"This just makes me even happier with my purchase of a EXOS2-GT, I've come nowhere near capacity with mine. But this is just a very reassuring example of the quality of Explore Scientific products, and another reason why I will continue to be a customer!"
We often get calls about the “load capacity” of our mounts. For telescope tracking mounts there are generally two different specs: instrument payload capacity for astrophotography, and instrument payload capacity for visual use.
Payload capacity ratings for visual are normally much higher than for astrophotography because with added weight beyond a certain point, there is an increase in tracking error (e.g. periodic error, etc.). For the EXOS2 GT PMC-Eight the instrument payload capacity for astrophotography is 28lbs + counterweights. And for visual use, the instrument payload capacity is 40 lbs + counterweights.
Note that we chose stepper motors for the PMC-Eight instead of DC servo motors because they can handle incredible strain and not damage mechanical nor electronic components.
Explore Scientific's PMC-Eight GOTO system can be controlled wirelessly or wired with a tablet or PC, with Windows 8.1 or 10, Android, Amazon Fire, or iOS, with a free app called ExploreStars. Tablet must be purchased separately.
The ExploreStars App controls any PMC-Eight mount by means of an intuitive graphical interface. Among other features ExploreStars offers both 2-star and 3-star alignment procedures, educational information and images of the more popular celestial objects, and a choice of over 80,000 objects for viewing.
The ExploreStars object database encompasses a wide range of celestial objects including those in the Solar System, the Messier Catalog, the New General Catalog, and the Index Catalog, as well as a collection of over 70,000 stars. The Celestial Database also includes educational material and images for many of the more popular objects. This database is available as a separate updatable component of the ExploreStars software system. It can expand over time and any ExploreStars implementation can easily be updated by downloading a fresh copy of the Celestial Database. In fact, the educational material and images within the database can be customized by each individual user using Microsoft Access.
In addition to ExploreStars, we provide an ASCOM interface that will allow a huge range of star map software to control the PMC-Eight. Here are just are some examples that are currently available: ACP; APT; AST / ATC & Ricerca (Omega Lab); AstroArt; AstroMB; Cartes du Ciel / Sky Chart; CCD AutoPilot; DeepSky; Deepsky Planner; DFM Engineering; Earth Centered Universe Pro; EasySky; Eye and Telescope; Project Pluto; Hallo Northern Sky; Maxim DL; MaxPoint; PinPoint Astrometric; Prism; Sequence Generator Pro; Sidereal Technology; The Sky; SkyMap Software; SkyTools 3; Star Atlas PRO; Sky Observer; StarryNight; Stellarium; and Virtual Moon Atlas.
Explore Scientific USB Power Bank with Red LED Flashlight - ES-PBFL-01
With the new Explore Scientific USB Power Bank with Red LED Flashlight, you will have power to spare for your telescope mount, smart devices, cameras or other equipment in the field. This reliable rechargeable Lithium-Ion battery has a capacity of 8300 mAh with an output of 12v that connects to a supplied power cord with spring-loaded power plugs with 5.5mm x 2.5mm to 5.5mm x 2.1mm connectors. The 5v output from the USB port can power your devices with a standard user-supplied USB cable. The Explore Scientific USB Power Bank with Red LED Flashlight has an operating range of a teeth chattering -4 degrees to a blazing 140 degrees Fahrenheit!
The soft deep red glow from the LEDs lets you see under dark starlit skies without ruining your night vision as you make adjustments to your equipment, read star charts, locate that small telescope part you dropped in the grass, or find that steamy hot cup of coffee before you knock it over and spill it in your lap.
Slightly smaller than a building brick and weighing only 1.4 pounds, the rugged rubber covering protects the battery from minor impacts and seals the red LED flashlight on/off switch from dirt and moisture. The five level indicator shows power availability. The unit is turned on or off with a toggle switch. A convenient 2-point attachment point allows you to hang the battery near your equipment.
Aside from use on the star party field, the Explore Scientific USB Power Bank with Red LED Flashlight could be the best portable Lithium-Ion battery pack for off-grid camping. And in the case of power outages, natural disasters, or invasions from extraterrestrials— is perhaps the best portable emergency power to keep in your car, home, or office.
How long can it power the Explore Scientific PMC-Eight GOTO system? Our field tests with the iEXOS 100 and EXOS 2, with a draw of 0.5 amps (0.6 amps when slewing) is about 8 hours of running time. For the Explore Scientific/ Losmandy G11 which draws about 50 percent more, we expect that it will have a running time of about 5 hours. Your time would be reduced if you are using the USB port to charge a phone or other device, or if you are using the flashlight.
Typical full charge time is 5 to 6 hours from a full discharge. Comes complete with 110v - 220v AC to DC wall plug charger and power cord with spring-loaded power plugs.
