Explore Scientific EXOS2-GT EQ Mount w/ PMC-Eight GoTo System - Supernova Bundle

SUPERNOVA BUNDLE: For a limited time only, this EXOS2-GT Bundle Package includes a FREE Explore Scientific USB Power Bank. That's a $139.99 USD Value - FREE.

The award winning Explore Scientific EXOS2-GT PMC-Eight Equatorial Mount with its 28 lb instrument payload capacity for astrophotography is an excellent choice for many of Explore Scientific's telescopes as well for the visual astronomer where the instrument payload capacity can be pushed much more, providing a solid very portable solution for those who want to use a larger telescope that would normally require a much larger equatorial platform.

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.

EXOS2-GT w/PMC-Eight

Great mount. Build quality excellent. No issues with tracking and very easy to polar align. Payload capacity for astrophotography is excellent for a beginner like myself. I do recommend getting a smaller counter weight for smaller scopes that weigh less than 10 lbs as the ones that come with the mount are more than 10 lbs each. Haven't had many chances to get out and use it lately due to bad weather but the times I did get to have been enjoyable with little to no fuss setting up and operating. I use NINA and Cartes du ciel to control and set up imaging sessions using a serial cable thru ASCOM and once I figured out how to connect everything I have had zero issues. Highly recommend getting this mount!

Good bang for the buck

Good solid mount for my 8" Cass or 102mm APO, primarily for visual observation. The GoTo system and tablet interface are a bit dated but work flawlessly. Red Carpet ships quickly. Great job!

Purchased about 1 month ago from Red Carpet Telescopes. My first time dealing with Red Carpet and very happy. Service was quick, shipping was fast, and I really like the mount so far. Weather hasn't allowed me to have it out much but the couple times I have, I've been very pleased. Seems like a solid well built mount and carries both my ES AR152 and my Meade LX10 SCT very well. The PMC8 takes a little getting used to but overall works very well as far as I can tell. The only drawback I have is that since it does not come with a hand controller, you will need to aquire a cheap tablet for GOTO control. I started with my laptop but ended up getting an inexpensive android tablet to run the goto software. This actually works just like a wireless touchscreen handpad. I would not hesitate to order from RC again in the future. Thank you for a great experience!
