Purchased things after many reviews online and the 120mm is everything you want. Quality product, easy to set up and easy to use. The service and delivery time from First Light Optics was its usual high standard.

Arrived the day after ordering - FLO really excelled this time. I was a bit unsure how to set the camera up in INDI since my imaging camera is from ZWO too, but once I'd figured it out, it has worked flawlessly. But most importantly, the images produced are really low noise and it makes for a great guiding camera - PHD2 can pick out multiple stars for the multi-star guiding and I'm getting sub-arc second guiding on my AZ-EQ5GT / SharpStar 15028HNT on the first night out after just a quick calibration. I'll probably look to replace the guide camera on my obsy's EQ6R-Pro with an ASI120MM in the future. The only thing that would improve this camera would be the inclusion of a 1 1/4" parafocal ring so that you keep focus more easily after removing the camera for whatever reason, so I'll be getting one when they are back in stock.

Great guide cam. It's simple and effective! It pairs well with my WO 32mm Uniguide scope.

Achieving focus is easy and can be done using the camera's native app. For first time use, I focused it during the day while holding the guide scope in my hand and read the graduated index on my guide scope. Using that as a beginning point, I was able to fine-tune the focus while mounted during the night. Now for daily use, I have the final reading on the guide scope, so I can quickly set it up.

Application support is great. Besides PHD2, I also use it with SharpCap Pro for polar alignment.

Service from FLO and their delivery partner was amazing. Ordered from India, and received on the 4th day!

Bought as a guide cam to use with my ASI Air Pro and ZWO guidescope which were all bought from FLO.

Great camera and ideal for guiding. Easy to focus with the 30mm guide scope and the additional extenders in the box help with back focus.

The normal great dispatch time and excellent service you get from FLO. Long may it continue and hopefully stock levels of astronomy equipment will get better as time goes on. I’ve been after an HEQ5 pro for a while now.

Got this to build a GuideScope using the default Finder provided by Celestron on a lot of their range,
Not fully setup as yet to use as a proper guider, but a combination of the right adapter and the kit provided by ZWO in the package have already made a better.
As i know have a digital finder by hooking directly up to my phone. Works a treat and you can flip the images so they are the right way up and around etc...
Cant wait to use it properly.

FLO recommended this to us to go with the William Optics 50mm Uniscope as a guide scope. Have been using it for polar aligning in the southern hemisphere and the results have been amazing. Will use it for a guide scope one our main telescope arrives.

The camera was super simple to setup and run though the ZWO supplied software - we had it going in less than five minutes (and we are as new as they come to all this technology). Had no problem connecting it to SharpCap for polar alignment and to APT for taking some photos.

All in all this is a great product being used on a guide scope and for the price it is a simple and cost effective solution - especially for those starting out.

As for FLO - I have been spending months firing questions back and forth about how best for my son to get into astrophography and they have been nothing but amazingly helpful. Order was place and shipped within 24 hours and arrived to New Zealand within two weeks (after being stuck in our customs for a week). Package arrived well wrapped and protected and the experience buying from FLO has just been awesome ... have already placed orders for more equipment with them - keep up the amazing work

I'm planning to use it as a guide cam, but still waiting for the RPI4. The delivery was fast from the UK to Hungary, considering the UK is not EU anymore. When everything is in backorder everywhere in the World, FLO has it anyway!

Due to weather conditions I have been unable to try out this camera. However I wish to comment on the fantastic service from FLO. I ordered this item at around 10:00 hrs, it arrived less than 23hrs later at my home on the North coast of Scotland having travelled the entire length of the UK well done FLO and Post Office service.

I was using a Orion StarShoot Magnificent Mini AutoGuider Package. SSAG + Mini 50mm Guidescope for Guiding on my Star Adventurer mount, along with my Nikon Z6 for imaging.
I recently bought an ASIair controller and this would not work with the Orion camera.
So I bought this ASI 120MM Mini camera to use instead.
It is pretty small, light and fitted into the Orion Guidescope perfectly. All the camera and most of the nose tube are out of the scope to focus.
The ASIair recognised the Mini immediately and after focusing, the guiding worked very well.
I have been using a 300mm f/4 PF lens and may try the 1.4 x TC which may or may not be too long.

The camera is great, easy to use and light.
FLO sent it immediately and I am very happy with everything.

Great product and rapid service.
