I’ve been trying to get an OAG working with my original ZWO 120mm mini, with very limited success - but it worked perfectly with a guidescope. Most other OAG users recommended the ZWO 174mm as THE guide camera of choice for an OAG, but I just couldn’t justify the price (over £400) Luckily, ZWO have brought out the 220mm as a midrange camera to slot in between the 120 and the 174. Not quite as large a sensor as the 174, but a big increase on the 120. It seemed to have favourably reviews, so I took a chance and bought one. Does it work? Yes. First time out, I have stars and good guiding, that I never had with my 120. Imaging on my StellaLyra RC8, I get sharper, more defined stars than I was getting using a guidescope, due to the more accurate tracking through the OAG, ...

As always with a ZWO camera, just plug it in and your ready to go. I bought this model because my 120MM was struggling in my Celestron OAG. The performance improvement going to the 220MM for use in the OAG was IMMEDIATELY noticeable. Finding stars with it was no problem. I went with the 220MM because I did not believe I needed to go with the 174MM...at least not yet. I have had very limited use with the 220MM because of mount issues, but with the minimal time have had to use the 220MM, so far I am very pleased with it. Sometimes when you get something and "test it out" you know right off the bat you've got a winner.

I have had the 120 guide camera from ZWO for a while and it was good. It is not in the same ball park as the 220. My guide numbers improved almost 50% just on this camera swap. I was amazed. The bigger more sensitive chip makes a difference. Much more than I would have thought. To top it all off Agena got it to me in 3 days. From CA to NC. When you place an order with Agena they get it out the door faster than anyone. Unlike others they don't sit on the order a day of two. They get it out the door on the road in hours and its free shipping. I have no other dealer as fast to ship. I can highly recommend the ZWO 220mini camera and Agena Astro.

I image in a Bortle 8/9 backyard and have been using the ASI 120mm guide camera for over a year. It has performed well but during galaxy season where stars are not very prominent or bright for guiding, I began to have issues even getting a star to show up and guide on. I read that this camera has a better sensor so I tried it. Without a doubt, I was able to at least get at least one good star to show up and guide on with better guiding as well. In my opinion, it is worth the extra price over the ASI120mm. I’m still using the 120mm on a 2nd rig but it’s nice to be able to guide in an area of the sky that is a bit sparse on bright guiding stars.
I bought this guide camera to replace my aging Orion SSAG. I frequently could not use multi-star guiding due to it's low sensitivity.I received the 220mm mini and installed it on my Orion 50mm guide scope.Wow, what a difference! Plenty of stars for multi-star guiding!Installed it on a ZWO OAG. Installation went well. I also have 8-9 stars available for multi-star guiding besides the auto-select guide star.Excellent camera!
Using this coupled with ZWO's 30mm f4 guide scope, cold-shoe mounted on a DLSR body with 600mm lens, with ASI Air+ controlling a Star Adventurer GTi. Super light camera, kept it all well within the load limit of the mount. Easy to focus the guider. First time autoguiding so can't compare it to anything else, but all in all an absolute game changer in length of exposures and resulting quality of my DSO photos. No problem guiding on the head of the recent comet for great shots of it. Choose it as an intermediate resolution and price compared to alternatives. Highly recommend it for this purpose.
I was using a zwoasi 120mc planatary camera for my guiding until I decided to go to off axis guiding and then I knew I would need a better camera. I read all the reviews and decided to get the ZWOasi220mm camera. . . WOW what a difference. . . it's a really sensitive camera, picks up plenty of stars , even in an off axis guider. I also use it on my 50mm x 190mm guide scope on my refractor and it does a great job. If you plan to do any off axis guiding ( if you use a C8 you should) then this guide camera is a must. Highly recomend it. . .
I’ve started using the Antlia OAG with integrated filter drawer and had originally begun with my existing 290 mini guide camera. However on some dimmer targets I couldn’t acquire a suitable guide star. So I purchased the 220 with its larger sensor to give more fov. This appears to have worked and it is now good to go. Sensitivity is really good, with near IR capability. Excellent service as always from FLO!
I bought this to replace an ASI120mm mini guide camera that I was using on a 480mm refractor with an Orion TOAG. The ASI120 was functional but usual only had a couple of stars and would lose the guide star once in a while through the night. The ASI220 has plenty of star so picking a several good ones is much easier. I would say the guiding accuracy has not changed much, but the reliability has change a lot.
I used this camera with my Askar OAG along with my ASI533MC Pro camera. This camera had no problem finding suitable guide stars. Guiding was sub1arc second. It was worth the extra money to have a reliable guide set up with my ASI533MC Pro.
