helical guidescope

The manufacturer, Explore Scientific, has produced two models which superbly meet the requirements for both of these:

Both scopes are equipped with a removable eyepiece. Without this eyepiece, they can be used as a guidescope with a helical focuser. They use a guiding camera with a mating dimension of 1.25”. With the aid of the guide sleeve clips, the guidescope can be aligned to a guide star. The camera keeps this firmly in view and corrects minute mount errors using drive pulses.

Using the eyepiece, small telescopes are converted into high-quality finderscopes, producing images vastly superior to standard finderscopes. The eyepiece is fitted with an illuminated crosshair.

Thanks to this practical solution provided by Explore Scientific an auxiliary telescope is only required for different applications.
