For many of us who struggle to find adequate polar alignment in the Southern hemisphere, especially in light polluted areas is no understatement.
There are a few apps out there that offer some solution to help find and maintain polar alignment.
Last year I purchased the QHY Pole Master camera and it made a vast improvement and may I say less frustrating in locating the southern polar axis. Although the software provided by QHY is fine and it does the job.
I found that using the paid version of Sharp cap with the Pole Master camera was much quicker in locating Sigma Octants ( on average around 6 minutes)
You don't even require the QHY camera a good quality webcam and a 50mm guide scope will also complete the job. Sharp Cap has a dark subtraction feature that helps the S/N ratio .
The QHY Pole Master is very sensitive Mono CCD camera with a wide angle lens as standard.
