BRESSER Achromatic 3x (1.25") Barlow Lens

With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.  The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories.  For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR.  This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)

The BRESSER UV + IR Cut Filter makes lunar and planetary images even sharper.Digital astro cameras have a wide sensitivity range that significantly exceeds the spectrum of visible light. Thus, the wavelengths of invisible light in the ultraviolet and infrared are also captured. This leads inevitably to a small additional and of course unwanted blur. The solution is this UV + IR Cut Filter, which allows only light in the visible range 400 nm to 680 nm to pass through and blocks all other wavelengths of light. As soon as these disturbing light waves are cut off, the sharpness of the image and the contrast are increased. Suddenly, details on the surface of Jupiter, for example, can be seen that were previously only barely visible. A clear plus, which can be achieved by this filter.Suitable for BRESSER CMOS cameras and other manufacturers with female camera thread M30 x 0.75 mmAfter removing the original screw adapter with sensor protection glass, the BRESSER UV + IR Cut filter is mounted to the camera instead. This filter has a fine M30 x 0.75 mm external thread for mounting on the camera. The exchange is therefore quick and easy. On the opposite side, i.e. on the telescope side, there is a standard C-mount female thread for mounting other accessories. Note: This filter does not have a standard 1.25 inch (31.7 mm) filter thread.

Enter the world of astrophotography now. With the new BRESSER HD moon and planet camera with ST4 autoguider function. This camera is very good for astrophotography with short exposure times, i.e. for celestial objects like the moon, planets or star clusters. For astrophotography with long exposure times for low light deep sky objects, like galaxies and gas nebulae, we recommend the BRESSER Full HD Deep-Sky Camera (Art. No. 4959050) instead, with it's even higher resolution and sensor sensitivity. Equipped with the new high-sensitivity SONY IMX225 CMOS colour sensor, the BRESSER HD moon and planet camera delivers amazing image results with very short exposure times, even with simple telescope equipment. In addition, this ultra-modern camera can also be used as an autoguider, e.g. to actively track the main imaging device with SLR or CCD astro camera. A universal CMOS colour camera that delivers super-sharp lunar and planetary images in particular. The particularly low noise level of this new chip generation from SONY, ensures an exceptionally high brilliance and no cooling is required. Due to the high native pixel resolution of 1280x980, together with suitable telescopes, very beautiful images of the moon, but also detailed planetary images are possible. The ToupSky pro software included in the scope of delivery not only offers the necessary basic functions for image and video recording, but also many helpful special functions for image post-processing and for setting up the Guider. Functions such as live image display, exposure settings, white balance, dark image capture, stacking, timelapse recordings and much more can be individually configured. Especially the very sophisticated software makes it really easy for you to get started in astrophotography. With the automatic settings, you can produce absolutely presentable results without much prior knowledge. If you wish, simply switch off the automatic settings and gradually venture into the individual professional settings. Connect the camera directly to the ST4 connector of your telescope mount and you have fully automatic tracking control. This makes long exposures of several minutes possible without the stars producing unwanted line marks due to the ever-present synchronisation fluctuations of a telescope mount. A corresponding ST-4 connection cable is even included with the camera. Due to the high light sensitivity of the camera, you will always find a suitable guide star even with very short exposure times. For connection to guide tubes or off-axis guiders, the camera has a 1.25" plug-in sleeve, 1.25" filter thread (M28.5x0.6) and C-mount thread (1 "x1/32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10 / 11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).
