Although the imaging camera is different, this one showcases the versatility of the ASI224MC, used here as a guide camera, on an OAG, at F10 (FL 2,000mm), and with typical suburb light pollution, a very difficult guiding environment.
The 224mc had enough sensitivity to allow PHD2 to do 0.5s guide exposure and managed to get some surprisingly good tracking out of the $800 Celestron AVX mount.
16x300s Red, 9x300s darks. Celestron C8, Celestron OAG at native F10. Imaging chip is the same as ASI120MM (small, 1/3 chip), but a different brand that has cooling (-20c) and motorized filter wheel.
