Transformed imaging
Tuesday, 22 September 2020  | 

I have had this camera for a few weeks now and am slowly getting used to it.
My planetary and lunar imaging has been transformed. The move from a mirrorless camera (Sony a6300) means that being able to stack video gives a far more detailed product.
I need to work on the deep sky capabilities but that is more mylimitations than the camera.

Perfect color camera for planetary photography
Wednesday, 5 August 2020  | 

Used this camera to get fantastic images of Jupiter and Saturn through a 1200mm focal length refractor and a 3x barlow. Great framerate, nice colors. Works great with FireCapture software.

Easy to use and I really enjoy what this camera can do. The settings/features/options on this camera is really cool like recording RAW video, recording without debayering the colors, High FPS and custom resolutions. Good infrared performance and many options for filters and barlows/teleconverters. I get very high magnification and the camera sees full spectrum with colors by default and with good performance. Amazing live view on my computer. For terrestrial view I get good image wih extreme range, especially with barlow/teleconverter. It is not 4K because it need a smaller sensor with large pixels for high magnification and sensor noise performance. Buildt for planetary viewing but works for anything you want to do with it. I am very satisfied. Tested with ZWO 850nm IR Pass filter and it works very well.

What a great little camera
Wednesday, 25 July 2018  | 

Very impressed with how flexible this camera is. Good resolution and easy to use. Have used it on the Moon, Jupiter, Saturn and a few deep sky objects as well.

Definitely need an IR/UV filter with as it is so sensitive in the infrared that everything gets a pink tinge otherwise. But as a result it works well with an IR pass filter which gives great results for daytime imaging of the Moon and planets. No reason to stop imaging during the summer twilight months here in Scotland now.

FireCapture works well with it and I prefer to use that for lunar/planetary captures. SharpCap Live Stacking gives good results for deep sky objects. The camera is uncooled so I keep the exposures relatively low (less than 15s) to keep the noise down but get some pleasing images this way. You will never get the best deep sky images using this method but that's not what EAA is about (I use a cooled CCD for that). But you do get instant images of a lot more objects this way.

I'm surprised at just how good this camera is and really enjoying using it.
