My current camera, an aging ST-8XE, is in the shop for repair so I am looking at replacing it with a new imager for my photometric imaging. Would appreciate the benefit of your experience in making this decision.
Interests: Photometry of short period and eclipsing binary variables. Possible additional targets: Exoplanet transits, asteroid light curves or other photometric targets.
Equipment: C925 OTA currently working at 1645mm. Imager, which is out for repair, ST-8XE. TCF-S focuser. Using guide scope and camera, would prefer OAG. This camera has been great for photometry and while the chip is a bit small the FOV for photometry has been adequate. But being 20 years old now I think it is time for me to prepare for the inevitable need for replacement.,
I have been looking at cameras that use the IMX694 sensor, either:
Starlight Xpress Trius Pro-694 CCD Camera Combi with Midi Filter Wheel and Lodestar Pro – Blue
SBIG Aluma CCD694 with filter wheel. Approximately an additional $1,800 cost.
Is anyone out there using the IMX694 sensor for photometry, or have considered and rejected this sensor?
What about experience with these two cameras and their manufacturers? Other manufacturers?
Recommendations for other sensors and/or cameras?
Thanks in advance for assisting me with this decision.
