The BRESSER Field Tripod ST-3 is a solid and height-adjustable tripod with double tripod leg clamp and made of corrosion-resistant stainless steel. It is suitable for direct usage with the BRESSER Slider Binocular Mount. Adjust the extendable stainless steel tripod to the desired base height and thereby pre-select your favourite observation position. For example, for landscape observation while standing or sitting, the full tripod height should be used. For night sky observation, a lower setting is recommended to ensure a comfortable viewing position while sitting or lying down. The tripod is equipped with a standard GP mounting head and a central screw with metric M10 threaded shaft. It is also suitable for EXOS-1 and EXOS-2 EQ mounts. The upper tripod leg tubes have a diameter of 50.8 mm (2 inches).FEATURESFor usage with BRESSER Slider Binocular Mount Standard GP mount head Also suitable for EXOS-1 and EXOS-2 EQ mounts Solid stainless steel and aluminium structure Double tripod leg clamp Height adjustable approximately from 68 to 110 cm Tripod weight: 5.5 kg Transport length approximately 87 cmUpper tripod leg tubes have a diameter of 50.8 mm (2 inches)SCOPE OF DELIVERYTripod Accessory tray Central spindle

BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results. One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past. Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best. You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter 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).

NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation. The BRESSER Messier N-150s excels with tack-sharp parabolic optics. The 150mm aperture enables you to observe bright nebulas in the depth of space. Find the remnants of a gigantic stellar explosion from the year 1054 in the Taurean constellation, or scan the glowing bands of the great Orion Nebula. Detect the famous Whirlpool Galaxy in the Big Dipper or find the Dumpbell-Nebula in the constellation Vulpecula (little fox). This telescope is only an optical tube without mount and tripod. Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing. CHARACTERISTICS OPTICS Optical design: reflector telescope Mirror diameter: 150 mm / focal length: 750 mm / F/5 Maximum recommended magnification: 300x Telescope for night and solar observation Very high quality Hexafoc focuser with 2,5'' free inner diameter Diffraction limited optics with parabolic main mirror 6x30 straight through viewfinder with reticle Optimized finder socket for comfortable use Cradle rings with handle and integrated piggyback camera holder (1/4 thread) Smartphone adapter for celestial navigation included Dovetail plate with stainless steel rail 50,8 mm (2) to 31,7 mm (1,25) adapter with integrated T2 thread (T2-adapter ring for your camera is needed) SCOPE OF DELIVERY Optical tube 26mm Super Plössl eyepiece (31.7 mm / 1.25'') Integrated 31.7 mm and T2 adapter Prism rail with stainless steel clamping surface Adapter for 50.8 mm (2'' eyepieces) 6x30 optical viewfinder Rotatable star map Aperture solar filter Tube clamp with handle and camera holder Smartphone adapter for celestial navigation Astronomy PC software Stellarium (via download)

​This Vixen focal adapter connects your DSLR or other camera to your telescope with a 60 mm thread.The large interior diameter of the adapter prevents vignetting at the edges of full-frame camera sensors.The focal adapter can be rotated so that the image field can be perfectly framed.This rotational adjustment is facilitated via 3 locking screws, ensuring a firm lock.Note: Vixen T2 ring is also required for your brand of camera.In this case, the inner ring of the T2 adapter is removed and clamped in place with three small grub screws.PROPERTIESConnects your DSLR camera to your telescopePrevents shadowingDimensions: 72 mm x 20 mmWeight: 55 gWHAT'S INCLUDEDFocal adapter universal 60 mmAssembly tool
