Finally, a universal tracking kit is available, which is easy to assemble and handle. Consisting of a telescopic sight, a tracking camera and the required prism clamp you can start long-term photography with active tracking control (autoguiding). Simply mount the prism clamp with the mounting screws on the carrying handle of the BRESSER Messier and EXPLORE-SCIENTIFIC telescopes and the AR90 / 500 guide scope with tracking camera can already be fixed stably parallel to the main telescope. The tracking camera is now connected directly to the ST-4 compatible autoguider socket of your telescope mount. Connecting the tracking camera via USB cable to your Windows computer and install the camera drivers and any Autoguider software - you can start with the astrophotography. The prism clamp has 2 x 6mm countersunk holes (35mm hole spacing) and 3 further 1/4 "photo tapped holes to allow for versatile adaptation to a variety of other telescopes and adapter plates. The tracking camera is very useful for tracking Recording of planets and even deep-sky objects. A detailed description of the tracking camera can be found at the BRESSER article number 4959050. NOTE: It is necessary to mount the camera on the telescope using the diagonal mirror so that focusing will work.NOTE: The autoguider software is not included. You can use PHD Guiding, Guidedog, Metaguide, Guidemaster (Freeware) or AstroArt, MaxIm DL (chargeable).DOWNLOAD PHD-Guiding: http://www.stark-labs.com/phdguiding.html DOWNLOAD GuideDog: http://barkosoftware.com/GuideDog/index.html FEATURES Universal BRESSER Guiding Kit Guiding-scope, guiding-camera and dovetail clamp included For long exposure Astrophotography with autoguiding Aperture of guiding-scope: 90mm Focal length of guiding-scope: 500mm Screw set for Messier/ES handle included Fits also to many other telescopes SCOPE OF DELIVERY Guiding-scope BRESSER Messier AR90/500 (Art.Nr. 4890500) + Acc. Guiding-camera BRESSER GPCMOS02000KPA color (Art.Nr. 4959050) Dovetail-clamp for Messier/ES/GP/Vixen (Art.Nr. 4910220) Screw-set for Messier/ES handle included USB 2.0 cable (camera to computer) ST-4 cable (camera to teleskope mount) Camera driver software + ASCOM driver Professional ToupSky imaging softwareAperture solar filter for solar observing included

Spare part for Pressure-Tuner of MT and THa series H-alpha solar telescopes from LUNT SOLAR SYSTEMSTwo rubber O-rings are installed into the Pressure-Tuner of Lunt Solar Systems solar telescopes to seal the air-pressure tuning system. Over time, the rubber of this O-rings can age and become porous, whereby the air-pressure can then no longer be maintained. When this happens, a old O-ring can be replaced by this spare part. The replacement is simple and can be done by the user. Installation instructions can be found here under the tab "Manuals" as a PDF file for download.Please be sure to note:Depending on the production series, the diameters of the Pressure-Tuner pistons can vary slightly. There are pistons for O-rings with 32mm inner diameter and 40mm outer diameter, and pistons for O-rings with 34mm inner diameter and 42mm outer diameter. Please check the diameter of your old O-rings, this spare part is an O-ring with 32mm inner diameter and 40mm outer diameter.If you need the larger O-ring with 34mm inner diameter and 42mm outer diameter, this is the spare part with item number 0558340.The LS50THa telescopes have Pressure-Tuners with smaller diameters, for these you will need replacement O-rings with item number 0558320.After replacing a O-ring, the piston and cylinder of the Pressure-Tuner can be re-greased with grease available under item number 0558350.FEATURESInner diameter: 32mmOuter diameter: 40mmCannot be used separately, only as a replacement part on the Pressure-Tuner of MT and THa telescopes from Lunt Solar Systems.It does not matter what blocking-filter is at the MT or THa telescope.SCOPE OF DELIVERYSpare part one O-ring with 32mm inner diameter and 40mm outer diameter for Pressure-Tuner of MT and THa H-alpha solar telescopes from Lunt Solar Systems
