The "No EQ" DSO Challenge!
I'm still fairly new to imaging, but have had a good start with Planetary and Wide Field images. Obviously, like most of us, it's the Deep Sky stuff I'd like to glimpse, but time, location and more importantly budget are limiting factors. I currently use an Alt Az platform (Nexstar 6SE) paired with either a webcam (ZWO ASI120 on the Xmas list) or a Canon 600D DSLR and have found SGL forums to be a great source of info and inspiration, but do get a little exasperated when scrolling through thread
As a result of a question on another thread, I've managed to plot (after a fashion) the field rotation rates across the sky. I thought that it was worth posting the map here as well, as it's pertinent to Alt-Az imaging. I've had to use demo software, hence the watermarking, but the overall picture can be seen.
This map shows the number of seconds for a 0.1° field rotation relative to the position in the sky. The physical scale is the wrong way around, i.e. the horizon should be 0° not
