Overview
The QHY5III715C is an ultra-high resolution, back-illuminated color camera with extremely low read noise. The sensor has a 1/2.8-inch optical format, similar to the QHY5III462C. However, the QHY5III715C has four times as many pixels as the QHY5III462C, offering 4K resolution with 1.45μm pixels.
This makes the new QHY5III715C ideal for smaller, short focal length refractors. The exceptionally small pixels provide a field of view (FOV) of less than 1 arcsecond at focal lengths of 12 inches (300mm) or longer. The QHY5III715C inherits all of the updates and improvements of the QHY5III Series Ver. 2 line of cameras.
Extended Near-Infrared Sensitivity
The latest sensors feature deeper pixel wells, enhancing sensitivity to red and near-infrared (NIR) light. These sensors achieve peak NIR sensitivity nearly equal to visible light.
512MB DDR3 Buffer
The QHY5III (Ver. 2) cameras include a 512MB DDR3 buffer, doubling the memory of many deep-sky astrophotography cameras with 256MB. This reduces computer transmission load, ideal for high-speed planetary imaging.
New Front-End Design
The redesigned QHY5III (Ver. 2) cameras offer improved compatibility with a slim 8mm BFL, making them easy to integrate with off-axis guiders (OAGs). The 1.25-inch threaded adapter supports filters and interchangeable top glass allows seamless use of CS or C-mount lenses. A 1.25-inch filter wheel adapter connects monochrome cameras to QHYCFW3-S filter wheels.
USB 3.2 Gen 1 Type-C Interface
Upgraded to USB 3.2 Gen 1 Type-C, these cameras offer better durability and flexibility than the previous USB 3.0 Type-B. Use high-quality cables to avoid performance issues.
Universal Guiding Interface
The cameras now feature an ST-4 compatible guiding interface, replacing proprietary designs, allowing easy replacement of guiding cables at low cost.
Indicator LED
An indicator LED at the back signals camera status using different colors for diagnostics. It remains off during normal operation to prevent light contamination.

Had difficulty obtaining monthly star charts as stated but eventually received response from AG at Canty Uni

My first purchase as I am new to stargazing. These binoculars a great start. Quality product at a good price. Looking forward to my next purchase as I look for even better views.

Bought this for archery. It is heavy but what that’s what I wanted. It is solid in the ground and will not be blown over. I have accidentally knocked it with my bow when shooting and the scope has not moved a millimetre. Perfect!

I purchased this as a mount for an 80mm refractor. The aim was for something relatively portable that could be used in the field. So far it works well and should be ideal for the job. Being able to control the mount with an iPad using Commander Lite is helpful.

It’s my first scope, so it’s baby steps when the sky allows

The QHY MiniCAM8M with the IMX585 sensor and a full set of LRGB and HOS filters is the perfect way to get into mono imaging. It got me into it ;-)
The resolution of a mono camera is fantastic and works perfectly with my Askar 103 APO refractor.
My first LRGB was only 2h integration (clouds!) but would have been impossible with my OSC (ASI294MC): https://app.astrobin.com/u/Z3ph0d?i=id2xfw

I bought this book on a whim when I popped into the store (to buy an eye piece), not expecting too much ... instead I was pleasantly surprised, it is a great book, very interesting, and really well written so that novices like me can understand it too! I thoroughly enjoyed reading this book and keep using it as a reference guide for my stargazing nights. Highly recommended!

This was the first time I walked through the door (after only recently picking up my love for astronomy again) and the service, advice and prices were great! I’ll be back!
