For deep-sky photography with long focal length I use an SBIG ST-8XME. It has very good sensitivity, a chip of good size and as main stick has no anti blooming, which is same times a difficulty in photography but an advantage in photometry.
To the camera I attach a filter wheel of CFW10 of SBIG, where I use filters RGB, narrow band and photometry (V mainly).
The operation of the set is good. The only maintenance that has required is every one or two years years carry out a drying operation by putting in the oven the humidity absorbing piece that the camera carries.
For the spectrograph and sun and moon photography I use a QHY IMG2 Pro camera. It has very good sensitivity, and besides the ASCOM driver comes with a very useful specific software with video and life view function. The only problem that I have found is the weakness of the USB and power connecters, so that almost only the weight of the cables is disconnected. I have solved it by attaching a homemade piece that can be seen in the photograph and that firmly fixes the cables to their connectors.
I use a Canon 60Da camera for astronomical landscape photography with a wide-angle lens, Samyang 14mm, and to make "one shot" wide-field photographs with the TSED70Q astrograph. This last configuration I also use for sun and moon photography.
My first camera was an Audine CCD, mounted at home thanks to the excellent design and construction work of the elements of Cristobal García through the Yahoo group "CCD Audine Construction in Spanish". The camera worked very well, with a KAF chip that was prohibitive at that time in commercial cameras. I added a shutter with a small toy electric motor. I still have it operational but with parallel cable, which makes it impractical in the current configuration of my observatory.
QHY IMG2 PRO
Starlight Xpress Lodestar X2
This camera is used for guidance in "off-axis" mode for astronomical photography or as a centering tool and pointed on the photometer. It is a very sensitive camera with a size of eyepiece size of 1/4" very convenient. In the following photo shows the Lodestar X2 camera installed in the photometer.
