LUNT LS100FHa/B600d1 H-alpha solar filter

The Explore Scientific Two Room Pop-Up Observatory is a useful weatherproof tent that protects your valuable equipment from wind, dew, rain and dust. Most amateur astronomers and astrophotographers dream of having an observatory to keep dust, dew and wind away from their telescope and to shield disturbing stray light from their telescope's optics. But for many astronomers, an observatory is only a dream because of the cost of a roll-roof building or an observatory dome. There is also the problem that an observatory building needs a permanent location that is suitable for an observatory. Portable, quick to set up and inexpensive A good solution is a portable observatory tent. Compared to their fixed counterparts, a tent is extremely inexpensive and can be set up almost anywhere there is a flat surface and a clear view of the sky. However, setting up a portable observatory tent can also be a hassle. No one wants to waste their valuable observing time reading complex instructions while trying to figure out which pole goes where. For this reason, we have used a sturdy pop-up design. Setting up the EXPLORE SCIENTIFIC Pop-Up Observatory can be done in a matter of minutes. By releasing a retaining strap, the complete tent unfolds from its packaging in just a few seconds. You really don't need to do anything other than connect the two observatory rooms with a Velcro seam and attach it to the ground. Thanks to this simple design, the EXPLORE SCIENTIFIC Pop-Up Observatory can be set up and taken down in just a few minutes, giving you plenty of time to enjoy your astronomy weekend. Plenty of space for your equipment and super compact when folded up. With just under 5 square metres of total space and 1.52 metre high side walls, coupled with 1.83 metre high windscreens, the EXPLORE SCIENTIFIC Pop-Up Observatory allows you to set up your computer equipment in one room and the telescope in the other, or set up two complete telescope systems. Each room is 152 by 152 centimetres. Mobile observatory with compact transport dimensions In addition to being easy to set up and take down, another advantage of the pop-up design is that it is travel-friendly, as it is light and easy to stow away. The entire observatory tent folds down to a package 70 centimetres in diameter and 10 centimetres thick. This allows it to be transported in a small car or even on a flight for distant expeditions. And apart from the fact that it allows you to go to your favourite observing site at any time, portable observatory tents are usually the first choice for astronomers and astrophotographers attending star party events.  Advanced materials provide optimal protection and durability However, the fact that the EXPLORE SCIENTIFIC Pop-Up Observatory is lightweight and easy to store and set up doesn't mean it can't withstand bad weather conditions. The Black-Out coated polyamide material is waterproof and offers excellent UV protection. This guarantees reliable protection for your equipment as well as long-lasting durability of the observatory tent. Large doors for convenient use The doors to enter the observatory tent and pass through the attached rooms are very generously sized at 102 centimetres high and 92 centimetres wide, so you can easily walk in and through your equipment. The doors roll down to keep moisture out and their heavy-duty zips will last for years. The extra weather cover protects your gear when not in use. With the large weather cover included, you can protect your gear from the hot sun or a surprise rain shower during the day. Or even from dew at night. The modern, coated and waterproof material keeps all unwanted weather influences away from your equipment. Included are cords and pegs to tie down the tent. The structure also has additional holding straps for the use of heavy-duty straps, which can be purchased at local hardware stores.

