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.
