    • The first image sensor to take on the four-thirds format providing the necessary amount of pixels for better images.
    • Low-illumination performance from its large optical system makes it ideal for astrophotography.
    • Minimize your camera's amp-glow with improved and reliable data transfer using the DDR memory buffer.
    • Achieve a high signal-to-noise ratio with just one single exposure!
    With exceptional noise reduction technology and video capabilities, the 294 Pro is ideal for photographing: Nebulae, galaxies, planets, solar images,  lunar images, and more.

    Sony IMX294CJK HCG Mode

    Reduce your camera's read noise levels to lower settings at higher gain without loss to the dynamic range when in HCG Mode. Its automatically enabled when the gain setting is 120 or higher. See your camera's read noise drop under 2 electrons, while the dynamic range will remain at 13 stops!

    ZWO ASI Short Back Focus 

    Most Adaptable Camera Body

    Like most ZWO cooled cameras, this 294 Pro body has a short back focus of 6.5 mm. This makes it very easy to adapt to almost any telescope system. Especially telescopes or reducers where back focus is very scarce.

My first dedicated Astro camera

Haven’t been able to use it yet due to cloudy skies at night. However, the weather is starting to clear so I’ll be getting to use it soon.

Should have bought this off the bat

Originally purchased the 294MM and the assorted filters and wheel, but I wish I had just started with the MC. I was just worried there wasn’t going to be a huge difference from my DSLR and I figured I could still use that if I wanted to shoot color. Boy, was I wrong. Don’t misconstrue; I do very much like the mono camera and the filters I purchased will allow me to grow I to them, but my learning curve needed to be focused on equipment setup, planning, and learning pixinsight… and not on mono workflow at this time. I went through about 4 months of solid work trying to figure out my mono capture and post processing and finally I broke down and purchased the OSC version. That night I got first light and the next AM I had clean data and a way better image than I had been able to conjure previously. I will grow into the mono equipment but for now it is off to the side. For those who are fairly new to astrophotography and think you want to jump straight from DSLR to mono, I would HIGHLY recommended this one-shot color camera. The jump up from DSLR is epic, it is only a slightly smaller sensor than an APS-C format at less than half the price. You will not be disappointed.

Great addition to my rig!

This is my first dedicated astro camera and I am thus far impressed with it. It is very easy to use and works flawlessly with APT. The first picture I captured with it blew me away. I was not expecting to get such vibrant detail shooting into a wall of light from my Bortle 8 backyard. I am really looking forward to seeing what I can do with this camera from a true dark site!

The camera is great and simple to set up. I am still awaiting the ordered power supply which was NOT included with the delivery In the coming warmer months, the power supply is a must! Thanks. Ed.
