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.

ชุด SVbony 68 Degree Eyepieces Set F9152 สำหรับกล้องดูดาวขนาดฟอกัสเซอร์ 1.25"ทุกรุ่น
The Super-wide Angle Eyepiece eyepieces offer a quality 5-element Plossl optical design at a super affordable price. Fixed folding rubber eyecup allows easy use with or without eyewear. Anti-reflection fully multi-coated optics ensure bright and clear high-images at any magnification, with true color rendition.
The ASI2600MC Duo combines imaging and guiding sensor in one compact body. The main sensor is the Sony IMX571 coming with a native 16bit ADC, 14stops dynamic range and 3.76um square pixel array. The readout noise is as low as 1.0e, and the full well capacity reaches an incredible level of 73ke. And it has no amp glow!
The guide sensor is the Type 1/1.8 SC2210 with excellent NIR sensitivity. The sensor size is 7.68mm x 4.32mm. It has 4umx4um pixels with an array of 1920x1080 and a full depth of 8780e.
The stars on the corner of the guide images affected by reducers back focus distance might not be very round. It is not due to the sensor tilt and will not affect normal use.

ZWO has released a brand-new FF65APO 0.75× full frame reducer with a four-element optical design. It has a reduction factor of 0.75x, which gives the FF65APO f/6.4 astrograph a shortened focal ratio of f/4.8 and a shorter focal length of 312mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging. The back focus distance is the standard 55mm. It also comes with two thread adapters of M54 and M48, and a built-in M48x0.75 2” filter thread, which makes the connection work simple and convenient.
