My current imaging setup had two deficiencies; short focal length for galaxy season and non-cooled camera for hot nights.
The short focal length deficiency has a compromising, but effective remedy. Astro-physics updated their Barlow to the Advanced Barlow which is more corrected for photography with APS C sensors. The 2x Barlow provides a flat field across 80% of the sensor.
The non-cooled camera was solved by the new ZWO ASI294 MC Pro. A cooled CMOS sensor in a 4/3 format which matches well with my Canon T5i.
Main reason for this camera...
- one shot color. I don’t want to mess with multi-filter images.
- 14 bit dynamic range
- ability to control via WiFi on iOS device via ASI Air.
First test of this setup was last last week with excellent results. I was able to achieve a nice image scale on M51 that I believe is better than simply enlarging a shorter focal length image.
And I LOVE utilizing the iPad for image control of the camera!!!!!
