Description

18x300s + 3x420s (111m, 1h51m) on M33 with the SBIG STT-8300M and the AT6RC. no focal reducer or flattener. Astrodon L filter. no CLS filter. CCD was at -30C. ambient temperature ~10-15C.

captured/guided with Equinox Image. guide camera is the CCD built into the FW8G-STT filter wheel. pickoff prism is in front of the filters.

this image has a lot of problems but overall i am pretty happy. mainly for some reason the sensor is *way* off the optical center of the OTA. however, with my DSLR and FR/FF the collimation/tilt is pretty much right on. i have not yet figured out what is going on.

compared with the previous image, you can see just how much faint signal was captured in such a short amount of time.
