I must say the delivery by FLO was excellent, with DPD delivering right on time. I have used the camera twice on the Sun and the images were amazing, first at max resolution and then with the ROI option. Canít wait to see what I get from the moon.

Great little mono cam
18 March 2022  | 

I bought this specifically for solar imaging, even though I read some people had problems with artifacts in extreme narrowband. So far, I have not seen any problems when imaging with my Lunt 50mm, or my 102mm Lunt mod. I recently started doing EAA imaging, and this little gem even does that well (I have only gone up to 30 seconds so far)! No problems with drivers, camera runs great in SharpCap.

Great planetary / lunar imaging camera
20 January 2022  | 

I got this camera specifically for getting back into lunar imaging with my StellaLya 6" Cessegrain, and installed into my Beelink mini PC. The intention is to have a more mobile rig as my house is in the way for the planets and most of the moon phases!!

Straight forward and easy to install -as was the ZWO software - and it does exactly what it says on the tin! With an SSD in the miniPC I was easily able to achieve the quoted FPS values. So far, tested with FireCapture with no issues at all - really looking forward to grabbing lots of lunar data to process!!

And, you also get the additional 2.5mm lens so it can double up as an allsky camera should you wish!

Very pleased - And ss always, delivery was super quick from the FLO team!