The iEXOS-100 is a complete astronomical computerized Wifi or Wired GOTO Equatorial Tracker with integrated PMC-Eight electronics suitable for attaching Small Telescopes or DSLR Cameras attached to a standard Vixen Style Dovetail Plate. Also a ST-4 compatible autoguider port for active tracking control is included. Use with the free ExploreStars App for Tablets (Windows, Android, iOS), or with the free ASCOM Standards Compliant POTH Client from Explore Scientific (either wired or wireless) to work with virtually any sky software that supports ASCOM. The iEXOS-100 utilizes a proven German equatorial mount design and Explore Scientific’s revolutionary PMC-Eight™ motion control system to flawlessly navigate the night sky and track objects as they journey across it. This combination provides superior observing and imaging performance without a prohibitive price tag. GOTO systems play an important role in the world of amateur astronomy because they ensure users spend less time searching for particular objects and more time observing and imaging. The PMC-Eight with its versatile connections supported with free to download apps for Window, Android, and iOS, or through the free to download ASCOM POTH Client to connect to your favorite ASCOM Compliant Astronomical Software, can allow you to control the telescope from a few feet away or by communicating computer-to-computer with an Internet connection from virtually anywhere in the world. One of the standout features of the iEXOS-100 system is its German equatorial design. When it comes to tracking the stars with a telescope, there is nothing that compares to a German equatorial mount because it will follow objects as they rise in the east and set in the west. For observers, a German equatorial mount makes it easy to keep your celestial target in your eyepiece. For imagers, it helps you avoid common astrophotography pitfalls like field rotation. Before you can track an object, you need to find it, and that objective can be daunting when you’re faced with a vast expanse of inky black sky. The iEXOS-100 puts a powerful GOTO system in your arsenal of astronomical tools that takes the frustration out of navigating the night sky. This integrated version of Explore Scientific’s PMC-Eight™ system transcends the industry standard single processor by utilizing eight CPUs that operate independently of one another to focus on defined functions. This delegation of tasks among the processors results in a system that offers superior responsiveness, efficiency, reliability and astoundingly fast timing intervals for seamless images and accurate tracking. Although it is internally complex, the GOTO system can be easily operated from your own Apple, Android or Windows tablet using the ExploreStars app, which has an intuitive nature that makes it simple and quick to align your telescope, navigate the stars and learn specifics about tens of thousands of celestial objects. This dynamic app is fueled by a database that is routinely updated to ensure it remains a relevant resource. Our commitment to creating a streamlined GOTO mount is obvious in other design choices. The iEXOS-100 has locking clutches that will let you quickly reposition your telescope from one side to the other and an altitude knob for smooth height adjustments. The mount base includes a small polar alignment tunnel that allows users to roughly align their observing setup with Polaris. It also has a simple bubble level that comes in handy when stabilizing your tripod. Other features include a bracket for holding the battery pack, which powers the PMC-Eight system™ through 8 C batteries (not included); two 1 kg counterweights for balancing; and glow-in-the-dark markers on certain points of the mount and tripod so you can stay oriented with your setup at night. The mount is designed to hold up to 5 kg of astronomical equipment.IMPORTANT NOTETo start using ExploreStars app, download the free app and download the celestial data set that contains the astronomical catalogs, reference images, and reference text. Simply by unzipping the ExploreStars folder containing the expanded celestial data set into your Pictures directory, you will expand the native database from a thousand objects to over seventy thousand objects.  SOFTWARE DOWNLOADhttps://explorescientificusa.com/pages/software-and-downloads-for-pmc-eight-systemFEATURESIntegrated Explore Scientific PMC-Eight™ Wifi GOTO systemBeautiful full graphical user interface using our very own ExploreStars OpenGotoWifi controlled by Tablet, Notebook or Desktop PC with 7'' or larger display, and Wifi function (computer device not included)Needed system software of optional computer or tablet: WIN8.1, WIN10+11, iOS, Android 4.4 or higherClassic four-button pattern and virtual joystick for guiding, centering, moving and slewing on the touch screenIntuitive 2 star and 3 star alignment procedure Includes a small polar alignment tunnelStandard Vixen Style Dovetail AdapterMount load capacity up to 5 kgMultiprocessor Micro Controller with 8 CPU´sMicro-Stepper Motors and worm gearsSilent Belt-Drive System Mini-USB port for INDI/ASCOM wired computer connectionST-4 compatible autoguider portINDI and ASCOM Driver available: YES, supports also Pulse-GuidingYOU can write your own code and import it into this softwareGPS-compatible and auto time / date settings are dependent on optional receiver on computer, tablet or phoneGlow-in-the-dark markings on mount and tripodWeight mount-head: 4,0 kg ; weight tripod: 2,5 kgSCOPE OF DELIVERYExplore Scientific iEXOS-100 PMC-8 Wifi Goto MountStainless steel tripod with bubble levelCounter weight 2 x 1,0 kg Battery compartment 12 volts with bracket / (8 x C-Cells not included) Coil-cord for DEC motorGlow-in-the-dark markings on mount and tripodExploreStars Software via download for freeInstruction manualIMPORTANT NOTE: This package doesn´t include any WINDOWS/iOS/Android Computer or Tablet.FAQ / KNOWLEDGE-BASE:  https://explorescientificusa.com/pages/explore-scientific-knowledge-base-and-faqsPMC-Eight GROUPS:  https://espmc-eight.groups.io/g/MAIN
