47 Tucanae again - some better images
I have had another go at shooting 47 Tucanae, now that I have a better idea of exposure settings, etc.
The following images are shot on my ZWO ASI120MC camera mounted on my 130 mm aperture Newtonian (650 mm focal length), with Sensor Gain set to 50%, to avoid "overloading" the sensor, with exposures of 5, 10, 20 and 30 seconds respectively.
They're not perfect, but I'm pretty happy with how it's coming along! My focus is much better this time, and you can see a little bit of colour too.
