iOptron HEM27 Slew Demo (with Celestron 11" OTA with no counter weight):
Introducing the HEM27 and the HEM27EC, iOptron’s revolutionary hybrid strain wave drive mounts. These light weight, high payload tiny titans will deliver an astronomy experience like never before. Imagine a mount head weighing in at 8.15lbs with a payload capability 29.74lbs, 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 strain wave 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).
A HEM27 mount can be controlled by a computer, either via ASCOM/Commander for a Windows PC or a third party INDI driver for a MacOS software; a SmartPhone/Tablet via iOptron Commander Lite or an App like SkySafari; or a Raspberry Pi device via INDI driver.
The HEM27EC features a high precision RA axis encoder that delivers incredible tracking accuracy, enough that many will choose to image “sans” guiding.

Levenhuk Zeno Handy ZH37 is a classic handheld viewing magnifier. It comes in useful for reading small font text, examining tiny details on photographs and engravings, and studying miniature objects. This magnifier is a great assistant for a student, jeweler, engineer, and watch repairer. It is also suitable for general use as well as for solving professional tasks.
ตัวแปลง SVBONY Prime Focus + Variable Eyepiece Projection Camera adapter, 1.25"
Composed of two detachable parts: a prime-focus adapter for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography.
Supports maximum of 42mm eyepiece diameter
Connects with SLR & DSLR Camera for Eyepiece Projection Photography
Has a handy laser engraved Extension Scale
The 1.25-inch Extendable camera adapter is made of black anodized aluminum and is suitable for all standard 1.25" astronomical telescopes
Easy to connect camera body (needs T-Ring) to a reflector or refractor telescope for either prime-focus or eyepiece-projection photography.
1.25'' barrel is threaded to accept standard 1.25'' eyepiece filters
A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a sliding barrel design that allows variable projection distances.
Built-in protective pressure ring to prevent eyepiece barrel from being scratched
T-adapter for 23.2mm (0.91") to M42x0.75 male thread, fit for microscopes with standard 23.2mm focusers
Made of machined anodized aluminum, the inside of the adapter is fully baffled to minimize reflections
Connects with specific camera brand's T-ring adapters (sold separately) to connect your 23.2mm microscope focusers to your Nikon/Canon/Sony/Olympus/Panasonic etc. cameras
For filter wheels that accept 36mm unmounted filters
Compatible with ZWO/QHY/SBIG 36mm electronic filter wheel
Suitable for DSLR, webcams, CCD cameras, planetary cameras, black-and-white camera for bright-field shooting
Long-lasting: made with multi-coated glass with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength
Improve image sharpness, blocks ultraviolet and infrared transmissions but lets visible spectrum through
comes with a plastic case With high pressure EVA case lining
Quickly capture dark frames to optimize photo quality
Opaque - blocks all light from the imaging camera sensor. Help remove dark currents - essential for astrophotography
Easily eliminate camera noise and hot pixels
Dark frame acquisition helps remedy such noise and "hot pixels" by canceling out these disruptive effects during image processing
Threaded and can be directly connected to your filter wheelfor fast conversion between different filters;
Made of metal for durability. High quality packing box includes foam-lined plastic case
The L-Ultimate is a 3nm dual band filter designed to drastically reduce the effect of light pollution. The 3nm isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue). It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere, maximizing the transmission of the main emission lines of the nebula in OIII (496nm and 500nm) and H-alpha (656nm). Used with DSLR, color/MONO CMOS and CCD, this filter is suitable for telescopes with an f-ratio of f/4 or higher (slower).
