The Sky-Watcher HelioFind solar tracking mount is lightweight and ridiculously easy to use. No need to worry about aligning your equipment the night before or early in the morning. Using its patented HelioFind solar finder and built-in GPS, HelioFind automatically levels and calculates the azimuth and altitude of the Sun, all with the single push of a button. Once self-aligned, the mount locates and tracks the Sun for hours at a time. HelioFind is perfect for eclipse chasers, educators who teach science and astronomy during the day, or anyone fascinated with our nearest star.

Tired of wasting half the day not staring into space? Can’t wait until the Sun goes down to start your observing sessions? Need to fulfill those science curriculum standards for your classroom? Already planning your next total solar eclipse road trip? Nothing makes observing our home star as easy and engaging as HelioFind from Sky-Watcher!

You will need a small, dedicated Solar Telescope or small telescope with suitable Solar Filters attached.

Take the Sky-Watcher HelioFind outside on a sunny day, switch it on and it will automatically locate and point towards the Sun and then track it throughout the rest nest of the day. You don't need to align it or carry out any more adjustments

Ideal for observing sunspots, planetary transits, transits of the International or Chinese Space Stations, and solar eclipses with a white light solar filter. Or, attach an H-Alpha solar filter and observe the surface detail of the Sun directly along with tracking the daily changes in stormy prominences, filaments, plages, and even solar flares and coronal mass ejections.

Can be used with any standard photographic tripod (not included)

Perfect platform for Meade Corondo PST or Lunt 40mm, Lunt 50mm H-Alpha scopes.

Sky-Watcher HelioFind Mount is designed for solar observation only.

HelioFind Instruction Manual

Capturing impressive deep-sky astroimages is easier than ever with Celestron’s Rowe-Ackermann Schmidt Astrograph (RASA 11) V2, the perfect companion to today’s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system allows for shorter exposure times compared to traditional f/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.

RASA 11 V2 builds on the legacy of Celestron’s Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s.

Today, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. Optical performance for huge sensors with diagonals of up to 52mm wide is still excellent.

Combine this large image circle with a focal length of just 620mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting.

Optical Performance
The RASA 11 V2 features optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range—or even that of a much more expensive instrument. The design also provides minimal vignetting.

Advanced Features
RASA 11 V2 utilizes the Ultra-Stable Focus System (USFS). At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the sky). The USFS is also compatible with the optional Celestron Focus Motor (#94155-A). The integrated 12V DC MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.

Engineered as a complete astroimaging system, every component of the RASA 11 V2 is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly. The Dovetail CGE bars on the top of the optical tube provides a connection for use of optional accessories like a guidescope.

Introducing the HEM27, iOptron’s revolutionary hybrid harmonic drive mounts. These light weight, high payload tiny titans will deliver an astronomy experience like never before. Imagine a mount head weighing in at 3.7kgs with a payload capability 13.5kgs, without needing a cumbersome counterweight or shaft. Applying iOptron’s multi decade experience creating precision mounts, the HEM27 brings this vision to reality.

Utilizing state of the art harmonic drive technology for the RA movement in tandem with backlash-free DEC worm/belt drive design, the HEM27s deliver unparalleled weight to payload efficiency. Its black anodized all metal CNC machined body is not only appealing to the eye, it’s a rugged platform that will perform at the highest level for many years to come. Unique features such as an electronic friction break and power down memory allow the mount safely stop and resume a GoTo slew or continue tracking even after an abrupt power loss (No need to realign and start from the beginning).
