    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.

Best OSC camera for the price!

I've had this camera since early 2021 and it has made the world of the difference in my images! I used to use a sony a6400 mirrorless camera and it just gave me headaches. This camera picks up so much more signal in the Ha and overall more details in any image. If you are deciding whether to switch from a dslr/mirrorless camera to a dedicated astro camera, this is the one that would recommend to a close friend. It does suffer from amp glow, but dark frames will correct it right out. Dark frames are so much easier to take with cooling built into the camera also. I paired this camera with the Optolong L-Extreme filter and it captures bright nebulae no problem. It takes longer integration times for fainter nebulae compared to a mono camera, but much simpler because of the OSC pictures, but much better than a dslr/mirrorless system. Pair this camera with a narrowband filter and an ASI Air and astro imaging becomes much easier and more enjoyable. Clear skies everyone!

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.
